Criteria for the Diagnosis of Extranodal Extension Detected on Radiological Imaging in Head and Neck Cancer: HNCIG International Consensus Recommendations

Pathological evidence of extranodal extension (pENE) is known to be a negative prognostic factor in head and neck cancer (HNC). The available evidence suggests that radiologically or imaging-detected extranodal extension (iENE) is also associated with worse clinical outcomes. Although the reliable detection of iENE before initiation of treatment may help guide treatment selection, the diagnostic criteria and terminology used to report iENE are not widely agreed upon. The Head and Neck Cancer International Group (HNCIG) conducted a Delphi survey with the aim of developing a framework for decision-making on the most important areas of iENE diagnostic criteria and terminology requiring consensus.
