In addition, the sale of an ethanolic GTE sold as a weight-reduction aid was suspended in 2003 after reports associated hepatotoxicity (four cases in Spain and nine cases in France) with its use. [2] Lycopene is found in a number of fruits and vegetables, including apricots, guavas, and watermelon, but the majority of lycopene consumed in the United States is from tomato-based products. You can do this by reducing the number of calories you eat each day and increasing the amount of exercise you do. Clin Med Urol 1: 1-14, 2008. Other prostate health supplements.

In addition, in a N-methyl-N-nitrosourea/testosterone-induced prostate carcinogenesis model, rats fed a tomato paste and FruHis diet had longer survival times than rats fed only with tomato paste or tomato powder. The PJ-supplemented mice exhibited significantly increased life spans compared with the water-fed mice. Many of the medical and scientific terms used in this summary are hypertext linked (at first use in each section) to the NCI Dictionary of Cancer Terms, which is oriented toward nonexperts. At the 45 mg/d dose, serum total estradiol increased (P = .006) with no significant change in serum testosterone. One study [44] administered approximately 300 mg EGCG per day for 1 year without any reported toxicities. Pinto JT, Sinha R, Papp K, et al. Pedrs C, Cereza G, Garca N, et al.

[21] Severe vitamin D deficiency (<12 ng/mL) was associated with increased risk of a prostate cancer diagnosis on biopsy among African American men. Although antioxidant properties of lycopene have been hypothesized to be primarily responsible for its beneficial effects, this study suggests that other mechanisms mediated by steroid hormones may also be involved. ABCA1 mediates cholesterol efflux, and PPAR has been shown to inhibit the growth and differentiation of prostate cancer cells. [21] For more information about trials on therapies that include lycopene, see the Multicomponent Therapies section. Nutr Cancer 59 (2): 163-8, 2007. [21] Serum 25(OH)D levels were obtained from 667 men in Chicago who underwent a first prostate biopsy for an elevated PSA level or an abnormal digital rectal exam. [10] Interestingly, however, a rare condition caused by mutations in the adenosine triphosphate-binding cassette (ABC) transporter ABCG5 or ABCG8 genes results in an inherited sterol storage disease with markedly increased serum concentrations of plant sterols such as sitosterol and leads to premature atherosclerosis and large xanthomas. Am J Pathol 178 (2): 872-80, 2011. Clinical trials have suggested that soy may lower PSA levels, and that green tea may help men who are at high risk for prostate cancer lower their risk. [16] One study also focused on the ATBC Study and investigated whether serum alpha-tocopherol levels affected survival time in men diagnosed with prostate cancer. The study explored the summary relative risk (RR) assessed per 10 ng/mL increments in circulating 25(OH)D concentration levels. The bioavailability of lycopene has been examined and demonstrated in several studies relating lycopene to prostate cancer and other diseases. : Impact of dietary selenium intake on cardiac health: experimental approaches and human studies.

[36-38] Studies using varying doses (400 mg, 800 mg EGCG) of GTCs and Polyphenon E administered in single and repeated dosing schedules for 3 to 6 weeks have reported median maximum concentrations of EGCG ranging from 68.8 ng/mL to 390.36 ng/mL (see Table 1). Wright ME, Weinstein SJ, Lawson KA, et al. The genetic variant rs11568820 appeared to increase the magnitude of association between deficient serum vitamin D levels and aggressive prostate cancer (OR, 3.64; 95% CI, 1.1211.75; P = .05). [24] However, in a 2009 study of prostate cancer patients, men with higher plasma selenium levels were at greater risk of being diagnosed with aggressive prostate cancer (relative risk, 1.35; 95% confidence interval [CI], 0.991.84). Treatment of CWR22Rv1 cells (prostate cancer cells that express the androgen receptor and secrete PSA) with POMx (10100 g/mL concentrations of pomegranate fruit extract) led to the inhibition of cell growth, a dose-dependent decrease in androgen receptor protein expression, and dose-dependent reductions in PSA protein levels. Prostatic lycopene concentration was the only difference between those whose repeat biopsy showed HGPIN, prostatitis, or prostate cancer. : Low prostate concentration of lycopene is associated with development of prostate cancer in patients with high-grade prostatic intraepithelial neoplasia. Additional evidence that Zyflamend promotes apoptosis in cancer cells was obtained in laboratory and animal studies reported in 2012. Bushman JL: Green tea and cancer in humans: a review of the literature. Muti P, Awad AB, Schnemann H, et al. : Prevalence and correlates of vitamin and supplement usage among men with a family history of prostate cancer. [37] More than 35,000 men, aged 50 years or older, from more than 400 study sites in the United States, Canada, and Puerto Rico, were randomly assigned to receive vitamin E (alpha-tocopherol acetate, 400 IU/d) and a placebo, selenium (L-selenomethionine, 200 g/d) and a placebo, vitamin E and selenium, or two placebos daily for 7 to 12 years. In an open label, phase II clinical study, prostate cancer patients scheduled for radical prostatectomy consumed four Polyphenon E tablets containing tea polyphenols, providing 800 mg EGCG daily until surgery. Brown MJ, Ferruzzi MG, Nguyen ML, et al. In sum, intervention with potent vitamin D compounds in TRAMP mice slowed androgen-stimulated tumor progression but, over time, may have led to more aggressive disease as indicated by increased distant metastases (P = .0823). [42,43], Toenail selenium concentrations were examined in two-case cohort subset studies of SELECT participants. : Herbal and vitamin supplement use in a prostate cancer screening population. One hundred ninety men who participated in a large epidemiological study underwent radical prostatectomy for clinically localized prostate cancer.

