Base of Tongue, Lingual Tonsil CS Lymph Nodes (Revised: 08/25/2009) Note 1: For head and nek shemas, this field inludes all lymph nodes defined as Levels I-VII and Other by AJCC. The omplete definitions are provided in the General Instrutions. Note 2: For head and nek shemas, additional information about lymph nodes (size of involved nodes, extraapsular extension, levels involved, and loation of involved nodes above or below the lower border of the rioid artilage) is oded in Site-Speifi Fators 1, 3-9. Note 3: If laterality of lymph nodes is not speified, assume nodes are ipsilateral. Midline nodes are onsidered ipsilateral. Note 4: For head and nek aners, if lymph nodes are desribed only as "supralaviular", try to determine if they are in Level IV (deep to the sternoleidomastoid musle, in the lower jugular hain) or Level V (in the posterior triangle, inferior to the transverse ervial artery) and ode appropriately. If the speifi level annot be determined, onsider them as Level V nodes. Note 5: The desription of lymph nodes has been standardized aross the head and nek shemas. All lymph node levels and groups listed here are onsidered regional nodes for AJCC staging. Summary Stage 1977 and Summary Stage 2000 divide these nodes into regional and distant groups.

Base of Tongue, Lingual Tonsil CS Lymph Nodes Eval (Revised: 10/26/2009) Note 1: This field is used primarily to derive the staging basis for the N ategory in the TNM system. It reords how the ode for the item "CS Lymph Nodes" was determined based on the diagnosti methods employed and their intent. Note 2: In the 7th edition of the AJCC manual, the linial and pathologi lassifiation rules for the N ategory were hanged to reflet urrent medial pratie. The N is designated as linial or pathologi based on the intent (workup versus treatment) mathing with the assessment of the T lassifiation. When the intent is workup, the staging basis is linial, and when the intent is treatment, the staging basis is pathologi. A. Mirosopi assessment inluding biopsy of regional nodes or sentinel nodes if being performed as part of the workup to hoose the treatment plan, is therefore part of the linial staging. When it is part of the workup, the T ategory is linial, and there has not been a resetion of the primary site adequate for pathologi T lassifiation (whih would be part of the treatment). B. Mirosopi assessment of regional nodes if being performed as part of the treatment is therefore part of the pathologi staging. When it is part of the treatment, the T ategory is pathologi, and there has been a resetion of the primary site adequate for pathologi T lassifiation (all part of the treatment). Note 3: Mirosopi assessment of the highest N ategory is always pathologi (ode 3). Note 4: If lymph node dissetion is not performed after neoadjuvant therapy, use ode 0 or 1. Note 5: Only odes 5 and 6 are used if the node assessment is performed after neoadjuvant therapy. Staging Basis 0 Does not meet riteria for AJCC pathologi staging: No regional lymph nodes removed for examination.
