[An analysis of incidence mortality and survival rates of lung cancer in Beijing].

In the past 30 years the lung cancer incidence rate in the countries all over the world has been on increase. A population-based cancer registry has been set up since 1976 in Beijing. The epidemiological features of lung cancer in Beijing during 1977-1986 were analysed. The data collected show that the lung cancer incidence and mortality ranked first among cancers at all sites and had been on increase from year to year. The annual average crude incidence rate of cancer was 31.3/100000 in male during 1982-1984, the world standard rate was 33.0/100000. Incidence due to lung cancer accounted for 20.3% of all male cancer cases. The crude incidence rate was 22.8/100000. Incidence due to lung cancer accounted for 16.1% among all female cancer cases. The sex ratio of the world standard incidence rates was 1.56. The lung cancer is one of the lesser prevised cancer and the five year relative survival rate is 6.5% for both sexes in 1982-1983. The lung cancer mortality rate in Beijing urban area is compared with other countries in the world, and it is found that the female mortality rate of lung cancer in Beijing is the highest.
