Abstract: Objective The Objectives of this study were to investigate whether the incidence of thyroid cancer is high in Pingtan comprehensive experimental area,and analyze its incidence characteristics.Methods Thyroid cancer cases with the onset date from 2013 to 2015 in Pingtan were extacted from The Fujian Cancer Incidence Reporting.The basic information and diagnostic information were verified by examining the medical records of the hospital,and non-registered cases were excluded from follow-up.The crude incidence,standard rate and cumulative rate were calculated;the incidence of thyroid cancer in different genders and ages were analyzed;the composition of different pathological types and tumors of different sizes were compared.The standardization rate of China′s population was calculated according to the standard population composition of China in 2000 and the standardization rate of the world population was calculated according to the world population composition of Segi′s.Results From 2013 to 2015,there were 881 new cases of thyroid cancer in Pingtan comprehensive experimental area;They were 205 male and 676 female.The crude incidence of thyroid cancer was 69.30/100 000 and the age-standardized rate was 65.27/100 000 by Chinese standard population;the crude incidence and age-standardized rate of males were 31.78/100 000 and 29.87/100 000,respectively;107.95/100 000 and 101.19/100 000 for female;the incidence of females was 3.18 times than that of males.The median age of onset in men and women was 46 and 47 years old,respectively.Males reached the peak of incidence in the 40-age group,and females form two peaks in the 45-age group and the 55-age group.Papillary carcinoma,follicular carcinoma,medullary carcinoma and others pathological types accounted for 96.52%,1.80%,0.60% and 1.08%,respectively.Microcarcinomas with the largest diameter ≤10 mm accounted for 77.29%.Conclusion The incidence of thyroid cancer in Pingtan comprehensive experimental area is higher than the average levels of Fujian province and the nation.Papillary carcinoma is the main type,and the proportion of microcarcinoma is relatively high.
