  • Deletion of monoamine oxidase A in a prostate cancer model enhances anti-tumor immunity through reduced immune suppression - Biochem Biophys Res Commun 2022 Oct 6 - "We have previously shown that monoamine oxidase A (MAO A) mediates prostate cancer growth and metastasis. Further, MAO A/Pten double knockout (DKO) mice were generated and demonstrated that the deletion of MAO A delayed prostate tumor development in the Pten knockout mouse model of prostate adenocarcinoma ... Thus, MAO A inhibitor may alleviate immune suppression, increase the antitumor immune response and be used for cancer immunotherapy" - Note: Deprenyl is an old time anti-aging drug but it's a MOQ B inhibitor. I don't know of any MAO A inhibitors.
  • Metformin, Testosterone Replacement Linked to Reduced Cancer Risk - Medscape, 8/26/22 - "metformin and testosterone replacement therapy were independently and jointly associated with a reduced incidence of prostate cancer, with the greatest reduction with the combination of the two (joint odds ratio [OR],  0.44) ... The two drugs were also inversely associated with a high grade at prostate cancer diagnosis (joint OR, 0.36) and advanced cancer stage (joint OR, 0.47), after multivariate adjustment for factors including age, race/ethnicity, hypogonadism, hypertension, diabetes, insulin use, muscular wasting, and other factors ... Metformin and testosterone replacement therapy were also independently and in combination inversely associated with the incidence of colorectal cancers (joint OR, 0.47); however, the associations with higher grade and advanced stage were not consistent, the authors note" - Note: Good luck with that. Testosterone prescriptions are another one that's like getting a prescription for cocaine. Doctors seem locked in a previous era. See metformin at ReliableRX.
  • The association between dairy products consumption and prostate cancer risk: A systematic review and meta-analysis - Br J Nutr. 2022 Aug 10 - "We performed subgroup analyses stratified by dairy type, prostate cancer type, follow-up years, treatment era, collection times, adjustment for confounders, and geographic location. In the subgroup analysis stratified by prostate cancer type, the pooled RRs were 0.98 (95% CI: 0.94-1.03) in the advanced group, 1.10 (95% CI: 0.98-1.24) in the non-advanced group and 0.92 (95% CI: 0.84-1.00) in the fatal group. In dose-response analysis, a positive association for the risk of prostate cancer was observed for total dairy products 400 g/d (RR: 1.02; 95% CI: 1.00, 1.03), total milk 200 g/d (RR: 1.02; 95% CI: 1.01, 1.03), cheese 40 g/d (RR: 1.01; 95% CI: 1.00, 1.03), and butter 50 g/d (RR: 1.03; 95% CI: 1.01, 1.05).

  • Quercetin in Tonglong Qibi decoction ameliorates testosterone-induced benign prostatic hyperplasia in rats by regulating Nrf2 signalling pathways and oxidative stress - Andrologia 2022 Jun 20 - "Benign prostatic hyperplasia (BPH) is a common urological disease in older males. Existing pharmacotherapy shows several side effects, and the exploration of new therapeutic strategies is of high significance. Tonglong Qibi (TQ) decoction was proved to ameliorate BPH, while the underlying mechanisms are still unclear. In the current study, we explored the anti-BPH effects of TQ in vivo and identified its main therapeutic component and the underlying mechanisms in vitro. We demonstrated that TQ mitigated BPH in rats and showed no toxicity to the liver and reproductive system. Network pharmacology identified quercetin as the main component in TQ treating BPH. Quercetin reduced proliferation, oxidative stress, and increased Nrf2 expression in hyperplastic prostate epithelial cells. These findings indicate that quercetin in TQ alleviates BPH via inhibiting oxidative stress and activating the Nrf2 signalling pathway" - See quercetin at Amazon.com.
  • Dairy foods, calcium intakes, and risk of incident prostate cancer in Adventist Health Study-2 - Am J Clin Nutr 2022 Jun 8 - "Men with higher intake of dairy foods, but not nondairy calcium, had a higher risk of prostate cancer compared with men having lower intakes.

  • Circulating free testosterone and risk of aggressive prostate cancer: prospective and Mendelian randomization analyses in international consortia - Int J Cancer 2022 May 17 - "In blood-based analyses there was no association with aggressive disease overall, but there was heterogeneity by age at blood collection (OR for men aged <60 years 1.14, CI=1.02-1.28; Phet =0.0003: inverse association for older ages). Associations for free testosterone were positive for overall prostate cancer (MR:1.20,1.08-1.34; blood-based:1.03,1.01-1.05) and early-onset prostate cancer (MR:1.37,1.09-1.73; blood-based:1.08,0.98-1.19). SHBG and total testosterone were inversely associated with overall prostate cancer in blood-based analyses, with null associations in MR analysis. Our results support free testosterone, rather than total testosterone, in the development of prostate cancer, including aggressive subgroups"
  • Adherence to a cholesterol-lowering diet and the risk of prostate cancer - Food Funct 2022 May 6 - "The score was derived from seven dietary indicators which have been reported to lower cholesterol levels: high intake of non-cellulosic polysaccharides (viscous fibres), monounsaturated fatty acids, legumes, seeds/corn oil; low intake of saturated fatty acids, dietary cholesterol, and glycaemic index. Odds ratios (ORs) and corresponding confidence intervals (CIs) were calculated through the unconditional logistic regression model. Although most of the dietary indicators alone were not significantly associated with reduced PCa risk, men who fulfilled 5 to 7 dietary indicators (187 cases and 281 controls) showed a 43% reduction in PCa risk compared to those with 0 to 2 indicators (OR: 0.57"
  • The relationship between the gut microbiota, benign prostatic hyperplasia, and erectile dysfunction - Int J Impot Res 2022 Apr 13 - "Microbiota is defined as the group of commensal microorganisms that inhabit a specific human body site. The composition of each individual's gastrointestinal microbiota is influenced by several factors such as age, diet, lifestyle, and drug intake, but an increasing number of studies have shown that the differences between a healthy microbiota and a dysbiotic one can be related to different diseases such as benign prostatic hyperplasia (BPH) and erectile dysfunction (ED) ... Gut microbiota modifications can influence prostate health indirectly by the activation of the immune system and the production of proinflammatory cytokines such as IL-17, IL-23, TNF-alpha, and IFN-gamma, which are able to promote an inflammatory state. Gut dysbiosis may lead to the onset of ED by the alteration of hormone levels and metabolic profiles, the modulation of stress/anxiety-mediated sexual dysfunction, the development of altered metabolic conditions such as obesity and diabetes mellitus, and the development of hypertension. In conclusion, much evidence suggests that the intestinal microbiota has an influence on various pathologies including BPH and ED" - See probiotic supplements at Amazon.com.
  • 5-alpha reductase inhibitors and prostate cancer mortality among men with regular access to screening and health care - Cancer Epidemiol Biomarkers Prev 2022 Mar 4 - "Men using 5-ARIs underwent more PSA testing, prostate exams and biopsies. Over 20 years of follow-up, 509 men developed lethal disease (metastases or prostate cancer death). Among men initially free from prostate cancer, 5-ARI use was not associated with developing lethal disease (HR 1.02, 0.71-1.46), but was associated with reduced rates of overall and localized disease (HR 0.71, 0.60-0.83). Among men diagnosed with prostate cancer, there was no association between 5-ARI use and cancer-specific (HR 0.78, 0.48-1.27) or overall survival (HR 0.88" - See saw palmetto at Amazon.com.
  • Hexanic Extract of Serenoa repens (Permixon ®): A Review in Symptomatic Benign Prostatic Hyperplasia - Drugs Aging 2022 Mar 3 - "The hexanic extract (HE) of Serenoa repens (Permixon®) is indicated for the symptomatic treatment of benign prostatic hyperplasia (BPH). The drug is the n-hexane lipidosterolic extract of the American dwarf palm tree (also known as saw palmetto). The anti-inflammatory activity of HE S. repens has been demonstrated in vitro, in vivo and in men with prostatic inflammation. In randomized clinical trials, the efficacy of HE S. repens was similar to that of an α-blocker in terms of improving voiding and storage symptoms, increasing urinary flow rate and reducing prostate volume in men with BPH. HE S. repens was also as effective as 5α-reductase inhibitors and/or α-blockers at improving lower urinary tract symptoms (LUTS) and quality of life (QOL) in real-world observational studies. HE S. repens was generally well tolerated, with a lesser impact on male sexual function compared with other available therapies. Thus, HE S. repens is a useful option for the treatment of symptomatic BPH" - See saw palmetto at Amazon.com.
  • δ-Tocotrienol is the most potent vitamin E form in inhibiting prostate cancer cell growth and inhibits prostate carcinogenesis in Ptenp-/- mice - Cancer Prev Res (Phila) 2022 Feb 10 - "Vitamin E compounds, consisting of α, β, γ, and δ forms of tocopherols and tocotrienols, display different cancer preventive activities in experimental models. Tocotrienols may have higher potential for clinical use due to their lower effective doses in laboratory studies ... We found that δ-tocotrienol (δT3) was the most effective form in inhibiting cell growth at equivalent doses. Because of this in vitro potency, δT3 was further studied using prostate specific Pten-/- (Ptenp-/-) mice. We found that 0.05% δT3 in diet reduced prostate adenocarcinoma multiplicity by 32.7%, featuring increased apoptosis and reduced cell proliferation. The inhibitory effect of 0.05% δT3 in diet was similar to that of 0.2% δ-tocopherol (δT) in diet reported previously. Our further study on the δT3-induced transcriptome changes indicated that δT3 inhibited genes in blood vessel development in the prostate of Ptenp-/- mice, which was confirmed by immunohistochemistry. Together, our results demonstrate that δT3 effectively inhibits the development of prostate adenocarcinoma in Ptenp-/- mice, which involves inhibition of proliferation and angiogenesis and promotion of apoptosis" - See delta vitamin E at Amazon.com.
  • Dietary pterostilbene for MTA1-targeted interception in high-risk premalignant prostate cancer - Cancer Prev Res (Phila) 2021 Oct 21 - "mice fed with a pterostilbene-supplemented diet exhibited more favorable histopathology with decreased severity and number of PIN foci accompanied by reduced proliferation, angiogenesis, and inflammation concomitant to reduction in MTA1 and MTA1-associated CyclinD1, Notch2, and oncogenic miR-34a and miR-22 levels" - See pterostilbene at Amazon.com and iHerb.
  • Induction of apoptosis in human hormone-refractory prostate cancer cell lines by using resveratrol in combination with AT-101 - Andrologia 2021 Oct 11 - "The aim of this study was to determine the appropriate doses of AT-101 and resveratrol combination in the in vitro hormone-refractory prostate cancer (PC) cell lines, in order to evaluate the cytotoxic and genotoxic effects of this combination on the proliferation of cancer cells, namely PC-3, DU-145 and LNCAP ... While the combined use of resveratrol and AT-101 increased the expression of markers in apoptotic cell pathways on cells, a decrease in the expression of anti-apoptotic markers was detected (p ˂ 0.05). Combined applications of these compounds showed an important synergism in the hormone-refractory PC cell lines, and it was determined that after the post-translational modification, they were significantly effective on the apoptotic pathway. These results have revealed that the combination of resveratrol and AT-101 holds great expectation as a new chemotherapeutic application in the treatment of human prostate cancer" - See resveratrol products at Amazon.com and resveratrol at iHerb.
  • Rutin inhibits androgen synthesis and metabolism in rat immature Leydig cells in vitro - Andrologia 2021 Aug 29 - "In the early stage of androgen-sensitive prostate cancer, cancer cells require androgens to grow.

