【 摘 要 】

Background: The aim of the study was to review a local treatment protocol for sinonasal mucosal melanoma (SNMM) focusing on triple modality treatment (TMT), that is, neoadjuvant concomitant chemoradiotherapy (CRT) and surgery. Methods: In a retrospective design, data on clinical presentation, treatment, and survival were retrieved for 22 consecutive patients from a tertiary referral center. Results: The mean overall survival (OS) for all patients (3 stage III, 16 stage IVA, and 3 stage IVB) was 62 months, and the 5-year OS rate 50%. Four of the 22 patients received treatment with palliative intention. Of the 18 patients who received treatment with curative intention, patients with stage IVA disease who received TMT (n = 10) had a 5-year OS of 70% and 10-year OS of 20%. The median disease-free survival for these patients was 51 months compared with 9 months for stage IVA not receiving TMT (n = 4). Conclusion: A seemingly favorable survival outcome for a disease with characteristically poor prognosis was observed. The lead finding was a high survival rate (70% 5-year OS) for stage IVA patients who received neoadjuvant TMT. The observations suggest the possibility that patients with advanced SNMM (stage IVA) might benefit from concomitant CRT before surgery by delaying the onset of local recurrences and distant metastases. Level of Evidence: Level 4, case series (with or without comparison).
