Abstract

Background: In the past, diffuse malignant peritoneal mesothelioma (DMPM) was regarded as a preterminal condition. The length of survival was dependent upon the aggressive versus indolent biologic behavior of the neoplasm. The overall median survival was ~1 year after systemic chemotherapy. Cytoreductive surgery (CRS) combined with perioperative intraperitoneal chemotherapy (PIC) has been used as a treatment alternative, but the efficacy of this combined treatment remains to be established.

Patients and methods: Searches for relevant studies published in peer-reviewed medical journals on CRS and PIC for DMPM before May 2006 were carried out on six databases. The reference lists of all retrieved articles were reviewed for further identification of potentially relevant studies. Expert academic surgeons in Washington, DC, USA were asked whether they knew about any important unpublished data. Two investigators independently evaluated each study according to predefined criteria. The quality of each study was assessed. Clinical effectiveness was synthesized through a narrative review with full tabulation of results of all included studies.

Results: Seven prospective observational studies from six tertiary institutions were available, allowing 240 DMPM patients for assessment. The median survival ranged from 34-92 months. The 1-, 3- and 5-year survival varied from 60% to 88%, 43% to 65% and 29% to 59%, respectively. The perioperative morbidity varied from 25% to 40% and mortality ranged from 0% to 8%.

Conclusions: This systematic review evaluated the current evidence for CRS and PIC for DMPM. Seven observational studies were available for assessment, which demonstrated an improved overall survival, as compared to historical controls, using systemic chemotherapy and palliative surgery.
