[Abstract]
Objective To investigate traditional Chinese medicine (TCM) syndrome characteristics associated with immunotherapy efficacy in cervical cancer using propensity score matching (PSM), aiming to identify the population benefiting from immunotherapy. Methods A retrospective analysis was conducted in 253 cervical cancer patients, who received the treatment with programmed death receptor 1(PD-1) inhibitors at Guang’anmen Hospital,China Academy of Chinese Medical Sciences from January 2020 to October 2024. Clinical data and TCM four-examination data were collected. After balancing the confounders via PSM(1∶1 matching) and with therapeutic efficacy as the dependent variable,multivariate logistic regression was performed to analyze the characteristics of TCM syndrome in the immunotherapy-response group and then a predictive model was constructed. Results (1)After matching with PSM,198 cases were included,99 cases in response group and 99 cases in non-response group. (2)Analysis of the distribution of TCM syndrome elements showed that the differences in the pathogenic syndrome elements of qi deficiency,qi stagnation,blood stasis,heat and phlegm between the two groups were statistically significant (P<0.05 or P<0.01),while there were no statistically significant differences in the disease-location syndrome elements of uterus,kidneys,lungs,spleen,liver,and heart,as well as in the pathogenic syndrome elements of blood deficiency, yin deficiency, yang deficiency, cold, and dampness (P>0.05). The main pathogenic syndrome elements in the response group were qi deficiency,blood deficiency and heat,while those in the non-response group were qi stagnation, heat and phlegm.(3) The results of univariate regression analysis showed that targeted therapy (P = 0.040), programmed cell death-ligand 1(PD-L1) expression level (P< 0.001),qi deficiency (P = 0.009),blood deficiency (P<0.001),yang deficiency (P<0.001),yin deficiency (P<0.001),qi stagnation (P = 0.003),blood stasis (P<0.001),cold (P<0.001),cold (P<0.001),heat (P<0.001),phlegm (P<0.001),and dampness (P<0.001) were the factors associated with the efficacy of PD-1 inhibitors. (4) The results of multivariate logistic regression analysis showed that previous targeted therapy (OR= 0.36,95% CI:0.16-0.83) and pathogenic syndrome elements of qi stagnation (OR=0.23,95%CI:0.10- 0.49), phlegm (OR=0.28,95%CI:0.13-0.61) were the risk factors of associated with the efficacy of PD-1 inhibitors, while PD-L1 expression level (OR=15.27, 95%CI: 2.60-89.63), and pathogenic syndrome element qi deficiency (OR=2.90, 95%CI: 1.42-5.89) were the protective factors associated with the efficacy of PD-1 inhibitors in cervical cancer.(5) Receiver operating characteristic (ROC) curve analysis demonstrated that the area under the ROC curve (AUC) of the predictive model for evaluating PD-1 inhibitor efficacy in cervical cancer was 0.78(95%CI:0.71-0.84),indicating certain predictive value. Conclusion PD-L1 expression level and TCM pathogenic syndrome elements such as qi deficiency,qi stagnation, and phlegm are the independent factors influencing PD-1 inhibitor efficacy in cervical cancer,providing insights for optimizing integrated TCM-western medicine treatment strategies.
