Résumé
BACKGROUND: Promising results were reported with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in peritoneal carcinomatosis. Experiences in India are not published. This is a preliminary report. MATERIALS AND METHODS: From eight patients with peritoneal metastasis, six patients (5 M, 1 F), aged (40‑62 years) were treated with CRS and HIPEC between May 2010 and August 2011 from a single institution. Three had Mucinous Adenocarcinoma of Appendix and one each with Mesothelioma, Ovarian Cancer and Colonic Cancer. Four were earlier treated with systemic chemotherapy and recurred. Pre‑operative peritoneal cancer index (PCI) was calculated based on recent computerized tomography or positron emission tomography scans. Surgical completeness cytoreduction score (CCS) was classified as macroscopically complete (CCS‑0); optimal residual disease ≤2.5 mm in any region (CCS‑1); or grossly incomplete: Residual disease >2.5 mm (CCS‑2) or >25 mm (CCS‑3). They were treated by closed perfusion technique with mitomycin‑C (MCC) and cisplatin at 41‑42°C, for 60 min. RESULTS: Optimal cytoreduction (residual tumor nodules <2.5 mm i.e. CC0 and CC1) was performed in four patients (66.67%). There was no operative mortality or Grade 3 and 4 toxicity. Patients with PCI <11 are alive without recurrence with overall survival of 26‑31 months. Those with PCI >11 had recurrence with overall survival of 3‑19 months. Two patients died at 3 and 9 months. CONCLUSION: CRS and HIPEC is a promising therapeutic option in selected patients with peritoneal carcinomatosis. These results in six patients are preliminary but encouraging. Patient with low PCI had better disease free survival.
