Abstract

Introduction. This study aimed to present the results of the first experiences in thermal ablation of colorectal cancer lung metastases in Poland. 

Material and methods. Seven patients with colorectal cancer lung metastases were treated with CT-guided microwave ablation. One of them was lost to follow-up, so 6 patients with 7 metastatic foci were included in this study. The mean diameter of lesions was 15 mm (10–20 mm). The patients were disqualified from surgical treatment due to comorbidities. 

Results. The mean duration of follow-up was 15 months (range: 6–29). No mortality was noted during that period. Local progression was not reported, while distant progression was found in two patients. Two patients presented with pneumothorax just after the ablation, and one of them required chest tube drainage. No complications were noted. 

Conclusions. Patients with a few small colorectal cancer lung metastases can benefit from thermal ablation. The method is safe and should be available for medically inoperable patients with pulmonary oligometastatic disease.
