For older adults, these prolonged treatment schedules can cause substantial physical fatigue, travel burden, and treatment interruptions. Hypofractionated radiotherapy delivers higher doses of radiation per session over a shorter total treatment time (approximately 3 weeks), potentially limiting tumor cell regrowth, easing logistical demands on patients, and improving completion rates.\n\nThe purpose of this randomized controlled trial is to evaluate the clinical effectiveness, safety, and toxicity of hypofractionated radiotherapy compared with standard normofractionated radiotherapy in older adults with non-metastatic head and neck squamous cell carcinoma.\n\nEligible participants aged 65 years and older will be randomly assigned in a 1:1 ratio to receive either:\n\n* Hypofractionated Radiotherapy (Intervention): External beam radiotherapy delivered via image-guided intensity-modulated techniques (IMRT\u002FVMAT) once daily over approximately 3 weeks (45 Gy in 15 fractions for definitive therapy, or 40.5 Gy in 15 fractions for postoperative\u002Fadjuvant therapy).\n* Standard Normofractionated Radiotherapy (Comparator): External beam radiotherapy delivered once daily using conventional fractionation schedules over approximately 6 to 7 weeks according to institutional clinical standards.\n\nParticipants will be monitored weekly during radiation treatment and followed for up to 1 year post-treatment.
