BACKGROUND: The National Central Cancer Registry (NCCR) is a governmental organization for cancer surveillance affiliated to the Bureau of Disease Control, Ministry of Health, in China. It annually collects cancer registration data from local registries and then analyzes and publishes the results to provide useful information for making anti-cancer policy, program evaluation, and etiology research. At the end of 2012, the NCCR reported cancer statistics for 2009. METHODS: By mid 2012, 104 population-based cancer registries reported cancer incidence and mortality data, including demographic information, for 2009, to the NCCR. After an evaluation procedure, a total of 72 registries' data met the criteria, which was then compiled for analysis. Individual lung cancer cases were retrieved from the national database based on the International Classification of Diseases (ICD)-10 topography code as "C33, C34," including cancers of the trachea and bronchus. The crude incidence and mortality rates of lung cancer were calculated by gender, age, and location (urban/rural). China's population in 1982 and Segi's population structures were used for age-standardized rates. RESULTS: In cancer registration areas in 2009, lung cancer was the most common cancer in China and in urban areas, the second most common cancer in rural areas. It was the leading cause of cancer death both in males and females, urban and rural areas. The incidence and mortality rates of lung cancer were higher in males than those in females, and in urban areas than in rural areas. The age-specific incidence and mortality rates showed that both rates were relatively low for those aged under 50 years, but dramatically increased and reached a peak in the age group of 80-84 years. CONCLUSION: Lung cancer is the most common cancer in China and leading cause of cancer death. Primary and secondary prevention should be carried out in each group, such as tobacco control and early detection.
