RTOG 86–10 [5 ] Prospective randomized trial WPRT + Boost (66–70 Gy) ±2 mos. (nADT) and 2 mos. (cADT). (Locally advanced disease). Total: 471 RT + ADT (4 mos) RT (alone). CR of CV death: 14% 11% Significant benefit in ↓ DM, ↑CSS, and ↑DFS, OS advantage for Gleason score <7. RTOG 92–02 [6 ] Prospective randomized trial WPRT + Boost to 65–70 Gy + 2 mos. nADT + 2 mos. cADT ± 2 year aADT Total: 1554 RT + ADT (28 mos.) RT + ADT (4 mos.) CR of CV death: 13.5% 11% Survival advantage for pts. with Gleason score 8–10. D’Amico et al. [7 , 8 ] Prospective randomized trial 45 Gy (prostate and seminal vesicles) + boost to 70 Gy ± 6 mos. ADT (nADT, cADT, or aADT). Total: 206 RT + nADT or cADT or ADT RT (alone) Age: >65 yrs. 6 mos. HT Fatal MIs. 7% 5-6% OS advantage for pts. with hormonal manipulation with minimal or no comorbidities. RTOG 94–13 [9 ] Prospective randomized trial 70.2 Gy (50.4 to WP if on WP arms). 4 arms: WPRT + nADT PORT + nADT WPRT + aADT PORT + aADT Total: 1279 WPRT + nADT + Boost (

) Acute radiation toxicity: WPRT + nADT = (8%) PORT + nADT = (5%) WPRT + ADT = (3%) PORT + ADT = (3%). Grade 3 GI toxicity: WPRT + nADT = 5% PORT + nADT = 1% WPRT + ADT = 2% PORT + ADT = 2% Improved PFS in WPRT + nADT arm as compared to others. TROG 9601 [10 ] Prospective randomized trial 66 Gy + 0 versus 3 versus 6 mos. nADT (T2b-T4). Total: 818 3 arms: RT (alone) RT + 3 mos. nADT RT+ 6 mos. nADT Improvement in 5-year LF, bFFS, and DFS, freedom from salvage with 3 or 6 mos nADT. EORTC 22961 [11 ] Prospective randomized trial 70 Gy (50 Gy WPRT) + 6 mos. cADT versus 3 yrs. on aADT Total: 970 WPRT + 6 mos. cADT WPRT + 3 yrs. aADT No difference in fatal cardiac events (3-4%). More hot flushes and ↓ sexual function 3-year ADT improved overall mortality 19 versus 15.2%.Prostate cancer mortality: 4.7% versus 3.2%. RTOG 94–08 [12 ] Prospective randomized trial 66 Gy ± 2 mos. nADT + 2 mos. cADT Total: 1989 RT (alone) RT + nADT (2 mos.) + cADT (2 mos.) Risk of acute, late GU, GI, and hemat. Toxicities is same in both arms. Grade 4 < 3% Grade 5 < 1% Short-term ADT before and during RT was associated with significantly decreased DSM and increased OS for IR pts. EORTC 22863 [13 ] Prospective randomized trial 70 Gy (50 Gy WPRT) ± 3 year goserelin starting on first day of RT. (T3-T4 or T1-T2 Gleason > 7) Total: 415 RT + Goserelin (aADT) RT (alone) No difference in 10 year cardiac mortality (8–11%) OS and DFS benefit for patients on combined therapy arm. Crook et al. [14 ] Prospective randomized trial 3 or 8 mos. of flutamide or goserelin before 66 Gy RT Total: 378 Flutamide or goserelin (3 mos.) + RT Flutamide or goserelin (8 mos.) + RT — 5-year DFS improvement for high-risk patients in the 8 mos. arm. Nguyen et al. [28 ] Meta-analysis of 8 prospective randomized trials Nonmetastatic unfavourable risk PC pts ± ADT Total: 4141 Nonmetastatic PC + ADT Control group ADT use is not associated with an increased risk of CVD ADT is associated with a lower risk of PCSM and all-cause mortality.
