BACKGROUND: Treatment of early glottic malignancies is controversial, particularly if postoperative endoscopy shows minimal/no residual disease.
METHODS: In a prospective nonrandomized study, we performed endoscopic laser surgery with curative intent in 59 patients with early glottic carcinoma presenting for radiotherapy after diagnosis elsewhere by random biopsy or cordal stripping. We analyzed outcomes and residual cancer in the specimen.
RESULTS: Clinical staging elsewhere did not correspond to (usually underestimated) the pathologic stage in 60.7%. In 22%, no tumor was identified on pathologic examination. After 35.3 months (mean), 93.2% were alive with no evidence of disease. Local control was achieved in 98.3% of the patients, and 13.5% of the patients required radiotherapy. The larynx was conserved in 98.3%.
CONCLUSIONS: Biopsy/stripping are best abandoned for persistent glottic lesions. A single laser endoscopic procedure provides reliable staging and definitive treatment in most cases using fewer resources. Biopsied patients presenting for treatment should be offered laser surgery as an alternative to radiotherapy.
