Study Examines Link Between Alcohol Consumption and Prostate Cancer Risk
Researchers led by Zhihong Gong Ph.D. of the University of California San Francisco have labeled their research inconclusive in terms of the risk alcohol consumption presents in relation to prostate cancer, indicating further research must be conducted. Even with this conclusion, the findings from their work is still worth consideration.
This group of researchers examined the associations of total alcohol, type of alcoholic beverage and drinking patterns of total, low- and high-grade prostate cancer. To conduct this process, researchers used data from more than 10,000 men participating in the Prostate Cancer Prevention Trial (PCPT).
Those participants who reported heavy alcohol consumption (at least 50 g of alcohol per day) and regular heavy drinking (at least four drinks per day on at least five days per week) were twice as likely or more to be diagnosed with high-grade prostate cancer. Less heavy drinking was not associated with risk.
Researchers also compared the drinking patterns with treatment outcome among men enrolled on the placebo-controlled trial of the drug finasteride. Results from this part of the test showed that the drug’s ability to lower prostate cancer risk was blocked in those men consuming more than 50g of alcohol per day.
From this study, researchers conclude that heavy, daily drinking increases the risk of high-grade prostate cancer and heavy drinking made finasteride ineffective in reducing prostate cancer risk.
