compartment soft tissue includes prelaryngeal strap muscles and subcutaneous fat.
T1: Tumor limited to one subsite of hypopharynx and/or 2 cm or smaller in greatest
dimension. T2: Tumor invading more than one subsite of hypopharynx or an adjacent
site, or measuring more than 2 cm but not more than 4 cm in greatest dimension without
fixation of hemilarynx. T3: Tumor larger than 4 cm in greatest dimension or with fixation
of hemilarynx or extension to esophagus. N0: No regional lymph node metastasis. N1:
Tumor with metastasis in a single ipsilateral lymph node, 3 cm or smaller in greatest
dimension and ENE(-). N2: Tumor with metastasis in a single ipsilateral lymph node,
3 cm or smaller in greatest dimension and ENE( ); or larger than 3 cm but not larger
than 6 cm in greatest dimension and ENE(-); or metastases in multiple ipsilateral
lymph nodes, none larger than 6 cm in greatest dimension and ENE(-); or metastases
in bilateral or contralateral lymph nodes, none larger than 6 cm in greatest dimension
