title: Intraperitoneal chromic phosphate therapy after second-look laparotomy for ovarian cancer.
abstract: Between 1973 and 1985, 118 patients in clinical remission after initial surgery and postoperative chemotherapy for epithelial ovarian carcinoma underwent second-look laparotomy at the University of North Carolina. No evidence of disease (NED) was found in 57 of these patients; 43 patients received 15 mCi of radioactive chromic phosphate (32P) suspension given intraperitoneally in the immediate postoperative period. In 29 other patients, only microscopic or minimal residual disease (nodules less than 2 cm in size) was found, seven received 32P alone, ten received 32P and further chemotherapy, and 12 received chemotherapy alone. The 4-year postsecond-look survival of the patients with NED at second-look was 89% for those receiving 32P and 67% for those who had not. The respective figures for patients with minimal residual disease at second-look are 59% versus 22%. Irrespective of treatment, a group at high risk for failure after negative second-look laparotomy has been identified; those with an initial International Federation of Gynecology and Obstetrics (FIGO) stage greater than I and histologic grade greater than 1. A comparison of our data with 18 previously published series, indicates that use of postsecond-look intraperitoneal 32P can improve the progression-free interval, and possibly overall survival, of patients with NED or minimal residual disease without adding significant complications.
