[Cytoreductive surgery with intraperitoneal chemotherapy in patients with colon cancer and peritoneal carcinomatosis].
The efficacy of cytoreductive approach for colon cancer with carcinomatosis was assessed. 34 patients (the main group) underwent colon resections, peritonectomy, omentectomy and intraperitoneal chemotherapy (mitomycin and 5-fluorouracil). 22 patients (control group) underwent palliative colon resections only. The spread of peritoneal dissemination was assessed in all patients, basing on Peritoneal Cancer Index (PCI). It was found, that the rate of postoperative morbidity is higher in the main group, but it was not accompanied by enhanced postoperative mortality. It was also detected, that cytoreductive approach permits to prolong the survival (17.0 +/- 3.5 months in main group vs. 7.5 +/- 2.1 months in controls). The main prognostic factor in these patients was the PCI. The most favorable prognosis is identified if PCI < 5 (few discrete implants are present); the survival in this group was 23.0 +/- 4.5 months and disease-free interval was 14.0 +/- 2.5 months. When PCI was higher then 5, the survival was 14.5 +/- 2.5 months and disease-free interval was 7.0 +/- 1.3 months.
