Abstract: Objective · To analyze the clinical and pathological characteristics of endometrial carcinoma patients before and after menopause.  Methods · Fifty-two premenopausal cases and 150 postmenopausal cases with endometrial carcinoma from December 2013 to March 2017 in Ruijin Hospital, Shanghai Jiao Tong University School of Medicine were retrospectively analyzed.   Results · The ratio of patients with hypertension in premenopausal group was 28.8%, which was significantly lower than that in postmenopausal group (P<0.01). In premenopausal group, the proportion of G3 in histological grading was 8.3%, and the ratio of deep myometrial invasion was 13.5%, all of which were significantly lower than those of postmenopausal group (P<0.05). The ratio of ovarian involvement was as high as 17.6%, which was significantly higher than that of postmenopausal group (P<0.05). There were no significant differences between the two groups in other clinical-pathological parameters such as obesity, diabetes, CA125, CA199, surgical-pathological staging, pathological type, vascular involvement, and lymph node metastasis.  Conclusion · Premenopausal endometrial carcinoma is less malignant, while the probability of ovarian involvement is higher.
