Epidemiology and outcome of hepatocellular carcinoma in Lombardy

Abstract

Background and aims Information on the impact of therapeutic strategies of hepatocellular carcinoma is still incomplete due to the lack of surveys involving primary-care centres. Patients and methods The Gruppo Epatologico Lombardo (GEL) carried out a study on 361 incident hepatocellular carcinoma observed from January to December 1998 in 22 hospitals in Lombardy. The clinical, pathological and therapeutic data were collected from all patients; 5-year survival and factors related to outcome were analysed. Results Two hundred and ninety-seven patients were male (M/F: 4.6/1, mean age 66); 61% were HCV-pos, 15% HBV-pos, 17% alcoholic. Cirrhosis was present in 333 (92%) and was classified as Child-A in 197 (59%), Child-B in 85 (26%) and Child-C in 51 (15%) cases. Hepatocellular carcinoma was multifocal/diffuse (more than three nodules) in 91 (25%), less than three nodules in 86 (24%) and monofocal in 184 (51%) (≤3 cm in 146). As to the therapy: 145 hepatocellular carcinomas (40%) were untreated, 78 (22%) underwent percutaneous ethanol injection/radiofrequency ablation, 75 (20%) transarterial chemoembolization, 32 (9%) liver resection and 3 (0.8%) ortothopic liver transplantation (OLT). Survivals at 1, 3 and 5 years were 75%, 27% and 13%, respectively. Child-Pugh score, small size of the tumour and treatment, regardless of the type, were independent predictors of better prognosis. Conclusion This prospective, region-wide, cohort study showed that the characteristics of hepatocellular carcinoma in Lombardy (1998) do not differ from those reported in previous Italian surveys. Although most hepatocellular carcinomas were discovered at a relatively early stage, a large part remained untreated and the overall prognosis was poor. Efforts are warranted to implement screening-surveillance programmes and the impact of therapeutic strategies.
