Proteinuria and hypertension with tyrosine kinase inhibitors.

Tyrosine kinases are important for the development of pathological angiogenesis, a critical factor for survival and proliferation of tumor cells. Inhibition of tyrosine kinases either through targeted binding of its ligands or inhibition of its receptor has led to significant hindrance in angiogenesis and has improved survival for several cancers. Several of these antibodies or small molecules have been approved for treatment of recurrent and resistant cancers over the last decade. Although generally well tolerated, tyrosine kinase inhibitors have been linked with development of hypertension and proteinuria. We review the literature for incidence and severity of hypertension and proteinuria among several tyrosine kinase inhibitors, their pathophysiologic mechanisms, and provide a guide for screening and management.
