The roof of the nasal cavity is formed by the nasal bone. The floor of the nasal cavity, which forms the roof of the mouth, is composed of the bones of the hard palate: the horizontal plate of the palatine bone posteriorly and the palatine process of the maxilla anteriorly. Note 2: "Bony invasion" does not include extension to palate, cribriform plate, or pterygoid plates. Extension to these structures is coded separately. Note 3: Base of skull NOS only if no information is available to code to more specific bony structures in the skull. Note 4: In code 700, "minimal extension to anterior cranial fossa" implies tumor pushing through the cribriform plate, but without invasion of the dura or brain. Note 5: Use code 300 for localized tumor ONLY if no information Is available to assign codes 100, 110, 200, or 410. Note 6: Use code 110, 410, 680, 725, 810, or 815 if the physician's assignment of T category is the ONLY information available about the extent of the tumor.

Nasal Cavity CS Lymph Nodes (Revised: 09/02/2009) 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 Instructions. 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 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.

Nasal Cavity CS Lymph Nodes Eval (Revised: 10/26/2009) Note 1: This field is used primarily to derive the staging basis for the N category in the TNM system. It records how the code for the item "CS Lymph Nodes" was determined based on the diagnostic methods employed and their intent. Note 2: In the 7th edition of the AJCC manual, the clinical and pathologic classification rules for the N category were changed to reflect current medical practice. The N is designated as clinical or pathologic based on the intent (workup versus treatment) matching with the assessment of the T classification. When the intent is workup, the staging basis is clinical, and when the intent is treatment, the staging basis is pathologic. A. Microscopic assessment including biopsy of regional nodes or sentinel nodes if being performed as part of the workup to choose the treatment plan, is therefore part of the clinical staging. When it is part of the workup, the T category is clinical, and there has not been a resection of the primary site adequate for pathologic T classification (which would be part of the treatment). B. Microscopic assessment of regional nodes if being performed as part of the treatment is therefore part of the pathologic staging. When it is part of the treatment, the T category is pathologic, and there has been a resection of the primary site adequate for pathologic T classification (all part of the treatment). Note 3: Microscopic assessment of the highest N category is always pathologic (code 3). Note 4: If lymph node dissection is not performed after neoadjuvant therapy, use code 0 or 1. Note 5: Only codes 5 and 6 are used if the node assessment is performed after neoadjuvant therapy. Staging Basis 0 Does not meet criteria for AJCC pathologic staging: c No regional lymph nodes removed for examination. Evidence based on physical examination, imaging examination, or other non-invasive clinical evidence. No autopsy evidence used. 1 Does not meet criteria for AJCC pathologic staging based on at least one of the following criteria: c No regional lymph nodes removed for examination. Evidence based on endoscopic examination, or other invasive techniques including surgical observation, without biopsy. No autopsy evidence used. OR Fine needle aspiration, incisional core needle biopsy, or excisional biopsy of regional lymph nodes or sentinel nodes as part of the diagnostic workup, WITHOUT removal of the primary site adequate for pathologic T classification (treatment). 2 Meets criteria for AJCC pathologic staging: p No regional lymph nodes removed for examination, but evidence derived from autopsy (tumor was suspected or diagnosed prior to autopsy). 3 Meets criteria for AJCC pathologic staging based on at least one of the following criteria: p Any microscopic assessment of regional nodes (including FNA, incisional core needle bx, excisional bx, sentinel node bx or node resection), WITH removal of the primary site adequate for pathologic T classification (treatment) or biopsy assessment of the highest T category.

Note 2: the status of extracapsular extension whether assessed clinically or pathologically of any involved regional lymph node(s) coded in the CS Lymph Nodes field. Do not code extracapsular extension in any nodes coded in CS Mets at DX in this field. Note 3: A statement of the presence or absence of extracasular extension in a pathology report takes priority over clinical assessment. However, if the pathology report contains no statement about extracapsular extension, either positive or negative, the clinical assessment should be coded. If nodes are involved but there is neither a clinical assessment of extranodal extension nor a statement about it in the pathology report, use code 999. Note 4: According to AJCC (page 24), "Imaging studies showing amorphous speculated margins of involved nodes or involvement of internodal fat resulting in loss of normal oval-to-round nodal shape strongly suggest extracapsular (extranodal) tumor spread; however, pathologic examination is necessary for documentation of the extent of such disease."