  • Cordyceps militaris Fruit Body Extract Decreases Testosterone Catabolism and Testosterone-Stimulated Prostate Hypertrophy - Nutrients 2020 Dec 26 - "late-onset hypogonadism (LOH) ... The fruit bodies of fungi of the genus Cordyceps have been regarded as folk medicine or health food with tonic and antifatigue effects. The extract from the fruit body of Cordyceps militaris parasitizing Samia cynthia ricini (CM) was evaluated as a novel-candidate natural product for ameliorating male andropause symptoms. To explore the effects of CM on LOH and BPH, CM was applied to rat models and cultured testicular cells and prostate cells. The concentrations of androgens in the serum and culture media were determined by ELISA. Expression of steroidogenic enzymes and androgen-related genes was evaluated by qPCR, and prostatic cell proliferation was assessed with the cell-viability assay. CM maintained the serum levels of testosterone and DHT, but inhibited testosterone-induced prostate hypertrophy. CM also increased the secretion of testosterone and DHT by primary testicular cells, with no changes in the mRNA expression of steroidogenic enzymes, but decreased the growth of prostatic cell lines. Our data suggest that CM could improve both LOH and BPH in males." - See cordyceps at Amazon.com.
  • Combination of Curcumin and Metformin Inhibits Cell Growth and Induces Apoptosis without Affecting the Cell Cycle in LNCaP Prostate Cancer Cell Line - Nutr Cancer 2020 Jul 13 - "The viability of cells treated with curcumin, metformin, and their combination was significantly (P < 0.05) reduced with increasing the concentration and prolonging the treatment time. Meanwhile, the combination showed a synergistic effect within 48 h. In the curcumin treated group, the expression of Bcl-2 and hTERT genes diminished. In the metformin treated group, the expression of Bax and PUMA genes was enhanced while the expression of Bcl-2, hTERT, mTOR, and p53 genes declined. Although all treatments induced apoptosis, the combination of curcumin and metformin showed the maximum level of apoptosis, cytotoxicity, and expression of Bax gene.

  • Oxidative Stress in Prostate Cancer - Medscape, 9/17/13 - "increased production of reactive oxygen species (ROS) is linked to aging processes and to the etiopathogenesis of aging-related diseases, such as cancer, diabetes, atherosclerosis and degenerative diseases like Parkinson's and Alzheimer's. Excess ROS are deleterious to normal cells, while in cancer cells, they can lead to accelerated tumorigenesis ... Reactive oxygen species (ROS), also termed oxidants, are common by-products of the standard aerobic cellular metabolism, continuously formed in the cell and synchronously scavenged by an array of antioxidant mechanisms ... At the molecular level, ROS production takes place continuously at redox-active centers within enzymes or when ubiquinone (coenzyme Q10 (CoQ)), the essential electron carrier, accepts or donates electrons ... At the molecular level, ROS production takes place continuously at redox-active centers within enzymes or when ubiquinone (coenzyme Q10 (CoQ)), the essential electron carrier, accepts or donates electrons. Unique bioenergetic conditions are required to occur, such as high NADH-H+/NAD ratio or a high proton-motive force across the inner mitochondrial membrane (Δp) and concomitantly reduced CoQ pool (CoQH2), to accelerate ROS formation in the mitochondria ... Adiponectin, a hormone inversely associated with obesity, inhibits oxidative stress in human PC cells in a dose-dependent manner. Lower levels of adiponectin in obese individuals may result in higher levels of prostatic oxidative stress, which may explain the clinical association between obesity, hypoadiponectinemia and PC ... Several foods containing natural antioxidants, such as polyphenols and flavonoids, and other phytonutrients, such as vitamins and minerals, are proposed to facilitate ROS detoxification ... Several potential suggestions have been put forth to explain the results of the study, which were contrary to the original prevention hypothesis. (i) The high dose of vitamin E (400 IU), which was eight times higher than the 50 IU used in the ABTC study, may abolish the preventive effect or even contribute to the increased risk of PC demonstrated in the study.[82] (ii) Animal studies demonstrate cancer preventive activity of γ- and δ-tocopherols, as well as for the naturally occurring mixture of tocopherols, but not by α-tocopherol,[83] the source of vitamin E used in the SELECT trail. (iii) Different individuals may respond inconsistently to antioxidant treatment depending on specific, intrinsic genetic risk factors"

The risk reduction of death from other causes was initially the same but declined over time ... No reduction in death risk was seen for patients taking any other diabetes drug ... other diabetes drugs work by increasing the body's insulin production, metformin is an "insulin sensitizer" that works by making the body more sensitive to the insulin already produced ... Some research suggests that high insulin levels can influence cancer growth. Metformin, by not increasing the body's insulin production, may decrease cancer cells' growth, some experts say" - Note:  Metformin is another one that I take in low dose for anti-aging. - See metformin at The Antiaging Store.

