Postoperative abdominopelvic radiation therapy for ovarian cancer
From 1963 through 1984, 74 patients with Stage I, II, or III epithelial ovarian cancer who completed a total hysterectomy and debulking procedure and had less than 2 cm residual disease were treated with whole abdominal and pelvic boost radiation therapy (WAP) at Yale-New Haven Hospital. WAP consisted of a whole abdominal dose of 1750 to 2500 cGy (at 100-160 cGy per fraction) and a total pelvic dose of 4000-4600 cGy. Based on stage, amount of residual disease, pathologic type, and grade of tumor, the 74 patients were classified into a favorable group (FG) and an unfavorable group (UG) using the classification scheme developed at the Princess Margaret Hospital (PMH). The actuarial survival at 10 years for the FG patients was 77% (+/- 10%, 95% confidence limits) and for the UG patients was only 7% (+/- 13%). Local control of disease in the abdomen and pelvis was 87% in the FG and only 36% in the UG. Severe long-term complications occurred in 7% of the patients and consisted of small bowel obstruction. Our results strongly indicate that the PMH classification of FG and UG is useful in our patient population in determining which subgroup of patients should be offered WAP.