This PDQ cancer information summary for health professionals provides comprehensive, peer-reviewed, evidence-based information about the use of nutrition and dietary supplements for reducing the risk of developing prostate cancer or for treating prostate cancer. [46] Muscle mass was measured using bioelectric impedance analysis (BIA), and strength was measured before and after supplementation. Human studies evaluating isoflavones and soy for the prevention and treatment of prostate cancer have included epidemiological studies and early-phase trials. : Selenium supplementation and prostate cancer mortality. Grade 2 hypercalcemia was observed in two of four patients receiving 96 g per week (3,900 IU) of calcitriol and was denoted nontolerable. Increased oral bioavailability occurs when GTEs are administered on an empty stomach after an overnight fast. In another study, 119 male TRAMP mice and 119 C57BL/6J mice were treated orally with one of three doses of Polyphenon E (200, 500, or 1,000 mg/kg/d) in drinking water ad libitum, replicating human-achievable doses.
Common Vitamins and Supplements to Treat prostate-cancer - WebMD The combination treatment inhibited proliferation in four of five cell lines to a greater extent than did treatment with docetaxel alone. Am J Med 109 (8): 654-64, 2000. In a U.S. trial, 400 mg of EGCG containing Polyphenon E was administered for 1 year to nonfasting men with HGPIN and atypical small acinar proliferation. While there was no change in PSA levels between the groups after 6 months, the participants who received supplements reported improved quality of life and showed decreases in low-density lipoprotein cholesterol and total cholesterol. : Association of MnSOD AA Genotype with the Progression of Prostate Cancer.

Metallomics 3 (2): 162-8, 2011. The findings indicated that 0.25 L/mL to 2 L/mL of Zyflamend produced decreases in 5-LOX and 12-LOX expression in PC3 prostate cancer cells (cells that have high metastatic potential).
Vitamin E and prostate cancer: Where do we stand? In summary, the finding that men with the AA genotype who received pomegranate extract had greater lengthening of PSADT (i.e., slower progression of disease) than did men in the placebo arm, along with the safe profile of PJ and extract in three large studies, suggest that there may be benefit in further studies in the AA MnSOD subpopulation. Stroomberg HV, Vojdeman FJ, Madsen CM, et al. Napora JK, Short RG, Muller DC, et al. Men received either lycopene supplements (30 mg/d) or no intervention twice daily for 3 weeks before radical prostatectomy. This suggests that specific structural features of pectin may be responsible for its ability to induce apoptosis in prostate cancer cells. If you are a Mayo Clinic patient, this could Once a prostate cancer diagnosis has been made, your doctor works to determine the extent (stage) of the cancer. [19], The effects of MSeA and methylselenocysteine (MSeC) have also been explored in a transgenic model of in situ murine prostate cancer development, the transgenic adenocarcinoma of the mouse prostate (TRAMP) mouse. However, these early-phase studies have not demonstrated any significant changes in serum PSA or PSA-doubling time, [40-43] with one study suggesting modulation of systemic soluble and cellular biomarkers consistent with limiting inflammation and suppression of myeloid-derived suppressor cells [43] (see Table 6). One clinical trial suggests that preventative use of lycopene supplements may reduce the spread of localized prostate cancer, but there is no other proof from clinical trials that lycopene can treat cancer. Because dietary supplements are not formally reviewed for manufacturing consistency, ingredients may vary considerably from lot to lot and there is no guarantee that ingredients claimed on product labels are present (or are present in the specified amounts). Several phase I-II randomized clinical studies have examined isoflavones and soy product for bioavailability, safety, and effectiveness in prostate cancer prevention or treatment.

Serum alpha-tocopherol and gamma-tocopherol levels and prostate cancer risk were examined in participants in the Prostate, Lung, Colorectal and Ovarian (PLCO) Screening Trial. GCP = genistein combined polysaccharide; GI = gastrointestinal; PCa = prostate cancer; RCT = randomized controlled trial. Most of the side effects were expected toxicities related to the chemotherapy. Both naturally occurring and synthetic organic forms of selenium have been shown to decrease the growth and function of prostate cancer cells. Although statistically significant decreases in gene expression occurred in LNCaP cells following treatment with POMx and in DU-145 cells following treatment with EA and POMx, significant decreases in gene expression and androgen receptor occurred in LNCaP-AR cells following all of the treatments. Prostate Cancer Prostatic Dis 9 (4): 407-13, 2006. : Vitamin E and the risk of prostate cancer: the Selenium and Vitamin E Cancer Prevention Trial (SELECT). Nineteen percent of enrolled patients had at least a 50% reduction in PSA levels by the end of treatment (95% CI, 7%31%; P = .002). Moreover, apo-12-lycopenal, a lycopene metabolite, reduced prostate cancer cell proliferation and may modulate cell-cycle progression. The researchers postulated that, because it has a lower molecular weight, PectaSol-C may have better bioavailability than PeS. : Weekly high-dose calcitriol and docetaxel in metastatic androgen-independent prostate cancer.
