NAACCR XML: Tumor.extranodalExtensionClin



Description

Extranodal Extension (ENE) Clinical is defined as "the extension of a nodal metastasis through the lymph node capsule into adjacent tissue" during the diagnostic workup. This data item defines clinical ENE for sites other than Head and Neck.



Rationale

Extranodal Extension Clinical (non-Head and Neck) is a Registry Data Collection Variable for AJCC. This data item was previously collected for Penis, SSF# 17.





Codes

        0 Regional lymph nodes involved, ENE not present/not identified during diagnostic workup
        1 Regional lymph nodes involved, ENE present/identified during diagnostic workup, based on physical exam WITH or WITHOUT imaging
        2 Regional lymph nodes involved, ENE present/identified during diagnostic workup, based on microscopic confirmation
        4 Regional lymph nodes involved, ENE present/identified, unknown how identified
        7 No lymph node involvement during diagnostic workup (cN0)
        8 Not applicable: Information not collected for this case  
 (If this information is required by your standard setter, use of code 8 may result in an edit error)
        9 Not documented in medical record  
 Clinical ENE not assessed or unknown if assessed during diagnostic workup  
 Clinical 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.
