Radiation in multidisciplinary treatment of children with malignant ovarian tumors.

Thirteen girls with malignant ovarian tumors treated at Memorial Hospital from August 1971 through October 1975 with extensive surgery, multi-drug chemotherapy (T-2 protocol) and postoperative radiation were reviewed. The plan of radiation was to deliver 3,000 rads to the whole abdomen and boost the para-aortic and pelvic area with 1,500 rads in five to six weeks. In only two patients was the radiation conducted as planned. In others the treatment was either interrupted or discontinued due to complications. Four of the thirteen patients are dead. The cause of death in two of these patients was distant metastases; the two other patients died without evidence of tumor due to treatment complications. Three of the nine patients who are alive without evidence of disease have late complications. Following radical surgery, lower doses of radiation given concomitantly with T-2 protocol chemotherapy seem to be sufficient for controlling the disease.
