Comparative analysis of pre- and postmenopausal endometrial cancer in 216 patients.

Background: Endometrial carcinoma (EC) is one of the most common gynecological malignancies and has become more prevalent in recent decades. The clinical manifestations and characteristics of EC in premenopausal and postmenopausal women differ and present with distinct pathological stages and subtypes of EC. Surgery remains the principal therapeutic approach, but the postoperative prognosis is largely affected by the pathological state. Methods: A retrospective study was conducted on 216 patients with EC who were hospitalized from August 2008 to August 2019 in Wuhan Union Hospital. The patients were divided into 2 groups based on the pre- or postmenopausal occurrence of EC. The general clinical characteristics, intraoperative situation, clinicopathological data, and postoperative outcomes of the 2 groups were compared. Results: Patients with premenopausal EC had earlier menarche, a higher incidence of primary infertility and anemia, and fewer pregnancies and deliveries. Patients with postmenopausal EC were older and often had hyperlipidemia and diabetes. Additionally, patients who were postmenopausal had worse tumor pathological gradings, more severe muscular invasion, and a higher rate of lymphatic metastasis. These factors led to a higher demand for postoperative radiotherapy in patients but a lower survival rate. Conclusions: Generally, premenopausal EC differs from postmenopausal EC: the latter is more malignant and has a worse prognosis.
