title: Increasing incidence of thyroid cancer in Shanghai, China, 1983-2007.
abstract: Increasing incidence of thyroid cancer has been observed in some countries such as the United States, United Kingdom, France, and so on. Joinpoint regression was used to analyze the incidence of thyroid cancer in Shanghai, China, from 1983 to 2007. The results showed that there were 2 distinct slopes: in men, representing a significant annual percentage change (APC) of 2.6% from 1983 to 2000 (P < .001) followed by a sharp APC of 14.4% (P < .001), and in women, representing a significant APC of 4.9% from 1983 to 2003 (P < .001) followed by a sharp APC of 19.9% (P = .001). The sharp increase in thyroid cancer occurred 5 and 8 years after the iodine supplementation by salt, for men and women, respectively, suggesting that either the developed screening techniques or iodine supplementation might have contributed to the rapid increase in the incidence of thyroid cancer. The burden of thyroid cancer cases is expected to be substantial, based on predictions through 2020.
