在美国随着生命的延长,70岁以上乳癌妇女的比率也见增多,有统计高达19%,其治疗也有特点。Pozner报道淋巴结阴性病例中,雌激素受体(ER)阴性和阳性的五年生存率分别为13%和88%,可见乳癌的分期及其ER情况具有很大的意义。纽约哥伦比亚长老会医疗中心自1980年1月至1988年1月共收治70岁以上乳癌妇女518例,对其中随访资料完整479例进行分析,统计生存率和死亡原因,肿瘤判定为ER阳性者是指其每mg组织含ER绝对水平在5fmol以上。全组病例平均随访4.6年(2.5～10.5年)。分析结果;全组平均年龄76岁(70～95岁),
With the extension of life in the United States, the proportion of breast cancer women over the age of 70 has also increased, with statistics as high as 19%, and its treatment is also characterized. In Pozner’s negative node-negative cases, the five-year survival rates for negative and positive estrogen receptors (ERs) were 13% and 88%, respectively, indicating that stage and ER status of breast cancer are of great significance. The New York Columbia Presbyterian Medical Center has treated 518 women with breast cancer over the age of 70 from January 1980 to January 1988. The complete follow-up data of 479 cases were analyzed. The survival rate and cause of death were counted. The tumors were judged to be ER positive. It means that the absolute level of ER per mg tissue is above 5 fmol. The average follow-up of the entire group was 4.6 years (2.5 to 10.5 years). Analysis results; the average age of the entire group is 76 years old (70-95 years old),
