Current management of sinonasal undifferentiated carcinoma
Background:
The management of sinonasal undifferentiated carcinoma (SNUC) remains unclear. Low incidence and poor outcomes make treatment standardization difficult. The objective of this study was to review the used treatment and our outcomes.
Methods:
From 2001 to 2013, 17 cases of SNUC were treated at our department. Charts were reviewed for standard demographic, tumour size and extension, histological features, treatment strategies, surgical approach, adjuvant therapies, outcomes and complications.
Results:
All patients presented with extensive local disease and 2 patients also had neck metastases. All patients were treated using a multimodality approach: 10 patients underwent surgery and postoperative chemoradiation, 1 patient was treated with surgery and adjuvant radiotherapy, 3 patients were treated with neoadjuvant chemotherapy, surgery and postoperative chemoradiation and the remaining 3 patients were treated with chemoradiotherapy. After median follow-up of 39 months 6 patients developed recurrences. The 3-year local control rate was 76% and the 5-year rate of overall survival was 58%.
Conclusions:
Management and outcomes of SNUC have improved due to advances in surgery and radiotherapy. Gross tumour resection followed by postoperative radiotherapy should be the standard of care in patients with SNUC. High-precision high-dose radiotherapy should be implemented to try to improve the outcomes.
