Introduction: Head-and-neck cancer (HNC) treatments are elusive, and the hunt for an appropriate radiation strategy continues. Hypofractionation has the potential to provide several advantages, including a shorter overall duration that reduces rapid repopulation, dosage escalation with a higher biologically effective dose, and patient convenience. Hypofractionation is also beneficial in minimizing the danger of catching an infectious agent by reducing the number of hospital visits during the height of the COVID-19 epidemic. Materials and Methods: Between January 2020 and August 2021, 120 patients with squamous cell carcinoma of the head-and-neck subsites were randomly allocated to either the hypofractionated arm A (n = 60) or the standard fractionation arm B (n = 60) with concomitant treatment. Results: Locoregional tumor response, acute and late toxicity, and compliance were the study's endpoints. The normal tissue toxicities of each patient undergoing radiation were monitored weekly. Clinical and radiographic evaluations of locoregional control were conducted. Conclusion: Hypofractionation effectively overcomes tumor repopulation in rapidly growing tumors such as HNC, and we conclude in our study that the hypofractionated chemoradiation schedule appears to be more efficacious, with relatively superior locoregional control when compared to conventional chemoradiation with comparable normal tissue toxicities and compliance.
