Abstract:
Objective To analyze the incidence of gallbladder cancer in Qidong City from 1993 to 2012 . Methods The clinical data of gallbladder cancer from January 1993 to December 2012 for patients with census registration in Qidong were sorted out from the cancer registration center in Qidong . Annual percent change ( APC ) models were applied to describe the annual percent changes of disease incidence and the standardized incidence trend over time.The incidence was standardized with the age structure of standard population from a national census taken in 2000 . Results A total of 493 new cases were diagnosed from 1993 to 2012 , occupying 0 .81%of new-onset malignant tumors for the same period . The crude incidence rate of gallbladder cancer was 2 .41/100 000 population and the standardized incidence thereof was 1 .42/100 000 population .Both the crude incidence and the standardized incidence thereof increased on a yearly basis from 1993 to 2012 ( APC=12 .83; APC =12 .04 ) while the annual crude incidence thereof for females increased faster than that for males ( APC=14 .51; APC=10 .60 ) . Old people aged 65 years and above were a high-risk group for gallbladder cancer , occupying 63 .49%of the incidence thereof for all ages . Conclusion The incidence of gallbladder cancer increases in Qidong , Jiangsu province of China on a yearly basis from 1993 to 2012 , with the incidence thereof for females increasing faster than that for males .
