Mohamed Gouda: HER2 loss in not infrequent after treatment with T-DXd

Mohamed Gouda, Clinical Fellow at the University of Texas MD Anderson Cancer Center, shared a post on X about a recent paper he and his colleagues authored published in Clinical Cancer Research:

“Now published in Clinical Cancer Research!

HER2 loss in not infrequent after treatment with T-DXd. Almost one third of treated patients had complete loss and an additional one third had decrease in HER2 IHC score!”

Paolo Tarantino, Advanced research fellow at Dana-Farber Cancer Institute, shared this post, adding:

“Super interesting data, confirming something we’re observing more & more in clinic. Leads to 2 main questions: – is the HER2 downregulation leading to resistance, or just an epiphenomenon of T-DXd treatment? – does HER2 expression rebound after some time without T-DXd exposure?”
