Popis: Background/Aims This study aimed to study the outcome and survival of patients with large hepatocellular carcinoma (HCC) receiving drug-eluting beads (DEBs) transarterial chemoembolization (TACE). In addition, tumor morphologies were correlated with the response and survival to analyze the association of morphology with the outcome. Methods Patients with large HCC (>5 cm) who underwent DEB-TACE for palliation were analyzed retrospectively. Patients were assessed for objective response (OR) and overall survival (OS), which was calculated from the first session of DEB-TACE to the last follow-up/death. OR and OS were calculated for the entire study group and were compared among the subgroups consisting of solitary versus multifocal HCC, unilobar versus bilobar disease, well-defined versus ill-defined HCC, and HCC with homogeneous enhancement versus HCC with heterogeneous enhancement. Results Sixty-seven DEB-TACE procedures were performed in 25 patients (average: 2.7 ± 1.4 sessions per patient). The mean lesion size was 9.9 ± 4.5 cm. Of 25 patients, 13 (52%) had multifocal HCC. Unilobar disease was seen in 15 patients (60%). The mean duration of follow-up was 24.4 months. OR at 6 and 12 months were 56% and 48%, respectively, with well-defined lesions showing better OR. The median OS was 28 months (95% confidence interval, 12.3–43.6). OS rate at 12 and 24 months was 92% and 57%, respectively. OS was seen to be superior in well-defined HCC and unilobar disease. Conclusion In this study, DEB-TACE has shown to have a good response in patients having large/multifocal HCC with preserved liver functions. Well-defined HCC and unilobar disease have a better response and survival.
