Abstract

Objective: To report survival results in patients with diffuse malignant peritoneal mesothelioma (MPM) treated with maximal cytoreductive surgery followed by immediate intraperitoneal chemotherapy, and to compare them with the median survival of 12-24 months obtained with the standard treatment based on systemic chemotherapy.

Patients and methods: Twenty-six patients underwent this new regional approach and a median follow-up of 55 months was achieved after this treatment. Complete cytoreductive surgery (residual disease <2 mm) was performed in all but one patient. Intraperitoneal chemotherapy was performed with hyperthermia (4245°C) and oxaliplatin in 22 patients. The last 12 patients additionally received irinotecan. Data were prospectively verified and retrospectively analyzed.

Results: One patient died postoperatively (4%), and morbidity attained 54%. The median survival exceeded 100 months and the overall 5-year survival rate was 63%. This small series lacks the statistical power required to conduct a well-grounded study on prognostic factors, particularly as the completeness of the surgery is not analyzable here. However, the low-grade histological types had a better disease-free survival rate that was of borderline significance compared to their high-grade counterparts.

Conclusion: This new approach combining complete cytoreductive surgery considerably increases the survival of patients with MPM compared with the standard treatment based on systemic chemotherapy.
