CORRELATION OF THE POSTERIOR ECHO ATTENUATION ON ULTRASONOGRAPH, FIBROUS/CELLULAR RATIO AND HISTOPATHOLOGY GRADE WITH INFILTRATING DUCTAL CARCINOMA OF THE BREAST
摘要
Abstract
Objective:To probe the relationship between the posterior echo attenuation on ultrasonographic signs, fibrous/cellular (F/C) ratio and histological grade in cases of infiltrating ductal carcinoma (IDC)of breast, evaluated the clinical value in predicting the histological grade by means of ultrasonograph. Methods:A total of 110 patients with pathologically confirmed with infiltrating ductal carcinoma (IDC) of breast were retrospected between January 2008 and September 2009. The size of breast tumor, ultrasonographic appearance of the type, micro-calcification, acoustic enhancement, posterior echo attenuation and ultrasound diagnosis were recorded. The correlation between the posterior echo attenuation of infiltrating ductal carcinoma (IDC), the F/C ratio and histological grades was analyzed. Results:The lesion diameter was 0.7 ～4.0 cm in 110 IDC,with a median diameter of(2.36±0.82)cm. The ultrasonography showed acoustic enhancement in 7 cases, posterior echo attenuation in 103 cases, 103 cases of posterior echo attenuation showed: Ⅰ in 48 cases; Ⅱ in 36 cases; Ⅲ in 19 cases lesions. F/C ratio:(+) in 61 cases;(++) in 38 cases;(+++) in 11 cases. Histological grades of the IDC: Ⅰ grade in 29 cases; Ⅱ grade in 66 cases; Ⅲgrade in 15 cases. The posterior echo attenuation and the F/C ratio was positively correlated ( rs =0. 149,P =0. 134) in IDC, and negative correlation with histological grades ( rs =-0. 179, P =0. 077). Both of them were not statistically significant. Conclusion:IDC posterior echo attenuation ultrasound characteristics are associated with the pathological tissue in lesions. The posterior echo attenuation can prompt the histological grades in IDC.关键词
