Abstract

Objective To assess the treatment recommendations from a nationally representative sample of radiation oncologists and urologists on adjuvant radiotherapy for patients with pathologically advanced prostate cancer after radical prostatectomy. Methods From a random sample of 1422 physicians (n = 711 radiation oncologists; n = 711 urologists) in the American Medical Association Masterfile, a mail survey queried treatment recommendations for adjuvant radiotherapy that varied by the following pathologic features: extraprostatic extension (pT3a) vs seminal vesicle invasion (pT3b), Gleason 7 vs Gleason 8-10, and margin negative (MN) vs margin positive (MP). Pearson chi-square and multivariable logistic regression were used to test for differences in treatment recommendations by physician specialty. Results Response rates for radiation oncologists and urologists were similar (44% vs 46%; P =.42). Radiation oncologists were more likely to recommend adjuvant radiotherapy than urologists for all the varying pathologic scenarios from pT3a, Gleason 7, and MN (42.5% vs 9.7%; adjusted odds ratio [OR]: 7.82, P
