Outcome of Open Surgical Therapy for Glottic Carcinoma

Abstract

A retrospective review was undertaken of the medical records of 270 patients with carcinoma of the glottic larynx. Patients were staged pathologically, and clinical pathologic correlates were made with outcome. In 92 patients with early glottic cancer, the 2-year rate of no evidence of disease for T1 was 98%, and for T2, 84%. Vertical partial laryngectomy resulted in voice preservation in 89%. Patients treated for advanced (T3 or T4) glottic carcinoma underwent total laryngectomy with or without neck dissection. Cervical nodes were involved in 22% of T3 and 41% of T4 patients at the time of treatment. Survival with no evidence of disease was chiefly determined by the development of regional recurrence, distant metastasis, and new primary cancer. Distant metastasis was associated with extracapsular spread (p = .003). Patients treated for T4 glottic carcinoma with neck dissection had improved survival compared with patients treated with laryngectomy alone (p = .006). Improved survival must be aimed at regional control, prevention, and management of distant metastasis and new primary carcinoma.
