High-dose radiotherapy for localized prostatic cancer

Between 1970 and 1983, 477 consecutive patients with clinically localized prostatic adenocarcinoma were treated with primary external-beam radiotherapy. With a minimum follow-up period of 60 months, the five and 10 year survival rates were 59% and 33%, respectively. The five year survival rate was 89% for patients with stage A disease, 59% for stage B disease and 25% for stage C disease; it was 79% for patients with well-differentiated carcinomas, but only 37% for patients with high-grade tumours. The overall local in-field control rate was 88%. The role of local versus extended field radiotherapy for curative treatment of prostatic cancer is discussed in some detail. High-dose radiotherapy to localized prostatic cancer offers significant advantages over radical surgery and is associated with an excellent local control rate, which can be achieved with an acceptable degree of early morbidity
