Moderate drinking positive for prostate cancer
Alcohol doesn’t appear to increase the risk of developing metastatic prostate cancer or increase the risk of death in patients with the disease.
A prospective cohort study, published in the Journal of Clinical Oncology, looked at alcohol intake among 47 568 cancer-free men at risk of prostate cancer and 5182 men diagnosed with nonmetastatic prostate cancer men.
Researchers found that alcohol drinkers had a lower risk of developing metastatic prostate cancer (any versus none: HR, 0.84 [95% CI, 0.71–0.99]). Total alcohol intake among patients with prostate cancer was not associated with progression to metastatic prostate cancer (HR, 0.99 [95% CI, 0.57 to 1.72]), whereas moderate red wine intake was associated with a lower risk (HR, 0.50 [95% CI, 0.29–0.86]). Compared with no alcohol, 15 to 30 grams of alcohol per day, after prostate cancer diagnosis, was associated with a lower risk of death (HR, 0.71 [95% CI, 0.50–1.00]), as was red wine (HR, 0.74 [95% CI, 0.57–0.97]).
The authors conclude that cancer-free men who drink moderate amounts of alcohol have a slightly lower risk of metastatic prostate cancer compared with abstainers. Among men with prostate cancer, red wine was associated with a lower risk of progression to metastatic disease. These associations require additional study but provide reassurance that moderate alcohol consumption is safe for patients with prostate cancer, they say.