  • A low dietary ratio of omega-6 to omega-3 Fatty acids may delay progression of prostate cancer - Nutr Cancer. 2013;65(4):556-62 - "High amounts of omega-6 fatty acids have been linked with increased prostate cancer risk, whereas omega-3 fatty acids have been shown to inhibit PCa growth. However, because omega-3 and omega-6 are both essential fatty acids and part of a complete diet, it is more relevant to determine the ideal ratio of the two that would allow patients to benefit from the therapeutic properties of omega-3 fatty acids. LNCaP prostate cancer cells were treated with dietary-based ratios of omega-6 to omega-3 fatty acids under hormone-deprivation conditions, and effects on various cellular processes were determined. A low omega-6 to omega-3 PUFA ratio can delay the progression of cells toward castration-resistance by suppressing pathways involved in prostate cancer progression, such as the Akt/mTOR/NFκB axis. It also suppresses the expression of cyclin D1, and activation of caspase-3 and annexin V staining shows induction of proapoptotic events. Taken together, our data demonstrates that maintaining a low omega-6 to omega-3 fatty acids ratio can enhance efficacy of hormone ablation therapy" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.
  • Soy and tomato may be effective in preventing prostate cancer - Science Daily, 5/8/13 - "From the time they were 4 to 18 weeks old, the animals were fed one of four diets: (1) 10 percent whole tomato powder; (2) 2 percent soy germ; (3) tomato powder plus soy germ; and (4) a control group that ate neither tomato nor soy ... Eating tomato, soy, and the combination all significantly reduced prostate cancer incidence. But the combination gave us the best results. Only 45 percent of mice fed both foods developed the disease compared to 61 percent in the tomato group, and 66 percent in the soy group ... The results of the mouse study suggest that three to four servings of tomato products per week and one to two servings of soy foods daily could protect against prostate cancer" - See Jarrow Lyco-Sorb (contains Lyco-O-Mato) at Amazon.com.

In this context the fact that the substance is well tolerated is very important, because one can safely recommend it to individuals who have an increased tumor risk" - See curcumin products at Amazon.com.
  • Tadalafil : In the Treatment of Signs and Symptoms of Benign Prostatic Hyperplasia with or without Erectile Dysfunction - Drugs Aging. 2012 Sep;29(9):771-81 - "Once-daily tadalafil 5 mg was effective in treating the signs and symptoms of benign prostatic hyperplasia (BPH). In phase III trials in men with BPH, the mean change from baseline to week 12 in the total International Prostate Symptom Score (IPSS; primary endpoint) was significantly greater in those treated with once-daily tadalafil 5 mg than with placebo. Improvements in total IPSS that occurred over the initial 12 weeks of tadalafil treatment were maintained with continued treatment over a 1-year period in an open-label extension study. Moreover, tadalafil was effective in treating both erectile dysfunction (ED) and the signs and symptoms of BPH in a phase III trial that specifically enrolled men with both indications. Both the International Index of Erectile Function-Erectile Function domain score and the total IPSS (co-primary endpoints) were significantly improved from baseline to week 12 after treatment with once-daily tadalafil 5 mg compared with placebo" - See tadalafil at OffshoreRx1.com.

  • Zyflamend, a Combination of Herbal Extracts, Attenuates Tumor Growth in Murine Xenograft Models of Prostate Cancer - Nutr Cancer. 2012 Jun 4 - "Prostate cancer (PrC) is the second deadliest cancer of males in the United States Hormone deprivation therapy (HDT), a common therapy for advanced forms of the disease, results in tumor regression; unfortunately, tumors inevitably become castrate-resistant ... Zyflamend® is a combination of extracts from multiple herbs, each with reported anticancer properties. Zyflamend can inhibit growth of various PrC cell lines, but no studies have investigated its potential use in vivo using a model of castrate-resistant PrC. In this study, oral doses of Zyflamend at human equivalent doses inhibited androgen-dependent and castrate-resistant tumor growth in a mouse model that mimics advanced stages of the disease, and reduced the expression of a number of biomarkers linked to PrC progression including pAKT, prostate specific antigen, histone deacetylases, and androgen receptor. In summary, this is the first article to report that Zyflamend, when provided at human equivalent doses, can potentiate the effects of hormone deprivation on tumor regression and growth inhibition of androgen-dependent and castrate-resistant PrC tumors in vivo" - See Zyflamend at Amazon.com.

  • B-DIM Impairs Radiation-Induced Survival Pathways Independently of Androgen Receptor Expression and Augments Radiation Efficacy in Prostate Cancer - Cancer Lett. 2011 Dec 9 - "Increased consumption of cruciferous vegetables is associated with decreased risk in prostate cancer (PCa). The active compound in cruciferous vegetables appears to be the self dimerized product [3,3'-diindolylmethane (DIM)] of indole-3-carbinol (I3C). Nutritional grade B-DIM (absorption-enhanced) has proven safe in a Phase I trial in PCa ... B-DIM inhibited cell growth in a dose-dependent manner in both PC-3 (AR-) and C4-2B (AR+) cell lines. B-DIM was effective at increasing radiation-induced cell killing in both cell lines, independently of AR expression. B-DIM inhibited NF-κB and HIF-1α DNA activities and blocked radiation-induced activation of these transcription factors in both PC-3 and C4-2B cells. In C4-2B (AR+) cells, AR expression and nuclear localization were significantly increased by radiation. However, B-DIM abrogated the radiation-induced AR increased expression and trafficking to the nucleus, which was consistent with decreased PSA secretion. In vivo, treatment of PC-3 prostate tumors in nude mice with B-DIM and radiation resulted in significant primary tumor growth inhibition and control of metastasis to para-aortic lymph nodes. These studies demonstrate that B-DIM augments radiation-induced cell killing and tumor growth inhibition. B-DIM impairs critical survival signaling pathways activated by radiation, leading to enhanced cell killing. These novel observations suggest that B-DIM could be used as a safe compound to enhance the efficacy of radiotherapy for castrate-resistant PCa" - See diindolylmethane at Amazon.com.
  • You are what you eat: Low fat diet with fish oil slows growth of human prostate cancer cells, study suggests - Science Daily, 10/25/11 - "Men who ate a low-fat diet with fish oil supplements for four to six weeks before having their prostate removed had slower cancer-cell growth in their prostate tissue than men who ate a traditional, high-fat Western diet ... The short-term study also found that blood obtained from patients after the low-fat, fish oil diet slowed the growth of prostate cancer cells in a test tube, while blood from men on the Western diet did not slow cancer growth ... Preclinical studies suggest that lowering dietary omega-6 fatty acids from corn oil and increasing omega-3 fatty acids from fish oil decreases the risk of prostate cancer development and progression," the study states. "We found this diet intervention resulted in a decrease in omega-6 vs. omega-3 fatty acid ratios in benign and malignant prostate tissue and a decrease in malignant cell proliferation" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

