Of note, amplifications in the 11q13 chromosome (including FGF3, FGF4, and FGF19), which was found to be negatively correlated with MSI-H in this study, was reported to be potentially associated with hyperprogression upon immune checkpoint inhibitors as observed in three out of four patients with lung cancer or esophageal adenocarcinoma 18. The gene discussed is FGF19; the disease is lung cancer.
