Abstract: HER2 heterogeneity and RTK alterations are more frequent among patients with shorter PFS. HER2 testing and tissue/plasma ctDNA NGS upon progression demonstrate that 8 of 16 (50%) of patients had HER2 negative tumors post-treatment, and 2 ERBB2 amplified tumors pre-treatment were non-amplified post-treatment. Additionally, frequent alterations in PI3K, cell cycle proteins, Ras-Raf, EGFR, FGFR1/2, and MET were found upon progression, and potentially associated with treatment resistance.
