Article Title Similar survival outcome after endoscopic and open approaches for sinonasal mucosal melanoma
Abstract BACKGROUND: To describe a cohort of sinonasal mucosal melanoma (SNMM) patients, and to assess if choice of surgical approach (open versus endoscopic) has impact on survival.
METHODOLOGY: Adequate data on clinical presentation, treatment, and recurrence pattern were available for 58 consecutive patients treated for SNMM at the Helsinki University Hospital (HUH) between 1983 and 2016.
RESULTS: The 5-year disease-specific survival (DSS) was 27% and overall survival 25% for the whole cohort. The 3-year DSS for patients treated with curative intent with endoscopic surgery was comparable to open surgery (56% and 51%, respectively). Patients with tumours arising from the paranasal sinuses and patients with Stage IV disease had significantly worse prognosis compared with other locations and Stage III patients. All patients who had disease persistence at three months after primary treatment succumbed to SNMM. Post-operative radiotherapy did not affect survival significantly, but a trend towards improved local control was observed.
CONCLUSIONS: Local control after endoscopic surgery was comparable to open surgery. Small tumours without local or locoregional spread had improved prognosis, independent of surgical approach. Disease persistence after treatment with curative intent led to death invariably.
