Background Cisplatin is a frontline anticancer drug routinely used as part of concurrent chemoradiation administered at 3-weekly (100 mg/m 2 ) dose. However, its role as fractionated weekly dose has achieved favorable outcome in patients with locally advanced squamous cell carcinoma of head and neck (LA-SCCHN) during induction chemotherapy (IC). We therefore sought to compare the toxicity outcomes of patients with LA-SCCHN treated with platinum-based IC at a single institution study using split-dose cisplatin chemotherapy. We compared the hematological and renal toxicity profile between the weekly cisplatin (30 mg/m 2 ) (group A) versus 3-weekly (100 mg/m2) (group B) dosage schedule in this setting. Results The median age of the patients in groups A and B were 49.1 years and 48.27 years respectively with male:female ratio of 4:1. Most of the patients were of oropharyngeal cancers. Group A patients showed greater neutropenia (40.2%) than group B (20.6%). There was statistically significant fall in Hb% level in group A (13.9%) than in group B (11.9%). Renal profile showed greater rise in serum urea and serum creatinine (52.7%) in group B than in group A (52.29%) with statistically significant difference. Conclusions Since toxicities induced by high-dose cisplatin are irreversible and reduce quality of life in patients, the weekly regimen may be preferred owing to less renal toxicity, lesser hospitalization and more feasible in situations with high patient load and limited resources.
