Aim of the study
To study clinical, laboratory and imaging features correlated with complete response (CR) to transarterial chemoembolization (TACE) in patients with unresectable hepatocellular carcinoma (HCC) through 162 patients collected in Hassan II University Hospital of Fez.

Material and methods
From January 2015 to December 2019, 162 patients diagnosed with 225 HCC were treated by TACE. Among them, 14 showed CR during the follow-up. Imaging response was evaluated using the modified Response Evaluation Criteria in Solid Tumors (mRECIST). A multivariate analysis was performed including demographic parameters, etiology, -fetoprotein (AFP) rates, hepatic function scores, imaging and TACE features. In cases with complete response and remission, follow-up duration was considered from the first to the last imaging control showing no viable tumor and eventually nodule retraction.

Results
Among the 162 patients with 225 nodules, 14 (9%) of them showed remission and 148 (91%) did not. There was no significant difference between the two groups in age, performance status (PS), AFP, nodularity, size nodule or number of TACE cures. Sex, etiology, Child-Pugh and MELD scores, location, BCLC stage and blush extinction were all found to have a significant impact on therapeutic response.

Conclusions
This study demonstrates that CR of HCC treated by TACE is strongly correlated with male sex, etiology (viral hepatitis C), location (segments VI and VII) and complete blush extinction on digital subtraction angiography (DSA). No significant correlation was found, particularly that of tumor size and segment IV (as a pejorative location).
