Background and aim: Systemic treatments of advanced hepatocellular carcinoma (AHCC) have offered marginal clinical benefits. Recently, Italian investigators reported that etoposide and epirubicin combination (EE) chemotherapy was highly active against AHCC, with a response rate of 39% and a median overall survival (OS) of 10 months. We report our efficacy and safety results of EE in clinical practice.
Methods: Between December 1999 and October 2005, 35 patients with AHCC and fitting the preset eligibility criteria were treated with EE. Twenty-eight patients (80%) had liver disease associated with hepatitis B virus (HBV) and 26 (74%) had a prior history of transarterial chemoembolization (TACE) using cisplatin. The EE chemotherapy consisted of epirubicin 40 mg/m(2) on day 1 and etoposide 120 mg/m(2) on days 1, 3 and 5 every 4 weeks.
Results: A total of 102 chemotherapy cycles were administered, with a median of two cycles per patient (range one to eight cycles). Two patients had a partial response and nine had stable disease, with a tumor control rate of 32% (95% CI 17-48). The median progression-free survival (PFS) was 2.1 months (95% CI 1.8-2.4) and the median OS was 6.4 months (95% CI 4.4-8.5). There was a tendency toward improved PFS in patients seronegative for HBsAg and peritoneal seeding (P = 0.06 and P = 0.054, respectively). Overall survival was significantly better in patients without HBsAg and Cancer Liver Italian Program (CLIP) score 0-1 (P = 0.024 and P = 0.033, respectively). The main toxicities were hematological events, including grade 3/4 neutropenia in 29% and febrile neutropenia in 11% of patients.
Conclusion: Treatment with EE showed minimal antitumor activity with acceptable toxicity in HBV-associated AHCC, especially in patients pretreated with TACE.
