Copmparative analysis of short-term and long-term effects of radiofrequency thermoablation and atypical lung resection in treatment of metastatic colorectal cancer

Treatment outcomes in patients with lung metastases from colorectal cancer were analyzed. Patients of the study group (n=48) underwent radiofrequency thermoablation (RFTA) and patients of the control group (n=55) underwent atypical lung resection. Length of surgery was on the average 44,47 ± 14,26 minutes for RFTA and 70,27 ± 19,89 minutes for atypical resection (р=0,000), and intraoperative hemorrhage was 68,54 ± 16,10 ml and 137,27 ± 36,79 ml, respectively (р=0000). The rate of postoperative complications was significantly higher in patients who underwent atypical lung resection than in patients who underwent RFTA (18,8 % versus 4,17 %, p=0,03). No significant difference in 5-year survival rate between two groups of patients was found. Within the first year, life quality of patients estimated according to FACT-G и FACT-L scales was significantly higher in patients after RFTA than in patients after atypical resection
