CS Lymph Nodes

Notes

**Note 1**: For head and neck schemas, this field includes all lymph nodes defined as Levels I-VII and Other by AJCC. The complete definitions are provided in the General Rules, Section 2. **Note 2**: For head and neck schemas, additional information about lymph nodes (size of involved nodes, extracapsular extension, levels involved, and location of involved nodes above or below the lower border of the cricoid cartilage) is coded in CS Site-Specific Factors 1, 3-9. **Note 3**: If laterality of lymph nodes is not specified, assume nodes are ipsilateral. Midline nodes are considered ipsilateral. **Note 4**: For head and neck cancers, if lymph nodes are described only as "supraclavicular", try to determine if they are in Level IV (deep to the sternocleidomastoid muscle, in the lower jugular chain) or Level V (in the posterior triangle, inferior to the transverse cervical artery) and code appropriately. If the specific level cannot be determined, consider them as Level V nodes. **Note 5**: The description of lymph nodes has been standardized across the head and neck schemas. All lymph node levels and groups listed here are considered regional nodes for AJCC staging. Summary Stage 1977 and Summary Stage 2000 divide these nodes into regional and distant groups. **Note 6**: Retropharyngeal nodes have been moved from code 120 in CS Version 1 to code 050. Sipinal accessory nodes have been moved from code 750 to code 110. Lower deep cervical and transverse cervical nodes have been moved from code 750 to code 120. Mandibular nodes are included with Facial nodes.
