Abstract

INTRODUCTION

Cytoreductive surgery (SRC) and hyperthermic intraperitoneal chemotherapy (HIPEC) is the recommended treatment approach for peritoneal mesothelioma (PM). Here we present our multimodal treatment experience for PM.

METHODS

Thirty-eight patients were included in the study between January 2009 and December 2017. Clinico-pathological features and treatment results, medical records and intraoperative peritoneal cancer index (PCI) scores of the patients were analyzed retrospectively.

RESULTS

A total of 38 patients (n = 22 women) with a median age of 61 (21-80) were evaluated. SRC was applied to 23 patients (60.5%) and SRC + HIPEC was applied to 18 patients (47.3%). After excluding postoperative early mortal cases (6 patients), longer OS was achieved in patients treated with adjuvant therapy (p = 0.03). PCI value was higher in patients with morbid course. Morbidity was higher in patients with obesity, diabetes mellitus (DM) and CA125 levels above 1000 U / ml.

DISCUSSION AND CONCLUSION

It has shown that adjuvant chemotherapy can improve OS in PM patients receiving SRC + HIPEC. However, multimodal treatments should be carefully evaluated in patients with DM, high PCI, and preoperative CA125 levels above 1000 IU / ml.
