Purpose. The association between transarterial chemoembolization- (TACE-) induced HCC tumor necrosis measured by the\nmodified Response Evaluation Criteria In Solid Tumors (mRECIST) and patient survival is poorly defined. We hypothesize\nthat survival will be superior in HCC patients with increased TACE-induced tumor necrosis. Materials and Methods. TACE\ninterventionswere retrospectively reviewed. Tumor response was quantified via dichotomized (responders and nonresponders) and\nthe four defined mRECIST categories. Results. Median survival following TACE was significantly greater in responders compared\nto nonresponders (20.8 months versus 14.9 months,
