Potential role of transoral laser surgery for larynx carcinoma

Abstract

BACKGROUND AND OBJECTIVE: The treatment of larynx carcinoma is not settled to date. This prospective study evaluates the potential role of transoral laser surgery (TLS) for larynx carcinoma in a large series of unselected patients from a single institution. MATERIALS AND METHODS: A total of 504 consecutive patients with previously untreated carcinoma of the larynx were seen from 1986-1994. Their treatment modalities and results were prospectively evaluated. RESULTS: TLS was used in 290 patients (58%), total laryngectomy in 130 (26%), conventional partial laryngectomies in 31 (6%), and radiotherapy in 34 (7%). Nineteen (4%) had no curative treatment. Uncorrected actuarial survival for all patients with glottic carcinoma stages I and II treated with laser surgery (n = 202) was 80.2%, cause specific survival 96.7%, and local control 85.8%. Uncorrected actuarial survival for all patients with supraglottic carcinoma stages I and II treated with laser surgery (n = 40) was 49.0%, cause specific survival 78.6%, and local control 87.3%. CONCLUSION: TLS was the most important single treatment modality in this large series of unselected patients. It is a safe and time- and cost-effective alternative to radiotherapy for early stage larynx carcinoma.
