ObjectivesSinonasal mucosal melanoma is a rare disease, representing 4% of nasal cavity and paranasal sinus malignancies. The aim of this study was to assess the clinical characteristics, progression and treatment of this disease and to identify prognostic factors.Material and methodsThis retrospective review presents a cohort of 44 patients treated for a melanoma arising from the nasal cavity and paranasal sinuses, in the ENT Head and Neck Surgery Department of the University Hospital of Nantes (France) between 1988 and 2015.ResultsMean age at diagnosis was 71.2 years. The main signs at diagnosis were epistaxis and unilateral nasal obstruction. 25% of patients were initially classified as T4. Surgical treatment was performed in 42 patients. Postoperative radiotherapy was performed in 19 cases and adjuvant immunotherapy in 14 cases. Mean follow-up was 50 months. Cumulative overall survival was 71.5% at 1 year and 33% at 5 years. Clinically, headache, facial pain and trigeminal V2 nerve anesthesia were significant factors for poor prognosis. Exclusively nasal involvement was a factor for better overall survival than sinus involvement. Adjuvant radiation therapy showed a non-significant trend toward improved local control.ConclusionsMucosal melanoma of the sinonasal cavities has poor prognosis due to high metastatic potential. Surgical resection followed by radiation therapy is the main treatment. There is no consensus regarding new systemic adjuvant treatments in this indication, unlike for primary cutaneous melanoma.
