Washington University’s Cytogenetics and Molecular Pathology Laboratory processes a variety of tissue specimens for the diagnosis and monitoring of many types of cancer.
We offer chromosome analysis, FISH and FFPE FISH to detect translocations, deletions, duplications, amplifications, and to monitor the status of bone marrow transplants. We correlate the histology with FISH testing utilizing customized as well as standardized probes to assess specific genetic loci that may assist in:
- Diagnosis of disease (e.g. IGH-CCND1, IGH-BCL2)
- Prognosis of disease (e.g. c-MYC, n-MYC, BCR-ABL, 1p/19q)
- Minimal residual disease (e.g. XY chimerism)
- Targetable drug therapy (e.g. EGFR. RET, ROS1, ALK, HER2)
