[Preliminary efficacy and safety analysis of carrelizumab combined with apatinib in patients with middle-advanced liver cancer progressed after drug-eluting beads-transcatheter arterial chemoembolization].

Abstract

Objective: To explore the preliminary clinical efficacy and safety of calerizumab combined with apatinib in the treatment of patients with middle-advanced liver cancer whose disease has progressed after drug-eluting beads-transcatheter arterial chemoembolization (D-TACE). Methods: A retrospective analysis of 23 patients with advanced liver cancer after D-TACE who were treated with carrelizumab combined with apatinib from April 2019 to July 2020 at Lianyungang First People s Hospital was carried out. There were 15 males and 8 females with a mean age of (62±9) years. The clinical efficacy was evaluated according to the modified Response Evaluation Criteria in Solid Tumors (mRECRST), and treatment-related adverse events were analyzed after treatment. Results: All the patients received D-TACE therapy with an average of (2.6±1.0) times, TACE-refractory tumor was observed in 7 patients, and distant metastasis was seen in 6 patients. The objective response rates after combined treatment of 1 month and 3 months were 47.8% and 60.9%, respectively. Disease control rate (DCR) was 73.9% and 78.3%, respectively; median progression-free survival (mPFS) was 126 days. Among 18 patients with alpha fatoprotein (AFP)>200 μg/L, the values before and after treatment of 2 months was (497±117) μg/L and (80±19) μg/L, respectively (P<0.05). Among 9 patients of vascular endothelial growth factor (VEGF)>142.2 ng/L, the values before and after treatment of 2 months was (154±51) ng/L and (57±19) ng/L, respectively (P<0.05). The incidence of treatment-related adverse events was 87.0% (20/23). All adverse reactions did not exceed grade 3 and could be controlled by symptomatic supportive treatment or reducing the dose of apatinib,and the serum aspartate aminotransferase (AST) level after treatment of 3 months[(77±33) U/L] was higher than that before treatment [(45±26) U/L] (P<0.05). Conclusion: For patients with advanced liver cancer after D-TACE, the treatment of carrelizumab combined with apatinib is effective and the adverse reactions are controllable.
