Pathologic T

This input is used for staging

Notes

**Note 1:** Impaired vocal cord mobility, also described as vocal cord paresis, may suggest invasion of intrinsic laryngeal muscle. Fixation of the vocal cord may be described as immobility of the arytenoids noted on endoscopy, vocal cord paralysis, or deviation of larynx to fixed side. **Note 2:** Assign T1 for localized tumor only if no information is available to identify further extension.

Pathologic T	Pathologic T Display	Description	Registrar Notes
pX	pTX	Primary tumor cannot be assessed	Pathologic classification criteria met, evaluation done: Physician unable to assess T Surgical resection of primary tumor, extension not stated Physician assigns pTX, no other information available to determine T
p0	pT0	No evidence of primary tumor
pIS	pTis	Carcinoma in situ	Intraepithelial, noninvasive Stated as Tis
p1	pT1	Tumor limited to vocal cord(s) (may involve anterior or posterior commissure) WITH normal mobility	Note: T1 has subcategories of T1a and T1b. Assign T1 only when there is no information available to assign one of the subcategories Invasive tumor with normal vocal cord mobility: Confined to glottis, NOS: Intrinsic larynx Laryngeal commissure(s): Anterior Posterior; Vocal cord(s), NOS: True vocal cord(s) True cord(s) Localized, NOS Stated as T1 [NOS]
p1A	pT1a	Tumor limited to one vocal cord	One vocal cord with normal vocal cord mobility Stated as T1a with no other information on extension
p1B	pT1b	Tumor involves both vocal cords	Both vocal cords with normal vocal cord mobility Stated as T1b with no other information on extension
p2	pT2	Tumor extends to supraglottis and/or subglottis, and/or WITH impaired vocal cord mobility	Tumor involves adjacent regions(s) of larynx: Subglottis Supraglottis: Aryepiglottic fold Arytenoid cartilage: Corniculate tubercle Cuneiform tubercle Ventricular bands (false vocal cord(s)) Impaired vocal cord mobility Stated as T2
p3	pT3	Tumor limited to larynx WITH vocal cord fixation and/or Invades: Paraglottic space Inner cortex of the thyroid cartilage	Tumor limited to larynx WITH vocal cord fixation Involvement of intrinsic muscle(s) of larynx: Aryepiglottic Arytenoid Cricoarytenoid Cricothyroid Thyroarytenoid Thyroepiglottic Vocalis Inner cortex of thyroid cartilage (minor thyroid cartilage erosion) Stated as T3
p4	pT4	Not defined by UICC*#	Note: T4 has subcategories of T4a and T4b. Assign T4 only when there is no information available to assign one of the subcategories Tumor invades bone, nerve or extrinsic deep muscles Stated as T4[NOS]
p4A	pT4a	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 tongue Genioglossus Hyoglossus Palatoglossus Styloglossus Strap muscles Thyroid Esophagus	Base of tongue Hypopharynx, NOS Pre-epiglottic tissues Postcricoid area Pyriform sinus Vallecula Extension to/through: Cricoid cartilage Outer cortex of thyroid cartilage Extension to/through tissues beyond larynx: Strap muscles: Omohyoid Sternohyoid Sternothyroid Thyrohyoid Oropharynx Skin Soft tissue of neck Thyroid gland Trachea Cervical esophagus Stated as T4a
p4B	pT4b	Tumor invades: Prevertebral space Encases carotid artery Mediastinal structures	Stated as T4b
88	88	Not applicable	Primary site/histology not TNM defined Death certificate only (DCO) case
<BLANK>	BLANK	See Registrar Notes	Pathologic classification criteria not met Pathologic classification criteria met, evaluation done: Results not documented in patient record No surgical resection of known primary tumor (not T0) Resection insufficient for site-specific pathologic assessment No surgical resection of primary tumor and there isn’t a positive biopsy of a structure in the highest T category and highest N category Evidence of metastatic disease (pM1), no other workup Only Pathologic Stage Group documented (no T, N, or M information available)

\* T4 [NOS] is not defined by UICC in the 7th edition. Approval has been provided by UICC to use "Tumor invades bone, nerve or extrinsic deep muscles" as T4 [NOS]. \# T4 [NOS] is not defined in AJCC 7th edition.
