Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Peritoneal Carcinomatosis

Peritoneal carcinomatosis (PC) is a common presentation of several gastrointestinal and gynecological malignancies. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) is a treatment regimen recently introduced in Pakistan for PC. The goal of cytoreductive surgery is complete removal of macroscopic disease. HIPEC is administered following surgery, with the aim of eliminating disease at a microscopic level. In this study, 11 patients, who underwent CRS+HIPEC at the Shifa International Hospital, Islamabad, Pakistan, were selected. Disease severity was classified using PCI score. There were 54.5% women and 45.5% men with mean age of 48.5 ± 12.5 years. The mean PCI score was 20.3 ± 3.4. The mean time from diagnosis was 12.7 ± 11.6 months. A complete tumor resection (CC-0) was achieved in 10 (90.9%) patients, while the rest were CC-1. The duration of HIPEC circulation was 90 minutes in every patient. Postoperative morbidity was observed in 2 (18.2%) patients. No 30-day perioperative mortality was seen. It was concluded that with effective patient selection, surgical skills and center experience, CRS+HIPEC can have low perioperative morbidity and mortality, and complete cytoreduction leads to prolonged overall survival.
