Trends in patterns of care for prostatic cancer, 1974-1983: results of surveys by the American College of Surgeons.

Data from a recent survey of patterns of care for prostatic cancer sponsored by the American College of Surgeons suggest several trends compared to similar data from a decade ago. The observed differences include increased diagnosis of localized cancer, and increased use of acid phosphatase determinations, bone scans, radical retropubic prostatectomy, radiotherapy (particularly interstitial techniques) and orchiectomy. In contrast, use of bone surveys, perineal prostatectomy and hormonal therapy has decreased. Transurethral resection continues to be the most common means to establish the diagnosis of prostatic cancer but the data do suggest that in more patients the tumors are being staged and graded. Five-year survival rates appear to be improving for all stages, and for white and black patients. Survival of black patients continues to lag behind that of white subjects, presumably owing to the more advanced stage of disease at diagnosis observed in these data. These findings may have important implications for understanding trends in survival of patients with this disease.