  • Calcium intake and prostate cancer among African Americans: Effect modification by vitamin D receptor calcium absorption genotype - J Bone Miner Res. 2011 Sep 1 - "Compared to men in the lowest quartile of calcium intake, men in the highest quartile had an approximately two-fold increased risk of localized and advanced prostate cancer (odds ratio [OR]= 2.20, 95% confidence interval [CI]= 1.40, 3.46), with a significant dose-response. Poor absorbers of calcium (VDR Cdx2 GG genotype) had a significantly lower risk of advanced prostate cancer (OR= 0.41, 95% CI = 0.19, 0.90). The gene-calcium interaction was statistically significant (p = 0.03). Among men with calcium intake below the median (680 mg/day), carriers of the G allele had an approximately 50% decreased risk compared to men with the AA genotype. These findings suggest a link between prostate cancer risk and high intestinal absorption of calcium"
  • Associations of serum vitamin A and carotenoid levels with markers of prostate cancer detection among US men - Cancer Causes Control. 2011 Jul 29 - "Associations of serum vitamin A and carotenoid levels with markers of prostate cancer detection were evaluated among 3,927 US men, 40-85 years of age, who participated in the 2001-2006 National Health and Nutrition Examination Surveys. Five recommended definitions of prostate cancer detection were adopted using total and free prostate-specific antigen (tPSA and fPSA) laboratory measurements. Men were identified as high risk based on alternative cutoffs, namely tPSA > 10 ng/ml, tPSA > 4 ng/ml, tPSA > 2.5 ng/ml, %fPSA < 25%, and %fPSA < 15%. %fPSA was defined as (fPSA÷tPSA)× 100%. Serum levels of vitamin A (retinol and retinyl esters) and carotenoids (α-carotene, β-carotene, β-cryptoxanthin, lutein + zeaxanthin, lycopene) were defined as quartiles and examined as risk/protective factors for PSA biomarkers. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using binary logistic models. After adjustment for known demographic, socioeconomic, and lifestyle confounders, high serum levels of retinyl esters (tPSA > 10 ng/ml: Q4 vs. Q1 → OR = 0.38, 95% CI: 0.14-1.00) and α-carotene (%fPSA < 15%: Q4 vs. Q1 → OR = 0.49, 95% CI: 0.32-0.76) were associated with a lower odds, whereas high serum level of lycopene (tPSA > 2.5 ng/ml: Q4 vs. Q1 → OR = 1.49, 95% CI: 1.01-2.14) was associated with a greater odds of prostate cancer detection. Apart from the three significant associations observed, no other exposure-outcome association was significant. Monitoring specific antioxidant levels may be helpful in the early detection of prostate cancer"
  • Impact of Consumption of Vegetable, Fruit, Grain, and High Glycemic Index Foods on Aggressive Prostate Cancer Risk - Nutr Cancer. 2011 Jul 20 - "Here we further investigate such potential relationships with a case-control study of 982 men (470 more aggressive prostate cancer cases and 512 control subjects). Comparing the highest to lowest quartiles of intake, we found that increasing intakes of leafy vegetables were inversely associated with risk of aggressive prostate cancer [adjusted odds ratio (OR) = 0.66, 95% CI: 0.46, 0.96; P trend = 0.02], as was higher consumption of high carotenoid vegetables (OR = 0.71, 95% CI: 0.48, 1.04; P trend = 0.04). Conversely, increased consumption of high glycemic index foods were positively associated with risk of aggressive disease (OR = 1.64, 95% CI: 1.05, 2.57; P trend = 0.02). These results were driven by a number of specific foods within the food groups. Our findings support the hypothesis that diets high in vegetables and low in high glycemic index foods decrease risk of aggressive prostate cancer"

  • Androgen-independent Effects of Serenoa repens Extract (Prostasan®) on Prostatic Epithelial Cell Proliferation and Inflammation - Phytother Res. 2011 Jun 8 - "Prostasan® inhibited epidermal growth factor (EGF) and lipopolysaccharide (LPS) induced proliferation of the prostatic epithelial, androgen independent cell line PC-3. At effective concentrations of 50 µg/mL, Prostasan® partly displaced EGF from EGF receptor (EGFR) but fully blocked EGF-induced cell proliferation of PC-3 cells. Similarly, Prostasan® inhibited LPS-induced proliferation of PC-3 cells without affecting LPS activation of the NFĸB pathway via toll-like receptor-4 (TLR-4). Additionally, Prostasan® reduced the constitutive secretion of monocyte chemotactic protein-1 (MCP-1), the LPS-induced secretion of IL-12 and inhibited MCP-1 and granulocyte-macrophage colony-stimulating factor (GM-CSF) production in the presence of LPS on PC-3 cells. Taken together, our results suggest that S. repens extracts, in addition to other reported effects on BPH development and prostatitis, inhibits EGF-dependent growth and proinflammatory responses of the prostate epithelial cells" - See Prostasan at Amazon.com.
  • Omega-3 Fatty Acid Inhibition of Prostate Cancer Progression to Hormone Independence Is Associated With Suppression of mTOR Signaling and Androgen Receptor Expression - Nutr Cancer. 2011 Jun 10:1-7 - "We used an in vitro model of androgen ablation to determine the effect of treatment with omega-3 fatty acids on the progression to an androgen-independent state. The omega-3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) were able to prevent progression of LNCaP cells while the omega-6 fatty acid arachidonic acid (AA) actually promoted cell growth under conditions of hormone depletion. These results correlated with a decrease in the expression of the androgen receptor as well as suppression of the Akt/mTOR signaling pathway. Connecting the mechanisms by which omega-3 fatty acids affect phenotypic outcome is important for effective exploitation of these nutrient agents as a therapeutic approach" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

  • Coffee Consumption and Prostate Cancer Risk and Progression in the Health Professionals Follow-up Study - J Natl Cancer Inst. 2011 May 17 - "Coffee contains many biologically active compounds, including caffeine and phenolic acids, that have potent antioxidant activity and can affect glucose metabolism and sex hormone levels ... The average intake of coffee in 1986 was 1.9 cups per day. Men who consumed six or more cups per day had a lower adjusted relative risk for overall prostate cancer compared with nondrinkers (RR = 0.82, 95% confidence interval [CI] = 0.68 to 0.98, P(trend) = .10). The association was stronger for lethal prostate cancer (consumers of more than six cups of coffee per day: RR = 0.40, 95% CI = 0.22 to 0.75, P(trend) = .03). Coffee consumption was not associated with the risk of nonadvanced or low-grade cancers and was only weakly inversely associated with high-grade cancer. The inverse association with lethal cancer was similar for regular and decaffeinated coffee (each one cup per day increment: RR = 0.94, 95% CI = 0.88 to 1.01, P = .08 for regular coffee and RR = 0.91, 95% CI = 0.83 to 1.00, P = .05 for decaffeinated coffee). The age-adjusted incidence rates for men who had the highest (≥6 cups per day) and lowest (no coffee) coffee consumption were 425 and 519 total prostate cancers, respectively, per 100 000 person-years and 34 and 79 lethal prostate cancers, respectively, per 100 000 person-years"

  • Thiazolidenediones induce tumour-cell apoptosis through the Akt-GSK3β pathway - J Clin Pharm Ther. 2011 Mar 16 - "Prostate cancer is a major health threat for men. Thiazolidenediones (TZDs) are synthetic ligands of the peroxisome proliferator-activated receptor γ (PPARγ), and previous studies have shown that TZDs induce apoptosis of prostate cancer cells independently of PPARγ activation. However, the exact mechanism of these effects remains unknown ... The apoptosis-inducing effect of TZDs on prostate cancer cells involves the inhibition of Akt phosphorylation. Furthermore, TZDs induce inactivation of GSK3β, a multifunctional kinase that mediates essential events promoting prostate cancer development and acquisition of androgen independence. In addition, the GSK3β inhibitor lithium chloride sensitizes prostate cancer cells to TZDs cytotoxicity. What is new and Conclusion:  Our data suggest that modulation of Akt-GSK3β pathway is involved in the cell death pathway engaged by TZDs in prostate cancer cells. This reveals another possible mechanism of TZDs on apoptosis in prostate cancer. Inhibition of the Akt-GSK3β cascade may be a useful approach in prostate cancer" - Got that because I'm going to give a test on it in next weeks newsletter.  The point is that TZDs such as pioglitazone may help prevent or slow prostate cancer.  See Pioglitazone at OffshoreRx1.com.

  • Chemopreventative Potential of the Cruciferous Vegetable Constituent Phenethyl Isothiocyanate in a Mouse Model of Prostate Cancer - J Natl Cancer Inst. 2011 Feb 17 - "This study was undertaken to determine the chemopreventative efficacy of phenethyl isothiocyanate (PEITC), a bioactive constituent of many edible cruciferous vegetables, in a mouse model of prostate cancer, and to identify potential biomarker(s) associated with PEITC response ... Administration of PEITC (3 μmol/g diet) decreased incidence (PEITC diet vs control diet, mean = 21.65 vs 57.58%, difference = -35.93%, 95% confidence interval = -45.48% to -13.10%, P = .04) as well as burden (affected area) (PEITC diet vs control diet, mean = 18.53% vs 45.01%, difference = -26.48%, 95% confidence interval = -49.78% to -3.19%, P = .02) of poorly differentiated tumors in the dorsolateral prostate of transgenic mice compared with control mice, with no toxic effects. PEITC-mediated inhibition of prostate carcinogenesis was associated with induction of autophagy and overexpression of E-cadherin in the dorsolateral prostate. However, PEITC treatment was not associated with a decrease in cellular proliferation, apoptosis induction, or inhibition of neoangiogenesis. Plasma proteomics revealed distinct changes in the expression of several proteins (eg, suppression of clusterin protein) in the PEITC-treated mice compared with control mice. Conclusions In this transgenic model, dietary PEITC suppressed prostate cancer progression by induction of autophagic cell death. Potential biomarkers to assess the response to PEITC treatment in plasma were identified" - See cruciferous supplements at Amazon.com.

