An evaluation of vertical partial laryngectomy for carcinoma of the larynx

Abstract

Radiation therapy for early laryngeal carcinoma has produced excellent results. In some cases, however, radiation resistant carcinoma and radiation failures, partial laryngectomy is suitable.Forty-two patients oft of 402 goottic carcinoma (8.2%) who underwent vertical partial laryngectomy between 1962 and 1981 in National Cancer Centrer Hospital were reviewed.Primary cases weve 33 patients, radiation failures were 6 and radiation injuries were 3.In primary cases, 16 patients were T1N0, 8 were T2N0 and 9 were T3N0 at the time of diagnosis. Subgroup of vertical partial laryngectomy, frontolateral was 27 patients, anteriorfrontal was 2, cordectomy was 2, vertical hemilaryngectomy was 2. Four patients suffered local recurrence between 6 and 36 months after initial treatment, but all were salvaged by total laryngectomy. Three patients produced cervircal metastasis within 6 months after initial treatment. Upper deep cervical lymph nodes metastasis were 2 patients and middle cervical 2. All of them were conrolled by radical neck dissection for over 5 years.Five years crude survival rate was 87.9% (29/33) in primary cases.Nine cases of fixed true vorcal cocd (T3) were treated by extended frontolateral partial laryngectomy and vertical hemilaryngectomy. If there is few functional troubles, these procedured were occasionally useful for T3 glottic cacinoma. In radiation failures, all of them were rT1N0 at the time of recurrence, and were salvage by partial laryngectomy and following treeatment without major complications. Vertical partial laryngectomy was considered one of the optimal treatment as a salvage surgery for early glottic carcinoma.Radiation injuries were healed by vertical partial laryngecttomy.
