Indications and results of resection for hepatocellular carcinoma

Aim: In this retrospective series we evaluate our experience in surgical treatment of HCC and examine early and long-term results of 46 hepatic resections. Methods: Eighty-eight patients with HCC have been observed at our Department. Fifty patients (57%) have been operated, but only 46 (92%) could be resected; 43 patients (93.5%) carried liver cirrhosis. We performed 28 non-anatomical resections (60.8%) and 18 anatomical resections (39.2%). Tumour clearance at resection margin of at least 1 cm was considered for a curative resections. Results: Overall mortality and morbidity were 8.7 and 30.4% respectively. These rates significantly decreased in the last years: from 1995 to 2000 no hospital mortality has been recorded. Hospital mortality among non-anatomical and anatomical resection subgroups was 3.5 and 16.6% respectively (P<0.02). After a median f.u. of 41 months, 19 patients (45.2%) had recurrences: it was intrahepatic in 16 (84.4%). We observed a 3-, 5- and 10-years actuarial survival rate 62, 51.1 and 22.5% respectively. Long term survival significantly differed between non-anatomical and anatomical resections, with 5-year and 10-year values of 61.1 and 34.3% vs 37.7 and 18.8% respectively (P=0.0224). Conclusions: Early results after hepatic resection for HCC can be improved by using a limited surgical approach. Long-term results are still unsatisfactory, because of the high recurrence rate that is not influenced by different surgical approaches.
