To evaluate the efficacy of systemic ifosfamide, cisplatin (CDDP) combination as first line treatment followed by intraperitoneal (IP) chemotherapy with carboplatin (CBCDA) and etoposide as consolidation in patients with stage III and IV epithelial ovarian cancer. A total of 40 patients with stage III and IV ovarian cancer were entered into the study. Ifosfamide 1 g/m2 plus mesna 1 g/m2 was given as six hour infusion daily for six days and CDDP 75 mg/m2 was given on day seven. Patients completing six cycles of systemic therapy underwent second look laparotomy followed by four cycles of IP chemotherapy with CBCDA 300 mg/m2 and etoposide 200 mg/m2. Of the 40 patients entering the protocol 27 patients completed six cycles with a complete remission (CR) of 65% and overall response of 67.5%. Twenty-two patients underwent second look laparotomy with pathological CR in ten patients, microscopic disease in seven and macroscopic disease in five. Eleven patients completed four cycles of IP chemotherapy. At 52 months was the overall survival (OS) was 36%. The disease free survival (DFS) at 45 months was 38%. Factors affecting OS were ascites (p < 0.011), stage (p < 0.04), weight change (p < 0.017), residual disease (p < 0.001), number of chemotherapy cycles (p < 0.0001) and IP chemotherapy (p < 0.006). Presently 35% patients are alive in CR, 15% are alive with disease, one patients has been lost to follow up while 47.5% have died. Of these four patients had progressive disease, seven relapsed, four died due to treatment related complications and two died in CR due to other causes. Subset analysis of 22 patients who had second look laparotomy and completed four cycles of IP chemotherapy revealed a distinct survival advantage. IFOS + CDDP is an effective combination as first time treatment in advanced ovarian cancer. IP chemotherapy is effective as consolidation and seems to provide a significant survival advantage. Further studies with larger number of patients need to be done to confirm these results.
