Radiation-induced liver disease (RILD) is a syndrome characterized by the development of anicteric ascites approximately 2 weeks to 4 months after hepatic irradiation. Previous studies have shown that both the volume of liver irradiated and the dose of radiation delivered are prominent factors for development of RILD. While use of a population-based normal tissue complication probability model allows investigators to limit the risk of RILD to a clinically acceptable level, a test that permits investigators to determine an individual's risk of RILD during the course of treatment may allow for individualized treatment modifications, either to prevent toxicity or increase efficacy.

Condition Intervention
Hepatocellular Carcinoma

Further study details as provided by University of Michigan Cancer Center:

Primary Outcome Measures:
  • Changes in hepatobiliary single photon emission tomography (SPECT) after radiation therapy [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Changes in SPECT, which reflect hepatocyte function, will be correlated with specific regions of radiation dose to determine a relationship between dose and radiation-induced damage.

Secondary Outcome Measures:
  • measuring values between regional radiation dose and local hepatic function as measured by hepatobiliary SPECT, in normal liver parenchyma [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    dynamic hepatobiliary single photon emission tomography (SPECT) values will assess changes in hepatocyte function in patients with intrahepatic malignancies receiving radiation therapy. Perhaps a relationship between SPECT and dosage can be determined.

Estimated Enrollment: 20
Study Start Date: August 2008
Estimated Study Completion Date: January 2016
Estimated Primary Completion Date: January 2015 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Liver Irradiation
patients already scheduled to undergo liver irradiation
Radiation: Liver Irradiation
Patients already scheduled to undergo radiation treatment

Detailed Description:

Early, but subclinical physiologic changes in the liver may be associated with the future development of RILD. There are currently limited data on how a local change in hepatic function associates with regional radiation dose, and how the change of hepatic function during and after radiation therapy (RT) associates with RILD. In the present study, a radiological methodology that is minimally invasive will be used to measure volumetric hepatic functions in patients with intrahepatic malignancies before, during, and after a course of fractioned radiation therapy.
