Assessment of breast cancer size: sonographic and pathologic correlation.

Purpose: Accurate presurgical assessment of tumor size in breast cancer is important for choosing appropriate treatment. We retrospectively compared presurgical sonographic measurements of tumor size with postsurgical measurements of size and other variables.

Methods: In 174 cases, tumor size was measured by sonography before surgery, and those measurements were compared with values obtained by histopathologic examination of the specimens.

Metastatic breast carcinoma in axillary lymph nodes: in vitro US detection.

Purpose: To establish the ultrasonographic (US) characteristics of benign versus metastatic lymph nodes.

Materials And Methods: One hundred fifty-eight axillary lymph nodes in 40 patients (age range, 31-73 years) surgically treated for breast cancer have been studied in vitro with a 7.5-MHz US probe in a water bath.
