Abstract
Objective: The current study aimed to investigate the value of definitive-intent (chemo)radiotherapy in treating sinonasal undifferentiated carcinoma (SNUC) in a single institution. Methods: The medical records of 21 patients with SNUC treated with definitive-intent (chemo)radiotherapy between 2011 and 2021 in one single institution were retrospectively reviewed. We analyzed the treatment efficiency and long-term survivals. Results: A total of 21 patients were included in this cohort, 12 patients presented with T4 stage at diagnosis, and 6 in T1/T2, 3 in T3 stage. Nine patients (42.9%, 9/21) showed cervical lymph node metastases. All the patients were scheduled to receive definitive (chemo)radiotherapy and five patients had been performed surgery for residual tumor after (chemo)radiotherapy. 66.7% (14/21) of patients had a complete response after the completion of treatment, 23.8% (5/21) of partial response, one of stable disease, and one of progressed disease. The 3-year overall survival of the entire group were 86.2%, and the 3-year progress-free survival were 66.3%, respectively. 52.4% of the patients (11/21) presented orbit invasion, compared with patients without orbit invasion, the patients who had orbit invasion were not found to have significantly poor 3-year overall survival (87.5% vs 83.3%, p = 0.38) and 3-year progression-free survival (75.0% vs 55.3%, p = 0.59). Conclusion: Definitive-intent (chemo)radiotherapy could be the preferred treatment for patients with advanced SNUC, and salvage surgery should be performed for the lesions showing stable disease, progressed disease, or residual tumor. Advances in knowledge: The value of definitive chemoradiotherapy in treating sinonasal undifferentiated carcinoma.
