Data from population-based cohorts are scarce but warranted as a basis for randomized controlled treatment trials (RCTs). Our aim was to assess overall and histology subset-specific outcomes for SNM patients treated at a tertiary referral centre. METHODS: A retrospective, population-based, consecutive cohort of patients with SNMs diagnosed from 2001 through 2019 was examined. Outcome was analysed in relation to age, gender, site, stage, histopathology, and treatment. RESULTS: Two-hundred and twenty-six patients were identified, whereof 61% presented with stage IV disease. 80% completed treatment with curative intent, which comprised surgery with neoadjuvant (29%) or adjuvant (37%) radiotherapy, monotherapy with surgery (22%), definitive chemoradiotherapy (7%), or radiotherapy (5%). Median follow-up was 106 months. The 5- and 10-year overall survival rates were 57% and 35%, respectively. Median overall survival was 76 months (esthesioneuroblastoma: 147 months; adenocarcinoma: 117; salivary carcinoma: 88; mucosal melanoma: 69; squamous cell carcinoma: 51, undifferentiated carcinoma: 42; neuroendocrine carcinoma: 9; and NUT-carcinoma 5). The 5- and 10-year disease-free survival rates were 63% and 54%, respectively, and disease-specific survival 83% and 66%. Increasing age, stage IVB, melanoma histopathology, and treatment with definitive chemoradiotherapy emerged as significant independent prognostic risk factors for disease-specific mortality (p ≤ 0.001). CONCLUSION: The results indicate a seemingly good outcome in comparison to previous reports, particularly for mucosal melanoma, adenocarcinoma, and undifferentiated carcinoma. The study provides additi onal background for future RCTs focusing on histology subset-specific treatment for SNM. PMID:34510258 | DOI:10.1007/s00405-021-07057-0 View on the web Inoreader.
