Using the Chinese Census in 2000 and the World Segi′s population as the standard population, the age-standardized incidence rate by Chinese standard population (ASIRC) and by world standard population (ASIRW) were 24.11/100 000 and 20.65/100 000 respectively. 256 TC death cases reported in all, the crude mortality rate was 0.44/100 000, the age-standardized mortality rate by Chinese standard population (ASMRC) and by World standard population (ASMRW) were 0.23/100 000 and 0.23/100 000 respectively. The ASIRC had a upward trend [annual percent change (APC)=28.62%, 95%CI 21.00%-36.72%, t=13.10, P=0.001], while the ASMRC trend seemed stable (APC=0.73%, 95%CI -7.47%-9.66%, t=0.27, P=0.803).
