Survival and disease progression following solitary locoregional recurrence after head and neck radiotherapy

Research output: Contribution to journalArticlepeer-review

Abstract

Purpose: The management of solitary locoregional recurrence (sLRR) of head and neck squamous cell carcinoma (HNSCC) previously treated with radiotherapy (RT) is challenging. We aimed to identify characteristics associated with improved outcome. Methods: We identified patients treated with non-sinus, mucosal HNSCC who initially received IMRT. We characterized overall survival (OS) and locoregional control (LRC). Multivariable analysis (MVA) on survival and patterns-of-failure were performed using Cox and Fine-Gray competing risks analysis. Results: We identified 90 patients with available follow-up. In total, 67 (74%) patients received curative-intent salvage, while 23 (26%) received palliative care. On MVA, significantly improved OS and LRC were associated with lower initial N-classification and use of salvage total laryngectomy (TL) or neck dissection (ND). Conclusion: A nontrivial number of patients with sLRR cannot undergo salvage. Among patients treated with curative intent, TL or ND were clearly associated with improved OS and LRC.
