Overview
According to the TNM staging system, the stages of laryngeal cancer are based on the tumor size, lymph node involvement, and distant metastasis
Staging
The following TNM staging is used for laryngeal cancer: [1]
| Supraglottis | |
| T1 | Tumor limited to one subsite of supraglottis with normal vocal fold mobility |
| T2 | Tumor invades mucosa of more than one adjacent subsite of supraglottis or glottis or region outside the supraglottis (e.g. mucosa of base of tongue, vallecula, medial wall of piriform sinus) without fixation of the larynx |
| T3 | Tumor limited to larynx with vocal fold fixation and/or invades any of the following: post-cricoid area, pre-epiglottic tissues, paraglottic space, and/or with minor thyroid cartilage erosion (e.g. inner cortex) |
| T4a | Tumor invades through the thyroid cartilage and/or invades tissues beyond the larynx, e.g. trachea, soft tissues of neck, including deep/extrinsic muscle of tongue (e.g. genioglossus, hyoglossus, palatoglossus and styloglossus), strap muscles, thyroid and esophagus |
| T4b | Tumor invades pre-vertebral space, mediastinal structures or encases carotid artery |
| Glottis | |
| T1 | Tumor limited to vocal fold(s) (may involve anterior or posterior commissure) with normal mobility
T1a. Tumor limited to one vocal fold T1b. Tumor involves both vocal folds |
| T2 | T2a. Tumor extends to supraglottis and/or subglottis with normal vocal fold mobility
T2b. Tumor extends to supraglottis and/or subglottis with impaired vocal fold mobility |
| T3 | Tumor limited to larynx with vocal fold fixation and/or invades paraglottic space, and/or with minor thyroid cartilage erosion (e.g. inner cortex) |
| T4a | Tumor invades through the thyroid cartilage or invades tissues beyond the larynx, e.g. trachea, soft tissues of neck, including deep/extrinsic muscle of tongue (genioglossus, hyoglossus, palatoglossus and styloglossus), strap muscles, thyroid and esophagus |
| T4b | Tumor invades prevertebral space, mediastinal structures or encases carotid artery |
| Subglottis | |
| T1 | Tumor limited to subglottis |
| T2 | Tumor extends to vocal fold(s) with normal or impaired mobility |
| T3 | Tumor limited to larynx with vocal fold fixation |
| T4a | Tumor invades through cricoid or thyroid cartilage and/or invades tissues beyond the larynx, e.g., trachea, soft tissues of neck including deep/extrinsic muscle of tongue (genioglossus, hyoglossus, palatoglossus and styloglossus), strap muscles, thyroid and esophagus |
| T4b | Tumor invades prevertebral space, mediastinal structures or encases carotid artery |
