Cisplatine

The aim of SWOAR TRIAL is to test sparing of Dysphagia/ Aspiration risk structures (DARS) and contra lateral submandibular gland by IMRT. HNSCC of the oropharynx, larynx and the hypopharynx treated with radical concurrent chemoradiotherapy or radiotherapy will be included in the trial. Patients will be randomized to SWOAR IMRT or standard IMRT. Swallowing function will be evaluated the MD Anderson Dysphagia Inventory (MDADI) scoring. Difference in the mean composite score of MDADI, a patient-reported outcome, at 6 months post radiotherapy is the primary outcome of the trial. Secondary Objectives include longitudinal assessment of aspiration prevention as evaluated by FEES by the 8 point penetration-aspiration score. Swallowing function, will be assessed by using the MDADI at baseline, at completion of CRT/RT, 3, 6, 12, and 24 months. Assessment of acute and late toxicity assessed at baseline, weekly during radiotherapy and then at 3, 6, 12, and 24 months post treatment as per RTOG and LENT SOMA score, respectively. Treatment outcomes will be assessed in terms of loco-regional tumor recurrence and overall survival, assessed at follow-up visits 3, 6, 12, and 24 months post treatment and then annually until 5 years post treatment.
