I believe if means ER-, PR-, and Her2+

Estrogen Receptor, Progesterone Receptor, and the orphan receptor Her2/Neu.

So it means that both of the hormone receptors (ER and PR) are not expressed by the tumor, but that other known markers, like Her2 are expressed.

Expressing (being positive) is a good thing because it gives the clinicians something to target.
