EXPERIENCE OF SURGICAL TREATMENT OF COLORECTAL CANCER WITH LIVER METASTASES

Abstract

AIM. To compare results surgery ofcolorectal cancer with resection or radiofrequency thermoablation of liver metastasesi. MATERIALS AND METHODS. Fifty seven patients were included into study. In first group (n=24) liver resection was performed simultaneously with primary tumor surgery; in the second group (n=33) patients underwent local thermal destruction of metastases. RESULTS. Postoperative complications developed in 2 (8,3%) patients of group I and 4 (12,1%) in group II. In group II, the postoperative in-hospital mortality rate was 5,8% (2 patients) due to failure of colonic anastomosis withfecal peritonitis. The disease-free period in group I was 14,4±3,2 months. The 3-year survival rate was 39%, with the median survival of 32,5 months. In group II, the 3-year survival rate was 27%. CONCLUSION. Resectable liver metastases should undergo resection, if there are no adverse factors. This study shows that liver resection is a more effective treatment than radiofrequency thermoablation.
