Transarterial chemoembolization (TACE) is a primary therapeutic approach aimed at prolonging survival or serving as a link to liver transplantation.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Objective:<\/jats:bold>\n                    To identify factors associated with the response to TACE by modified Response Evaluation Criteria in Solid Tumors (mRECIST) in patients with HCC.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Materials and Methods:<\/jats:bold>\n                    This is a retrospective cohort study conducted at a Liver Institute in Brazil, including patients with HCC at Stages A and B treated with TACE from January 2011 to December 2021. Data were collected from electronic or digitized physical medical records and included demographic, clinical\u2013laboratory, and tumor\u2010related variables. Radiological response was assessed using mRECIST criteria.
