Safety and efficacy of sorafenib in Japanese patients with hepatocellular carcinoma in clinical practice: a subgroup analysis of GIDEON

Abstract

Background

GIDEON was a prospective, global, non-interventional study evaluating the safety of sorafenib in patients with unresectable hepatocellular carcinoma in real-world practice. The aim of this subgroup analysis was to assess the safety and efficacy of sorafenib as used by Japanese patients.

Methods

In Japan, 508 patients were valid for safety analysis. Efficacy and safety were evaluated by the Child-Pugh score.

Results

The number of patients with Child-Pugh A and B was 432 (85.0 %) and 58 (11.4 %), respectively. The median overall survival time and time to progression in patients with Child-Pugh A and Child-Pugh B were 17.4 and 4.9 months, 3.7 and 2.3 months, respectively. The most common drug-related adverse events (AEs) included hand-foot skin reaction (47.8 %), diarrhea (35.8 %) and hypertension (24.2 %). The incidences of all or drug-related AEs were similar between patients with Child-Pugh A and B. However, all or drug-related serious AEs, AEs resulting in permanent discontinuation of sorafenib and deaths were observed more frequently in patients with Child-Pugh B compared with Child-Pugh A. Duration of treatment tended to be shorter as the Child-Pugh score worsened.

Conclusions

Sorafenib was well tolerated by Japanese HCC patients in clinical settings. Patients with Child-Pugh B had shorter duration of treatment and higher incidence of SAEs. It is important to carefully evaluate patients' conditions and assess the benefit and risk before making a decision to treat patients with sorafenib.