Nasal Cavity CS Site-Specific Factor 8 Extracapsular Extension Clinically, Lymph Nodes for Head and Neck (Revised: 10/16/2009) Note 1: the status of extracapsular extension accessed clinically for any involved regional lymph node(s) coded in the CS Lymph Nodes field. Do not code extracapsular extensio in any nodes coded in CS Mets at DX in this field. Note 2: If nodes are involved clinically, and documentation of physical examination or imaging is available without a statement of extracapsular extension, use code 010. Note 3: If the only documentation is a reference to clinically involved nodes with no reference to extracapsular extension, use code 030. Note 4: If there is no information about clinical assessment of nodes, use code 999. Note 5: Clinical assessment can be by physical examination or imaging. According to AJCC, "ECS can be diagnosed clinically by a matted mass of nodes adherent to overlying skin, adjacent soft tissue, or clinical evidence of cranial nerve tissue. Radiologic signs of ECS include amorphous, spiculated margins of a metastatic node and stranding of the perinodal soft tissue in previously untreated patients." 000 No lymph nodes involved clinically 010 Nodes involved clinically, no extracapsular extension clinically 020 Nodes involved clinically, extracapsular extension clinically (nodes described as fixed or matted) 030 Nodes involved clinically, unknown if extracapsular extension 988 Not applicable: Information not collected for this case 997 Clinical examination of lymph nodes performed, unknown results 998 No clinical examination of lymph nodes 999 Unknown if regional lymph node(s) involved clinically, not stated Regional lymph nodes cannot be accessed Nasal Cavity CS Site-Specific Factor 9 Extracapsular Extension Pathologically, Lymph Nodes for Head and Neck (Revised: 08/25/2009) Note 1: the status of extracapsular extension assessed pathologically of any involved regional lymph node(s) coded in the CS Lymph Nodes field. Do not code extracapsular extension in any nodes coded in CS Mets at DX in this field. Note 2: If nodes are involved pathologically but there is no statement of extranodal extension in the pathology report, use code 010. Note 3: "microscopic" or "macroscropic" extranodal extension as stated in the final diagnosis. If not stated in the final diagnosis, code "microscopic" if extranodal extension is described only in the microscopic section of the pathology report and "macroscopic" if extranodal extension is described in the gross section of the pathology report. Note 4: "Macroscopic" extension takes priority over "microscopic" extension. Note 5: Use code 040 if pathologic extracapsular extension is described with no further information and the pathology report is not available for review. Note 6: Use code 050 if nodes involved pathologically with no further information about extracapsular extension. 000 No lymph nodes involved pathologically 29 April 2010 Part II - Upper Respiratory - 18 Version 02.02.00

Note 2: Record the results of any HPV testing performed on pathologic specimens from the primary tumor or a metastatic site, including regional nodes. HPV testing may be performed for prognostic purposes; testing may also be performed on metastatic sites to aid in the determination of the primary site. Note 3: The highest risk HPV types are types 16 and 18. Other high risk types are 31, 33, 35, 36, 45, 51, 52, 56, 58, 59, 68, 26, 53, 66, 67, 69, 70, 73, 82, 85 Low risk types are 6, 11, 32, 34, 40, 42, 44, 54, 61, 62, 64, 71, 72, 74, 81, 83, 84, 87, 89. The HPV vaccine is designed to protect against types 16 and 18 (associated with cervical cancer) and types 6 and 11 (associated with genital warts). Note 4: High risk may be abbreviated "hrhpv" or "HR-HPV". Note 5: Some tests for HPV, such as a hybrid capture test, only report negative or positive for high risk HPV without identifying types; use codes 025 and 050, respectively to report those test results. 000 HPV test negative; not positive for any HPV types Negative, NOS 010 LOW RISK positive (all positive type(s) are low risk) 020 HIGH RISK positive, specified type(s) other than types 16 or 18, WITH or WITHOUT positive results for low risk type(s) 030 HIGH RISK positive for HPV 16 WITHOUT positive results for HPV 18 or positivity of HPV 18 unknown, WITH or WITHOUT positive results for other high-risk types, WITH or WITHOUT positive results for low risk type(s) 040 HIGH RISK positive for HPV 18 WITHOUT positive results for HPV 16 or positivity of HPV 16 unknown, WITH or WITHOUT positive results for other high-risk types, WITH or WITHOUT positive results for low risk type(s) 29 April 2010 Part II - Upper Respiratory - 19 Version 02.02.00
