Breast Pathology


Incyte Diagnostics' pathologists interpret over 4,700 breast specimens annually and maintain competency in all aspects of breast pathology, including new approaches to the diagnosis of ductal carcinoma in situ (DCIS) of the breast.  Breast biopsy diagnosis is challenging for all pathologists, and has become even more so as imaging-guided biopsies have become smaller, advances in imaging technology detect earlier lesions of breast cancer, and as special testing is requested on smaller samples.  

In 2011, Incyte Diagnostics' Laboratory Medical Director received the College of American Pathologists (CAP) Breast Predictive Factors Testing Advanced Practical Pathology Program Certificate of Recognition.  Designed for pathologists with intermediate or higher skill level in breast predictive factors testing, this selective training program covers the accurate performance and interpretation of breast cancer predictive factors in accordance with the guidelines of the American Society of Clinical Oncology  and the College of American Pathologists (ASCO/CAP).

Breast cancer develops along a continuum. Pathologists must be able to recognize the changes that stretch from normal cells to what is termed “atypical ductal hyperplasia” to ductal carcinoma in-situ and to invasive carcinoma.  Incyte Diagnostics has long recognized the importance of the breast biopsy interpretation, especially for early lesions.  

An additional check-and-balance procedure was implemented at Incyte Diagnostics in 2010, requiring all negative breast needle core biopsies and lumpectomies be reviewed by a second pathologist.  Previously, only positive results were reviewed by another pathologist.  In the event a particularly difficult diagnostic case is encountered, or there is disagreement among reviewing pathologists, the biopsy is referred to an outside consultant for expert opinion, especially for difficult cases of DCIS.
