- Abstract
Purpose: To determine oncologic outcomes for patients with T4b sinonasal squamous cell carcinoma (SNSCC) treated with either surgery plus radiotherapy or definitive radiotherapy. Materials and Methods: Between January 1999 and December 2016, 85 patients with T4b SNSCC were analyzed retrospectively, there were 54 who received surgery plus radiotherapy (S + RT group) ± chemotherapy and 31 with definitive radiotherapy (RT group) ± chemotherapy. A 1: 2 propensity score matching (PSM) was performed to balance clinical factors and match patients. Kaplan–Meier method and Cox proportional hazard model were used to determine risk factors on survival outcomes. Results: The median follow‐up time was 76.7 months. The cumulative rates of locoregional control (LRC), distant metastasis‐free survival (DMFS), cancer‐specific survival (CSS), and overall survival (OS) at 5 years for entire cohort were 44.6%, 33.1%, 38.8%, and 33.9% respectively. After PSM, a total of 50 patients in S + RT group and 25 patients in RT group were analyzed. The 5‐year LRC, DMFS, CSS, and OS between S + RT and RT group were 58.6% versus 27.5% (p = 0.035), 42.8% versus 20.0% (p = 0.006), 50.3% versus 22.0% (p = 0.005), 44.5% veruss 20.0% (p = 0.004). The 5‐year survival rates with orbital retention between groups were 32.7% and 15.0%, p = 0.080. Multivariate Cox analysis revealed non‐surgical therapy (HR = 3.678, 95%CI 1.951–6.933) and invasion of cranial nerves (other than maxillary division of trigeminal nerves) (HR = 2.596, 95%CI 1.217–5.535) were associated with decreased OS. Conclusion: The inclusion of surgery in the multimodal management of T4b SNSCC might confer a survival benefit. Further prospective studies comparing the oncologic outcomes of S + RT with RT are warranted. Level of Evidence: 3 Laryngoscope, 133:2222–2231, 2023 [ABSTRACT FROM AUTHOR]
