1977～1982年北京市城区肺癌生存分析

本文用Kaplam-Meier估计和Cox回归法从性别、年龄、诊断依据、治疗方式及生存情况等方面，对1977－1982年北京市西城、东城、崇文、宣武四个城区230万人口的肺癌例进行了生存分析。全部3005例肺癌患者的生存曲线随时间而下降；除＜40岁组外，曲线随年龄增长而平等下降；多因素筛选的结果，得到包含六个协变量的模型。年龄、病理类型、合并症、手术、放疗、对生存期有显著作用。

An Analysis of Survivals of Lung Cancer in Beijing during 1977-1982

An Survival analysis include sex, age, diagnosis bases, treatment and survival status. Of lung cancer cases during 1977-1982 in 4 districts covering a population of 2.3 million in Beijing was studied by using Kaplan-Meier and Cox regression methods. Survival curves of 3005 lung cancer cases came down alongside the time last; and came down alongside the growth of age except the age group younger than 40 years. In addition, sieved result of complex factors, the authors got a model of six covariable. The survival time was obviously effected by age, type of pathology, complication in lung, state of metastasis, operation treatment and radiotherapy.
