Ultrasound morphology of invasive lobular breast cancer is different compared with other types of breast cancer.

The aim of this study was to evaluate the ultrasound (US) morphology of invasive lobular breast carcinomas (ILC) in comparison to that of invasive tumors of other histologic differentiation (TOD). Images of 406 breast lesions were included in this retrospective study. A total of 10 US criteria (shape, orientation, echogenicity, echo pattern, calcifications, margin, margin contour, lesion boundary, surrounding tissue and posterior acoustic features) were defined and determined.

Ultrasound criteria for ductal invasive breast cancer are modified by age, tumor size, and axillary lymph node status.

Purpose: To evaluate the influence of distinct clinicopathological parameters on ultrasound criteria for ductal invasive breast cancer.

Patients And Methods: The hardcopy prints of 337 ductal invasive breast cancers were analyzed. Ten ultrasound criteria (shape, orientation, echogenicity, echo pattern, calcifications, margin, margin contour, lesion boundary, surrounding tissue, and posterior acoustic features) were defined and correlated to age, tumor size, axillary lymph node status, and histological grading in a multivariate analysis.