  • Soy isoflavones in conjunction with radiation therapy in patients with prostate cancer - Nutr Cancer. 2010 Oct;62(7):996-1000 - "Soy isoflavones sensitize prostate cancer cells to radiation therapy by inhibiting cell survival pathways activated by radiation. At the same time, soy isoflavones have significant antioxidant and anti-inflammatory activity, which may help prevent the side effects of radiation ... Adverse effects of radiation therapy on bladder, bowel, and sexual function were assessed by a self-administered quality of life questionnaire at 3 and 6 mo. Only 26 and 27 patients returned completed questionnaires at 3 and 6 mo, respectively. At each time point, urinary, bowel, and sexual adverse symptoms induced by radiation therapy were decreased in the soy isoflavone group compared to placebo group. At 3 mo, soy-treated patients had less urinary incontinence, less urgency, and better erectile function as compared to the placebo group. At 6 mo, the symptoms in soy-treated patients were further improved as compared to the placebo group. These patients had less dripping/leakage of urine (7.7% in Group 1 vs. 28.4% in Group 2), less rectal cramping/diarrhea (7.7% vs. 21.4%), and less pain with bowel movements (0% vs. 14.8%) than placebo-treated patients. There was also a higher overall ability to have erections (77% vs. 57.1%). The results suggest that soy isoflavones taken in conjunction with radiation therapy could reduce the urinary, intestinal, and sexual adverse effects in patients with prostate cancer" - See soy isoflavones at Amazon.com.

An increased risk was also observed with increasing intake of sucrose and disaccharides. In contrast, men in the highest quartile of cholesterol intake were at lower risk of PCa. No association was found with intake of total proteins, total fat, monounsaturated fats, polyunsaturated fats, monosaccharides, and total carbohydrates. The findings provide evidence that a diet low in trans fat could reduce PCa risk"
  • Mixed Tocotrienols Inhibit Prostate Carcinogenesis in TRAMP Mice - Nutr Cancer. 2010 Aug;62(6):789-94 - "mixed-tocotrienol-fed groups had a lower incidence of tumor formation along with a significant reduction in the average wet weight of genitourinary apparatus. Furthermore, mixed tocotrienols significantly reduced the levels of high-grade neoplastic lesions as compared to the positive controls. This decrease in levels of high-grade neoplastic lesions was found to be associated with increased expression of proapoptotic proteins BAD (Bcl(2) antagonist of cell death) and cleaved caspase-3 and cell cycle regulatory proteins cyclin dependent kinase inhibitors p21 and p27. In contrast, the expression of cyclins A and E were found to be decreased in mixed-tocotrienol groups. Taken together, our results show that by modulating cell cycle regulatory proteins and increasing expression of proapoptotic proteins, mixed tocotrienols suppress prostate tumorigenesis in the TRAMP mice" - See Jarrow FamilE (contains all eight members of the vitamin E family, includes Tocomin) at Amazon.com.

  • Gamma-tocotrienol as an effective agent in targeting prostate cancer stem cell-like population - Int J Cancer. 2010 Jul 8 - "Emerging evidence supports that prostate cancer originates from a rare sub-population of cells, namely prostate cancer stem cells (CSCs). Conventional therapies for prostate cancer are believed to mainly target the majority of differentiated tumor cells but spare CSCs, which may account for the subsequent disease relapse after treatment. Therefore, successful elimination of CSCs may be an effective strategy to achieve complete remission from this disease. Gamma-tocotrienols (gamma-T3) is one of the vitamin-E constituents which have been shown to have anticancer effects against a wide-range of human cancers. Recently, we have reported that gamma-T3 treatment not only inhibits prostate cancer cell invasion but also sensitizes the cells to docetaxel-induced apoptosis, suggesting that gamma-T3 may be an effective therapeutic agent against advanced stage prostate cancer. Here, we demonstrate for the first time that gamma-T3 can down-regulate the expression of prostate CSC markers (CD133/CD44) in androgen independent (AI) prostate cancer cell lines (PC-3 & DU145), as evident from western blotting analysis. Meanwhile, the spheroid formation ability of the prostate cancer cells was significantly hampered by gamma-T3 treatment. In addition, pre-treatment of PC-3 cells with gamma-T3 was found to suppress tumor initiation ability of the cells. More importantly, while CD133-enriched PC-3 cells were highly resistant to docetaxel treatment, these cells were as sensitive to gamma-T3 treatment as the CD133-depleted population. Our data suggest that gamma-T3 may be an effective agent in targeting prostate CSCs, which may account for its anticancer and chemosensitizing effects reported in previous studies" - See Jarrow FamilE (contains all eight members of the vitamin E family, includes Tocomin) at Amazon.com.

  • Effects of phenylethyl isothiocyanate and its metabolite on cell-cycle arrest and apoptosis in LNCaP human prostate cancer cells - Int J Food Sci Nutr. 2010 May;11(7):324-36 - "Cruciferous vegetable consumption is associated with decreased risk of several cancers, including prostate cancer. Gluconasturtiin, one of the predominant glucosinolates in cruciferous vegetables, is hydrolyzed to yield phenylethyl isothiocyanate (PEITC). PEITC absorption and metabolism in humans involves glutathione conjugation followed by conversion via the mercapturic acid pathway to an N-acetylcysteine (NAC) conjugate that is excreted in the urine. We observed an inhibitory effect of PEITC and its metabolite, NAC-PEITC, on cancer cell proliferation, cell-cycle progression, and apoptosis in LNCaP human prostate cancer cells. PEITC and NAC-PEITC suppressed LNCaP cell proliferation in a dose-dependent manner, and exposure to 5 microM PEITC or NAC-PEITC reduced cell proliferation by 25% and 30%, respectively. Cell-cycle analysis revealed that cells treated with 5 microM PEITC or NAC-PEITC arrested at the G(2)/M phase. In addition, the percentage of cells in the S phase decreased from 46% to 25% following 48 h of incubation with PEITC or NAC-PEITC. The G(2)/M-phase cell-cycle arrest of LNCaP cells grown in the presence of PEITC or NAC-PEITC is correlated with the downregulation of Cdk1 and cyclin B(1) protein expression. Apoptosis was observed at the later stages of 24-h and 48-h treatments with 5 microM PEITC and NAC-PEITC. In conclusion, PEITC and NAC-PEITC are potential chemopreventive/chemotherapeutic agents against LNCaP human prostate cancer cells"
  • Lycopene effects contributing to prostate health - Nutr Cancer. 2009 Nov;61(6):775-83 - "Epidemiological evidence links lycopene consumption with decreased prostate cancer risk ... Lycopene modulates several of the aforementioned pathways, providing a promising rationale for prostate cancer risk reduction by lycopene: In many experimental setups, lycopene reduced inflammatory signals, prevented oxidative DNA damage, modulated the expression or activity of IGF axis members, of Wnt/beta-catenin and androgen signalling, and enhanced gap junctional communication. Lycopene's influence on these pathways likely contributes to the observed cell growth inhibition and apoptosis induction by lycopene. A substantial part of the lycopene effects can be explained by its antioxidant action, but other mechanisms might also be involved" - See lycopene at Amazon.com.
  • Fats of any kind may boost prostate cancer risk: Study - Nutra USA, 1/29/10 - "Last year, a study from Harvard reported that increased intakes of trans-fatty acids may increase the risk of non-aggressive prostate tumors by about 100 per cent ... the highest blood levels of trans oleic acid and linoleic acids (18:1n-9t and 18:2t) were associated with a 116 and 97 per cent increase in the risk of non-aggressive prostate tumors, respectively, compared to the lowest levels.

