Elective neck dissection versus elective neck irradiation in cT3/4N0 maxillary sinus squamous cell carcinoma: a propensity score matching analysis

Abstract

BackgroundMaxillary sinus squamous cell carcinoma (MS-SCC) is an infrequent malignancy, and determining the optimal neck management for patients with cT3/4N0 MS-SCC remains a topic of ongoing debate. The purpose of this study was to compare the prognoses and quality of life outcomes of patients who underwent either elective neck dissection (END) or elective neck irradiation (ENI) for cT3/4N0 MS-SCC.MethodsIn this retrospective study, we enrolled patients with surgically treated cT3/4N0 MS-SCC, and the impact of different neck management strategies on regional control and disease-specific survival was compared using propensity score matching. The effect of surgical intervention on quality of life was evaluated using the Mann-Whitney U test.ResultsOf the 120 patients included, 36 underwent END. After propensity score matching, our analysis indicated that END did not lead to superior outcomes than ENI, as demonstrated by comparable rates of regional control (p = 0.990) and disease-specific survival (p = 0.999). However, in the 70 returned questionnaires, patients who underwent END reported higher scores in the domains of appearance, chewing, and speech than did patients who underwent ENI.ConclusionsOur findings suggest that while END and ENI contribute to similar prognoses, END yields superior functional outcomes.
