Abstract:
Objective:To identify tumor-infiltrating immune cells that affect the prognosis of endometrial cancer(EC)with no specific molecular profile(NSMP)subtypeand to establish an integrated prognostic model based on immune cells.Methods:Gene expression data,whole exome sequencing data,and corresponding clinical infor-mation for EC patients were obtained from the The Cancer Genome Atlas(TCGA)database.The CIBERSORTx algorithm was used to evaluate the infiltration levels of 22 types of immune cells in the tumor microenvironment.Kaplan-Meier survival analysis,along with univariate and multivariate Cox regression analyses were used to identi-fy immune cells with prognostic values.A prognostic nomogram was subsequently developed based on significant immune cells and clinicopathological parameters.Results:A total of 169 EC patients classified as NSMP subtype-swere included in this study.Among them 123 patients(72.8%)were aged<70 years,and 152 patients(89.9%)had type Ⅰ tumors.Kaplan-Meier curves showed that the proportion of plasma cells(P<0.001),M1 macrophages(P=0.038)and activated NK cells(P=0.01)were significantly associated with overall survival.Multivariate Cox regression analysis revealed that the proportion of activated NK cells(proportion ≥0.027:HR 0.23,95%CI 0.08-0.66,P=0.006),age(≥70 years:HR4.59,95%CI 1.80-11.70,P=0.001)and tumor stage(stage Ⅱ:HR3.87,95%CI 1.18-12.70,P=0.026;stage Ⅲ:HR 6.08,95%CI 1.69-21.87,P=0.006;Ⅳ stage:HR 10.81,95%CI 3.07-38.08,P<0.001)are independent prognostic indicators for NSMP tumors.A nomogram model was estab-lished by combining activation of NK cells,tumor stage and patient age.Internal cross-validation showed that the integrated prognostic model exhibited good predictive ability for the overall survival rates of patients(P<0.001).Conclusions:Elevated tumor-infiltrating activated NK cells serve as an independent prognostic indicator for NSMP-subtype EC patients.When integrated with tumor stage and age,they form a robust multivariable prognos-tic model with superior predictive power.
