A Case of Hepatocellular Carcinoma Treated by Proton Beam Therapy as 1st Choice

Although first-line treatment option for single, small sized hepatocellular carcinoma in patients with preserved liver function and good performance status is resection or ablation, sometimes these modalities cannot be applied for variable reasons. For them, alternative options such as transarterial chemoeombolization, ethanol injection, and external radiation therapy can be considered, with variable success rates. Herein, we describe 45 year-old male who presented with a single small tumor located at caudate lobe. After multi-disciplinary discussion, the patient was treated with proton beam therapy, which resulted in favorable treatment outcome.
