Abstract:
BACKGROUND:The immune cell composition and functional states within the tumor microenvironment of epithelial ovarian cancer directly influence patient prognosis and therapeutic response.Recent studies indicate that CD4+T cells not only support anti-tumor immunity but can also exert direct anti-tumor effects under specific conditions.High infiltration of CD8+T cells is considered a positive prognostic marker.FOXP3+regulatory T cells play a crucial role in maintaining immune tolerance and modulating immune responses.OBJECTIVE:The data from 416 epithelial ovarian cancer patients along with clinical pathology samples from 21 patients were comprehensively analyzed utilizing bioinformatics algorithms to investigate the relationship between the expression of CD4+T cells,CD8+T cells,and FOXP3+T cells in the tumor microenvironment and survival outcomes in ovarian cancer patients.METHODS:(1)The study categorized 416 cases of epithelial ovarian cancer from the Ovarian Cancer subset of The Cancer Genome Atlas using the Non-negative Matrix Factorization algorithm.The CIBERSORT algorithm(Cell-type Identification By Estimating Relative Subsets Of RNA Transcripts)was employed to examine differences in immune cell infiltration between patients with high and low survival rates.(2)Multiplex immunohistochemistry was used to assess the expression of CD4,CD8,and FOXP3 in pathological tissue samples from 21 patients from Chinese People's Liberation Army General Hospital,and their association with patient prognosis was analyzed.RESULTS AND CONCLUSION:The high survival rate group exhibited significantly greater infiltration of immune cells,including CD4+T cells,CD8+T cells,and FOXP3+regulatory T cells,compared with the low survival rate group(P＜0.01).Results from the multiplex immunohistochemistry experiments revealed that high expression of FOXP3 was significantly correlated with better prognosis in ovarian cancer patients(P＜0.05).It is indicated that the expression of FOXP3 in the tumor microenvironment is associated with survival outcomes in epithelial ovarian cancer patients,suggesting that the infiltration of FOXP3+regulatory T cells in the tumor microenvironment is a key factor influencing patient prognosis.
