New biologic information has led to a therapeutic program in Stage III ovarian cancer that considers the whole peritoneal cavity the tumor‐bearing region and that uses intraperitoneal administration of ovarian cancer antiserum, intraperitoneal P‐32, delayed split abdominal irradiation, and chemotherapy. The survival for those patients completing irradiation was 85%. Forty‐nine patients with advanced (Stage III, IV, or recurrent) ovarian cancer have been treated with combinations of the present agents. Twenty‐two patients have received intraperitoneal ovarian cancer antiserum without significant toxicity. Extensive staging has been a requirement for initial evaluation and includes maximal surgical resection, omentectomy, TAH and BSO, nodal biopsies, and peritoneal cytology. Nineteen patients had 5‐mm nodules or less residual disease and were treated with colloidal P‐32, abdominal irradiation, and chemotherapy; five of these patients received intraperitoneal antiserum before cytotoxic therapy. The four‐year cumulative survival is 84%, and the disease‐free survival 43%. A randomized prospective study is now examining the value of antiserum therapy. New experimental data from our laboratory indicate 1) the value of 2/3 biomarkers (alpha globulin and free secretory protein) in following patients for remission of disease and 2) the probability of the development of more effective antiserum with higher specific titer. Studies of the radiosensitivity of ovarian cancer indicate the tumor was not different from other solid tumors. Our studies indicate the role of radiation therapy as a cytoreductive agent should be integrated in multimodality therapy and that the immune system offers new possibilities in amplifying therapeutic results.
