An interventional study of Hypofractionated Radiotherapy and Normofractionated Radiotherapy in Head and Neck Squamous Cell Carcinoma, Squamous Cell Carcinoma of the Head and Neck and Head and Neck Neoplasms, sponsored by Assiut University. Not yet recruiting. Open to participants aged 65 Years and older. Per ClinicalTrials.gov, last updated 2026-09-29.
Sponsored by Assiut University · Not applicable, Interventional, and Treatment
Standard radiotherapy for head and neck squamous cell carcinoma typically requires daily treatments over 6 to 7 weeks. 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.
The 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.
Eligible participants aged 65 years and older will be randomly assigned in a 1:1 ratio to receive either:
Participants will be monitored weekly during radiation treatment and followed for up to 1 year post-treatment. The primary outcome is locoregional control, with secondary outcomes assessing overall survival, disease-free survival, acute and late toxicities graded by CTCAE version 6.0, and health-related quality of life.
Exclusion Criteria:
Eligible older adults receive hypofractionated external beam radiotherapy using image-guided intensity-modulated radiotherapy (IMRT/VMAT). For definitive radiotherapy, a total dose of 45 Gy in 15 fractions (3 Gy per fraction) will be administered once daily, 5 fractions per week, over approximately 3 weeks. For postoperative/adjuvant radiotherapy, a total dose of 40.5 Gy in 15 fractions (2.7 Gy per fraction) will be administered once daily, 5 fractions per week, over approximately 3 weeks.
Radiation: Hypofractionated Radiotherapy
Eligible older adults receive standard normofractionated external beam radiotherapy according to institutional clinical practice guidelines (conventional fractionation, typically 1.8-2.0 Gy per fraction once daily, 5 fractions per week over 6-7 weeks) for definitive or postoperative head and neck squamous cell carcinoma.
Radiation: Normofractionated Radiotherapy
External beam radiotherapy administered using image-guided intensity-modulated radiotherapy (IMRT/VMAT) techniques. In the definitive setting, patients receive a total dose of 45 Gy in 15 fractions (3 Gy per fraction), delivered once daily, 5 fractions per week over approximately 3 weeks. In the postoperative/adjuvant setting, patients receive a total dose of 40.5 Gy in 15 fractions (2.7 Gy per fraction), delivered once daily, 5 fractions per week over approximately 3 weeks.
Standard external beam radiotherapy administered according to institutional protocols using conventional fractionation schedules (1.8-2.0 Gy per fraction, once daily, 5 fractions per week over 6-7 weeks) for definitive or postoperative management of head and neck squamous cell carcinoma.
Locoregional Control (LRC) Rate
Locoregional control is defined as the proportion of participants without evidence of persistent, recurrent, or progressive tumor at the primary disease site or regional cervical lymph nodes, assessed via clinical examination and diagnostic imaging.
Time frame: 1 year after completion of radiotherapy
