The abstract for the initial results of RTOG 9408 are published in the Red Journal - ~2000 patients with T1b-2b prostate cancer were randomized to 66.6Gy +/- 4 months of ADT starting 2 months prior to RT start. 61% had GS 6 or less, about half were T1, half T2. Result demonstrated a statistically significant improvement in OS at 12years (51% vs 46%, p=0.03).
Of course one critique is that the overall RT dose is too low by todays standards, but this supports the D'Amico trial's findings and confirms potential benefit of brief ADT in intermediate and even some low risk patients. The manuscript will be eagerly awaited...
