Induction Chemotherapy in Squamous Cell Carcinoma of Tongue—Still a Slippery Role?

Abstract

Abstract Background Tongue cancers are more common in the Indian subcontinent and a leading cause of morbidity and mortality among oral cavity cancers. Induction chemotherapy has been considered an intriguing and smart option for many reasons, but even after years of studies and debates, its role has not been fully established in the management of tongue cancers. Materials and Methods In this study, we evaluated 17 patients with oral tongue carcinomas with locally advanced stage, enrolled into a protocol of three drug (docetaxel, cisplatin, 5-fluorouracil) induction chemotherapy for three cycles. After completion of the three cycles, patients were clinically and radiologically re-evaluated and surgery was done if locally operable. Results At the completion of three cycles, five patients were partial responders, four patients were complete responders, and five patients had progressive disease after three cycles. Those patients with response underwent surgery. There were no significant morbid intraoperative or postoperative complications observed in seven out of nine patients. At the end of treatment completion, five out of nine patients had tumor residue/high-risk features and were planned for adjuvant radiotherapy. Conclusion For locally advanced oral tongue carcinomas, the role of induction chemotherapy before surgery has been fruitful and its impact on function preservation with acceptable oncological clearance is an emerging alternative. Spacing chemotherapy and radiotherapy reduce the incidence of adverse effects of combined treatment.
