摘要
BackgroundRadiofrequency ablation (RFA) can be a minimally invasive therapeutic option in patients with lung metastasis from colorectal caner. We aimed to elucidate the safety and survival benefit of computed tomography (CT)-guided percutaneous RFA for lung metastasis from colorectal cancer.MethodsA total 188 lesions were ablated in 43 patients from 2005 to 2017. The clinicopathological and survival data of patients were collected retrospectively. The short- and long-term outcomes and prognostic factors were analyzed.ResultsEight patients (18.6%) had viable extrapulmonary metastasis at RFA treatment. The median number of treated lung tumors was 2, and the median maximum diameter was 12mm. Complications, such as pneumothorax, pleural effusion and subcutaneous emphysema, occurred in 24 (55.8%) patients. Although chest tube drainage for pneumothorax was needed in 6 patients (14.0%), there were no mortalities. Repeated RFA for lung recurrence after primary RFA was performed in 14 patients (32.6%). In a median follow-up of 24.3 months, the median progression-free and overall survival (OS) were 6.8 months and 52.7 months, respectively. The presence of extrapulmonary metastasis and a maximum tumors size of >15mm were independently associated with a worse disease-free survival and OS. The OS of patients who underwent repeated RFA was significantly better than that of patients who underwent RFA only once.ConclusionCT-guided percutaneous RFA for lung metastasis from colorectal cancer is a safe and effective procedure in patients not eligible for surgery, particularly for lesions smaller than 1.5cm without extrapulmonary metastasis.
