Abstract:
Objective To analyze the characteristics and trend of incidence and mortality of thyroid cancer in Zhejiang Province from 2007 to 2011.Methods Data from cancer registry and death registry in Zhejiang province were used to calculate the crude incidence and mortality,age -specific incidence and mortality,China - and World -standardized incidence and mortality of thyroid cancer.Trend Chi -square test was used to analyze the trend of incidence and mortality. Results From 2007 to 2011,the reported incidence rate of thyroid cancer in Zhejiang Province was 8.37 /100,000 (China -and World -standardized incidence were 5.28 /100,000 and 6.14 /100,000 respectively).The mortality rate was 0.34 /100,000 (China -and World -standardized mortality were 0.17 /100,000 and 0.24 /100,000 respectively). The incidence and mortality were both significantly higher in females and urban residents than in males and rural residents (both P <0.01).With age increased,the mortality increased.However,the incidence increased at the beginning and then declined with a peak age of 30 -59.From 2007 to 2011,the incidence of thyroid cancer increased rapidly with a speed of 29.95% per year while the mortality did not show the similar trend.Conclusion The incidence of thyroid cancer in Zhejiang Province is growing rapidly and the relative risk factors should be taken into consideration in future researches.
