Abstract
BACKGROUND: The current capacity of preoperative ultrasound examinations to estimate the intraductal spread of primary breast cancer was evaluated. The current ultrasound examination has three modes, B-mode, vascularity, and elastography, and this study evaluated this comprehensive ultrasound examination. METHODS: Of the patients undergoing breast cancer surgery for a breast mass at our department between April 2010 and March 2011, we evaluated 99 in whom breast-conserving surgery was scheduled, and performed preoperative ultrasounds and stored the digital ultrasound images and pathology data. ACR BI-RADS(®)-US lexicon elastography for the main mass and peri-tumoral ductal lesions (PTDL, defined in main sentence), and the vascularity and elasticity pattern (defined in main sentence) were evaluated. RESULTS: A cut end-negative resection at the first procedure after ultrasound estimation was achieved in 76.7%, and the breast was conserved by an additional resection with a negative margin in 90.6%. Shadowing of mass posterior acoustic features tends to indicate cut end-negative results significantly. There was a statistical difference between "vascularity in PTDL" and "elasticity pattern of PTDL". CONCLUSION: Using the recent comprehensive ultrasound examination with vascularity and elastography was useful for the preoperative estimation of intraductal spread of primary breast cancer in our retrospective study.
