Using transient elastography to predict hepatocellular carcinoma recurrence after radiofrequency ablation

Area of Science:

• Hepatology and Oncology
• Medical Imaging and Diagnostics
• Interventional Procedures

Background:

• Hepatocellular carcinoma (HCC) is a major global health concern.
• Radiofrequency ablation (RFA) is a common treatment for HCC.
• Assessing the risk of HCC recurrence post-RFA is crucial for patient outcomes.

Purpose of the Study:

• To evaluate the efficacy of transient elastography (TE) in predicting HCC recurrence after RFA.
• To identify predictors of early and late HCC recurrence following RFA treatment.

Main Methods:

• Retrospective analysis of 228 HCC patients treated with TE and RFA (2008-2015).
• Utilized Cox regression analysis to determine independent predictors of HCC recurrence.
• Stratified patients into early (<12 months) and late (≥12 months) recurrence groups.

Main Results:

• Liver stiffness (LS) value, liver cirrhosis, platelet count, and multiple tumors were independent predictors of HCC recurrence.
• LS value independently predicted late recurrence (≥13 kPa associated with higher risk).
• HCC recurrence was the sole predictor of overall survival.

Conclusions:

• Liver stiffness measurement using TE is a valuable tool for predicting HCC recurrence post-RFA.
• TE can aid clinicians in risk-stratifying patients and tailoring follow-up strategies.
• LS assessment offers a non-invasive method to monitor treatment effectiveness.
