OHSU Cancer Institute researchers find novel chemo drug helps treat prostate cancerJune 02, 2008International study of sagopilone shows promise in some cases of advanced prostate cancer PORTLAND, Ore. - Men with a certain type of prostate cancer have been shown to respond to a new chemotherapy drug, Sagopilone, plus prednisone in an international trial led by Oregon Health & Science University Cancer Institute researchers. The research involved men with androgen-independent prostate cancer that has metastasized, meaning their cancer has spread beyond the prostate and is not longer responding to hormonal therapies. This is the most advanced form of prostate cancer. Prostate cancer is the most common type of cancer in men in the United States, where it is responsible for more male deaths than any other cancer, except lung cancer.
"We are showing solid activity that this drug shows promise," said Tomasz Beer, M.D., principal investigator. He is the Grover C. Bagby Endowed Chair for Cancer Research, director of the Prostate Cancer Research Program at the OHSU Cancer Institute and associate professor of medicine (hematology/medical oncology), OHSU School of Medicine. This research will be presented Saturday, May 31 at 8 a.m. at the annual American Association of Clinical Oncology in Chicago. Of the 37 study participants taking the Sagopilone and prednisone long enough to be evaluated, the majority showed positive results in the reduction of their prostate specific antigens, or PSA. PSA is often elevated in the presence of prostate cancer. During the three-month trial thirteen study participants had a more than 50 percent reduction in their PSA; 23 showed a 30 percent reduction; one who had radiographic measurable disease showed complete response; and four had unconfirmed prostate response. A 30 percent reduction in PSA levels in three months is a strong indicator of survival. Sagopilone, a fully synthetic derivation, is a new class of drug that inhibits growth and the spread of malignant cell, similar to docetaxel, which has been the gold standard for this type of hormone independent prostate cancer. Docetaxel, however, it is not a cure and not all patients benefit from it. For this reason, Beer and colleagues are committed to searching for new drugs that will be effective against advanced prostate cancer. "We look forward to completing this study and to the further investigation of Sagopilone as a new treatment option for men with advanced prostate cancer," said Beer.

Hormone therapy before radiation seed implants for prostate cancer Men over 70 years of age with early-stage prostate cancer have 20 percent higher mortality if they are treated first with hormone therapy before being treated with radiation seed implants (brachytherapy), compared to men who are treated with brachytherapy alone. Newly found gene variants account for kidney diseases among African-Americans For the first time, researchers have identified variations in a single gene that are strongly associated with kidney diseases disproportionately affecting African-Americans.

Common painkillers lower levels of prostate cancer biomarker Common painkillers like aspirin and ibuprofen appear to lower a man's PSA level, the blood biomarker widely used by physicians to help gauge whether a man is at risk of prostate cancer. Anti-inflammatory drugs may mask prostate cancer marker Regular use of nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin and ibuprofen, may reduce serum levels of the prostate biomarker, PSA (prostate specific antigen), and hence may alter the detection of prostate cancer in individuals who take these medications. Too much calcium in blood may increase risk of fatal prostate cancer Men who have too much calcium in their bloodstreams may have an increased risk of fatal prostate cancer, according to a new analysis from Wake Forest University School of Medicine and the University of Wisconsin. Height linked to risk of prostate cancer development and progression A man's height is a modest marker for risk of prostate cancer development, but is more strongly linked to progression of the cancer, say British researchers who conducted their own study on the connection and also reviewed 58 published studies. Health risk behaviors associated with lower prostate specific antigen awareness According to a study conducted at Columbia University Mailman School of Public Health, health risk behaviors such as smoking and obesity are associated with lower awareness of the Prostate Specific Antigen (PSA), which could lead to a lower likelihood of undergoing actual prostate cancer screening.
