RESULTS OF RADIOFREQUENCY THERMOABLATION AND REPEATED LIVER RESECTION IN PATIENTS WITH METASTASES OF COLORECTAL CANCER AFTER PRIMARY LIVER RESECTIONS. COMPARATIVE ANALYSIS
The aim of the study is to evaluate patients' treatment outcome with recurrent CRC liver metastases after previous resection taking into account the use of RFA. Materials and methods. Retrospective analysis of treatment outcome of 29 patients with recurrent colorectal liver metastases after previous liver resection over the period of 2005-2015 was performed. The group of patients who underwent repeated resection included 17 patients, as compared with 12 patients who underwent RFA after previously performed liver resection. Results. Postoperative complications in the group with RFA occurred in 30% of patients, 88% in the group with repeated resection and case fatality rate was 5.9%. Radical treatment was performed in 58.8% of patients. In case of recurrent radical surgery the 5-year survival rate was 50% with median survival 31.4 months. RFA in patients with previous liver resection for metastases due to CRE resulted in 5-year survival rate in 33.3% of all cases and median survival was 24.5 months. No 5-year survival rate was revealed in non-radical recurrent resection. Summary. The analysis of patient outcomes (2005-2015) with recurrence of colorectal cancer metastases to the liver after previous liver resection and RFA. Immediate results and follow-up outcomes of both methods are described in the article. The analysis of the further treatment of the patients of these groups is performed. Conclusion. RFA in patients with previous resection for CRC liver metastases is a promising means of treatment for this group of patients. RFA can be considered as an independent method of treatment and to a certain degree it can be alternative for recurrent resection. It can also be an auxiliary step in the treatment prior to repeated resection in order to stabilize somatically preoccupied patients.
