Abstract
|
|
|
|
The targeted cancer therapies that have been introduced in recent years are directed against cancer-specific molecules and signaling pathways, and thus, they have limited nonspecific toxicities. However, major vascular events, including stroke, are common in patients receiving tyrosine kinase inhibitors (TKIs). Inhibition of vascular endothelial growth factor receptor by some TKIs probably explains such events. Moreover, venous and arterial thromboses, atherosclerosis, and bleeding have been reported. Ischemic lesions can also occur due to impaired angiogenesis or endothelial dysfunction. However, the exact mechanisms of arterial stroke in patients with cancer receiving TKIs are unknown. Here, we have report two cases of non-thrombotic ischemic cerebrovascular events related to TKIs and described the high-resolution magnetic resonance imaging findings.
