Abstract Introduction  In head and neck cancer (HNC) patients, fatigue is present throughout the course of treatment and during follow-up. Cancer-related fatigue (CRF) is a significant treatment-related side effect experienced by oral cancer patients during and after treatment. CRF, when coupled with other side effects of oral cavity cancer, patients who undergo definitive treatment have some of the most dramatic acute side effects, and reduced overall quality of life (QoL). Although there are upcoming intervention strategies to manage CRF, the effect of exercise intervention is explored in this study. The rationale for considering exercise to manage CRF is that it may alleviate the combined effect of toxic treatment and decreased levels of activity during the treatment that reduces the capacity for physical performance. Objective  This study was conducted to investigate the effectiveness of exercise intervention on CRF, and its influence on functional capacity and QoL among patients with oral cavity cancer during and after their primary cancer treatment. Materials and Methods  Oral cavity cancer patients ( n  = 223), planned for only chemoradiotherapy with curative intent were screened for CRF. Based on the inclusion criteria, 69 patients were grouped randomly into experimental ( n  = 35) and control ( n  = 34) groups. Patients in the experimental group were provided structured exercise intervention, while the control group was offered standard and routine care. Structured exercise in this present study comprised moderate-intensity walking and resistance exercises using TheraBand every day for three to five times a week. CRF was assessed using symbolic assessment of fatigue extent and the functional capacity was assessed by 6-minute walk test (6MWT), maximal oxygen uptake (VO 2max ), and hand dynamometer. QoL was assessed using the European Organization for Research and Treatment for Cancer-QoL (EORTC QLQ-C30) and the Head and Neck Cancer module (HN35), while distress was assessed by the National Comprehensive Cancer Network (NCCN) Distress Thermometer. Randomized patients were assessed at four points. Result  The size effects in fatigue extent ( η p 2  = 0.40) and fatigue impact ( η p 2  = 0.41) were found to be moderate, and a positive correlation between 6MWT, fatigue extent, and fatigue impact was observed. Conclusion  This study suggests that exercise intervention has a significant positive impact on CRF, most aspects of QoL, and the functional capacity of the patients.
