Abstract: Objective To investigate the incidence and mortality of lung cancer from 2011 through 2013 among residents covered by a cancer registry system in Jiangxi province, and to provide evidences for prevention and control of lung cancer.Methods The data on lung cancer incidence and mortality from 2011 through 2013 were collected from 6 cancer registration areas in the province.Crude incidence and mortality, age-standardized incidence and mortality rate by Chinese standard population(ASR China) and by world standard population(ASR world), cumulative incidence and mortality rate, truncated incidence and mortality rate, potential years of life loss(PYLL), potential years of life loss rate(PYLLR), and average years of life lost(AYLL) were calculated, respectively.Results The crude incidence of lung cancer in the registration areas during the period was 43.08/10⁵(61.96/10⁵ for male and 23.33/10⁵ for female);the incidences of ASR China and ASR world were 26.48/10⁵ and 35.88/10⁵;and the cumulative incidence rate(0-74 years) was 4.47%.The crude mortality rate was 27.98/10⁵(40.64/10⁵ for male and 14.74/10⁵ for female);the mortalities of ASR China and ASR world were 16.54/10⁵ and 22.67/10⁵;and the cumulative mortality rate (0-74 years) was 2.77%.The incidence and mortality of lung cancer increased with age and were higher in the males than in the females.The PYLL and AYLL of lung cancer were 14 199 person-years (10 471 person-years for male and 3 728 person-years for female) and 8.26 years(8.20 years for male and 8.42 years for female).Conclusion The incidence and mortality of lung cancer in registration areas in Jiangxi province are lower than those of national level.Males and the elderly are the key populations for the prevention and treatment of lung cancer and the early deaths due to lung cancer among the females needs to be concerned.
