The univariate Cox regression analyses on the expression of CD3EAP and the clinicopathological characteristics of endometrial cancer patients showed that grade (HR = 3.027, P=0.015), FIGO stage (HR = 2.651, P=0.042), myometrial invasion (HR = 2.447, P=0.044), and the expression of CD3EAP (HR = 4.820, P < 0.001) are significantly correlated with the poor prognosis of patients (Figures 7(e)). This evidence concerns the gene POLR1G and endometrial cancer.
