Objectives: Resection of colorectal cancer (CRC) liver metastases (LM) in pathological liver (PL) patients (with cirrhosis or hepatopathy) is extremely rare. The aim of this study was to perform a multicentre, retrospective analysis of epidemiology, surgical techniques and outcomes in patients with PL who underwent hepatic resection for CRC-LM.
Methods: A retrospective, multicentre questionnaire was distributed to 15 hepatopancreatobiliary surgical units.
Results: Only six of 15 (40%) HPB units reported any experience in the surgical resection of CRC-LM in patients with PL. Of the 20 patients identified, 10 had underlying cirrhosis and 10 had chronic hepatopathy. Their median age was 66 years (range: 49-81 years). Thirteen patients were male. Liver dysfunction was known preoperatively in 18 patients. All patients had Child-Pugh class A disease. Six patients had synchronous disease. There were a total of 38 lesions among the 20 patients, distributed at a median of one lesion per patient (range: 1-4 lesions). The median size of the lesions was 3.0 cm (range: 1.5-9.0 cm). Preoperative median carcinoembryonic antigen (CEA) was 32.3 ng/ml (range: 1-184 ng/ml). The surgical procedures performed included: sub-segmentectomy (n= 12); left lateral sectionectomy (n= 6); segmentectomy (n= 4); radiofrequency ablation (n= 3), and exploratory laparotomy (n= 4). Morbidity occurred in four patients (Clavien grades I [n= 1], II [n= 2] and IVa [n= 1]). Mortality was nil. An R0 resection margin was achieved in 15 of 16 patients. Twelve patients did not receive chemotherapy. In resected patients, 10 presented with relapse. The median disease-free and overall survival periods were 12.2 and 22.3 months, respectively.
Conclusions: When feasible, liver resection is the best option for CRC-LM in PL patients.
