Hypofractionated, Dose Escalation Radiotherapy for High Risk Adenocarcinoma of the Prostate

Centres using IMRT will use the dose painting technique to treat the prostate + proximal 1-cm SV to 6800 cGy in 25 fractions while the pelvic lymph nodes will receive 4500 cGy in 25 fractions. For patients with T3b, the whole SV is to be treated to 6800 cGy. Institutions using 3D-CRT will deliver the required dose to the pelvic volume (including pelvic lymph nodes and boost volume) - 4500 cGy - and a concomitant boost to the prostate and proximal 1-cm (or the whole SV if involved) SV to 6800 cGy.

"The first phase: whole pelvis including the prostate and regional lymph nodes treated with 4400 cGy in 22 fractions.~The second phase: prostate + proximal 1-cm SV treated with 3200 cGy in 16 fractions.~For patients with T3b, the whole SV is to be treated to 7600 cGy."
