ABSTRACT
Objectives: To analyze lung cancer data of patients who are registered in Zhejiang province from 2010 to 2014 and describe the prevalence and mortality of lung cancer in residents of Zhejiang province, so as to provide a reference basis for the government and health administrative departments to formulate a strategy of cancer prevention and treatment. Methods: According to the report of 14 tumor registries of Zhejiang province from 2010 to 2014 in urban and rural areas, lung cancer incidence and mortality were calculated by gender, age, and urban or rural areas, respectively. The population structure from the 2000 national census and Segi's standard population was used to calculate the standardized rates and indicators such as the 0-74-year-old accumulation rates and 35-64-year-old truncation rates. Results: In 2010-2014, there were 37,227 new cases of malignant tumors of the trachea, bronchi, and lungs in Zhejiang cancer registration areas (which are referred to as lung cancer in this article; ICD10 was coded as c33-c34), with the crude incidence rates of 63.55 per 100,000, 35.73 per 100,000 for ASR China, and 35.54 per 100,000 for ASR world, accounting for 18.85% of all cancer cases. The cu-mulative rate of incidence in those aged 0-74 years was 4.44%. Of the new cases, 25,608 were men and 11,619 were women. The ASR China in male was as 2.26 times high as that in female. The ASR China in rural areas was as 1.12 times high as that in urban areas. There were 31,772 deaths in 2010-2014, with the crude mortality rates of 54.24 per 100,000, 29.39 per 100,000 for ASR China, and 29.05 per 100,000 for ASR world, accounting for 29.22% of all cancer deaths. Of the deaths, 22,796 were men and 8,976 were women. The ASR China in male was as 2.70 times high as that in female. The ASR China in rural areas was as 1.05 times high as that in urban areas. The age-specific incidence and mortality rates were relatively low before 40 years old, and increased dramatically after 40 years old, then reached peak at the age of 80 years old. Rates in male were generally higher than those in female. The age-specific incidence and mortality rates varied in urban and rural areas with similar curves. Conclusions: Lung cancer was the most common malignancy in Zhejiang province, and its incidence and mortality are both in the first place of all cancers . With the relatively high burden of disease, lung cancer should be regarded as one of the key malignant tumors while developing strategies for cancer prevention and treatment.
