HER2 Support Group Forums - View Single Post - DIfferent subtypes of her2+ breast cancer with different prognoses being identified

there are different cytokeratins they check for as I recall CK 5 is the one specific to to triple negatives, not sure if only those that are basal or the others too. Will have to review.

Cytokeratins are not routinely tested for except 18/19 if they are looking for epithelial cells from breast cancer in the bone marrow.

The definition of the different subtypes of bc is still in flux but at least they are looking for the subtypes of her2 to try to determine which treatment is best for which subtype.
