OBJECTIVE: To analyze the trend of incidence and mortality on thyroid cancer in China. METHODS: Data from 32 cancer registry sites in China was collected and Jionpoint model was used to obtain the crude, age-specified incidence and mortality, both Chinese national and world age-standardized rates of incidence and mortality and their trends. RESULTS: The crude incidence of thyroid cancer was 4.44/10(5), and the Chinese national and world age-standardized rates were 2.89/10(5) and 3.31/10(5) respectively. The crude mortality of thyroid cancer was 0.44/10(5), with the Chinese national and world age-standardized rates as 0.21/10(5) and 0.29/10(5) during 2003 - 2007 in the country. Thyroid cancer accounted for 1.67% and 0.26% of the Chinese national and world age-standardized proportions, for total cancers. Both incidence and mortality of thyroid cancer were higher in females than in males, 3.38 and 1.75 times higher in urban areas than those in rural areas. The incidence of thyroid cancer showed annually increase of 14.51% while the mortality had an increase of 1.42%. CONCLUSION: The incidence and mortality of thyroid cancer increased rapidly in China, calling for more control efforts on this disease.
