Effect of Urologists and Medical Oncologists on Treatment of Elderly Men With Stage IV Prostate Cancer

Objectives To examine, among elderly men with incident advanced prostate cancer (PCa), their treatment, in general, and chemotherapy, in particular, in association with a posturologist medical oncologist/hematologist (PUMOH) visit. The role of specialists in the management of advanced PCa is evolving in response to positive chemotherapy trials of PCa. Methods Linked Surveillance, Epidemiology, and End results and Medicare data included patients with Stage IV PCa diagnosed from 1994 to 2002 who had visited a urologist after the diagnosis and received treatment. The visits and treatment were examined, comparing patients with and without PUMOH visits. Results Most (77%) patients received treatment of their PCa and 85% of treated patients had a subsequent visit with a urologist, of whom 91% saw the urologist first (n = 5435). Of these, 43% saw only the urologist, 41% saw a medical oncologist/hematologist, and 32% saw a radiation oncologist. Of the 5435 patients, 16% received chemotherapy and the adjusted odds of chemotherapy receipt were 7.2 times greater (95% confidence interval 6.0-8.7, P P P = .14) among the groups. Conclusions The results of our study have shown that nearly one quarter of men with Stage IV PCa receive no PCa treatment. Although a PUMOH visit is a significant predictor of chemotherapy receipt, many men with advanced PCa received chemotherapy without a medical oncologist/hematologist visit. Black American and elderly men were less likely to receive chemotherapy for advanced PCa.
