Incidence rate of lung cancer in urban Shijiazhuang in 2012 with prevention implication

Abstract

BackgroundPollution has been established as an environmental factor in the development of lung cancer; however, the incidence rate in Shijiazhuang, one of China's most heavily polluted cities, is unknown.MethodsAs Chinese citizens are entitled to complete public medical insurance coverage, we estimated the lung cancer incidence rate among registered citizens of urban Shijiazhuang in 2012 using reimbursement records of first hospitalization.ResultsIn Shijiazhuang, lung cancer was the most common cancer in men and the second most common cancer in women. The age standardized world incidence rate (ASRW) was 46.42 and 19.14/100 000, respectively, compared with 51.05 and 22.24/100 000, respectively, reported for 63 Chinese tumor registration cities in 2010 (the national level). However, age‐specific rates for the 55–70 range in men and the 25–55 range in women were higher in Shijiazhuang than nationally. Compared with GLOBOCAN 2012 data, the lung cancer ASRW in Shijiazhuang was comparable to that of all industrialized countries (44.7 and 19.6/100 000), but higher than all developing countries (30.0 and 11.1/100 000), Japan (38.8 and 12.9/100 000), and Korea (45.5 and 16.2/100 000).ConclusionThe lung cancer incidence rate in Shijiazhuang matched the world's highest level in 2012. According to the experience of western countries, the incidence rate in China is expected to continue to rise over the next 40 years. Intervention is urgently required in order to reduce smoking prevalence by a third by 2025 and to take concrete legal action to reduce air pollution.

Incidence rate of female breast cancer in urban Shijiazhuang in 2012 and modifiable risk factors

“…As reported previously, the female age distribution of the 2000 Chinese national population survey was used to calculate the age‐standardized rate for China (ASRC), and the Segi standard world population (modified by Doll) was used to calculate the age‐standardized rate of the world (ASRW) . Using age‐standardized breast cancer incidence rates, urban Shijiazhuang was compared with 31 other Chinese tumor registration cities (2009 data), GLOBOCAN 2012 data, and the Yangpu and Gusu Districts of Suzhou City .…”
