Analysis of 1120 cases of thyroid cancer with thyroid disease / 重庆医学

ABSTRACT

Objective To investigate the clinical changing trend and CT imaging diagnosis of thyroid cancer associated with thy-roid disease .Methods 1 120 cases of thyroid cancer patients admitted in our hospital in the past 10 years were selected and devided into different groups according to their admission timespatients admitted before 2003 were in one group;from 2003 on ,patients were divided into groups according to their admission time by a time span of 2 years ;then the changing trend and CT imaging diag-nosis of thyroid carcinoma with nodular goiter (NG) ,thyroid adenoma (TA) and merger trend of Hashimoto′sthyroiditis (HT ) of different times were compared and analyzed .Results There were 518 cases of papillary carcinoma(46 .25% ) ,345 cases of follicular adenocarcinoma ,(30 .80% ) ,158 cases of medullary carcinoma (14 .11% ) ,99 cases of undifferentiated carcinoma (8 .84% ) in 1120 patients .The occurrence rate of thyroid carcinoma with nodular goiter (NG) in 2009-2010 ,2011-2012 and the occurrence rate of thyroid carcinoma with HT in 2007-2008 ,2009-2010 ,2011-2012 were significantly higher than that of 2005-2006 (P<0 .05) . Take 2007-2008 as the deviding line of thyroid combined TA ,and it shows that the occurrence rate increased continuously before this line and started to drop down after that .CT of thyroid cancer shows uneven low-density imaging ,blur edge ,and inhomogeneous enhancement .The CT characteristics differ from different diseases .Conclusion In recent years the incidence rates of thyroid with nodular thyroid and HT increased significantly compared with the years before ,while incidence rate of TA decreased .
