Vitamin E, selenium and soy in combination does not prevent prostate cancerApril 27, 2009The combination therapy of vitamin E, selenium and soy does not prevent the progression from high-grade prostatic intraepithelial neoplasia (HGPIN) to prostate cancer, according to the new research presented at the 104th Annual Scientific Meeting of the American Urological Association (AUA). The study confirms the findings of the Selenium and Vitamin E Cancer Prevention Trial (SELECT) and expands knowledge of the affect soy has on prostate cancer. Canadian researchers divided 303 men, with an average age of 62, into two randomized groups. All participants had HGPIN, a precursor to invasive prostate cancer, as confirmed by a central pathology review in at least one of two biopsies within 18 months prior to randomization. The combination treatment was administered daily for three years with follow-up prostate biopsies at six, 12, 24 and 36 months. Supplementation was discontinued if a man developed invasive disease. Study results show that 26.4 percent of patients developed invasive prostate cancer. Baseline, age, weight and testosterone levels did not predict the development of cancer. "Unfortunately, as this study shows, we have yet to find a dietary supplement that will reliably prevent prostate cancer. The results of this study support the findings of the SELECT trial which also demonstrated no benefit using Vitamin E and selenium," said Christopher Amling, MD, an AUA spokesman. "These studies highlight the importance of conducting randomized trials of these agents since many of these supplements are promoted falsely to the general public as having beneficial effects on cancer prevention and progression."

The November issue of European Urology, the official journal of the European Association of Urology, features an article focussing on prostate specific antigen (PSA) velocity and early cancer detection. It has been suggested that changes in PSA over time aid prostate cancer detection. New Synthetic Molecules Trigger Immune Response to HIV and Prostate Cancer Researchers at Yale University have developed synthetic molecules capable of enhancing the body's immune response to HIV and HIV-infected cells, as well as to prostate cancer cells. Their findings, published online in the Journal of the American Chemical Society, could lead to novel therapeutic approaches for these diseases. Chemo-radiation before prostate removal may prevent cancer recurrence Researchers in the Oregon Health & Science University Knight Cancer Institute and the Portland Veterans Affairs Medical Center have found a combination of radiation therapy and chemotherapy given before prostate removal is safe and may have the potential to reduce cancer recurrence and improve patient survival. Blood vessels might predict prostate cancer behavior A diagnosis of prostate cancer raises the question for patients and their physicians as to how the tumor will behave. Will it grow quickly and aggressively and require continuous treatment, or slowly, allowing therapy and its risks to be safely delayed? Short-term hormone therapy and intermediate dose radiation increases survivial for early stage prostate cancer Short-term hormone therapy given prior to and during intermediate dose radiation treatment for men with early stage prostate cancer increases their chance of living longer, compared to those who receive the same radiation alone. Task force develops new radiation guidelines for brachytherapy Radiation dose delivered to the prostate and nearby organs in every brachytherapy procedure should be carefully analyzed using post-implant CT or MRI and uniformly documented in every patient. 1 disease, not 1 demographic The Asian continent has nearly four billion people living in 47 different countries, and each of these groups has their own unique set of health issues. But when they come to the United States, they're often lumped into one large demographic: "Asian/Pacific Islander." Cancer survivors may not be getting the help they need to stop smoking More than a quarter of cancer survivors who still smoke have not been advised to quit smoking by their health care providers in the last year, according to a study published by researchers at Fox Chase Cancer Center in the current issue of the Journal of General Internal Medicine. Experts issue call to reconsider screening for breast cancer and prostate cancer Twenty years of screening for breast and prostate cancer - the most diagnosed cancer for women and men - have not brought the anticipated decline in deaths from these diseases, argue experts from the University of California, San Francisco and the University of Texas Health Science Center at San Antonio in an opinion piece published in the "Journal of the American Medical Association." Detecting the undetectable in prostate cancer screening A team of Northwestern University researchers, using an extremely sensitive tool based on nanotechnology, has detected previously undetectable levels of prostate-specific antigen (PSA) in patients who have undergone radical prostatectomy.
