Incidence analysis of thyroid cancer in Pudong New Area of Shanghai, 2010-2014

ObjectiveTo describe the trend for incidence of thyroid cancer (TC) in Pudong New Area of Shanghai and to provide reference for further studies and control strategies in this regard.

MethodsAnnual TC incidence data within the period of 2010-2014 for Pudong New Area was provided by Pudong CDC.Crude incidence rates, age-standardized incidence rates and percent changes (PC) were used to describe the trend for TC.

ResultsDuring 2010-2014, a total of 5 434 new cases of TC were diagnosed, and the ratio of male and female incidence was 0.35:1.In Pudong New Area, the crude incidence rate of TC was 38.83 per 100 000, the age-standardized incidence rate of TC 26.82 per 100 000, and PCs 97.36%, ranking the 7^th most common cancer incidence in male, and ranking the 2^nd most common cancer incidence in female.The incidence of TC was increasing in both male and female.Papillary cancer in TC was the dominant type with its proportion over 96.21% in total types of TC.From 2010 to 2014, its growth rate in suburban was higher than that in urban.The population with high risk of TC was gradually concentrated in the 20-69 years age group.

ConclusionTC incidence increases obviously in Pudong New Area.Therefore, its integrated control intervention should be carried out in population with high risk of TC.
