ABSTRACT
Antiangiogenic drugs have emerged as effective treatment options for patients with recurrent malignant gliomas (MGs). Though this class of drugs is generally well tolerated, rare life-threatening complications, including thromboembolism, hemorrhage, and gastrointestinal (GI) perforation, are reported. We describe six cases of GI perforation among 244 glioma patients (2.5%) during treatment with antiangiogenic agents in combination with chemotherapy and corticosteroids. Two patients succumbed to this complication, and the others recovered. Because GI perforation is a life-threatening yet treatable complication, neurooncologists must have a low threshold to consider it in patients on antiangiogenic drug therapy who present with abdominal pain and other GI complaints.
