Endometrial cancer affects 2-3% of American women. It is more common in obese, postmenopausal women with diabetes, hypertension, low parity, and late menopause. The prevalence of endometrial cancer among women who present with postmenopausal bleeding varies from 1.50-90%, most textbooks report a rate of 20%. Endometrial cancer is common, and although mortality rates relatively low, there are theoretical reasons suggesting that it could become a more serious problem in the future. The decreasing use of hysterectomy may leave more women at risk for endometrial cancer in future years. In contrast to cervical cancer, no routine mass screening programs for the early detection of endometrial cancer have been organized. It is of primary importance to define risk groups when designing mass screening programs. All of the methods used by cytologists for studying endometrial changes have limitations. Cervicovaginal smears allows diagnosis of, at best, 60% to 70% of carcinomas of the endometrium. Intrauterine sampling is another possible method. It consists of direct aspiration of the uterine cavity, scraping or brushing of the mucosa or uterine washing. Any method of endometrial sampling is imperfect, even dilatation and curettage has been shown to miss endometrial carcinoma. The quality of evidence supporting screening for endometrial cancer is of a low level. The lack of an effective, inexpensive and easy-to-use sampling method is the reason for the non-existent decline in the incidence of invasive endometrial carcinoma.
子宫内膜癌影响着2%至3%的美国女性。在肥胖、绝经后患有糖尿病、高血压、低生育次数及绝经较晚的女性中更为常见。绝经后出血的女性中子宫内膜癌的患病率在1.50%至90%之间,大多数教科书报道的比例为20%。子宫内膜癌很常见,尽管死亡率相对较低,但有理论依据表明它在未来可能会成为一个更严重的问题。子宫切除术使用的减少可能会使更多女性在未来几年面临患子宫内膜癌的风险。与宫颈癌不同,尚未组织用于早期检测子宫内膜癌的常规大规模筛查项目。在设计大规模筛查项目时确定风险人群至关重要。细胞学家用于研究子宫内膜变化的所有方法都有局限性。宫颈阴道涂片最多只能诊断出60%至70%的子宫内膜癌。子宫内取样是另一种可能的方法。它包括直接抽吸子宫腔、刮取或刷取黏膜或进行子宫冲洗。任何子宫内膜取样方法都不完美,甚至刮宫术也已被证明会漏诊子宫内膜癌。支持子宫内膜癌筛查的证据质量较低。缺乏一种有效、廉价且易于使用的取样方法是浸润性子宫内膜癌发病率未下降的原因。
