NAACCR XML: Tumor.extranodalExtensionHeadAndNeckPathological




Description
Extranodal extension (ENE) is defined as "the extension of a nodal metastasis through the lymph node capsule into adjacent tissue" and is a prognostic factor for most head and neck tumors. This data item pertains to pathological staging extension.
Rationale
Extranodal Extension Head and Neck Pathological is a Registry Data Collection Variable in AJCC. It was previously collected as Head and Neck SSF# 9 (Common SSF).
Codes

    
        
            0.0
            Lymph nodes positive for cancer but ENE not identified or negative
        
        
            0.1-9.9
            ENE 0.1 to 9.9 mm
        
        
            X.1
            ENE 10 mm or greater
        
        
            X.2
            ENE microscopic, size unknown

                Stated as ENE (mi)
            
        
        
            X.3
            ENE major, size unknown

                Stated as ENE (ma)
            
        
        
            X.4
            ENE present, microscopic or major unknown, size unknown
        
        
            X.7
            Surgically resected regional lymph nodes negative for cancer (pN0)
        
        
            X.8
            Not applicable: Information not collected for this case

                (If this information is required by your standard setter, use of code X.8 may result in an edit error)
            
        
        
            X.9
            Not documented in medical record

                No surgical resection of regional lymph nodes

                ENE not assessed pathologically, or unknown if assessed

                Pathological assessment of lymph nodes not done, or unknown if done

            
        
        
            
            
        
    

Each Site-Specific Data Item (SSDI) applies only to selected primary sites, histologies, and years of diagnosis. Depending on applicability and standard-setter requirements, SSDIs may be left blank.
