Primary Outcome Measures:
  • Tumor measure rates [ Time Frame: 6 months ]
    Tumor size will be measured every 2 months following treatment to assess for shrinkage, stability of size, or increasing size. Adverse events will also be monitored every 2 months to assess for safety.

Secondary Outcome Measures:
  • assessment of plasma biomarkers for liver function [ Time Frame: 6 months ]
    Collect data on plasma biomarkers of liver function to plan further enhancements to individualized SBRT

Enrollment: 90
Study Start Date: October 2009
Estimated Study Completion Date: November 2016
Primary Completion Date: November 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Liver cancer patients
The aim of this study is to determine the safety and effectiveness of individualized Stereotactic Body Radiation Therapy (SBRT) in patients who either (1) have had previous liver treatments, and/or (2) have primary hepatocellular carcinoma (HCC).
Radiation: individualized Stereotactic Body Radiation Therapy (SBRT)
The individualized SBRT involves two treatment phases. The first phase of treatment involves receiving three fractions of SBRT, followed by a 1-month break and assessment of liver function with a blood test - Indocyanine Green (IC-Green). The second phase of treatment involves receiving two more fractions of SBRT, whose doses are adjusted to account for tolerance of the first phase of treatment.

Detailed Description:
The trial endpoints are toxicity, survival and progression-free survival. DCE-MRI and plasma biomarkers will also be collected to explore their use as tools for treatment individualization in future trials. During the current trial, an indicator of liver function, indocyanine green (ICG), will be used to identify during treatment patients who are at excess risk for radiation-induced liver disease (RILD) so that their radiation dose may be reduced. The model used for individualization will be updated as trial data accrue, so this is an adaptive trial of an individualized therapy. The planned accrual is seventy (70) evaluable patients over three years.
