Abstract：Objective To investigate the changing trend of mortalities of malignant tumors in rural and urban areas of China and their differences from 2002 to 2014, and to provide evidence for their scientific prevention and control. Methods Data were retrieved from death cause data of illness and injury in China Health Statistics Yearbook (2002-2014) published by National Health and Family Planning Commission. The data were analyzed by Excel 2007, SPSS 23.0 and JoinPoint 4.2 and standardized based on world standard population (WHO 2000-2025). Results For the malignant tumors in urban residents, lung cancer had the highest mortality, with the standardized mortality of 38.21/100,000 in 2014. The mortality of lung cancer in rural residents increased progressively in 2002-2009, showed a significant increase and reached a standardized mortality of 41.67/100,000 in 2003, and then gradually tended to be stable. The mortalities of liver cancer in urban and rural residents in 2002-2014 presented a downward tendency. The mortalities of stomach cancer and esophagus cancer were both higher in rural residents than in urban ones, while the mortalities of colorectal cancer, urinary bladder cancer and breast cancer were all lower in rural residents than in urban ones. The long-term changing trends of cervical cancer mortality were similar in rural and urban areas, and both showed an increasing tendency. Conclusions The mortalities of malignant tumors in rural and urban residents in China in 2002-2014 were significantly different. Lung cancer had the highest mortalities both in rural and urban areas. The mortalities of liver cancer, stomach cancer and esophagus cancer were higher in rural residents, while the mortalities of colorectal cancer and urinary bladder cancer were higher in urban residents. The mortality of breast cancer in urban residents remained at a high level, and the mortality of cervical cancer increased progressively. Prevention is still the emphasis of work concerning tumors, and targeted prevention strategies should be developed according to the epidemiological characteristics of tumors in rural and urban areas.
