北京市城区居民癌症患者生存率分析

目的：了解北京市地区癌症患者生存情况，为评价肿瘤诊治效果提供数据。方法：利用北京肿瘤登记处20世纪80年代所积累的肿瘤登记报告病例和随访资料，采用经曲寿命表法进行肿瘤生存率分析。结果：北京城区居民主要恶性肿瘤中，5年相对生存率最高的为女性乳腺癌（74．2％），其次为结直肠癌（39．8－44．1％），生存率较低的肿瘤是肺癌，食管癌（11．8－13．9％），预后最差的是肝癌（3．4％－5．3％），1982年－1983年与1987年－1988年两个时期的比较，各种主要肿瘤的生存率均有不同程度的提高。结论：北京市各种不同部位肿瘤患者中，除女性乳腺癌外，主要恶性肿瘤生存率普遍降低，但随着医疗诊治技术的改进，癌症患者的生成期不断在改善。

Cancer Survival in Urban Beijing

Purpose] Cancer survival during 1982～1983 and 1987～1988 is analyzed to evaluate the level of cacner diagnosis and treatment in Beijing. Method] Population-based cancer registration data were used. Method of life table was applied. Results ] The five year relative survival rate (RSR) for female breast cancer during 1987 ～ 1988 was on the top (74.2 % )among all sites. The 5-year RSR for eoloreetal cancer was the second (39.8%～44.1% ), and the lung cancer and esophageal cancer, were 11.8%～13.9% .The RSR of the liver ancer was the lowest(3.4%～5.3% ) .The survival rates for all sites of the cancers in 1987～1988, compared with that in 1982～1983, increased obviously. Conclusion] Cancer survival rates of cancers, except for breast cancer,were rather poor. But it appears an improving tendency with the development of diagnosis and treatment technology.
