January 30, 2008 – Lesion margins on mammograms and sonograms, calcifications on mammograms, and clinical cancer stage at diagnosis were significantly associated with HER2 status, according to a study conducted to determine if estrogen receptor (ER)-negative human epidermal growth factor receptor type 2 (HER2)-positive and ER-negative HER2-negative breast cancers have distinguishing clinical and imaging features with use of retrospectively identified patients and tissue samples.

In contrast to ER-negative HER2-negative tumors, ER-negative HER2positive tumors were more likely to have spiculated margins (56 percent vs 15 percent), be associated with calcifications (65 percent vs 21 percent), and be detected at a higher cancer stage (74 percent vs 57 percent). Conclusion: Biologic diversity of cancers may manifest in imaging characteristics, and, conversely, studying the range of imaging features of cancers may help refine current molecular phenotypes.
