Reversible Bevacizumab Induced Vocal Fold Necrosis

Abstract

Background: As the use of anti-angiogenic treatments is gaining scope in the treatment of various malignancies, there are increasing reports of laryngeal side effects. We report two cases of laryngeal necrosis and dysphonia.

Methods: Two patients with gynecological malignancies presented with severe dysphonia 11-24 months after initiation of bevacizumab therapy. Videostroboscopic examination of the larynx revealed bilateral ulcerations and eschar of the superior surface with absent mucosal waves.

Results: Patients were treated with discontinuation of the bevacizumab, vocal rest, and proton pump inhibitors. Both had improvement in voice and resolution of the eschar and ulceration. Shallow sulci and mild breathiness persisted in one patient.

Conclusion: With increasing use of potent systemic anti-angiogenic compounds, clinicians should be vigilant of this important complication of therapy. Time to onset of symptoms and reversibility of symptoms vary by patient and require further study. There may be long-term voice sequelae.
