Primary radiation therapy for early glottic cancer
1Department of Otolaryngology and Communicative Disorders, Cleveland Clinic Foundation, OH 44195, USA.
Objectives/Hypothesis:
Early glottic squamous cell carcinoma can be effectively treated with either radiation or surgical intervention. We evaluated our experience treating early glottic cancer with primary radiation therapy and our vertical hemilaryngectomy (VHL) salvage experience.
Study Design/Methods:
Retrospectively, patient records between January 1986 and December 1994 were reviewed and 45 patients with early glottic squamous cell carcinoma who received full-course radiation therapy at the Cleveland Clinic Foundation were identified.
Results:
Local control after radiation therapy was 80% overall, 87.5% for T1 lesions, and 75% for T2 lesions. Four patients underwent VHL for salvage after local recurrence; 1 was successfully salvaged with VHL. Five patients underwent total laryngectomy salvage after radiation therapy; all were successful. Only 1 of the 6 patients who were originally candidates for VHL before radiation therapy was successfully salvaged with the larynx preserved.
Conclusions:
Our local control rates using primary radiation therapy are consistent with prior published series, but voice sparing salvage is poor.
