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

Condition or disease Intervention/treatment Phase
Hepatocellular Carcinoma Radiation: Proton Beam Therapy Not Applicable

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 will be enrolled.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 45 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II Study Using Hypofractionated Proton Beam Radiotherapy for Inoperable Hepatocellular Carcinoma
Study Start Date : March 5, 2015
Estimated Primary Completion Date : January 31, 2020
Estimated Study Completion Date : January 31, 2020

Arm Intervention/treatment
Experimental: Proton Beam Therapy

Definition of target volume:

  • Gross tumor volume (GTV) = gross tumor defined using a treatment planning CT scan
  • Clinical target volume (CTV) = GTV + internal target volume
  • Planning target volume (PTV) = CTV + 5 - 7 mm of lateral, craniocaudal, and anteroposterior margins.

Radiation dose and planning

  • Prescription dose to PTV: 70 GyE /10 fx, 7GyE fraction dose, 5 days/week
  • Dose prescription : 95% isodose volume of prescribed dose encompassed PTV
Radiation: Proton Beam Therapy

Definition of target volume:

Criteria

Inclusion Criteria:

  • Hepatocellular Carcinoma 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
  • Inoperable HCC or refusal to surgery
  • Recurrent/residual tumor after other local treatments (local ablation therapy, or transarterial chemoemobolization, etc), or unsuitable/refusal to other treatments.
  • Patients without evidence of extrahepatic metastasis
  • The largest diameter of tumor should be less than 7cm, and the number of tumor ≤2
  • The targeted tumors is more than 2cm away from the alimentary tract (i.e., stomach, duodenum, esophagus, small and large bowel)
  • 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 1 on the Eastern Cooperative Oncology Group (ECOG) score
  • Required Entry Laboratory Parameters WBC count ≥ 1,500/mm3; hemoglobin level ≥ 7.5 g/dL; platelet count ≥ 30,000/mm3; and adequate hepatic function (total bilirubin ≤ 3.0 mg/dL; AST and ALT < 5.0× upper limit of normal; no uncontrolled ascites
  • No serious comorbidities other than liver cirrhosis
  • Signed informed consent form prior to study entry

Exclusion Criteria:

  • There is evidence of extrahepatic metastasis.
