Title: Pitfalls of Contrast Enhanced Ultrasound (CEUS) in determination of breast tumor biological dignity | ||
Author: V. LEHOTSKA, K. RAUOVA, L. VANOVCANOVA | ||
Abstract: The aim of this prospective study was to identify characteristics of breast lesions on contrast enhanced ultrasound (CEUS) that can be a source of diagnostic ambiguity and cause under- or overestimation of examined breast lesions. 215 women (range 23-76 y., mean age 53.16 y) with 215 breast lesions were examined by B-mode ultrasound, followed by CEUS and core biopsy. CEUS parameters: degree of opacification, character of washout and preliminary CEUS result (suspicious, non-suspicious, uncertain) were subsequently correlated with histopathological outcomes. Observed qualitative variables, CEUS results and their analysis with respect to histological type were evaluated using Pearson χ2 square test, p<0.05 was statistically significant. Differences in mean lesion size, mean age of patients, mean size between groups (malignant/ 215 tumors, 116 (53.93%) benign and 99 (46.05%) malignant lesions. 17 (14.66%) benign and 15 (15.15%) malignant lesions expressed atypical washout, 5 (4.31%) benign lesions had early washout and 38 (38.38%) had continuous washout (p<0.0001). 56 (48.28%) benign and 55 (55.56%) malignant lesions had middle degree of opacification, 19 (16.38%) benign had high and 5 (5.05%) malignant lesions low degree of opacification (p<0.0001). Finally, 38 (32.72%) benign and 20 (20.20%) malignant were marked CEUS uncertain. As risk lesions are considered fibroadenomas, fibrocystic lesions, papillomas and low grade DCIS or invasive breast tumors, especially lesions smaller than 10 mm. |