  • Intakes of meat, fish, poultry, and eggs and risk of prostate cancer progression - Am J Clin Nutr. 2009 Dec 30 - "Intakes of processed and unprocessed red meat, fish, total poultry, and skinless poultry were not associated with prostate cancer recurrence or progression. Greater consumption of eggs and poultry with skin was associated with 2-fold increases in risk in a comparison of extreme quantiles: eggs [hazard ratio (HR): 2.02; 95% CI: 1.10, 3.72; P for trend = 0.05] and poultry with skin (HR: 2.26, 95% CI: 1.36, 3.76; P for trend = 0.003). An interaction was observed between prognostic risk at diagnosis and poultry. Men with high prognostic risk and a high poultry intake had a 4-fold increased risk of recurrence or progression compared with men with low/intermediate prognostic risk and a low poultry intake (P for interaction = 0.003). CONCLUSIONS: Our results suggest that the postdiagnostic consumption of processed or unprocessed red meat, fish, or skinless poultry is not associated with prostate cancer recurrence or progression, whereas consumption of eggs and poultry with skin may increase the risk"

  • Prostate cancer incidence in men with Prostate-Specific Antigen (PSA) below 3 ng/mL: The Finnish Randomized Study of Screening for Prostate Cancer (FinRSPC) - Int J Cancer 2022 Sep 2 - "Prostate-specific antigen (PSA)-based screening for prostate cancer (PCa) can reduce PCa mortality, but also involves over-detection of low-risk disease with potential adverse effects. We evaluated PCa incidence among men with PSA below 3 ng/mL and no PCa diagnosis at the first screening round of the Finnish Randomized Study of Screening for PCa. Follow-up started at the first screening attendance and ended at PCa diagnosis, emigration, death, or the common closing date (December 2016), whichever came first. Cox regression analysis was used to estimate hazard ratios and their confidence intervals (CI). Among men with PSA <3 ng/mL, cumulative PCa incidence was 9.1% after 17.6 years median follow-up. Cumulative incidence was 3.6% among men with baseline PSA 0-0.99 ng/mL, 11.5% in those with PSA 1.0-1.99 ng/mL and 25.7% among men with PSA 2-2.99 ng/mL (hazard ratio 9.0, 95% CI: 7.9-10.2 for the latter). The differences by PSA level were most striking for low-risk disease based on Gleason score and EAU risk group. PSA values <1 ng/mL indicate a very low 20-year risk, while at PSA 2-2.99 ng/mL risks are materially higher, with 4-5 -fold risk for aggressive disease. Using risk-stratification and appropriate re-screening intervals will reduce screening intensity and over-detection. Using cumulative incidence of clinically significant PCa (csPCa) as the criterion, re-screening intervals could range from approximately three years for men with initial PSA 2-2.99 ng/mL, six years for men with PSA 1-1.99 ng/mL to 10 years for men with PSA <1 ng/mL"

If I'm performing a biopsy on a smaller prostate, I'm more likely to hit that cancer than if I am sticking into a larger prostate. This drug wasn't causing more prostate cancer. It's causing more prostate cancer to be diagnosed" - [Abstract]
  • Ramelteon With an alpha 1-Blocker Decreases Nocturia in BPH - Medscape, 7/31/13 - "Ramelteon at 8 mg once daily for one month was added to the α1-blocker. A self-administered questionnaire including the International Prostate Symptom Score (IPSS), quality of life (QoL) index, Overactive Bladder Symptom Score (OABSS), and Nocturia Quality-of-Life Questionnaire (N-QOL) were assessed before and one month after starting ramelteon ... The mean score on IPSS question 7 (nocturia) decreased significantly from 2.88 before starting ramelteon to 2.41 one month after starting the medication (P = 0.03). The mean total OABSS decreased significantly from 6.31 to 5.38 (P = 0.03), and the mean for OABSS question 2 (nighttime frequency of nocturia) also significantly decreased from 2.63 to 2.13 (P = 0.01). The mean total N-QOL score did not change significantly" - Yeah but maybe it was just the deeper sleep that was responsible for less trips to the bathroom.

  • Three PSA Tests Over Lifetime Sufficient for Many Men - Medscape, 4/18/13 - "just 3 PSA tests over the course of a lifetime is sufficient for many men ... This premise comes from a team led by Andrew Vickers, PhD, from the Memorial Sloan-Kettering Cancer Center in New York City ... The best age for this initial PSA test is around 45 years, unless there is a strong family history of prostate cancer. Age 40 might be too early, and age 50 might be too late to identify a man's risk of developing an aggressive cancer ... Men who were found to have a PSA level below 1 ug/L on the initial test would be advised to return for screening in their early 50s and again at age 60. At the age of 60, men who still had a PSA level below 1 ug/L would be exempt from further screening"

  • The efficacy and safety of alpha-1 blockers for benign prostatic hyperplasia: an overview of 15 systematic reviews - Curr Med Res Opin. 2013 Jan 16 - "Doxazosin could significantly reduce urinary symptom scores compared with tamsulosin (MD -1.60, 95%CI -1.80--1.40) and alfuzosin (MD1.7, 95%CI 0.76-1.64). Indirect evidence suggested that the urinary symptom score and PUF at end point in men treated with naftopidil were similar to those treated with other α1-blockers. α1-blockers generally lead to more adverse effects compared with placebo, and those caused by terazosin were more frequent than others. Conclusions: α1-blockers are more effective than placebo for BPH, doxazosin and tamsulosin seem to be more effective than other α1-blockers. The adverse effects caused by α1-blockers are generally mild and well tolerated"

  • Pan-fried meat increases risk of prostate cancer, new study finds - Science Daily, 8/16/12 - "the risk of prostate cancer may be a result of potent chemical carcinogens formed when meats are cooked at high temperatures ... Researchers examined pooled data from nearly 2,000 men who participated in the California Collaborative Prostate Cancer Study ... men who ate more than 1.5 servings of pan-fried red meat per week increased their risk of advanced prostate cancer by 30 percent ... men who ate more than 2.5 servings of red meat cooked at high temperatures were 40 percent more likely to have advanced prostate cancer ... When considering specific types of red meats, hamburgers -- but not steak -- were linked to an increased risk of prostate cancer, especially among Hispanic men. "We speculate that these findings are a result of different levels of carcinogen accumulation found in hamburgers, given that they can attain higher internal and external temperatures faster than steak," ... pan-frying, regardless of meat type, consistently led to an increased risk of prostate cancer"
  • Study: PSA Testing Cuts Worst Metastatic Prostate Cancers - WebMD, 7/30/12 - "So should men get regular PSA tests? ...

  • Men with prostate cancer more likely to die from other causes - Science Daily, 7/26/12 - "Men diagnosed with prostate cancer are less likely to die from the disease than from largely preventable conditions such as heart disease ... The researchers examined causes of death among prostate cancer cases recorded in the U.S. Surveillance, Epidemiology, and End Results Program (over 490,000 men from 1973 to 2008) and the nationwide Swedish Cancer and Cause of Death registries (over 210,000 men from 1961 to 2008) ... during the study period, prostate cancer accounted for 52% of all reported deaths in Sweden and 30% of reported deaths in the United States among men with prostate cancer; however, only 35% of Swedish men and 16% of U.S. men diagnosed with prostate cancer died from this disease. In both populations, the risk of prostate cancer-specific death declined, while the risk of death from heart disease and non-prostate cancer remained constant. The five-year cumulative incidence of death from prostate cancer was 29% in Sweden and 11% in the United States ... lifestyle changes such as losing weight, increasing physical activity, and quitting smoking, may indeed have a greater impact on patients' survival than the treatment they receive for their prostate cancer"
  • Greater Percent-free Testosterone Is Associated With High-grade Prostate Cancer in Men Undergoing Prostate Biopsy - Urology. 2012 May 18 - "On multivariate analysis, testosterone (P ≥ .11) and free testosterone (P ≥ .45) were not significantly associated with low- or high-grade PCa. A greater %FT level significantly predicted high-grade PCa on both crude (P = .01) and multivariate (P = .02) analysis but not low-grade PCa (P ≥ .38). When examined in tertiles, men in the greatest %FT tertile had a significant twofold increased risk of high-grade PCa (odds ratio 2.04, 95% confidence interval 1.23-3.37, P = .005)"

The mean change from baseline in the total International Prostate Symptom Score was significantly greater with dutasteride plus tamsulosin than with dutasteride or tamsulosin alone after 2 years (primary endpoint) and 4 years of therapy. After 4 years' therapy in the CombAT trial, the time to first acute urinary retention or BPH-related surgery (primary endpoint) significantly favoured men with symptomatic BPH who were receiving dutasteride plus tamsulosin versus those receiving tamsulosin alone, with no significant difference between recipients of dutasteride plus tamsulosin and recipients of dutasteride alone. In the CombAT trial, health-related quality of life and treatment satisfaction were improved to a significantly greater extent with dutasteride plus tamsulosin than with dutasteride or tamsulosin alone. Combination therapy with oral dutasteride plus tamsulosin was generally well tolerated in patients with symptomatic BPH in the CombAT trial" - See dutasteride (Avodart) 30 x 0.5mg capsules at International Antiaging Systems.
  • Statin Use As a Moderator of Metformin Effect on Risk for Prostate Cancer Among Type 2 Diabetic Patients - Diabetes Care. 2012 Mar 28 - "Mean follow-up was ~5 years, and 7.5% had a PCa diagnosis. Statin use modified the effect of metformin on PCa incidence (P < 0.0001). Metformin was associated with a significantly reduced PCa incidence among patients on statins (HR 0.69 [95% CI 0.50-0.92]; 17 cases/533 metformin users vs. 135 cases/2,404 sulfonylureas users) and an increased PCa incidence among patients not on statins (HR 2.15 [1.83-2.52]; 22 cases/175 metformin users vs. 186 cases/1,930 sulfonylureas users). The HR of PCa incidence for those taking metformin and statins versus those taking neither medication was 0.32"

