PURPOSE: In the TROG 96.01 trial 6 month neo-adjuvant androgen suppression (NAS) and radiotherapy (RT) for locally advanced prostate cancer prevented distant progressions (DPs) when compared to RT alone, but 3 months did not. We ask why? METHODS: Between 1996 and 2000, 802 men with T2-4 N0 M0 prostate cancers received RT alone (0 month NAS) to 66 Gy, 3 months or 6 months NAS before RT. Interval hazards and cumulative incidences of DP were compared using competing risks methodology. RESULTS: In the first 4 follow-up years 39, 40 and 26 DPs were diagnosed in subjects treated with 0, 3 and 6 month NAS, respectively. Compared with 0 month, significant reductions in PSA doubling time in subjects ..
