inib therapy, the median PFS was 7.9 months (95%CI 4.1-11.7 months). Among the 15 patients with brain metastasis, the median PFS was 6.0 months (95%CI 2.2-9.8 months). The main toxicities related to pyrotinib were diarrhea in 57 (79.2%) cases, and 48 (66.7%) cases with grade 1-2 as well as 9 (12.5%) cases with grade 3.
