Abstract
Several forms of laryngeal dysfunction and pathology can be attributed to the effects of chronic gastric reflux through direct acid irritation, from a reflex alteration in voluntary muscle tone or referred sensation. It is widely accepted that contact ulcers and granulomata over the arytenoid are associated with gastric reflux, but there have not been well-documented cases of glottic carcinoma that are reflux-related. This article presents six cases of glottic carcinoma, all with T1 lesions of the anterior two-thirds of the vocal cord. All of these patients are lifetime nonsmokers, and all had no other ailments other than moderately severe chronic gastroesophageal reflux. Clinical details from the study of these patients gives strong indication that the reflux may have been a factor in the development of the disease. In addition, review of 21 lifetime nonsmokers with glottic carcinoma presenting over a 10-year period at the Cancer Control Agency of British Columbia revealed that 48% had probably experienced reflux, compared to 16% in a group that had stopped smoking 10 or more years earlier. While this small number of cases cannot be said to prove the etiologic relationship between reflux and glottic carcinoma, it is important for the otolaryngologic community to be aware of the possible clinical relationship.
