Abstract:
OBJECTIVE To explore the characteristics and influencing factors of immune-related adverse events （irAEs） induced by tislelizumab in patients with liver cancer. METHODS A retrospective cohort of 203 liver cancer patients treated with tislelizumab in Guangxi Medical University Cancer Hospital from May 2022 to March 2024 was included. These patients were divided into an irAEs group （58 cases） and a non-irAEs group （145 cases）. Clinical data were collected and compared between the two groups. A multivariate logistic regression model was employed to analyze factors influencing the occurrence of irAEs and establish a predictive model. The receiver operator characteristic （ROC） curve was plotted to evaluate the predictive value of the model for the occurrence of irAEs. The correlation between irAEs and overall survival （OS） as well as progression free survival （PFS） in patients was analyzed using the Kaplan-Meier method. RESULTS The irAEs induced by tislelizumab in liver cancer patients were predominantly grade 1-2 （89.71%）， mainly manifesting as hematological toxicity （42.65%） and hepatotoxicity （20.59%）， and mostly occurred within 1-12 cycles after tislelizumab treatment. Compared with liver cancer patients without underlying liver diseases， those with chronic hepatitis B had a higher incidence of irAEs. Statistically significant differences were observed between the irAEs and non-irAEs groups in terms of the number of patients with a China Liver Cancer Staging （CNLC） stage ≥Ⅱ， white blood cell count， neutrophil count， systemic immune-inflammation index （SII）， and neutrophil-to-lymphocyte ratio （NLR） （P＜0.05）. Multivariate Logistic regression analysis revealed that CNLC stage ≥Ⅱ was an independent risk factor for the occurrence of irAEs （P＝0.027）. The ROC curve indicated that neutrophil count， white blood cell count， NLR， and SII all demonstrated certain predictive potential for the occurrence of irAEs （with area under the curve values of 0.614， 0.592，0.591， and 0.589， respectively）. The Kaplan-Meier survival curve showed no statistically significant differences in PFS and OS between the irAEs and non-irAEs groups， among patients with different grades of irAEs， and among irAEs patients with different CNLC stages （P＞0.05）. CONCLUSION The irAEs induced by tislelizumab in liver cancer patients are relatively mild （grade 1-2），mainly manifesting as hematological toxicity and hepatotoxicity. Liver cancer patients with concurrent chronic hepatitis B are at a higher risk of developing irAEs. CNLC stage ≥Ⅱ is an independent risk factor for irAEs induced by tislelizumab. Neutrophil count， white blood cell count， NLR， and SII have certain predictive value for the occurrence of irAEs.
