Abstract
Objective: Conventional wisdom is that the overwhelming majority of glottic cancer patients have a smoking history. However, in recent years observations suggested that an increasing number of glottic cancer patients had never been smokers. Therefore, an investigation was done examining the incidence of having a smoking history in a recent cohort of glottic cancer patients. Method: Retrospective review of 100 patients with glottic cancer to determine those reporting never having smoked. Results: Thirty-one of 100 did not have a smoking history. Clinical observations of those cases revealed that the disease morphology tended to be exophytic, papillary, and very vascular, often resembling recurrent respiratory papillomatosis (RRP). Remarkably, 2 of 31 were initially treated elsewhere assuming they had RRP and underwent 5 cidofovir injections. Both presented with advanced cancer, and the disease growth markedly accelerated coincident with the injections. Conclusions: Observations herein provide new insights that glottic cancer may be an evolving disease in which smoking is less exclusive, not unlike HPV-induced pharynx cancer. Similar to RRP, the angiogenic papillary disease morphology is well suited for voice-preserving angiolytic KTP laser treatment. Given the resemblance of some glottic cancers to RRP, great care should be taken when using cidofovir for papillary glottic neoplasms.
