Nutritional changes in patients with locally advanced head and neck cancer during treatment

Head and neck squamous cell carcinoma (HNSCC) includes a wide range of malignant tumors that originate in the different structures of this region of the body. Its presentation causes aesthetic alterations and disturbance of functions as phonation, swallowing, hearing and breathing [1]. The surgical option compromises all these basic functions, therefore an alternative for the treatment of these tumors in advanced stages is a conservative treatment [2]. These are based on the association of radiotherapy (RT) with concomitant chemotherapy [3], or bioradiotherapy [4,5] and, in some cases previous induction chemotherapy (iCT) [6].
