Abstract:
Objective To analyze the detection rate of thyroid cancer from 2009 to 2013 in Shaoxing of Zhejiang province and its time trend.Methods The data of thvroid cancer in Shaoxing from 2009 to 2013 was collected to calculate the detection rate,age adjusted detection rate and percentage change of incidence,and the annual percentage change (APC) of incidence was estimated by linear regression based on the logarithm of the incidence rates observed.Results lDuring 2009-2013,a total of 3 290 new cases were diagnosed as thyroid cancer with the sex ratio of male to female being 1 ∶ 3.69.The detection rate of thyroid cancer was 14.98/100 000 (male 6.39/100 000,female 23.59/100 000),with age-standardized detection rate by Chinese standard population (ASR China)9.13/100 000(male 3.94/100 000,female 14.31/100 000),and age-standardized detection rate by world standard population(ASR worll) 10.39/100 000(male 4.47/100 000,female 16.32/100 000).The detection rate of thyroid cancer increased from 7.26/100 000 in 2009 to 27.26/100 000 (APC =39.65％,P＜0.05),with the detection rate among males increasing from 2.42/100 000 to 12.65/100 000(APC =48.44％,P＜0.05),and the detection rate among female increasing from 12.15/100 000 to 41.96/100 000(APC =37.58c％,P＜0.05).In Shaoxing,most of the new thyroid cancer cases were from 25 to 59 years old,and the highest incidence happened in the group of 50-54 years.For each age group,the detection rate in female was almost over two-folls higher than the incidence in male.Conclusion The detection rate of thyroid cancer was increased year by year from 2009 to 2013 in Shaoxing,especially among the young and middle-aged women.The corresponding measures must be taken to control the risk factors of thyroid cancer.
