Abstract
Introduction: Peritoneal carcinomatosis (PK) of colorectal origin is a malignant tumour of the peritoneum caused by spreading of colorectal carcinoma (KRK) over the peritoneal surface of the abdominal cavity and its organs. PK occurs as a synchronous tumour in 15−20% of patients, and as metachronous disease in 25−50% of patients.
Methods: A group of 66 patients operated on for PK was retrospectively evaluated; 18 patients were excluded due to insufficient data. We evaluated 48 patients in total (22 men and 26 women) with mean age of 58 and 53 years, respectively; 12 patients (25%) were aged over 65 years. The patients were operated on between 2000 and 2019 using the Sugarbaker´s method of maximal cytoreduction (CRS) + HIPEC (Hyperthermic Intraoperative Peritoneal Chemotherapy). We evaluated the length, median survival, the incidence of complications and lethality in relation to the Peritoneal Carcinoma Index (PCI) and the Completeness of Cytoreduction (CC) score. The patients were divided into two subgroups according to the PCI score (0−12 and >12, respectively) and the CC score (CC 0−1 and CC 2−3, respectively).
Results: The mean survival was 26.3 months in the group with PCI up to 12 and 21.4 months in patients with PCI above 12 (p=0.02). In the group with CC 0−1 the mean survival was 27.1 months, while in the patients with the CC 2−3 it reached...
