Abstract

Abstract: Objectives: To analyse the failure patterns and prognostic factors influencing survival in patients with primary mucosal melanoma of the nasal cavity and paranasal sinuses. Materials and methods: Fifty-one patients were analysed retrospectively. Forty-eight, 33, 10, and 13 patients underwent surgery, radiotherapy, chemotherapy, and immunotherapy, respectively. Failure events, including local recurrence, regional relapse, distant metastases, and death, were examined. Results: During follow-up (median: 59.0 months), 36 patients experienced failure after treatment, including local ( n = 17), regional ( n = 8), and distant organ ( n = 23) metastases. The median failure times for local, regional, and distant metastases were 13.0, 14.0, and 8.0 months, respectively. The median survival times from local, regional, and distant failure to death were 10.5, 8.0, and 4.0 months, respectively. The 5-year overall survival rates of patients with and without distant organ metastases were 14.4% and 72.6%, respectively ( p < .001). Multivariate analyses showed that radiotherapy increased local recurrence-free and regional relapse-free survival. Patients with stage IV tumours had reduced distant metastasis-free and overall survival compared to patients with stage I–III tumours. Conclusions: Distant metastasis was mainly owing to failure. Radiotherapy and the disease stage were prognostic factors for survival.
