LR-TR Viable often precedes LI-RADS diagnostic criteria for local HCC recurrence after RFA

LR-TR Viable assignment preceded LI-RADS diagnostic criteria for local recurrence in 32.8% of HCC lesions after RFA, providing a median 5.0-month lead time (IQR 4.4–13.0) and smaller lesions (1.3 vs 2.0 cm, p<0.001).

• Single-institution retrospective study of 127 patients with 136 HCC lesions and 606 post-RFA assessments.
• Among 70 lesions categorized as LR-TR Viable, 64 (91.4%) eventually met local recurrence criteria; 21 (32.8%) had not yet met criteria at initial LR-TR Viable but did so later.
• Lesions were significantly smaller at initial LR-TR Viable than at subsequent diagnostic criteria fulfillment (median 1.3 cm vs 2.0 cm, p<0.001).
