Overview
Most laryngeal cancers are squamous cell carcinomas, reflecting their origin from the squamous cells which form the majority of the laryngeal epithelium. Cancer can develop in any part of the larynx, but the cure rate is affected by the location of the tumor. For the purposes of tumor staging, the larynx is divided into three anatomical regions: the glottis (true vocal cords, anterior and posterior commissures); the supraglottis (epiglottis, arytenoids and aryepiglottic folds, and false cords); the subglottis. Most laryngeal cancers originate in the glottis. Supraglottic cancers are less common, and subglottic tumors are least frequent.Laryngeal cancer may spread, either by direct extension to adjacent structures, by metastasis to regional cervical lymph nodes or more distantly, through the blood stream. Distant metastates to the lung are most common.
