Hepatocellular Carcinoma With Different Areas of Right Retroperitoneal Space Invasion: Evaluation of Transcatheter Arterial Chemoembolization Efficacy and Blood Supply Characteristics

The clinical efficiency of TACE combined with simultaneous computed tomography-guided radiofrequency ablation for advanced hepatocellular carcinoma

Background To investigate the clinical efficiency of transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) for advanced hepatocellular carcinoma (HCC). Methods This retrospective study enrolled 177 HCC patients, and they were divided into TACE monotherapy group (n = 129) and TACE + RFA group (n = 48) between January 2015 and October 2017. The objective response rate (ORR), disease control rate (DCR), and the survival outcomes were compared between the TACE monotherapy and the treatment of TACE + RFA after propensity score matching (PSM). Results After PSM matching, the confounding factors had no significant differences between the 48 pairs of patients. The DCR was calculated as 33 (69 %) and 42 (88 %) for the TACE monotherapy group and TACE + RFA group, respectively (P < 0.05). And the ORR was calculated as 23 (48 %) and 35 (73 %), respectively (P < 0.05). Moreover, the PFS rate of the TACE + RFA group was significantly higher than the TACE alone group (P < 0.001). Conclusions The treatment of TACE combined with RFA has better tumor response rate and survival rate than the TACE monotherapy for patients with advanced HCC.
