Even HP was not tolerable for me as maintenance treatment for HER2+ MBC. The patient community calls Perjeta “poo-jeta” for a reason! Indefinite T-DxD is not realistic- survivors will have to contend with long term SEs of ADCs (think ❤️& liver fx) #ASCO25 #bcsm

In patients who relapse after receiving adjuvant abemaciclib: Median duration of first-line treatment is only 3.0 months! The number of such patients will soon increase. Their prognosis after relapse is extremely poor. We must urgently develop more effective strategies!
