Background/aims: Most hepatocellular carcinomas are still discovered at an advanced stage and are left untreated as large hepatocellular carcinomas are contraindications to liver transplantation and percutaneous ethanol injection and are usually considered as poor indications for liver resection. The aim of this study was to reassess the results of surgery in these patients.
Methods: Between 1984 and 1996, 256 patients underwent resection of biopsy-proven, non-fibrolamellar hepatocellular carcinoma. Of these, 121 had a tumour diameter of less than 5 cm (small hepatocellular carcinomas) and 94 a tumour diameter of more than 8 cm (large hepatocellular carcinomas). The short- and long-term outcome of patients with small and large hepatocellular carcinomas were compared.
Results: The in-hospital mortality rate following resection of small and large hepatocellular carcinomas was comparable (11.5 vs. 10.6%), even after stratifying for the presence and severity of an underlying liver disease. In patients with a chronic liver disease, large hepatocellular carcinomas were associated with a greater risk of death and recurrence during the first 2 operative years. In the long term, however (3-5 years), survival and disease-free survival following resection of small and large hepatocellular carcinomas were comparable (34 vs. 31% and 25 vs. 21% at 5 years). Similarly, treatment of and survival after the onset of recurrence were not influenced by the size of the initial tumour.
Conclusions: Patients with large hepatocellular carcinomas should not be abandoned and should be considered for liver resection as this treatment may be associated with an in-hospital mortality rate and a long-term survival comparable to that observed after resection of small hepatocellular carcinomas.
