    Abstract:
    Background: The optimal treatment modality for sinonasal mucosal melanoma (SNMM) remains controversial.Objectives: To investigate the impact of adjuvant therapy on SNMM.Material and methods: Ninety-two patients were retrospectively analyzed and were grouped into surgery alone (SA), surgery plus radiotherapy (SR), surgery plus chemotherapy (SC) and surgery plus radiochemotherapy (SRC) groups. Survival outcomes among different treatment modalities were analyzed using the Kaplan-Meier method and log-rank test.Results: Twenty-nine patients (31.5%) developed local recurrence, 10 patients (10.9%) had nodal metastasis, and 41 patients (44.6%) had distant metastasis. The overall survival time (OS) for SA, SR and SRC were 16, 29 and 27 months, respectively, and the disease-free survival time (DFS) were 10, 16 and 16 months, respectively. Significant differences were found between SA and SR (OS: p = .003; DFS: p = .016) and SA and SRC (OS: p = .002; DFS: p = .008). Superior outcomes were also found in SRC group compared to that in SA group for both OS (15 vs. 27 months, p = .012) and DFS (10 vs. 20 months, p = .017) in endoscopic approach.Conclusions and significance: SNMM had poor prognosis with high rates of local recurrence and metastasis. Adjuvant therapy improved survival outcomes for SNMM.
