Analysis Finds Bladder Cancer Patients Unlikely to Benefit from Selenium Supplements, According to Cancer Monthly

Researchers in Italy say their review of studies on the link between selenium and malignancies like bladder cancer turned up too little evidence to support supplementation.

To date, no convincing evidence suggests that selenium supplements can prevent cancer in humans.

Raleigh, NC (PRWEB) April 04, 2014

Italian scientists say patients fighting bladder cancer and other types of cancer are not likely to get any benefit from the metalloid nutritional supplement, selenium. The new meta-analysis has just been posted on the Cancer Monthly website and can be read by clicking here.

Researchers at Italy’s University of Modena and Reggio Emilia in Modena examined dozens of previous studies purporting to find a link between higher levels of selenium and/or selenium supplementation and a lower risk of certain cancers, including bladder cancer, a cancer more common among diabetics who have taken Actos. Their conclusion? The evidence is not there.

“The most pronounced decreases in risk of site-specific cancers [with selenium] were seen for stomach, bladder, and prostate cancers,” reports the study’s lead author, Dr. Marco Vinceti. “However, these findings have limitations due to study design, quality and heterogeneity that complicate interpretation of the summary statistics.”

The meta-analysis was conducted for the Cochrane Database of Systematic Reviews and included studies on selenium and cancer dating back as far as 1966.

“We all wish there were an easy answer for bladder cancer and other cancers,” says Cancer Monthly Managing Editor Alex Strauss. “But analyses like this one help keep us grounded in reality and focused on the treatments and prevention strategies that are actually likely to make a difference for bladder cancer patients.”
