Abstract:
Objective To analyze the incidence of gastric cancer in Qidong , Jiangsu Province from 1993 to 2012 and analyze the harmful levels and the clinical characteristics thereof , thus providing bases of implementing the prevention , research and control measures for gastric cancer . Methods The clinical data of gastric cancer from January 1993 to December 2012 for patients with census registration in Qidong were sorted out from the cancer registration center in Qidong .The annual percent change ( APC) model was used to analyze the trend over time for the incidence of gastric cancer .The incidence was standardized by utilizing the standard population age composition based on the nationwide census in 2000 . Results A total of 8 272 new cases of gastric cancer were diagnosed in Qidong from 1993 to 2012, and the median age for these patients was 67.92(57.50-76.00).Among them, 5 269 were male cases and the median age for these male patients was 67.25(57.75-74.75);3 003 were female cases and the median age for these female patients was 69.16(57.00-77.91).The annual average for the crude incidence rate of gastric cancer was 40.37/100 000, and the standardized incidence rate thereof was 25.22.37/100 000.The crude incidence rate of gastric cancer decreased significantly from 1993 to 2002(for the crude incidence rate thereof , APC=-1.59, t=-4.6, P<0.01);the crude incidence rate of gastric cancer increased significantly from 2002 to 2007(for the crude incidence rate thereof , APC=-8.88, t=-5.3, P<0.01).Both the standardized incidence rate of gastric cancer and the crude incidence rate thereof had the same trend for the period from 1993 to 2002 as well as the period from 2002 to 2007.The crude incidence rate of gastric cancer rose with the growth of ages(for male patients, APC=734.8, t=-511.2, P<0.01; for female patients, APC=43.6, t=17.9, P<0.01).The crude incidence rate of gastric cancer reached a climax for both males and females of the age group between 75 and 80. Conclusion The incidence of gastric cancer was relatively high in Qidong from 1993 to 2012;the male and the old-aged groups are high-risk groups .
