While alcohol and tobacco use have long been the primary etiological factors, the role of human papillomavirus (HPV) in oropharyngeal cancer is increasing. Diagnoses and relapses should always be discussed by an expert multidisciplinary team. For localized stages, surgery or radiotherapy should be used as single-modality treatments, while locoregional stages require combined modality approaches. In the case of recurrent or metastatic disease, curative intent should be considered for patients with local recurrence or oligometastatic disease, while systemic treatment is recommended for all other cases. These guidelines, developed by the authors on behalf of the Spanish Society of Medical Oncology (SEOM) and the Spanish Group for the Treatment of Head and Neck Tumors (TTCC), review available evidence and provide expert recommendations based on the current literature.  \nKeywords Head and neck cancer · Guidelines · Chemoradiotherapy · Immunotherapy  \n* Virginia Arrazubi[varrazubi@gmail.com](varrazubi@gmail.com)  \nLara Iglesias  \n[laracarmen.iglesias@salud.madrid.org](laracarmen.iglesias@salud.madrid.org)  \nMarc Oliva  \n[marc.oliva.bernal@gmail.com](marc.oliva.bernal@gmail.com)  \nPedro Pérez Segura  \n[peregasconcto@gmail.com](peregasconcto@gmail.com)  \nJordi Rubió -Casadevall  \n[jrubio@iconcologia.net](jrubio@iconcologia.net)  \nGemma Bruixola  \n[gema.bruixola@gmail.com](gema.bruixola@gmail.com)  \nAlberto Carral  \n[alberto_carral@hotmail.com](alberto_carral@hotmail.com)  \nBeatriz Castelo  \n[castelobeatriz@gmail.com](castelobeatriz@gmail.com)  \nBeatriz Cirauqui  \n[bcirauqui@iconcologia.net](bcirauqui@iconcologia.net)  \nAntonio Rueda  \n[rueda.dominguez@gmail.com](rueda.dominguez@gmail.com)  \n1 Medical Oncology Department, Hospital Universitario de Navarra, Instituto de Investigación Sanitaria de Navarra (IdiSNA), Pamplona, Spain  \n2 Medical Oncology Department, Hospital Universitario 12 de Octubre, Madrid, Spain  \n3 Medical Oncology Department, Institutd’InvestigacióBiomèdica de Bellvitge (IDIBELL), Institut Català d’Oncologia (ICO) L’Hospitalet, Barcelona, Spain  \n4 Medical Oncology Department, Hospital Clínico San Carlos, IdISC (Instituto de Investigación del Hospital Clínico San Carlos), Madrid, Spain  \n5 Medical Oncology Department.
