BACKGROUND:Sinonasal mucosal melanoma is a rare malignancy with poor prognosis. METHODS:Patients with sinonasal malignant melanoma who underwent surgery by different approaches were included in this study. Overall survival (OS) and event-free survival were calculated, and statistically significant variables by univariate analysis were entered in a multivariate Cox regression model. RESULTS:Pathological staging was pT3, pT4a, and pT4b in 30 cases (51.7%), 17 cases (29.3%), and 11 cases (19.0%). At 3 and 5 years, OS was 43.5% and 29% and event-free survival was 23.6% and 12.4%, respectively. At univariate analysis, OS was significantly influenced by male sex, advanced pT classification, positive margins, and surgical approach; event-free survival was affected by positive margins. At multivariate analysis, the risk of death was independently associated with male sex (hazard ratio [HR] = 2.27; p = .04) and positive margins (HR = 2.32; p = .03). CONCLUSION:Male sex and positive margins were negative prognostic factors. Endoscopic resection did not show an increased risk of death compared with more extensive surgical approaches.
