Brief summary: This phase II study is to evaluate the effectiveness of hypofractionated proton beam therapy (PBT) for HCC patients in hepatitis B endemic area.

Detailed description: The primary endpoint is local progression free survival. The trial is a single arm phase II trial with the historical arm. The expected 3-year local progression free survival for patient with HCC patients treated with proton beam therapy would be 80%. With a power of 80% and a type I error level of 10%, evaluable 40 patients are required to reject that the null hypothesis that true 3-year local progression free survival rate is ≤65%. Considering the 10% unevaluable patients due to loss of follow up, a total 45 eligible patients for each arms will be enrolled.

Eligibility criteria: Inclusion Criteria:

* HCC diagnosed as (i) the presence of risk factors including hepatitis B or C virus and liver cirrhosis, a serum a-fetoprotein (AFP) level greater than 200 IU/ml and a radiologically compatible feature with HCC in one or more CT/MRI/angiograms, or (ii) the presence of risk factors including hepatitis B or C virus and liver cirrhosis, a serum a-fetoprotein (AFP) level less than 200 IU/ml, and a radiologically compatible feature with HCC in two or more CT/MRI/angiograms or (iii) histological confirmation
* HCC patients who were not prospective suitable or refused for any other treatment, such as surgery or local ablation therapy, or recurrent or residual tumor after other treatments.
* without evidence of extrahepatic metastasis
* All target tumors must be encompassable within single irradiation field (15x15 cm maximum)
* no previous treatment to target tumors by other forms of RT
* liver function of Child-Pugh class A or B7 (Child-Pugh score of ≤7)
* Age of ≥18 years
* performance status of 0 to 2 on the Eastern Cooperative Oncology Group (ECOG) score
* WBC count ≥ 2,000/mm3; hemoglobin level ≥ 7.5 g/dL; platelet count ≥ 25,000/mm3; and adequate hepatic function (total bilirubin ≤ 3.0 mg/dL; AST and ALT \< 5.0× upper limit of normal; no ascites)
* no serious comorbidities other than liver cirrhosis
* written informed consent

Exclusion Criteria:

* evidence of extrahepatic metastasis
* age \< 18 years
* liver function of Child-Pugh class B8-9 and C (Child-Pugh score of \>7)
* previous history of other forms of RT adjacent to target tumors
* poor performance status of 3 to 4 on the Eastern Cooperative Oncology Group (ECOG) score
* multicentric HCCs, except for those with the following two conditions: \*multinodular aggregating HCC that could be encompassed by single clinical target volume and within single irradiation field (15x15 cm maximum) \*lesions other than targeted tumor that were judged as controlled with prior surgery and/or local ablation therapy.
