The Incidence of Thyroid Cartilage Invasion In Early Stage Laryngeal Carcinoma: Our experience on sixty two patients

Abstract

Laryngeal cancer represents 4,5% of all malignancies and 28% of cancers of the upper aerodigestive tract. Pretreatment staging of laryngeal carcinoma should involve evaluation of thyroid cartilage invasion. Cartilage invasion which determines T stage in laryngeal cancer can be detected in 26-75% of the patients and if not detected preoperatively, may cause errors in staging in 40-50% of the patients.¹ In recent TNM classification inner cortex involvement is classified as T3 and outer cortex invasion is T4a.²
