ObjectiveTo explore and analyse the prevalence of thyroid cancer among population of Jing′an District, Shanghai, providing a scientific basis for prevention and intervention.

MethodsAnalysis was made on the prevalence of thyroid cancer in Jing′an District in 2014 and its incidence and death trend from 2009 to 2014 based on the data of Shanghai Cancer Registration and Reporting System.

ResultsFrom 2005 to 2014, the total number of thyroid cancer cases in Jing′an District were 2 430, ranking fourth of all malignant tumors.The crude incidence rate of thyroid cancer was 24.33/100 000, the standardized incidence rate was 16.67/100 000.The ratio of male to female was 0.34 : 1;the difference in incidence between male and female was significant(χ²=579.77, P < 0.01).In different age groups the difference in incidence was also statistically significant(χ²=419.90, P < 0.01).The highest incidence was in 45-64 years old group, followed by 15-44 years old group. Only 155 deaths occurred; the ratio of death to morbidity was 1 : 15.68.Standardized incidence of thyroid cancer was increasing in Jing′an District from 2005 to 2014(trend Chi-square tests, χ²=7.33, P < 0.01).APC was 20.69%(male 23.81%, female 19.44%).The standardized mortality rate from 2005 to 2014 was at a relatively low level, and the trend of change was not statistically significant.

ConclusionThe government and society should pay high attention to the status of high detection rate and low mortality rate of thyroid cancer.The focus of prevention and control is rational diagnosis and treatment for a large number of thyroid cancer patients.
