Immediate and Remote Results of Palliative Surgery in Patients With Metastatic Colorectal Cancer

Abstract

The significance of the study is associated with the high level of the morbidity rate of colorectal cancer, generous amount of patients with the 4th stage and the necessity of the research of palliative surgical treatment. A retrospective analysis of 364 cases with metastatic colorectal cancer included 58 patients with palliative colon resection and 306 patients with bypass anastomosis and unloading stoma. Evaluated parameters are the frequency of postoperative complications, postoperative mortality rate, median survival and one-year survival. In the group of palliative resections the frequency of postoperative complications and postoperative mortality rate were 32.7% and 20.6%, in the group of symptomatic operations the same results were 12.1% and 8.8%. Median survival, one-year survival in the group of palliative resections are longer than in the group of symptomatic operations - 10.0 and 5.1 months, 37.0% and 18.3%, respectively (p < 0.05). However, after stratification of studied subgroups according to the sign of the presence or absence of post-operative chemotherapy the survival were shown to be higher in patients with chemotherapy and hardly depended on fact of the removal of the primary tumor. To our opinion the high rate of postoperative complications and the postoperative mortality rate after palliative resections of the colon can be corrected by more precise determination of indications to their performance in emergency surgery. The improvement in survival indices is associated with the execution of postoperative adjuvant chemotherapy.
