晚期NSCLC患者α/β水解酶折叠蛋白5和细胞免疫指标水平表达与替雷利珠单抗靶向治疗应答的关系研究
Relationship between ABHD5 and Cellular Immune Indexes and Response to Tirelizumab Targeted Therapy in Patients with Advanced NSCLC
摘要
Abstract
Objective To investigate the effect of α/β hydrolase folded protein 5(ABHD5)and cellular immunity markers on the response to tirellizumab targeted therapy in patients with advanced non-small cell lung cancer(NSCLC).Methods A total of 123 patients with advanced NSCLC who received tiralizumab in Kailuan General Hospital from October 2020 to December 2023 were selected.The efficacy of the target lesions was evaluated 4 weeks after treatment,and the patients were divided into response group and non-response group according to the treatment effect.Quantitative real time polymerase chain reaction(RT-qPCR)was used to detect the relative expression of ABHD5 in lesion tissues.The expression level of ABHD5,immune indexes[CD4+T,CD8+T,CD4+T/CD8+T,regulatory T cell(Treg),T helper cell 17(Th17),Treg/Th17]and other clinical indexes were compared between the two groups.Multivariate logistic regression analysis of independent factors influencing response to tirelizumab targeted therapy.The predictive value of ABHD5,CD4+T and CD8+T in non-response to treatment of advanced NSCLC was analyzed by receiver operating characteristic(ROC).ABHD5 expression was correlated with CD4+T and CD8+T cells by Pearson correlation analysis.Results Among the 123 patients enrolled,90 responded to treatment and 33 did not respond.The expression of ABHD5(1.16±0.18)and the levels of CD4+T(31.52%±4.26%)and CD8+T(24.39%±1.87%)cells in the non-response group were lower than those in the response group(1.47±0.21,36.43%±4.08%,29.13%±2.15%),and the levels of Treg(7.24%±0.89%)and Th17(6.23%±1.10%)cells were higher than those in the response group(6.37%±0.91%,5.42%±0.66%),and the differences were statistically significant(t=4.725～11.200,all P<0.05).There were significant differences in tumor size,number of metastases and levels of carcinoembryonic antigen(CEA),albumin(ALB)and total bilirubin(TBIL)between the two groups,and the differences were statistically significant(t=2.969～6.523,all P<0.05).ABHD5 expression and CD4+T,CD8+T cell levels were independent protective factors affecting the response to tirelizumab targeted therapy in advanced NSCLC(Wald χ2=15.803,7.954,8.631,all P<0.05).ABHD5 predicted that the AUC of non-response to treatment of advanced NSCLC was 0.897,which was higher than that of 0.860 and 0.835 predicted by CD4+T and CD8+T cells,and the prediction sensitivity and specificity were 72.73%and 94.45%,respectively.ABHD5 expression was positively correlated with the levels of CD4+T and CD8+T cells(r=0.367,0.355,all P<0.05).Conclusion The response to tirelizumab targeted therapy in advanced NSCLC is significantly correlated with the expression of ABHD5 and the levels of CD4+T and CD8+T cells,and ABHD5 has high predictive value in the treatment of advanced NSCLC.关键词
