Objective: To evaluate the incidence and mortality status of thyroid cancer in China, 2013. Methods: Incidence and mortality data of thyroid cancer were derived from 255 population-based cancer registries in China. Age-specific and age standardized incidence and mortality rates of thyroid cancer in different areas (urban and rural) with different gender were calculated based on the stratification of area (urban and rural), gender, age and tumor position. Chinese census in 2000 and the world Segi's population were used for age-standardized incidence/mortality rates. The incident cases and deaths were estimated using age-specific rates and national population data in 2013. Results: The estimates of new cancer incident cases and deaths were 143.9 thousand and 6 500, respectively. The crude incidence rate was 10.58/100 000 (Male 5.12/100 000, Female 16.32/100 000). Age-standardized incidence rates by Chinese standard population (ASIRC, 2000) and by world standard population (ASIRW) were 8.82/100 000 and 7.67/100 000, respectively. Male to female ratio was 1∶3.2. The crude incidence rate in urban and rural areas were 15.03/100 000 and 5.41/100 000, respectively. After adjustment by China standard population, the rate in urban areas was 2.57 times higher than that of rural areas. The crude mortality rate of thyroid cancer was 0.48/100 000 (Male 0.33/100 000, Female 0.63/100 000). Age-standardized mortality rates by Chinese standard population (ASIRC, 2000) and by world standard population (ASIRW) were 0.33/100 000 and 0.32/100 000, respectively. The crude mortality rate in urban and rural areas were 0.57/100 000 and 0.38/100 000, respectively. After adjustment by China standard population, the rate in urban areas was 1.41 times higher than that of rural areas. The cumulative incidence and mortality rates (0-74 years old) were 0.74% and 0.03%, respectively. According to the data from 255 cancer registries, papillary carcinoma is the main pathology type, which accounted for 89.9% of all malignant tumors. Conclusions: The disease burden of thyroid cancer in urban areas is higher than that in rural areas. Females have the higher incidence rate than that of males. The reasons related to the higher incidence rate of thyroid cancer should be further investigated to provide evidence for appropriate cancer control strategies and policies to be made in China.
目的： 估计2013年中国甲状腺癌的发病与死亡情况。 方法： 利用2016年全国255个肿瘤登记处提供的肿瘤发病、死亡数据，按地区(城乡)、性别、年龄、肿瘤部位分层，分别计算中国甲状腺癌地区别(城市和农村)、性别、年龄别发病率、年龄别死亡率、标化发病率、标化死亡率，年龄标化采用2000年全国人口普查的人口结构和国际Segi标准人口结构。结合2013年全国人口数据，估计全国甲状腺癌发病和死亡情况。 结果： 2013年全国甲状腺癌新发病例数估计为14.39万例，死亡病例0.65万例。全国甲状腺癌发病率为10.58/10万(其中男性为5.12/10万，女性为16.32/10万)，中标发病率为8.82/10万，世标发病率为7.67/10万，男女发病率之比为1∶3.2。全国城市和农村地区的甲状腺癌发病率分别为15.03/10万和5.41/10万，城市地区的中标发病率为农村地区的2.57倍。全国甲状腺癌死亡率为0.48/10万(其中男性0.33/10万，女性0.63/10万)，中标死亡率为0.33/10万，世标死亡率为0.32/10万。全国城市和农村地区的甲状腺癌死亡率分别为0.57/10万和0.38/10万，城市地区的中标死亡率为农村地区的1.41倍。中国甲状腺癌0～74岁累积发病率和死亡率分别为0.74%和0.03%。255个登记处提供的肿瘤发病数据显示，甲状腺乳头状癌是甲状腺癌最主要的病理类型，占89.9 %。 结论： 中国城市地区甲状腺癌的发病负担高于农村地区，女性发病率高于男性，应进一步探索甲状腺癌高发原因，为制订相关防控策略提供依据。.
