子宫内膜癌是美国最常见的妇科恶性肿瘤,发病率以9％的速度上升,每年约有36000新确诊病例。围绝经期及绝经后异常出血是内膜癌最常见症状,规范处理是进行诊断性检查。然而,绝经后出血者的内膜癌发生率约为10％。如果能够预测其特异性风险因素,则低危人群可以避免由诊断性手术所致的各种不适、风险及花费。子宫内膜癌的相关风险广为人知,Feldman等人提出年龄超过70岁、糖尿病、未产和绝经四个因素的绝经后出血妇女患内膜癌的风险估计为87％,反之,则为2.6％。为探 Endometrial cancer is the most common gynecologic malignancy in the United States, with an incidence rate of 9% and an estimated 36,000 newly diagnosed cases each year. Perimenopausal and postmenopausal bleeding is the most common endometrial cancer symptoms, normative treatment is to carry out diagnostic tests. However, the incidence of endometrial cancer in postmenopausal bleeding is about 10%. If the specific risk factors can be predicted, the low-risk population can avoid the various discomforts, risks and costs caused by diagnostic surgery. The risk associated with endometrial cancer is well known. The risk of endometrial cancer in women over 70 years of age, diabetic, non-productive and menopausal bleeding is estimated to be 87% by Feldman et al. And 2.6% by contrast. For exploration
