Background: Head-and- neck squamous cell carcinoma (HNSCC) is a commonly occurring malignancy in the geriatric population. However, there is a scarcity of data regarding the efficacy and safety of concurrent chemoradiotherapy (CRT) in these patients. Objectives: We performed a post hoc analysis of a randomized study conducted at our institution to compare the outcomes and toxicities of concurrent CRT in older versus younger patients with HNSCC. Materials and Methods: The present analysis is based on a study conducted at Tata Memorial Hospital, Mumbai, India, on patients with locally advanced HNSCC, planned for radical concurrent CRT. The patients were randomized to receive cisplatin either once-a-week at a dose of 30 mg/m2 or once-in-3-weeks at a dose of 100 mg/m2. The database of this study was used for the post hoc analysis. We evaluated the differences in the demographic and clinical features, grade 3 or worse adverse events, compliance to treatment, locoregional control (LRC), progression-free survival (PFS), and overall survival (OS) between the older (aged ≥ 60 years) and the younger patients. Results: Out of 300 patients, 283 (94.3%) comprised the younger cohort (age
