Abstract: Objective To evaluate the efficacy of CD8+ T lymphocytes in immunotherapy in patients with advanced hepatocellular carcinoma.Methods A total of 89 patients with advanced hepatocellular carcinoma admitted to the hospital from March 2019 to July 2022 were selected. All patients received immunotherapy. According to clinical efficacy, patients were divided into effective group (partial response (PR) and complete response (CR)) and ineffective group (disease progression (PD) and stable disease (SD)). The level of CD8+ T lymphocytes in the 2 groups and the clinical data in the 2 groups were compared. The influencing factors of immunotherapy ineffectiveness in patients with advanced hepatocellular carcinoma was analyzed. The predictive value of CD8+ T lymphocytes in patients with advanced hepatocellular carcinoma was analyzed. Results After treatment, SD, PD, PR and CR of the 89 patients were 8, 24, 57 and 0, respectively. The objective response rate (ORR) was 64.04% (57/89), with 32 cases in the ineffective group and 57 cases in the effective group The level of CD8+ T lymphocytes in effective group was higher than that in ineffective group (P<0.05). The ECOG score > 0, Child-Pugh classification was B grade, Barcelona stage (BCLC) was end-stage, poorly differentiated, extrahepatic metastasis, and alpha-fetoprotein (AFP) ≥20 ng/mL of proportion of cases in effective group was higher than that in the effective group (P<0.05). Child-Pugh grade B, end-stage BCLC, and AFP and CD8+ T lymphocyte levels were influential factors for immunotherapy efficacy in patients with advanced hepatocellular carcinoma (P<0.05). Receiver operating characteristic curve (ROC) curve showed that the area under curve (AUC) value of CD8+ T lymphocyte level in predicting immune response in advanced hepatocellular carcinoma patients was 0.781 (P<0.05). Conclusion CD8+ T lymphocyte level can be used to predict the efficacy of immunotherapy in patients with advanced hepatocellular carcinoma, and low CD8+ T lymphocyte level of patients have a greater risk of treatment failure.
