Ch 11 - Oropharynx (p16-) and Hypopharynx Flashcards
Tx
Oropharynx p16-
Primary tumor cannot be assessed
Tis
Oropharynx p16-
Carcinoma in situ
T1
Oropharynx p16-
Tumor 2 cm or smaller in greatest dimension
T2
Oropharynx p16-
Tumor larger than 2cm but not larger than 4cm in greatest dimension
T3
Tumor larger than 4cm in greatest dimension or extension to lingual surface of epiglottis
T4a
Moderately advanced local disease. Tumor invades the larynx, extrinsic muscle of tongue, medial pterygoid, hard palate, or mandible*
*Mucosal extension to lingual surface of epiglottis from primary tumors of the base of the tongue and vallecula does not constitute invasion of the larynx
T4b
Very advanced local disease. Tumor invades lateral pterygoid muscle, pterygoid plates, lateral nasopharynx, or skull base or encases carotid artery
Tx
Hypopharynx
Primary tumor cannot be assessed
Tis
Hypopharynx
Carcinoma in situ
T1
Hypopharynx
Tumor limited to one subsite of hypopharynx and/or 2cm or smaller in greatest dimension
T2
Hypopharynx
Tumor invades more than one subsite of hypopharynx or an adjacent site, or measures than 2cm but not larger than 4cm in greatest dimension without fixation of hemilarynx
T3
Hypopharynx
Tumor larger than 4cm in greatest dimension or with fixation of hemilarynx or extension to esophagus
T4a
Hypopharynx
Moderately advanced local disease. Tumor invades thyroid/cricoid cartilage, hyoid bone, thyroid gland, or central compartment of soft tissue*
*Central compartment soft tissue includes prelaryngeal strap muscles and subcutaneous fat
T4b
Hypopharynx
Very advanced local disease. Tumor invades prevertebral fascia, encases carotid artery, or involves mediastinal structures.
cNx

cN1
Metastasis in a single ipsilateral lymph node, 3cm or smaller in greatest dimension and ENE(-)
cN2a
Metastasis in a single ipsilateral node larger than 3cm but not larger than 6cm in greatest dimension and ENE(-)
cN2b
Metastasis in multiple ipsilateral nodes, none larger than 6cm in greatest dimension and ENE(-)
cN2c
Metastasis in bilateral or contralateral lymph nodes, none larger than 6cm in greatest dimension and ENE(-)

pN0
No regional lymph node metastasis
pN1
Metastasis in a single ipsilateral lymph node, 3cm or smaller in greatest dimension and ENE(-)
pN2a

pN2b
Metastasis in multiple ipsilateral nodes, none larger than 6cm in greatest dimension and ENE(-)
pN2c
Metastasis in bilateral or contralateral lymph nodes, none larger than 6cm in greatest dimension and ENE(-)
pN3a
Metastasis in a lymph node larger than 6cm in greatest dimension and ENE(-)
pN3b
Metastasis in a single ipsilateral node larger than 3cm in greatest dimension and ENE(+); or multiple ipsilateral, contralateral or bilateralnodes, any with ENE(+)
