Popis: AIM To investigate the role of intraoperative local ablation techniques (LATs) in bilobar colorectal liver metastases (bCRLM). PATIENTS AND METHODS Among patients who underwent LAT for CRLM between 2005 and 2015, we selected 33 patients with bilobar disease submitted to thermal ablation alone or associated to liver resection. Primary end-point was complete local response at one month (CLR). Secondary end-points were morbidity, mortality, disease-free survival (DFS), local tumor recurrence (LTR) and long-term survival. RESULTS CLR was observed in 100% of cases, while LTR occurred in 8 cases (22%). DFS at 1, 3 and 5 years was 37%, 5% and 5%. Overall survival (OS), in the same interval, was 95%, 49% and 26%. Univariate analysis found a significant correlation between LTR and tumor size (11% ≤20 mm vs. 50% >20 mm; p=0.009). CONCLUSION LAT is an effective adjuvant strategy in bCRLM for nodules within 20 mm diameter.
