CSExtension codes of 000 and 999 are mapped to NA and AJCC stage group is derived as NA. Note 2: AJCC does not include a T1 or T2 category for mucosal melanoma of head and neck sites. Note 3: Use codes 310 and 315 for extension involving the mucosa only of adjacent sites. Use higher codes for extension involving deeper tissues of the primary or adjacent sites. Note 4: Use code 300 for localized tumor only if no information is available to assign code 105, 205, 250, 440, or 510. Note 5: Use code 440, 725, 810, or 815 if the physician's assignment of T category is the only information available about the extent of the tumor.

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: 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 4: 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 5: Retropharyngeal nodes have been moved from code 120 in CS Version 1 to code 050. Spinal 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.
