Objective To compare the value of apparent diffusion coefficients (ADCs) of MR-DWI at different b values in evaluating the progression of hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE).Methods All of 168 patients with HCC who met the inclusion and exclusion criteria and received the TACE for the first time in the Characteristic Medical Center of PAPF were collected retrospectively, who were divided into a stable group and progressive group according to the results of MRI evaluation at the 6th month after the TACE treatment. The clinical and imaging data of the two groups were compared before the TACE treatment. The Cox proportional hazard regression model was used to analyze the risk factors for the disease progression after the TACE treatment. The receiver operating characteristic curve (ROC) was used to analyze the predicting of efficacy evaluation of TACE by the ADC values at different b values.Results Compared with the stable group, the proportions of hepatitis B cirrhosis history, portal vein tumor thrombus, and arteriovenous fistula were higher (P<0.05), and the BCLC stage and Child Pugh grade were worse (P<0.05), and the ADC values were higher (P<0.05) in the progressive group. The results of Cox analysis showed that the ADC values at b=600 and 800 s/mm2 before the TACE, history of hepatitis B cirrhosis, portal vein tumor thrombus, arteriovenous fistula, advanced BCLC stage and Child-Pugh grade were the risk factors for the progression at the 6th month after the TACE treatment. When the b value was 800 s/mm2, the ADC value had the highest efficacy in predicting the outcome of patients (area under ROC curve was 0.746), and the best diagnostic cut-off point was 1.20×10–3 mm2/s, the sensitivity was 73.3% and the specificity was 71.8%.Conclusion ADC value of MR-DWI could predict progression after TACE in patients with HCC, and ADC value of 800 s/mm2 has a better predictive value for them.
