Objective. To analyze the menstrual characteristics of endometrial carcinoma and investigate whether abnormal uterine bleeding in the perimenopausal period differs from postmenopausal bleeding. Methods. We conducted a retrospective analysis of 928 cases of endometrial carcinoma in patients admitted from January 2016 to December 2022. We gathered fundamental clinical data and analyzed distinct clinical risk factors between the perimenopausal and postmenopausal groups. Furthermore, we computed the statistical variances in menarche, regular menstrual cycles, and the duration of abnormal uterine bleeding. Results. Perimenopausal patients with endometrial carcinoma exhibit similar factors to postmenopausal patients, especially if they have a history of menstrual cycles lasting more than 30 years, hypertension, abnormal uterine bleeding for over 1 year, and a high risk of endometrial carcinoma. Early intervention for abnormal uterine bleeding during the perimenopausal stage can prevent up to 80% of women from developing endometrial carcinoma. Conclusion. Perimenopause women experiencing abnormal uterine bleeding should be mindful of the risk of endometrial carcinoma, as this awareness can substantially decrease the occurrence of the disease.

客观的。分析子宫内膜癌的月经特征，探讨围绝经期异常子宫出血与绝经后出血是否不同。方法。我们对 2016 年 1 月至 2022 年 12 月收治的 928 例子宫内膜癌患者进行了回顾性分析。我们收集了基本临床数据，并分析了围绝经期组和绝经后组之间不同的临床危险因素。此外，我们还计算了初潮、规律月经周期和异常子宫出血持续时间的统计方差。结果。围绝经期子宫内膜癌患者与绝经后患者表现出相似的因素，尤其是有月经周期持续30年以上、高血压、异常子宫出血1年以上、子宫内膜癌高危人群。围绝经期期间异常子宫出血的早期干预可以预防高达 80% 的女性患子宫内膜癌。结论。经历异常子宫出血的围绝经期女性应注意子宫内膜癌的风险，因为这种认识可以大大减少该疾病的发生。
