The Southwest Oncology Group Genitourinary Committee evolved in 1978 f
rom a combined gynecologic-urologic cancer committee. A significant ca
talyst in this development was the growing interest in prostatic carci
noma, with an initial focus on hormone refractory disease. Clinical st
udies have expanded into combined androgen blockade, untreated metasta
tic disease and localized prostate cancer. Since 1978, more than forty
trials in prostatic carcinoma have been conducted. Currently, seven a
re in progress or under development. Conclusions and future directions
are reviewed. (C) 1995 Wiley-Liss, Inc.
