Abstract:
Objective To analyze the incidence of colorectal cancer ( CRC) for patients with census registration in Qidong , Jiangsu Province . Methods The clinical data of CRC for patients with census registration in Qidong were sorted out from the cancer registration center in Qidong , Jiangsu province .The incidence was standardized by utilizing the standard population age composition based on the nationwide census in 2000 .The annual percent change ( APC) model was used to analyze the trend over time for the incidence of CRC . Results A total of 4 648 new cases of CRC were diagnosed in Qidong from 1993 to 2012 , of which 2 328 were male cases and 2 320 were female cases .The crude incidence rate for CRC was 23 .00/100 000 and the APC for the standardized incidence rate for CRC was 14 .13/100 000 , with the incidence thereof for males significantly higher than that for females ( P<0.001).The incidence rate of CRC for seniors aged over 50 rose quickly .From 1993 to 2012 , the average annual increase rate of the incidence for CRC was 5 .1%and the average annual increase rate of the standardized incidence therefor was 5.0%in Qidong. Conclusion The incidence of CRC increases in Qidong on a yearly basis from 1993 to 2012 , with the incidence thereof for males being significantly higher than that for females .
