N0 Nasopharyngeal Cancer pN0 TNM Finding C64474 NCI Thesaurus Nasopharyngeal cancer with no metastasis to regional lymph nodes. (from AJCC 6th and 7th Eds.)
N1 Nasopharyngeal Cancer pN1 TNM Finding v7 C88972 NCI Thesaurus Nasopharyngeal cancer with unilateral metastasis in cervical lymph node(s), 6 cm or less in greatest dimension, above the supraclavicular fossa, and/or unilateral or bilateral, retropharyngeal lymph nodes, 6 cm or less in greatest dimension. Midline nodes are considered ipsilateral nodes. (from AJCC 7th Ed.)
N2 Nasopharyngeal Cancer pN2 TNM Finding v7 C88973 NCI Thesaurus Nasopharyngeal cancer with bilateral metastasis in cervical lymph node(s), 6 cm or less in greatest dimension, above the supraclavicular fossa. Midline nodes are considered ipsilateral nodes. (from AJCC 7th Ed.)
N3 Nasopharyngeal Cancer pN3 TNM Finding v7 C88974 NCI Thesaurus Nasopharyngeal cancer with metastasis in a lymph node (s) more than 6 cm in greatest dimension and/or to supraclavicular fossa. Supraclavicular zone or fossa is relevant to the staging of nasopharyngeal carcinoma and is the triangular region originally described by Ho. It is defined by three points: (1) the superior margin of the sternal end of the clavicle, (2) the superior margin of the lateral end of the clavicle, (3) the point where the neck meets the shoulder. This would include caudal portions of levels IV and VB. All cases with lymph nodes (whole or part) in the fossa are considered N3b. (from AJCC 7th Ed.)
N3a Nasopharyngeal Cancer pN3a TNM Finding C64478 NCI Thesaurus Nasopharyngeal cancer with metastasis to one or more lymph nodes greater than 6 cm in greatest dimension. (from AJCC 6th and 7th Eds.)
N3b Nasopharyngeal Cancer pN3b TNM Finding v7 C88975 NCI Thesaurus Nasopharyngeal cancer with extension to the supraclavicular fossa. Supraclavicular zone or fossa is relevant to the staging of nasopharyngeal carcinoma and is the triangular region originally described by Ho. It is defined by three points: (1) the superior margin of the sternal end of the clavicle, (2) the superior margin of the lateral end of the clavicle, (3) the point where the neck meets the shoulder. This would include caudal portions of levels IV and VB. All cases with lymph nodes (whole or part) in the fossa are considered N3b. (from AJCC 7th Ed.)
NX Nasopharyngeal Cancer pNX TNM Finding C64473 NCI Thesaurus Nasopharyngeal cancer in which the regional lymph nodes cannot be assessed. (from AJCC 6th and 7th Eds.)
