Moreover, through univariate and multivariate Cox regression analyses, we identified clinical stage, primary therapy outcome, histological type, residual tumor, and EXO1 expression levels as independent risk factors for PFI in UCEC, M stage, and EXO1 expression level as independent risk factors for PFI in THCA, and N stage, M stage, and EXO1 expression levels as independent risk factors for DSS in BRCA. Here, EXO1 is linked to neoplasm.
