Abstract:
Objective:To study the use of radioactive I-125 seed implantation in the treatment of transarterial chemoembolization (TACE)-refractory hepatocellular carcinoma (HCC).Methods:A retrospective study was conducted on 70 patients with HCC who were initially treated with TACE between July 1, 2016 and August 31, 2019 at the Second Affiliated Hospital of Guangzhou Medical University. After these patients were found to be refractory to TACE, 29 patients were converted to radioactive I-125 seed implantation (the 125I seed group), and 41 patients were continued with TACE (the TACE group). The objective response rate, progression-free survival (PFS), overall survival (OS), total overall survival (TOS) of the two groups were compared. Results:There were 59 males and 11 females, aged (60.5±11.9 ) years in this study. At 1, 3, 6 months after treatment, the objective response rates of the 125I seed group were 20.7%, 40.7%, 34.6%, respectively, which were significantly higher than that of the TACE group of 2.6%, 3.3%, 5.0%, respectively. The PFS, OS, TOS in the 125I seed group were 7.6, 21.1, 32.1 months, respectively, which were significantly better when compared with the TACE group (3.5, 8.5, 14.8 months, respectively, all P<0.05). There was no significant difference in the embolization syndrome between the two groups [93.1%(27/29) vs 100.0%(41/41), P>0.05]. Child-Pugh B grading ( HR=0.311, 95% CI: 0.160-0.603, P=0.005) and TACE ( HR=0.308, 95% CI: 0.159-0.597, P=0.002) were independent risk prognostic factors for survival. Conclusion:This study showed better treatment efficacy and safety using radioactive I-125 seed implantation in TACE-refractory HCC and this treatment significantly improved survival of patients when compared with TACE alone.
