The aim of this study is to report our experience RFA for malignant lung tumors.Methods: From 2010 27 patientes were underwent RFA for peripheral malignant tumors: metastases (n 20), primary lung cancer (n 7). Rrange of theres dimensions were from 7 to 52 mm (mean 27 mm.). Renal cell carcinoma metastases had 4 patientes, metastases of colorectal carcinoma - 10, metastases of lung cancer - 5 and hepatocelular carcinoma - 1. Indications for RFA: inabity undergo thoracotomy (9), us alternative complition pneumonectomy after lung resections (4), necessity to save lung tissue for patients with multiple lung metastases (14). We used transcutaneus RFA in 7 cases. In 14 cases thoracoscopic detection of tumor node before RFA was used. In 6 cases RFA used during thoracotomy. Used needle electrode with test portion 30 mm., maximal power and exposition of 10 min. Mediana follow-up was 19 month (2-32).Results: No postoperative mortality. Post-operative complications were associated with pulmonury tissue inflammation (6 cases). Average hospital stay of uncomplicated patients was 3-7 days. At present no local recurrences were diagnosed. But 7 patients developed new pulmonury and hepatic metastases from 3 to 18 months after RFA and 9 patientes died from progression of oncological diseases from 6 to 26 month after RFA. Four patients have died from concomitant diseases from 1.5 and to 5 month after RFA. The median survival was 19.5 month (1.5- 30).Conclusion: RFA is a reasonable option if a lesion is unresectable or necessity tissue sparing for multiple lung resection. ER -
