Abstract
Objective To investigate the morbidity and mortality of thyroid cancer in Changzhou during 2011 -2013 and learn its distribution characteristic and regularity. Methods Thyroid cancer incidence data and death data in Changzhou during 2011-2013 were extracted from Changzhou cancer registry and the death cause surveillance and report information system of disease prevention and control centre in Changzhou. 847 new cases were reported during 2011-2013. The incidence,crude and standardized incidence,mortality,crude and standardized mortality were calculated. Results 847 new cases including 145 males and 702 females,the ratio of mortality was 1:4. 84,the ratio of crude mortality was 1:4. 82 and the difference was signifi-cant(χ2 =53. 89,P<0. 05). The morbidity of thyroid cancer in Changzhou from 2011 to 2013 showed that the crude mortality increased from 5. 57/100 000 in 2011 to 10. 23/100 000 in 2013 and the standardized incidence increased from 4. 46/100 000 to 8. 07/100 000 in 2013. Incidence rate ranked 13th in 2011,while it ranked 8th. Among females,incidence rate of thyroid cancer increased from 9. 14/100 000 in 2011 to 17. 20/100 000 in 2013 and the standardized incidence increased from 7. 30/100 000 in 2011 to 13. 30/100 000 in 2013. Incidence rate ranked 8th in 2011,while it ranked 6th. Among males,incidence rate of thyroid cancer still ranked 14th with little change in the three years. Standardized death rate was 0. 29/100 000 in 2011, 0. 23/100 000 in 2012 and 0. 29/100 000 in 2013 with little change in the three years. The death rate between males and females was1:1. 86,without significant difference(χ2 =3. 54,P>0. 05). Among the 808 cases confirmed as thyroid caner by patho-logical diagnosis,627(77. 6%)were papillary carcinoma,140(17. 3%)were follicular carcinoma,18(2. 2%)were me-dullary carcinoma,16(2. 0%)were undifferentiated carcinoma and 7(0. 9%)were other types. Conclusion Thyroid canc-er incidence is increasing sharply in Changzhou city,especially among females,while the mortality has no obvious change. The result provides reference for the government to work out the cancer preventive strategies.关键词
