Objective: We report a single-institution Phase I or II trial of surgical debulking, intraperitoneal chemotherapy, and immunotherapy followed by whole abdominal radiotherapy in patients with malignant peritoneal mesothelioma.
Methods: Between 1997 and 2000, 27 patients with malignant peritoneal mesothelioma were enrolled: 23 with epithelial subtype and 4 with sarcomatoid or mixed subtype. The treatment regimen consisted of surgical debulking followed by 4 intraperitoneal courses of cisplatin alternating with 4 courses of doxorubicin, 4 doses of intraperitoneal gamma interferon, a second laparotomy with resection of residual disease plus intraoperative intraperitoneal mitomycin and cisplatin heated to 41 degrees C, and finally whole abdominal radiotherapy.
Results: The median overall survival was 70 months with a 3-year survival of 67% (95% confidence interval, 46%-81%). Fourteen patients have died of their disease with a median time to death of 17 months (range, 0.4-71 months) after consenting to treatment. Seven patients are alive without evidence of disease with a median follow-up of 90 months (range, 71-110 months), and 6 are alive with disease with a median follow-up of 86 months (range, 70-106 months). The regimen was well tolerated. There were no patients with Grade III or IV hematological toxicities, 2 patients with Grade III ototoxicity, and 3 patients with Grade III gastrointestinal toxicity.
Conclusion: Based on the results of this study, intensive multimodality therapy appears feasible and effective in this group of patients.
