Abstract:To retrospectively analyze the clinical data of endometrial cancer in young patients, and study the expressions of ER, PR and p53 in the cancer tissues, in the order to know the clinical significance. Methods A total of 424 cases of endometrial carcinoma were divided into two groups by age of 45 years. Their clinical and pathological data were retrospectively analyzed, and the incidence of endometrial cancer in the young patients and prognostic factors were studied. Results There were significant differences in the gravidity and parity history, the presence of complications or not, the histological grade, the depth of myometrial invasion and the positive rates of PR and p53 between the patients ≥45 years of age and those <45 years of age (p < 0.05). In the endometrial cancer patients <45 years of age, ER and PR expressions were negatively correlated with age; p53 expression was positively correlated with histological grade (r = 0.289,p < 0.05) but negatively correlated with depth of myometrial invasion (r = -0.345,p < 0.05). Conclusions Endometrial cancer monitoring and health management should be strengthened in young patients with endometrial cancer. Higher expressions of ER and PR in young patients with endometrial carcinoma provide evidence for the feasibility of hormone therapy. In young patients with endometrial cancer, p53 expression is low; positive expression of p53 is correlated with histological grade and depth of myometrial invasion, therefore, p53 can be used as an index of prognosis.
