Abstract

Objective: This study is designed to analyze the survival benefits of elective neck dissection (END) in the treatment of squamous cell carcinoma of the maxillary sinus (MS-SCC) with clinically negative neck lymph nodes (N0) and no metastasis (M0). Study Design: The aim of this study was to evaluate whether END improves survival in patients with MS-SCC. Methods: This study is a population-based, concurrent retrospective database analysis of patients diagnosed with N0M0 MS-SCC from 2004 to 2013. Data were acquired from the Surveillance, Epidemiology, and End Results database. Frequency functions, Kaplan-Meier and Cox regression models were queried to analyze demographics, treatment status, and survival outcomes. Results: There were a total of 927 MS-SCC cases in the database between 2004 and 2013. This analysis revealed that for the overall cohort, END significantly and independently reduces the 5-year hazard of death in MS-SCC (hazard ratio [HR] = 0.646, 95% confidence interval [CI] = 0.419–0.873, P = 0.047). For early tumor (T)1/T2 tumors and T4 tumors, END did not independently improve 5-year survival. However, for T3 disease, END significantly reduced the 5-year hazard of death in MS-SCC (HR = 0.471, 95% CI = 0.261–0.680, P = 0.001), regardless of other covariates, including adjuvant radiation. There has been an increase in the percentage of MS-SCC surgeries that have been accompanied by END since SEER started collecting this data, although this did not demonstrate significance (R2 = 0.622). Conclusion: END improves disease-specific survival in patients with MS-SCC size > 4 cm and advanced T-stage (American Joint Committee on Cancer AJCC TIII). Therefore, surgeons performing maxillectomies should consider conducting an END concurrent with maxillectomy for those with size > 4 cm advanced stage cancer. Level of Evidence: 4.
