Abstract:
OBJECTIVETo investigate the incidence and mortality rates of thyroid cancer in Zhejiang province during 2000 to 2009.
METHODSThe data of thyroid cancer were collected from six cancer registries in Zhejiang province and the incidence and mortality rates of thyroid cancer were analysed.
RESULTSThe mean annual incidence rate of thyroid cancer in Zhejiang cancer registration areas was 6.93/100 000 during 2000 to 2009, and male/female ratio was 1: 3.43. The incidence rate was 3.62/100 000 in 2000 and it increased to 11.42/100 000 in 2009, with the annual percent change (APC) of 16.32% (95% confidence interval: 12.90%-19.85%). The mean annual mortality rate of thyroid cancer was 0.27/100 000 during 2000 to 2009, and male/female ratio was 1: 1.12. The mortality showed a rising trend without a distinct fluctuation from 2000 to 2009, the APC was 2.14% (95% confidence interval: from -7.10% to 12.30%). The incidence showed a rising trend with the increase of ages after 15 years old, and peaked at 55-60 years old. The mortality was low before 54 years old, but showed a rising trend with a distinct fluctuation after 55 years old, and peaked at 85-90 years old.
CONCLUSIONThe prevention and control of risk factors for thyroid cancer in young and middle-aged people is key to decrease the incidence and mortality of thyroid cancer.
