Title:
Liquid biopsies to track trastuzumab resistance in metastatic HER2-positive gastric cancer
Excerpt:
...we performed longitudinal analyses of 97 serial plasma samples collected from 24 patients who were HER2+ to track the resistance during trastuzumab treatment...Patients with PIK3CA/R1/C3 or ERBB2/4 mutations in the baseline plasma had significantly worse progression-free survival....Additionally, mutations in NF1 contributed to trastuzumab resistance...