  • Study: PSA test doesn't save lives - USATODAY.com, 1/6/12 - "men randomly assigned to get PSA tests were 12% more likely to be diagnosed with prostate cancer, but no more likely to die. That suggests that 12% of men screened with the PSA were "overdiagnosed," or diagnosed with cancer that didn't need to be found, leading to unnecessary treatment ... the National Cancer Institute, which funded the $250 million trial ... it's possible that their study could have underestimated the benefits of screening. That's because only 85% of the men randomly assigned to get routine PSA screening actually did so. In the comparison arm of the trial, however, about half of the men not assigned to get a PSA decided to get one on their own" - Note:  So let's see, a quarter billion for the study and the answer is "we're not sure because many in the placebo group got the test anyway".
  • MRI Highly Accurate in Guiding Prostate Biopsy - Medscape, 12/5/11 - "In the post-prostate-specific antigen era, the diagnosis of prostate cancer is made using the 10-12 core transrectal US-guided biopsy procedure.

  • Prostate cancer may be tied to the Pill in water supply - MSNBC, 11/14/11 - "Several studies now have found an association between estrogen exposure and prostate cancer ... Birth control pills often contain a type of estrogen called ethinyloestradiol, which women taking the pills excrete in their urine. The hormone ends up in the water supply, or is taken up by plants or animals that use the water, and then passed up the food chain ... looked at prostate cancer mortality and contraceptive use in 88 countries for their analysis ... results of 'ecological' analyses like this one ... must be interpreted cautiously" - Note:  I mentioned several times about taking a quarter tablet of letrozole every third day.  It would seem like the amount of estrogen from drinking water would be minute compared to the amount of estrogen that is reduced by taking a small amount of letrozole. - See letrozole at OffshoreRX.
  • Task Force to Men: Don't Get PSA Test - WebMD, 10/7/11 - "Rising PSA levels are an early sign of prostate cancer, but the test gives a false cancer signal up to 80% of the time. Moreover, not all PSA-detected prostate cancers are dangerous ... The common perception that PSA-based early detection of prostate cancer saves lives is simply not supported by the scientific evidence ... The statement already is drawing harsh criticism, particularly from the American Urological Association ... It is our feeling that, when interpreted appropriately, the PSA test provides important information ... The task force is oversimplifying a complex series of [clinical trial] results ... I think there is real evidence of benefit for PSA screening. Death rates from prostate cancer have gone down … It is hard for me to believe all that is due to better treatment"
  • Tadalafil Approved for Benign Prostatic Hyperplasia - Medscape, 10/6/11 - "The US Food and Drug Administration (FDA) today approved tadalafil (Cialis, Eli Lilly), a phosphodiesterase-5 inhibitor, to also treat the signs and symptoms of benign prostatic hyperplasia (BPH) as well as a combination of BPH and erectile dysfunction (ED) when the conditions coincide ...

  • Genetics may explain why calcium increases risk for prostate cancer - Science Daily, 9/16/11 - "The team targeted a genetic allele that is more common in populations of African origin than in other populations and which is associated with regulating the absorption of calcium ... men who reported the highest intake of calcium were two times more likely to have localized and advanced prostate cancer than those who reported the lowest. Men with a genotype associated with poor calcium absorption were 59 percent less likely to have been diagnosed with advanced prostate cancer than men who genetically were the best absorbers of calcium. And, among men with calcium intake below the median, genetically poor absorbers had a 50 percent decreased risk of having advanced prostate cancer than the best absorbers"
  • Serum total and HDL cholesterol and risk of prostate cancer - Cancer Causes Control. 2011 Sep 14 - "After excluding the first 10 years of follow-up, men with higher serum total cholesterol were at increased risk of overall (≥240 vs. <200 mg/dl: HR = 1.22, 95% CI 1.03-1.44, p-trend = 0.01) and advanced (≥240 vs. <200 mg/dl: HR = 1.85, 95% CI 1.13-3.03, p-trend = 0.05) prostate cancer. Higher HDL cholesterol was suggestively associated with a decreased risk of prostate cancer regardless of stage or grade ... In this population of smokers, high serum total cholesterol was associated with higher risk of advanced prostate cancer, and high HDL cholesterol suggestively reduced the risk of prostate cancer overall. These results support previous studies and, indirectly, support the hypothesis that statins may reduce the risk of advanced prostate cancer by lowering cholesterol"

A major reason for preference of either drug was 'good efficacy'. Incidence of adverse effects was significantly lower with tamsulosin (3/91 patients; 3.3%) than with silodosin (25/88 patients; 28.4%). These findings indicate that tamsulosin is very effective for BPH, has few adverse effects and that patients want to continue to use it"

  • The effects of combination therapy with dutasteride plus tamsulosin on clinical outcomes in men with symptomatic BPH: 4-year post hoc analysis of European men in the CombAT study - Prostate Cancer Prostatic Dis. 2011 Apr 19 - "Patients were randomised to daily tamsulosin 0.4 mg, dutasteride 0.5 mg or both for 4 years ... Combination therapy significantly reduced the relative risk of AUR or BPH-related surgery compared with either monotherapy at 4 years, and also significantly reduced the risk of BPH clinical progression. Combination therapy also provided significantly greater symptom improvement than either monotherapy at 4 years. Safety and tolerability of dutasteride plus tamsulosin was consistent with previous experience of this combination and with the monotherapies. These data provide further evidence to support the use of long-term combination therapy (dutasteride plus tamsulosin) in men with moderate-to-severe lower urinary tract symptoms because of BPH and prostatic enlargement"

