Purpose

Peritoneal mesothelioma (PM) is a rare disease, with a poor prognosis. We decided to prospectively evaluate the prognostic impact of aggressive surgery followed by intraperitoneal chemotherapy with local hyperthermia.

Patients and Methods

In this prospective study 28 patients with PM were treated by cytoreductive surgery (CRS) and intraperitoneal hyperthermic perfusion (IPHP). Mean follow-up was 25,3 months (range: 0,4-70). Twenty-four (86%) patients had malignant disease, 2 (7%) had well-differentiated papillary mesothelioma and 2 (7%) had multicystic PM. Seventeen (58,6%) patients received preoperative chemotherapy. Twenty-one cases (72,4%) underwent optimal cytoreduction (residual disease <2.5mm). One patient underwent the procedure twice due to locoregional progression. IPHP was performed with closed abdomen technique, using a preheated polysaline perfusate (42.5°) containing cisplatin + mitomycin C or cisplatin + doxorubicin administered through a heart-lung pump for 60 or 90 minutes.

Results

Five-year overall, disease and progression-free survival was 71, 63 and 51%, respectively. The operative morbidity (grade III), mortality and overall toxicity (grade III-IV) rates were 17%, 0% and 17%, respectively. Twenty-six (96%) out of 27 patients presenting ascites, had a resolution.

Conclusion

Results observed in this series of patients confirms that patients with PM. are responsive to this aggressive therapeutic strategy with long term survival and local disease control.
