Primary androgen deprivation therapy ineffective for most men with early prostate cancer
Date:3/17/2014

te cancer is widespread. Despite the lack of randomized clinical trials to test its effectiveness, recent studies have reported it as the second most common treatment, after radiotherapy, for clinically localized prostate cancer among older men age 65 and older. The study did not compare androgen deprivation therapy directly to either surgery or radiation therapy, the two main curative treatment options for prostate cancer.

While the study did not probe the reasons why physicians prescribe the treatment in this setting, it was much more common in older men and those with higher risk of disease progression. Potosky speculates that men and their doctors may feel the treatment is a useful option to delay progression of prostate cancer for men who are not good candidates for, or who prefer to avoid, surgery or radiation due to their side-effects.

"Primary androgen deprivation therapy may be preferable to some men with early stage prostate cancer who would prefer to do something rather than watch and wait for further signs of progression to occur later and then need treatments," Potosky adds. "However, using PADT by itself immediately after diagnosis in the hopes of limiting cancer's progression does not extend survival, according to this study."

The researchers are now using their database of 15,170 patients to examine rates of potential side effects from the treatment.

"Given the aging American population, more men are likely to be faced with prostate cancer so its is very important to understand the whether the risks of primary androgen deprivation therapy outweigh the survival benefit," he says. "Ultimately, this is a decision for men and their doctors to make together, and we hope that our study provides some helpful information to guide these decisions."
