title: Pattern of care and follow-up of stages A1, B1 prostatic cancers from multicenter group, the National Prostatic Cancer Treatment Group (NPCTG).
abstract: In 1981, the National Prostatic Cancer Treatment Group began an open survey of available A1, B1 prostatic adenocarcinomas to determine outcome and clinical characteristics. Their report as of September, 1985, summarizes the outcome and important features of the survey. The majority of A1 cases had a low tumor grade I and were followed. Stage B1 received surgery or radiation generally. The B1 tumor grade was approximately one-third grade I, II, or III-IV. Presently, symptoms differ, as would be expected. Follow-up data to date have indicated no major changes. In some of the special study cases (12/52), the stage was changed as a result of the central laboratory review.
