Abstract
Background/Aim: Prognosis of patients with unresectable squamous cell carcinomas of the head and neck requires improvement. This retrospective study compared accelerated radiotherapy plus chemotherapy to conventional radiochemotherapy. Patients and Methods: Patients received definitive treatment with accelerated radiotherapy plus chemotherapy (group A, n=10) or conventional cisplatin-based radiochemotherapy (group B, n=85). Groups were matched for several patient and tumor characteristics and compared for locoregional control (LRC), overall survival (OS) and toxicities. Additionally, accelerated radiotherapy plus chemotherapy and chemotherapy regimens in group B were compared for LRC and OS. Results: Treatment type had no significant impact on LRC (p=0.98) and OS (p=0.57). In group A, toxicities occurred more often, including grade ≥3 mucositis (p=0.041), grade ≥2 lymphedema (p=0.007) and grade ≥3 leucopenia (p=0.007). Best 2-year LRC (p=0.39) and OS (p=0.015) was achieved with 20 mg/m2 cisplatin days 1-5 every 4 weeks; accelerated radiochemotherapy resulted in second-worst outcomes. Conclusion: Given the limitations of this study, accelerated radiotherapy plus chemotherapy provided no significant benefit but increased toxicity compared to conventional radiochemotherapy.Keywords
