Tx
Supraglottis
Primary tumor cannot be assessed
Tis
Supraglottis
Carcinoma in situ
T1
Supraglottis
Tumor limited to one subsite of supraglottis with normal vocal cord mobility
T2
Supraglottis
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 pyriforrn sinus) without fixation of the larynx
T3
Supraglottis
Tumor limited to larynx with vocal cord fixation and/or invades any of the following: postcricoid area, preepiglottic space, paraglottic space, and/or inner cortex of thyroid cartilage
T4a
Supraglottis
Moderately advanced local disease
Tumor invades through the outer cortex. of the thyroid cartilage and/or invades tissues beyond the larynx (e.g ., trachea, soft tissues of neck including deep extrinsic muscle of the tongue, strap muscles, thyroid, or esophagus)
T4b
Supraglottis
Very advanced local disease
Tumor invades prevertebral space, encases carotid artery, or invades mediastinal structures
Tx
Glottis
Primary tumor cannot be assessed
Tis
Glottis
Carcinoma in situ
T1
Glottis
Tumor limited to the vocal cord(s) (may involve anterior or posterior commissure) with normal mobility
T1a
Glottis
Tumor limited to one vocal cord
T1b
Glottis
Tumor involves both vocal cords
T2
Glottis
Tumor extends to supraglottis and/or subglottis,
and/or with impaired vocal cord mobility
T3
Glottis
Tumor limited to the larynx with vocal cord
fixation and/or invasion of paraglottic space and/
or inner cortex of the thyroid cartilage
T4a
Glottis
Moderately advanced local disease
Tumor invades through the outer cortex of
the thyroid cartilage and/or invades tissues
beyond the larynx (e.g., trachea, cricoid cartilage,
soft tissues of neck including deep extrinsic
muscle of the tongue, strap muscles, thyroid, or
esophagus)
T4b
Glottis
Tumor invades prevertebral space , encases carotid
artery, or invades mediastinal structures
