Liver imaging algorithm predicts success of SBRT in hepatocellular carcinoma

Key clinical point: The Liver Imaging Reporting and Data System (LI-RADS) treatment response algorithm (TRA) effectively predicted tumor necrosis in patients treated for HCC with SBRT.

Major finding: The sensitivity was 71%-86% and specificity was 85%-96% for incomplete tumor necrosis of lesions treated with SBRT when the LR-TR Equivocal category was nonviable. When the LR-TR Equivocal category was viable, sensitivity was 88%-96% and specificity was

Study details: The data come from a retrospective study of 40 lesions treated with Stereotactic Body Radiation Therapy (SBRT) in 26 adult patients with HCC.

Disclosures: The study received no outside funding. The researchers had no financial conflicts to disclose.
