ORLANDO—Body mass index (BMI) may be useful in identifying patients at increased risk for competing mortality following radical prostatectomy for localized prostate cancer (PCa), according to a study presented at the American Urological Association 2014 annual meeting.

In a study of 2,131 PCa patients, those with a BMI of 30 kg/m2 or higher (obese) had a significantly greater 10-year overall mortality rate compared with men with a lower BMI (19.6% vs. 13.6%). Obese patients also had significantly higher 10-year rates of death from non-cancer causes (8.5% vs. 5.2%) and from competing causes overall (15.1% vs. 9.4%).

The researchers also observed a non-significant trend toward increased mortality from second cancers among obese patients. Obese and non-obese patients did not differ significantly with respect to 10-year PCa-specific mortality (4.5% vs. 4.2%).
