Endoscopy in patients with diarrhea during treatment with vascular endothelial growth factor receptor tyrosine kinase inhibitors: Is the cause in the mucosa?
We observed frequent mucosal abnormalities in the upper GI tract in VEGFR TKI-treated mRCC patients with diarrhea. Although these abnormalities provide insufficient explanation for the occurrence of diarrhea, we suggest to perform routine upper GI endoscopy in VEGFR TKI-treated patients with GI complaints.
Microvasculopathy observed early or late after OHT was not related to angiographically confirmed CAV.
