Objective:To understand the incidence and trend of cervix carcinoma in Chongqing and to provide the suggestion for cervix carcinoma prevention and control. Methods:Cases of cervix carcinoma from 2006 to 2014 were collected from cancer registered sites in Chongqing. The indicators of cervix carcinoma such as incidence

age-standardized incidence by China and World

annual percent change(APC)

truncated rate of the age group 35-64

cumulative rate and cumulative risk were calculated. The significant of the trend change of cervix carcinoma from 2006 to 2014 was identified by curve estimated exponential distribution regression model.Results:The sequence of cervix carcinoma in Chongqing increased from the sixth to the fourth from 2006 to 2014. The incidence

aged standardized incidence by China and World increased from 7.99/100 000

8.52/100 000

9.48/100 000 in 2006 to 14.82/100 000

11.98/100 000

12.89/100 000 in 2014 significantly(F value:18.32

8.38 and 7.40

R2 value:0.72

P<0.05). Its APC was 7.47%

4.19%

3.77% respectively. The incidence of cervix carcinoma in urban area was higher than that in rural area. The incidence

aged standardized incidence by China and World increased from 4.53/100 000

4.98/100 000

5.54/100 000 in 2006 to 13.62/100 000

12.84/100 000

13.82/100 000 in 2014 significantly(F value:41.88

79.57 and 68.09

R2 value:0.86

0.92 and 0.91

P<0.001). And its APC was 17.70%

13.20%

12.75% respectively. The incidence of cervix carcinoma increased after 30 years old and reached the top at the age group of 50 years old. The truncated rate of the age group 35-64

cumulative rate and cumulative risk increased from15.77/100 000

0.12%

0.12% in 2006 to 25.01/100 000

0.21% and 0.21% in 2014 significantly in Chongqing(F value:28.47

13.57 and 13.57

R2 Value:0.80

0.66 and 0.66

P<0.05). Conclusion:The incidence of cervix carcinoma increased in Chongqing. And it increased fast in rural area. It should be enhanced tertiary prevention for cervix carcinoma.
