One of the common therapies used in prostate cancer are drugs that interfere with a man’s production of testosterone. While this does slow tumor growth, there is a downside. With low testosterone men are at higher risk of forming blood clots in their legs, lungs and brain, not to mention sexual dysfunction, depression and chronic fatigue. As a consequence, many men end up taking anticoagulants to prevent those blood clots. An interesting paper just published shows that men who use anticoagulants have significantly better survival from their cancers than men who do not need these drugs. This intriguing bit of data is causing researchers to take a look at the anticoagulants, such as warfarin and heparin, to see if they might have anticancer properties that have not previously been recognized. Once more, studies designed to look at one thing, raise more intriguing new questions than they answer.
