Increasing incidence of thyroid cancer in shanghai, China, 1983-2007

Abstract

Increasing incidences of thyroid cancer were observed in some countries, like USA, UK, France, etc. Jointpoint regression was used to analyze the incidence of thyroid cancer in Shanghai, China, from 1983 to 2007. The results showed there were both two distinct slopes, in males representing a significant APC of 2.6% from 1983 to 2000 (P<0.001), followed by a sharply increased APC of 14.4% (P <0 .001), and in females representing a significant APC of 4.9% from 1983 to 2003 (P<0.001), followed by a sharply increased APC of 19.9% (P =0 .001). Incidence of thyroid cancer increased 5 to 8 years after the supplement of iodine, for males and females respectively, suggesting that either the developed screening techniques or supplement of iodine might contribute to this accelerated increase in incidence of thyroid cancer. The predicated future burdens indicated that thyroid cancer is never an unusual cancer, either in the present or in the future.
