Abstract:
Objective:To analyze the temporal trends of lung cancer incidence between age, gender (male and female) and areas (urban and rural) in Beijing during 2000-2012.
Methods:The lung cancer cases were collected by Beijing cancer registry between 2000 and 2012. We calculated the incidence and world age-standardized incidence rates (ASR) which standardized by World Segi's population. Also, the average age and median age of lung cancer incidence were calculated. The annual percent changes (APC) for the whole period, for the gender ratio and for the area ratio were evaluated with Joinpoint analysis.
Result:Totally, 81 378 new cases of lung cancer were diagnosed in 2000-2012 with the average incidence rate of 52.67/100 000. The incidence rate increased by 4.84% per year from 38.99/100 000 to 65.33/100 000, but the APC of ASR was 1.69% (P<0.001) . The ASR increased 0.54% (P=0.029) per year in urban from 29.71/100 000 to 30.55/100 000 and 3.93% (P<0.001) in rural areas from 24.02/100 000 to 35.79/100 000. The incidence ratio of urban to rural decreased from 1.24 to 0.85 (APC=-3.29%, P<0.001). The incidence ratio of male to female decreased from 1.84 to 1.69 (APC=-0.45%, P=0.019).The average age of lung cancer incidence of male and female increased from 66.27 and 66.00 to 68.97 and 69.11 (P<0.001), respectively.
Conclusion:The incidence rate of lung cancer increased slightly in urban areas but increased significantly in rural areas during 2000-2012, the area ratio trend was declined. The average age of lung cancer occurrence gradually increased, but the temporal trends varied with age group. The gender ratio decreased from 2000 to 2012.
