Radiotherapeutic alternatives to standard management of adenocarcinoma of the endometrium.
Primary radiotherapy as an alternative management for adenocarcinoma of the endometrium was chosen for 117 patients treated at the University of Michigan Medical Center and University of Virginia Medical Center. Cases were selected for radiation because of contraindications to surgery (52.2%) or by protocol for disease outside the endometrium (47.8%). An overall 5-year actuarial survival rate of 49.6% was attained for all stages, with 55% 5-year survival for disease limited to the uterus or cervix. Stage and grade were the most significant risk factors. The addition of external-beam irradiation did not improve local failure rates or survival. Heyman's uterine packing technique was slightly more successful than uterine "line sources" in controlling local disease (P = 0.08). Treatment-related mortality (0.8%) and morbidity (6.8%) were minimal. Surgery, whenever possible, remains the "best standard therapy" but the radiotherapeutic alternative is of significant benefit for those deemed nonsurgical candidates.
