Abstract
Background:
examine presentation and outcomes of sinonasal squamous cell carcinoma (SCC).
Methods:
A retrospective study utilizing the National Cancer Database, 2004 to 2015. The study population included adult patients diagnosed with primary sinonasal SCC.
Results:
A total of 537 patients were included. The mean age of the study population was 62.6 +/- 12.7 years. The median follow-up time was 35.6 months (interquartile range: 8.6-55.9). The histological variants identified are: (i) 66.7% keratinizing SCC, (ii) 21.6% non-keratinizing SCC, (iii) 8.0% papillary SCC, and (iv) 3.7% spindle cell carcinoma. Stage at presentation was: (i) 33.3% T1-2, N0, (ii) 31.8% T3-4a, N0, (iii) 13.8% T1-4a, N+, (iv) 17.0% T4b,N0-3, (v) 4.1% M1. Human papilloma virus (HPV) status was available for 96 patients and tested positive in 24 (25.0%) patients. By histological variants, 5-year survival was lowest for spindle cell carcinoma (40.0%), and highest for papillary SCC (70.1%). HPV negative tumors had a 5-year survival of 26.4%, while HPV positive tumors had a 5-year survival of 57.1% (P = <.001). Of the 255 patients with T1-4a, N0-3, M0 who had surgery of the primary site, 31 (12.2%) patients underwent endoscopic approach. The risk of positive postsurgical margins was not significantly different comparing endoscopic to open approach (23.8% vs 24.1%, P >.99).
Conclusions:
Sinonasal SCC could present at advanced stages in two-thirds of the population and exhibit a variety of histological subtypes. Like other sites of head and neck, HPV positive tumors are associated with a favorable prognosis. Endoscopic approach is comparable to open approach in terms of post-surgical margins.
