Résumé
To investigate the role of CT-texture analysis of liver ablation area to predict local recurrence after HCC ablation. Patients treated with liver ablation were retrospectively enrolled. CT-texture analysis was performed on the core and borders of ablation area 1-2 months after procedure. Tumors were grouped according to the onset of local recurrence at follow-up (persistence, recurrence-free, short- or long-term recurrence). Differences in texture parameters and which parameters were predictive of recurrence risk were assessed using a Cox regression model. 151 HCCs were treated in 98 patients (72 ± 9 years, 83 men). 68 HCCs reported no disease recurrence, 32 persistent disease, 19 short-term and 32 long-term recurrence. Median follow-up was 280 [IQR: 156-569] days. Venous phase (Ven) CT texture analysis of ablation area performed at 1-2 months follow-up could estimate the risk of local recurrence of hepatocellular carcinoma treated by radiofrequency ablation.
