ABSTRACT
Objective:
To study the clinical effects of portal vein embolization (PVE) with N-butyl cyanoacrylate copolymer (NBCA) and with gelatin sponge (GS) as embolization materials in patients with initially unresectable hepatocellular carcinoma (HCC).Methods:
Clinical data of 90 patients with initial unresectable HCC who underwent PVE treatment at the Third Affiliated Hospital of Naval Medical University from November 2014 to April 2020 were included. There were 77 males and 13 females, aged 48 (25, 67) years old. Patients were divided into two groups according to the embolization materials selected in PVE NBCA group ( n=60) and GS group ( n=30). Forty-eight and 18 patients finally underwent secondary hepatectomy in NBCA group (resectable NBCA group) and GS group (resectable GS group), respectively. Clinical data including future liver remnant (FLR) growth rate and secondary hepatectomy rate were analyzed. Survivals after hepatectomy was followed up by telephone, WeChat, and outpatient review.Results:
The secondary hepatectomy rate in NBCA group was higher than that in GS group [80%(48/60) vs. 60%(18/30), P=0.043]. The waiting time from primary intervention to secondary hepatectomy in resectable NBCA group was 15 (7, 96) d, which was shorter than that in resectable GS group [40 (28, 118) d, P<0.001]. The FLR growth rate of resectable NBCA group was 9.03 (1.24, 29.64) ml/d, which was faster than that in resectable GS group [3.76 (0.08, 8.03) ml/d, P<0.001]. The recurrence-free survival (RFS) rates of patients in resectable NBCA group were 69.1%, 62.0% and 44.7% at 1, 2 and 3 years after surgery, and the overall survival (OS) rates were 76.4%, 69.5% and 59.6%, respectively. The RFS rates of patients in resectable GS group were 60.6%, 48.5% and 35.4% at 1, 2 and 3 years after surgery, and the OS rates were 66.7%, 60.6% and 42.4%, respectively. There were no significant differences in RFS and OS between two groups (all P>0.05).Conclusions:
PVE with NBCA and GS as embolization material showed good efficacy in patients with initially unresectable HCC. The FLR growth rate and secondary hepatectomy rate of patients using NBCA were better than those of patients using GS.
