abstract: 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.