At five years, 11 percent of men taking statins saw their cancer return compared to 17 percent of patients not taking the medication. At eight years, 17 percent of men on statins had a relapse compared to 26 percent not taking the drug"
  • Apnea may be cause for awakening and voiding for those with enlarged prostates - Science Daily, 3/15/11 - "more than half (57.8 percent) of patients with enlarged prostates may in fact have the sleep disorder, and that the awakenings that patients ascribed to their need to urinate at night may be actually caused by their sleep disorders"
  • Change in PSA level does not predict prostate cancer - Science Daily, 2/24/11 - "Dr. Vickers and colleagues found no important association between PSA velocity and biopsy outcome after adjusting for risk factors such as age, race, and PSA levels. PSA alone was a much better predictor of biopsy outcome than PSA velocity ... We have previously published papers determining that PSA naturally varies from month to month and have urged men whose PSA suddenly rises to wait six weeks and repeat the test before agreeing to a needle biopsy. This new study in a large population of men provides even stronger evidence that using changes in PSA as a basis for recommendation for biopsy leads to many more unnecessary biopsies and does not help to find the more aggressive cancers that we want to find and treat"
  • Antagonists of growth hormone-releasing hormone (GHRH) reduce prostate size in experimental benign prostatic hyperplasia - Proc Natl Acad Sci U S A. 2011 Feb 14 - "Reduction of prostate weights was observed after 6 wk of treatment with GHRH antagonists: a 17.8% decrease with JMR-132 treatment; a 17.0% decline with MIA-313 treatment; and a 21.4% reduction with MIA-459 treatment (P < 0.05 for all). We quantified transcript levels of genes related to growth factors, inflammatory cytokines, and signal transduction and identified significant changes in the expression of more than 80 genes (P < 0.05). Significant reductions in protein levels of IL-1β, NF-κβ/p65, and cyclooxygenase-2 (COX-2) also were observed after treatment with a GHRH antagonist. We conclude that GHRH antagonists can lower prostate weight in experimental BPH. This reduction is caused by the direct inhibitory effects of GHRH antagonists exerted through prostatic GHRH receptors. This study sheds light on the mechanism of action of GHRH antagonists in BPH and suggests that GHRH antagonists should be considered for further development as therapy for BPH"
  • Comparison of Effects of Alpha Receptor Blockers on Endothelial Functions and Coagulation Parameters in Patients with Benign Prostatic Hyperplasia - Urology. 2011 Jan 20 - "When coagulation tests were evaluated, there were significant increases in bleeding and coagulation times in the groups using doxazosin and terazosin. Doxazosin and terazosin lowered arterial blood pressure significantly compared with other treatments. With regard to effects on endothelial function, there were significant differences in flow-mediated dilation rates of the brachial artery at 60 and 90 seconds before and during treatment in the alfuzosin and terazosin groups ... Alpha receptor blockers can decrease the risk of cardiovascular complications by both reducing platelet aggregation and protecting endothelial functions in patients with prostatic hyperplasia. The only drug with a favorable effect in all 4 areas of interest, including BPH symptoms, blood pressure, platelet aggregation, and endothelial functions, was terazosin"
  • Double Espresso vs Prostate Cancer - Medscape, 12/17/10 - "This wasn't a randomized trial. It was epidemiologic observational research. What they did was they gave people a questionnaire about their coffee drinking habits, and then they correlated that with hospital records on who got advanced prostate cancer and who didn't. Of course, there's a big problem with doing that type of research, which is that people who drink coffee may be different from people who don't drink coffee in all sorts of ways other than their caffeine consumption. Here's the number-one reason I don't actually believe the study. What the investigators reported was a 60% decrease in your risk for advanced prostate cancer if you drank coffee. Finasteride and dutasteride, these are drugs that we know in randomized trials are effective for prostate cancer, and we know that they have a mechanism of action that is pertinent to the prostate. Those 2 drugs reduce the risk for cancer by about 25%. Nothing is going to reduce the risk for advanced prostate cancer by 60%. I doubt if chemotherapy would. This is just a guess, little indication that the results of the study are due to bias ... There's another problem with these sorts of studies. Cancer takes a long time to develop. In fact, in the case of prostate cancer, we know that it takes 30 or more years between initiation of cancer and a clinical diagnosis"
  • PSA test better predicts cancer in men taking prostate-shrinking drug - Science Daily, 12/16/10 - "Dutasteride lowers PSA levels by about half within six months. But the researchers found that even a slight rise in PSA levels among men taking the drug was a stronger indicator of prostate cancer, particularly aggressive tumors that require early diagnosis and treatment, than rising PSA levels in men who took a placebo ... dutasteride reduced the risk of a prostate cancer diagnosis by 23 percent. Dutasteride appears to keep tumors small or shrink them to the point that they are less likely to be detected by a biopsy ... Over four years, PSA levels increased in 72 percent of men taking a placebo and only 29 percent of men taking dutasteride, the data show" - See dutasteride at OffshoreRx1.com.

  • Early PSA Predicts Prostate Cancer Risk -- But Then What? - Medscape, 12/1/10 - "The investigators went back and tested the blood samples of these men to see what their PSA [prostate-specific antigen] levels were up to 30 years before the diagnosis of prostate cancer was made. They found that if the PSA was > 0.63 ng/mL, they had a significant chance of developing cancer or advanced cancer many years in the future"
  • Ketoconazole May Help in Resistant Prostate Cancer - Medscape, 11/30/10 - "Based on prostate-specific antigen levels, two patients (5%) had a complete response, six (16%) had partial responses and 13 (35%) had stable disease" - Note: Ketoconazole is used off-label to reduce cortisol.  I don't know if there is a connection.

  • Finasteride May Be Helpful for Benign Prostatic Hypertrophy - Medscape, 10/8/10 - "Finasteride improves long-term urinary symptoms versus placebo, but is less effective than doxazosin," the study authors write. "Long-term combination therapy with alpha blockers (doxazosin, terazosin) improves symptoms significantly better than finasteride monotherapy. Finasteride + doxazosin improves symptoms equally — and clinically — to doxazosin alone. In comparison to doxazosin, finasteride + doxazosin appears to improve urinary symptoms only in men with medium (25 to < 40 mL) or large prostates (≥ 40 mL), but not in men with small prostates (25 mL)."

  • Blood test accurately predicts death from prostate cancer up to 25 years in advance - Science Daily, 9/15/10 - "90 percent of deaths occurred in men in the top 25 percent of PSA levels at age 60. The researchers concluded that men with a PSA level above 2 ng/ml at age 60 should be considered at increased risk of aggressive prostate cancer and should continue to be screened regularly ... Men with a PSA level below 1 ng / ml had a 0.2 percent chance of death from prostate cancer. The researchers concluded that men with PSA levels in this range, which is about half of all men, should be considered at low risk of prostate cancer death and may not need to be screened in the future. The study also indicated that some men found to be at low risk may actually have prostate cancer; however it is not likely to cause symptoms or shorten their life by the age of 85"
  • Early prostate cancer detection, screening: No benefit for men with low baseline PSA value, study finds - Science Daily, 9/13/10 - "The greatest benefits of early detection programs may be when men, aged 55-74 years, are diagnosed and treated when their serum PSA is in the range 4.0-9.9 ng/ml or 10.0-19.9 ng/ml. Furthermore, following research efforts that recommend more intensive PSA based screening by lowering the PSA cut-off may greatly increase the number of men that need additional investigations and treatment, whilst having little effect on the reduction of prostate cancer mortality"
  • Pioglitazone attenuates prostatic enlargement in diet-induced insulin-resistant rats by altering lipid distribution and hyperinsulinemia - Br J Pharmacol. 2010 Aug 19 - "Increased incidence of benign prostatic hyperplasia among insulin-resistant individuals suggest a role for hyperinsulinemia in prostatic enlargement ... High fat diet led to the accumulation of fat in non-adipose tissues, insulin resistance, compensatory hyperinsulinemia and prostatic enlargement in rats. Pioglitazone treatment altered fat distribution, improved insulin-sensitivity and normalized lipid and insulin level in rats on the high-fat diet. The improved metabolic parameters led to decreased cellular proliferation and increased apoptosis in the prostate gland. High-fat diet feeding and pioglitazone treatment did not change plasma testosterone levels. However, significant prostatic atrophy was observed in castrated, rats irrespective of dietary intervention" - Some doctors think I'm crazy but pioglitazone is one of the drugs I take for anti-aging.  See my Insulin and Aging page.

  • Reduction of Prostate-specific Antigen After Tamsulosin Treatment in Patients With Elevated Prostate-specific Antigen and Lower Urinary Tract Symptoms Associated With Low Incidence of Prostate Cancer at Biopsy - Urology. 2010 Jun 8 - "A total of 80 patients completed the present study. The mean patient age was 66.3 years, and the mean PSA level was 7.8 +/- 8.4 ng/mL at baseline and 7.1 +/- 9.1 ng/mL after treatment (P < .001). A total of 29 patients (36.25%) were diagnosed with prostate cancer from the biopsy findings. A significant increment in the PSA level was observed in patients with prostate cancer (6.7 versus 7.9 ng/mL; P = .002). A significant decrease in the PSA level was observed in patients with negative biopsy findings (6.9 versus 5.1 ng/mL, P = .000). Of the 38 patients with a decrease in the PSA level, 1 (2.6%) was diagnosed with prostate cancer and 37 (97.4%) with an benign prostatic hyperplasia/prostatitis. Of the 42 patients with no change in the PSA level, 28 (66.7%) had prostate cancer and 14 (33.3%) had negative findings. A change in PSA level after treatment gave a sensitivity of 96.6%, specificity of 72.5%, and diagnostic accuracy of 81% for prostate cancer. CONCLUSIONS: Treatment with tamsulosin seemed to reduce the PSA levels and identified patients at high risk of prostate cancer"

At 4 years, combination therapy resulted in significantly superior improvements from baseline in BII and IPSS Q8 than either monotherapy; these benefits were observed from 3 months onwards compared with dutasteride and from 9 months (BII) or 12 months (IPSS Q8) onwards compared with tamsulosin. Also at 4 years, the PPSM questionnaire showed that a significantly higher proportion of patients was satisfied with, and would request treatment with, combination therapy compared with either monotherapy. Conclusions: Combination therapy (dutasteride plus tamsulosin) provides significantly superior improvements in patient-reported quality of life and treatment satisfaction than either monotherapy at 4 years in men with moderate-to-severe BPH symptoms" - See dutasteride at OffshoreRx1.com.
