Abstract

The factors which influence decision-making among urologists are not well understood. We evaluated how tumor stage in patients subjected to potentially curative surgery for carcinoma of the prostate affects the self-reported follow-up strategies employed by practicing United States urologists. Standardized patient profiles and a detailed questionnaire based on these profiles were mailed to 4,467 randomly selected members of the American Urological Association (AUA), comprising 3,205 US and 1,262 non-US urologists. The effect of TNM stage on the surveillance strategies chosen by respondents was analyzed by repeated-measures ANOVA. There were 1, 050 respondents who provided evaluable data of whom 760 were from the US. The three most commonly used surveillance modalities by urologists were office visit, serum PSA level, and urinalysis. Nine of the 11 most commonly requested modalities were ordered significantly (p<0.001) more frequently with increasing TNM stage. This effect persisted through 10 years of follow-up, but the differences across stage were tiny. Fifty-five percent of US respondents do not modify their strategies at all according to the patient's TNM stage. Most American AUA members performing surveillance after potentially curative radical prostatectomy for otherwise healthy patients use the same follow-up strategies irrespective of TNM stage. These data permit the rational design of a randomized clinical trial of two alternate follow-up plans. The two trial arms would employ office visits, blood tests, and urinalyses at different frequencies based on current actual practice patterns; there would be no imaging tests in either arm.
