Radiotherapy Safety for Liver Malignancies Using Post-Treatment Imaging

NCT07346573 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 274

Last updated 2026-01-16

No results posted yet for this study

Summary

The goal of this retrospective observational study is to investigate the safety of radiation therapy for liver malignancies by analyzing data from patients who have already completed this treatment . The main questions it aims to answer are:

What is the specific radiation dose level that leads to a visible change on CT scans called a Focal Liver Reaction (FLR)? Why do some patients develop these imaging changes while others do not, based on their scan features and clinical information? Researchers will compare patients who developed FLR with those who did not to identify the factors associated with this reaction.

This study uses existing medical records and images; therefore, participants will not need to undergo any new interventions or procedures.

Conditions

  • Liver Neoplasms
  • Radiation-Induced Liver Injury

Interventions

OTHER

Clinically Delivered Radiation Therapy (e.g., SBRT/IMRT) for Liver Cancer

This is a retrospective observational study. The intervention (radiotherapy) was administered as part of standard clinical care prior to the study. Researchers are analyzing the outcomes of this previously delivered intervention.
