ABSTRACT
Objective At present,the detection rate of cervical metastatic lymph nodes in patients with papillary thyroid carcinoma (PTC) is relatively low by imaging technology.The article aimed to demonstrate the ultrasonographic features of PTC in predicting cervical lymph nodes metastasis(CLNM).Methods A retrospective analysis was done on 169 PTC patients proved by surgery and pathology who underwent cervical lymph node dissection in the Department of Ultrasonography in Nanjing General Hospital of Nanjing Military Command from January 2016 to March 2017.The patients were divided into CLNM group(n=83) and non-CLNM group (n =86).Analysis was made on the related risk factors of PTC CLNM.Results Multivariate logistic regression analysis showed that age(OR=0.211,95％CI:0.078～0.571,P=0.002),nodule size (OR=3.116,95％CI:1.498～6.482,P=0.002) and shape (OR=3.000,95％CI:1.301～6.913,P=0.010) were risk factors for CLNM in PTC(P＜0.05).The sensitivity rates of patient's age,nodule shape,module size,and microcalcification for predicting CLNM in PTC patients were 91％、79％、61％、75％ respectively.Conclusion For PTC patients less than 30 years old,ultrasonographic features with maximal diameter of nodule ＞ 1 cm,irregular shape,and microcalcification have a certain predictive value on CLNM and can be used as the basis for the selection of intraoperative cervical lymph node dissection.
ABSTRACT
Objective To analyze the correlation between ultrasonographic features and pathological grade of clear cell renal carcinoma(CCRCC). Methods We retrospectively analyzed the conventional ultrasound and contrast enhanced ultrasound in 150 cases of CCRCC from November 2013 to February 2017 which were confirmed by pathology in Institute of Nephrology of Nanjing Gener-al Hospital .Pathological grade was classified into Ⅰ , Ⅱ, Ⅲ,Ⅳ, with 122 cases of low grade CCRCC (grade Ⅰ and grade Ⅱ) and 28 cases of high grade CCRCC ( grade Ⅲ and grade Ⅳ ) .Their correlations with the features of conventional ultrasound and contrast en-hanced ultrasound were analyzed . Results The maximum diameter of the tumor ( low grade:40.00 ±16.11, high grade:56.43 ± 23.30), the minimum diameter of the tumor(low grade:34.73±14.02,high grade:45.79±16.17), rate of pseudocapsule displaying [low grade:presence52(74%),absence70(26%);high grade:presence4(14%),absence24(86%)], and the enhanced uniformity [low grade:uniformity 19(16%),Cystic change 95(78%),necrosis 8(6%);high grade:uniformity 5(18%),Cystic change 1(4%), necrosis 22( 78%) ] were related to the pathological grade .Binary logistic regression analysis showed that the main factors related to the pathological grade were the rate of pseudocapsule displaying (OR:4.348,95%CI: 1.252-15.096)and the enhanced uniformity (OR:11.425,95%CI:4.326-29.229) Conclusion The characteristics of CCRCC conventional ultrasound and contrast-enhanced ultra-sound were related to the pathological grade , and the main factors were the rate of pseudocapsule displaying and enhanced uniformity .
