Conclusion Adequate staging procedures can lead to the identification of the primary site in most cases. Our data confirms thats in cases of real HNCUP an intensified multimodal treatment and an extensive nodal/mucosal coverage with RT have shown no benefit on survival outcomes. ENE is closely linked to worse PFS and MFS and should prompt the investigation of new therapeutic approaches. Due to the lack of clinical prognostic factors we support molecular and radiomic research in better stratification of HNCUP.
