Description

Bevacizumab (Avastin) is an antibody that targets vascular endothelial growth factor (VEGF). It may be effective against a number of solid tumors, but it is also associated with a number of serious toxicities, one of which is a hemolytic anemia.


 

Risk factors:

(1) combination therapy with paclitaxel/carboplatin

(2) combination therapy with sunitinib malate

 

Clinical features:

(1) hemolytic anemia with schistocytes

(2) thrombocytopenia

(3) variable renal dysfunction, hypertension and proteinuria secondary to glomerular thrombotic microangiopathy (podocytes produce VEGF)

(4) variable reversible posterior leukoencephalopathy syndrome

 

Diagnosis requires:

(1) exclusion of other causes

(2) reversal after discontinuation of therapy
