Purpose: We examined variation in active surveillance use in Medicare eligible men undergoing expectant treatment for early stage prostate cancer. Materials and Methods: Using SEER (Surveillance, Epidemiology and End Results) and Medicare data we identified 49,192 men diagnosed with localized prostate cancer from 2004 through 2007. Of 7,347 patients who did not receive treatment (ie expectant management) within 12 months of diagnosis we assessed the prevalence of active surveillance (ie repeat prostate biopsy and prostate specific antigen measurement) vs watchful waiting across health care markets. We fit multivariable logistic regression models to examine associations of active surveillance with patient demographics, cancer severity and health care market characteristics…(vermás)
