Abstract

Purpose: To analyze the recent trends in the utilization of external beam radiation therapy (EBRT) and brachytherapy (BT) for the treatment of prostate cancer. Methods and Materials: Using the Surveillance, Epidemiology, and End Results (SEER) database, information was obtained for all patients diagnosed with localized prostate adenocarcinoma between 2004 and 2009 who were treated with radiation as local therapy. We evaluated the utilization of BT, EBRT, and combination BT. +. EBRT by the year of diagnosis and performed a multivariable analysis to determine the predictors of BT as treatment choice. Results: Between 2004 and 2009, EBRT monotherapy use increased from 55.8% to 62.0%, whereas all BT use correspondingly decreased from 44.2% to 38.0% (BT-only use decreased from 30.4% to 25.6%, whereas BT. +. EBRT use decreased from 13.8% to 12.3%). The decline of BT utilization differed by patient race, SEER registry, median county income, and National Comprehensive Cancer Network risk categorization (all p<. 0.001), but not by patient age (p=0.763) or marital status (p=0.193). Multivariable analysis found that age, race, marital status, SEER registry, median county income, and National Comprehensive Cancer Network risk category were independent predictors of BT as treatment choice (all p<. 0.001). Moreover, after controlling for all available patient and tumor characteristics, there was decreasing utilization of BT with increasing year of diagnosis (odds ratio for BT. =. 0.920, 95% confidence interval: 0.911-0.929, p<. 0.001). Conclusions: Our analysis reveals decreasing utilization of BT for prostate cancer. This finding has significant implications in terms of national health care expenditure.
