| Low-carb diet may stunt prostate tumors
DURHAM, N.C., Nov. 14 Tumor growth was stalled and survival rates lengthened in mice fed a low-carbohydrate diet, U.S. researchers found.
The study, published in the journal Prostate, found mice fed a low-fat but high-carbohydrate diets had larger tumors. The mice on a diet high in both fat and carbohydrates had the biggest tumors and the worst survival rates.
"This study showed that cutting carbohydrates may slow tumor growth, at least in mice," lead researcher Dr. Stephen Freedland, of Duke University Medical Center, in Durham, N.C., said in a statement. "If this is ultimately confirmed in human clinical trials, it has huge implications for prostate cancer therapy through something that all of us can control, our diets."
The researchers hypothesized carbohydrates in the diet affect the levels of serum insulin and a related substance known as insulin-like growth factor in the body.
Hyperthermia Combined with Radiation and Androgen Therapy Provides ...
BSD Medical Corp. (AMEX:BSM) today announced that the International Journal of Hyperthermia has published the preliminary results of a phase II clinical study involving 144 patients with locally advanced prostate cancer. In this study BSD Medical's BSD-2000 hyperthermia system was used to deliver local hyperthermia combined with conformal radiation therapy and androgen suppression therapy in the treatment of prostate cancer. Hyperthermia combined with radiation and androgen therapy demonstrated results in survival similar to treatments using higher radiation doses, with no significant side effects associated with either hyperthermia or radiation therapy. The report is entitled "Conformal radiotherapy plus local hyperthermia in patients affected by locally advanced high risk prostate cancer: Preliminary results of a prospective phase II study" (see Int.
Sun exposure may outweigh the cancer risks for Vitamin D deficient ...
The study found that Vitamin D levels, which were calculated based on sun exposure, correlated with better survival rates for cancer victims.
People in sunnier, southern latitudes, with higher estimated Vitamin D levels, were significantly less likely to die from their malignancies than people in northern latitudes, according to the paper in the Proceedings of the National Academy of Sciences, (PNAS).
""In previous work, we have shown that survival rates for (prostate, breast, colon and lung) cancers improve when the diagnosis coincides with the season of maximum sun exposure, indicating a positive role for sun-induced vitamin D in prognosis - or at least that a good vitamin-D status is advantageous when combined with standard cancer therapies,"" said Richard Setlow, a biophysicist and one of the paper's authors.
