对美国国家癌症资料基地(NCDB)1992年的17 096例子宫内膜癌与1986年～1987年间 19245例资料行对比分析。两期子宫内膜癌总数为36 341例。结果显示,1992年子宫内膜癌各个期别所占的比例无明显变化,但分期不明确者较以前有减少(分别占15,6％对45.1％)。子宫内膜癌发生的年龄分布也无变化,1992年该病患者的中位年龄是65.8岁。在黑人和低收入阶层者中,晚期病例相对较多。患者的期别与肿瘤细胞的分化程度关系密切,如G1者中,89.9％为0～Ⅰ期,而G4(未分化癌)者中,仅37.2％为0～Ⅰ期。提示细胞分化越差,发生转移的可能性越大。在治疗方式上,手术治疗的地位日益提 The comparative analysis was made between 17 096 cases of endometrial cancer in 1992 and 19245 cases of data from 1986 to 1987 in the National Cancer Information Base (NCDB) of the United States. The total number of two endometrial cancer 36 341 cases. The results showed that in 1992 the proportion of endometrial cancer did not change significantly in all stages, but the stage is not clear than before the decrease (15.6% versus 45.1%). The age distribution of endometrial cancer also showed no change, with a median age of 65.8 years in 1992. In the black and low-income class, the relatively high number of late cases. The patient’s stage is closely related to the degree of tumor cell differentiation. For example, 89.9% of G1 patients are stage 0 to Ⅰ, while only 37.2% of G4 (undifferentiated cancer) are stage 0 to Ⅰ. Prompted the worse cell differentiation, the greater the likelihood of metastasis. In the treatment, the status of surgical treatment increasingly
