Just bear in mind, Enhertu is not used for mTNBC which has the worst prognosis and the shortest PFS and OS.

It also excluded those with interstitial lung disease or central nervous system metastasis that had been treated with steroids. Most likely because the immunosuppression by steroids would enhance the cytotoxicity of Enhertu.
