compartment soft tissue includes prelaryngeal strap muscles and subcutaneous fat.
T1: Tumor limited to one subsite of hypopharynx and/or 2 cm or less in greatest dimension.
T2: Tumor invades more than one subsite of the hypopharynx or an adjacent site, or
measures more than 2 cm but not more than 4 cm in greatest diameter without fixation
of hemilarynx. T3: Tumor measuring more than 4 cm in greatest dimension or tumor with
fixation of hemilarynx or extension to esophagus. T4b: Tumor with very advanced local
disease. Tumor invades prevertebral fascia, encases carotid artery, or involves mediastinal
structures. N0: No regional lymph node metastasis. N1: Metastasis in a single ipsilateral
lymph node, 3 cm or less in greatest dimension. N2: Tumor with metastasis in a single
ipsilateral lymph node, more than 3 cm but not more than 6 cm in greatest dimension,
or in multiple ipsilateral lymph nodes, none more than 6 cm in greatest dimension,
or in bilateral or contralateral lymph nodes, none more than 6 cm in greatest dimension.
N3: Metastasis in a lymph node more than 6 cm in greatest dimension. M0: No distant
metastasis. M1: Distant metastasis. (AJCC 7th ed.);
