Scheduled IV Fluids for Throat Cancer

Patients undergoing concurrent chemoradiotherapy (CCRT) for head and neck squamous cell carcinoma frequently experience treatment-related toxicities including mucositis, dysphagia, acute kidney injury, pain, constipation, dermatitis, xerostomia, and trismus. Many of these toxicities may be exacerbated by dehydration and are commonly managed with clinician-directed intravenous (IV) hydration. This study will evaluate whether scheduled IV hydration reduces the incidence and severity of treatment-related toxicities compared with clinician assessment-based hydration. Participants will be randomized 1:1 to scheduled IV hydration or clinician assessment-based IV hydration beginning in Week 3 of concurrent chemoradiotherapy and continuing through one week following completion of chemoradiotherapy.
