BACKGROUND: Squamous cell carcinoma of the nasal cavity (NCSCC) is a rare, challenging malignancy. Surgical resection of this tumor can cause significant facial deformity, and indications for adjuvant or organ preservation therapies are not well-described.
OBJECTIVE: To examine the impact of treatment regimen on survival outcomes in NCSCC and to compare surgical to non-surgical based therapies.
METHODS: The National Cancer Database was queried for NCSCC from 2004 to 2014. Patient demographics, tumor characteristics, and treatment regimen were compared for the entire cohort. Multivariable Cox proportional hazards regression was performed for statistical analysis of treatment regimen and surgical margins on overall survival (OS) for early and late-stage disease.
RESULTS: A total of 1883 NCSCC patients were identified. The OS for the cohort was 83 months, and median age at diagnosis was 65 years. NCSCC patients who underwent surgery followed by adjuvant radiation therapy (RT) had a better OS compared to definitive RT (HR: 0.58, P < .001). In early stage NCSCC (T1/T2, N0), there was no significant difference in OS between patients treated with surgery only or surgery with adjuvant RT compared to definitive RT. In advanced stage NCSCC, surgery with adjuvant RT had a better OS compared to definitive chemoradiation. Having positive margins was shown to predict a worse OS when compared to negative margins in surgical patients despite adjuvant RT or chemoradiation.
CONCLUSIONS: NCSCC appears to be best treated with surgery followed by adjuvant RT in advanced-stage disease whereas in early-stage disease, surgery does not improve OS compared to definitive RT.
