子宫内膜癌是最常见的妇科恶性肿瘤。发病率近年有上升倾向。根据国际癌瘤联合中心的汇编,世界各地的发病率差异很大。在美国的发病亦受种族因素的影响。子宫内膜癌可发生于任何年龄,但多见于50～60岁。诊断时的平均年龄为57岁,75%发生在绝经后。有人认为雌激素与子宫内膜癌发病有关,但机理不清。病人的类脂醇生成、激素排泄及前趋病变正在广泛研究中。当体内男性素前身和雄甾烯二酮增加,或外源性性激素快速芳香化和转化为雌酮,均被认为是发展成子宫内膜腺癌的危象。这可说明子
Endometrial cancer is the most common gynecologic malignancy. The incidence has risen in recent years. According to the compilation of the International Union of Cancer Oncology, the incidence varies widely across the world. The incidence in the United States is also affected by racial factors. Endometrial cancer can occur at any age, but more common in 50 to 60 years old. The average age at diagnosis was 57 years and 75% occurred after menopause. Some people think that estrogen and endometrial cancer incidence, but the mechanism is unclear. The patient’s lipid alcohol production, hormone excretion and pre-pathological changes are widely studied. When the anterior male body and androstenedione increases in the body, or the rapid aromatization of exogenous sex hormones and conversion to estrone, it is considered a danger of developing endometrial adenocarcinoma.
