Sorafenib as first-line treatment for patients with primary hepatocellular carcinoma: an outcome evaluation

OBJECTIVE: To evaluate the clinical outcomes following first-line treatment with sorafenib in patients with primary hepatocellular carcinoma (HCC). METHODS: This retrospective cohort study enrolled patients with primary HCC that had been treated with sorafenib. Their data were collected from the hospital medical records database at three time-points: after three cycles, after six cycles and at the end of the sorafenib treatment regimen. The starting dose was 800 mg/day sorafenib but this could be reduced to 600 mg/day or 400 mg/day if patients developed adverse events (AEs). RESULTS: A total of 98 patients participated in the study. Of these, nine (9.2%) had a partial response, 47 patients (48.0%) had stable disease and 42 patients (42.9%) had progressive disease. The overall disease control rate was 57.1% (56 of 98 patients). Median progression-free survival for the overall cohort was 4.7 months. The most common AEs were hand-foot skin reaction (49 of 98 patients; 50.0%), fatigue (41 of 98 patients; 41.8%), appetite loss (39 of 98 patients; 39.8%) and hepatotoxicity/transaminitis (24 of 98 patients; 24.5%). The majority of the AEs were toxicity grades 1 and 2. CONCLUSION: Sorafenib as a first-line treatment for primary HCC patients provided survival benefits and the AEs were well tolerated by patients.
