Epidemiology data regarding mucosal melanomas in Brazil is scarce, hence the motivation to conduct this research paper. The \u03c72 test was used to compare categorical variables. Forward stepwise logistic regression method was used in the multivariate analysis to identify independent predictors of early death. A total of 801 patients were included in the analysis. Surgical resection is frequently the first approach to primary tumours (65.3%), even though the utility of lymph node surgery and radiation therapy is not well established. Advanced stage was observed in more than two thirds of patients. Early death was observed in 28.3%. MM cases with regional or distant metastases as well as those located in unusual locations had almost 4 times more risk for early death. Besides that, MM located in lips, oral cavity and pharynx and those receiving chemotherapy had 2 times more risk of early death.<\/jats:p>","DOI":"10.1038\/s41598-019-57253-6","type":"journal-article","created":{"date-parts":[[2020,1,16]],"date-time":"2020-01-16T11:03:28Z","timestamp":1579172608000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Epidemiological profile of mucosal melanoma in Brazil"],"prefix":"10.1038","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0089-1910","authenticated-orcid":false,"given":"Daniel","family":"Cohen Goldemberg","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreia Cristina","family":"de Melo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Livia Cristina","family":"de Melo Pino","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luiz Claudio Santos","family":"Thuler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,1,16]]},"reference":[{"key":"57253_CR1","doi-asserted-by":"publisher","first-page":"96","DOI":"10.1016\/j.ad.2014.04.012","volume":"106","author":"R Ballester Sanchez","year":"2015","unstructured":"Ballester Sanchez, R., de Unamuno Bustos, B., Navarro Mira, M. & Botella Estrada, R. melanoma: an update.
