Abstract:
Objective To understand the incidence and change trend of thyroid cancer in Qingpu District， Shanghai from 2007 to 2016， and to provide a reference for formulating relevant prevention and treatment strategies.
Methods The incidence data of thyroid cancer among residents in Qingpu District from 2007 to 2016 were collected using the Shanghai Malignant Tumor Registration System， and the crude incidence rate was calculated for different gender and age groups. The age-standardized incidence rate was calculated using the world standard population， and the annual percentage change （APC） was calculated using Joinpoint software to analyze the time trend of the incidence of thyroid cancer.
Results The incidence of thyroid cancer changed from 8.97/105 in 2007 to 52.02/105 in 2016， with an increase of 479.93% （APC=23.60， P<0.05）. The standardized incidence rate of thyroid cancer in men and women was 11.21/105 and 32.11/105， respectively， Male to female incidence ratio was 1∶3. Thyroid cancer in Qingpu District was mainly concentrated in the 25‒64 age group， accounting for 88.03% of the total incidence.
Conclusion From 2007 to 2016， the incidence of thyroid cancer in Qingpu District， Shanghai has a significant upward trend. The age of high incidence tends to be younger and the incidence of women is significantly higher than that of men. Corresponding prevention and treatment measures should be formulated in consideration of the discovered incidence characteristics.
