Background & AimsThe current study analysed the association between radiologic tumour response and survival times of patients with hepatocellular carcinoma (HCC) who were treated with transcatheter hepatic arterial chemoembolization (TACE). MethodsAmong 493 consecutive patients presenting to our institution between July 2002 and June 2010 with radiologically (n=398) or histologically (n=95) confirmed HCC, 368 patients who met inclusion criteria, underwent TACE and had confirmed survival data were retrospectively reviewed. The radiologic response was assessed using RECIST 1.1, EASL and mRECIST criteria at 1month after the initial TACE. ResultsBy univariate analysis, higher Child-Turcotte-Pugh (CTP) score, bilobar and multifocal distribution of tumours, larger tumour size (>5cm), higher serum alpha-foetoprotein (AFP) level (>200ng/ml), no subsequent radiofrequency ablation, advanced ECOG, UNOS and BCLC staging, absence of complete necrosis and non-responder (SD or PD) in RECIST 1.1, EASL and mRECIST response assessment were significantly associated with shorter overall survival times. By Cox proportional hazards model, advanced age, presence of ascites, higher MELD score, advanced BCLC staging, absence of complete necrosis and non-responder by RECIST 1.1, EASL and mRECIST criteria were independent and significant prognosticators for overall survival times in patients with HCC who underwent TACE. By time-dependent ROC curve analysis, mRECIST response criteria showed greatest accuracy in predicting survival (AUROC=0.8676), followed by EASL (AUROC=0.8471) and RECIST 1.1 (AUROC=0.7986). ConclusionmRECIST and EASL criteria for assessing radiologic response 1month after initial TACE more consistently predict the differences in overall survival between responders and non-responders than conventional RECIST 1.1 criteria.
