Abstract: Objective The aim of this study was to investigate the influencing factors of disease control after ultrasound-guided 125I radioactive seed implantation for patients with hepatocellular carcinoma (HCC). Methods 84 patients with HCC were admitted to our hospital betweenJuly 2017 and August 2021, and all patients received ultrasound-guided intrahepatic 125I radioactive seed implantation with particle activity of 0.6-0.8 mCi and the tumor matched peripheral dose (MPD) of 110-160 Gy. The CT or MRI scan was performed 2 months after the operation and the short-term efficacy was evaluated according to RECIST standard version 1.1. The multivariate Logistic regression analysis was applied to screen for independent factors impacting disease control (the sum of complete response, partial response and disease stable). Results The intratumorous implantation of radioactive125I seeds was successfully finished in our 84 patients with HCC; at the end of two months after surgery, the imaging showed disease control in 69 cases (82.1%), including complete remission in 15 cases (17.9%), partial remission in 47 cases (56.0%) and disease stable in 7 cases (8.3%), with disease progression in 15 cases (17.9%); the univariate Logistic regression analysis showed that the proportions of Child-Pugh class B, BCLC stage C, tumor diameter > 5 cm and the received irradiation dose of 90% target volume (D90 dose) < 110 Gy in thedisease control group were 40.0%, 43.5%, 40.9% and 28.6%, all significantly lower than 60.0%, 56.5%, 59.1% and 71.4% in the disease progression group (P<0.05); the multivariate Logistic regression analysis showed that the D90 dose was an independent factor impacting disease control in patients with HCC after ultrasound-guided radioactive125I seed implantation (OR=344.350, P<0.05). Conclusion The sufficient irradiation dose is necessary in patients with unresectable HCC receiving intratumorous radioactive125I seed implantation in order to gain therapeutic efficacy, which needs further clinical investigation.
