Analysis on incidence and mortality of colorectal cancer in Chongqing municipality,2015
Objective:To understand the incidence and mortality of colorectal cancer in Chongqing and to provide the suggestion for colorectal cancer prevention and control. Methods:Colorectal cancer cases(ICD-10 code:C18-C21)from 11 cancer registration sites were collected and sorted by the international category of disease(ICD-10)and the international category of tumor(ICD-O-3). The data were analyzed to calculate the incidence
mortality and age-specific standardized incidence rate and mortality rate by Chinese standard population(ASIRC/ASMRC)and World standard population(ASIRW/ASMRW)and proportion by SPSS 19.0. The difference of the incidence and mortality of colorectal cancer between the male and female
urban and rural area was compared by Chi-square test. The trend of colorectal cancer with age was analyzed by trend Chi-square test(α =0.05). Results:The incidence of colorectal cancer ranked the second of all cancers in 2015 in Chongqing
which accounted for 10.51% of all cancers. The incidence
ASIRC
ASIRW of colorectal cancer was 28.32/105
17.57/105 and 19.32/105 respectively in 2015. The incidence of colorectal cancer among male residents(32.80/105)was higher than that among female residents(23.74/105)significantly(χ
2
=8.572
P=0.003). The truncated rate of age 35-64
cumulative rate and cumulative risk of colorectal cancer incidence were 25.77/105
2.10% and 2.08% respectively.The mortality
ASMRC and ASMRW of colorectal cancer were 13.95/105
8.02/105 and 9.33/105 respectively in 2015. The mortality of colorectal cancer among male residents was higher than that among female residents significantly(χ
2
=9.410
P=0.002). The mortality of colorectal cancer in urban area was higher than that in rural area significantly(χ
2
=6.378
P=0.012). The truncated rate of age 35-64
cumulative rate and cumulative risk of colorectal cancer mortality were 9.38/105
0.89% and 0.88% respectively. The incidence and mortality of colorectal cancer increased significantly with the age(χ
2
=14.533
P=0.000;χ
2
=11.398
P=0.001). The incidence of colorectal cancer increased rapidly after 40 years old and its mortality increased rapidly after 50 years old. Conclusion:The incidence and mortality of colorectal cancer is high in Chongqing municipality. Great importance should be attached to tertiary prevention for colorectal cancer.
