Purpose: The present retrospective study aimed to evaluate the efficacy and safety of camrelizumab addition to transarterial chemoembolization (TACE) in the treatment of hepatocellular carcinoma (HCC) with TACE-related untreatable progression (UP). Methods: Patients with HCC who received addition of camrelizumab due to UP after initial TACE treatment were enrolled at our institution between May 2019 and January 2021. Patients were assessed for tumor response, progression-free survival (PFS), and adverse events (AEs). Risk factors for PFS were evaluated with logistic regression analysis. Results: A total of 41 patients were included. The objective response rates (ORR) and disease control rates (DCR) were 24.4% and 61.0% at 2 to 3 months, and 12.2% and 58.5% at 6 months, respectively. The median PFS of the patients were 6 months (95% confidence interval [CI]: 3.8 months, 8.2 months). Of the 41 patients, 23 received camrelizumab combined with TACE (hereafter, camrelizumab-TACE) on whom 52 combined TACE procedures were performed, with a median of 2 procedures (range: 1-6) per patient. The remaining 18 patients received camrelizumab alone due to TACE contraindications. Multivariable analysis indicated that camrelizumab-TACE was an independent prognostic factor for PFS. Subgroup analysis showed a median PFS of 8 months in the camrelizumab-TACE group and 3 months in the camrelizumab monotherapy group (P < .001). No treatment-related mortalities occurred. Seventeen patients (41.5%) developed at least 1 type of AE after treatment with camrelizumab, with reactive cutaneous capillary endothelial proliferation (RCCEP) (n = 14, 34.1%) being the most common AE. Conclusion: Addition of camrelizumab to TACE offered an effective and safe treatment for HCC with UP.
