All patients received radiation therapy. This radiation was exclusive in 43.7% of cases or adjuvant to partial surgical resection in 56.3%. The median dose of radiotherapy was 54 Gy (46 - 60) and it was delivered by a three-dimensional conformal radiotherapy technique in 15 patients and volumetric modulated arc therapy in one. There were few acute complications such as grade I and II mucositis and dermatitis. After a median follow-up of 5.6 years (2 - 13.4), local control, defined by radiological stability or regression, was obtained in 14 patients, two patients progressed and one died. Progression-free survival rates at 5 and 7 years were 93.8% and 78.1% respectively, and overall survival at 5 and 7 years was 92.3%. </span><b><span style="font-family:Verdana;">Conclu</span><span style="font-family:Verdana;">sions:</span></b><span style="font-family:Verdana;"> Surgery is the first-line treatment for HNPGls.
