Among HNSCC, those originating in the hypopharynx have the worst prognosis. The histone demethylase LSD1 has been shown to promote cancer initiation, progression, and relapse through various mechanisms and is upregulated in many cancer tissues. LSD1 physically interacts with SNAIL and is required for SNAIL mediated transcriptional repression. Previous studies of the prognostic value of LSD1 in HNSCC have been limited in their analysis of sub-sites, and a correlation between LSD1 and SNAIL has not been shown in HNSCC patient samples. Here we used a large, representative, and clinically well-characterized cohort of 339 HNSCC patients to investigate the co-expression of LSD1 and SNAIL and their prognostic value in all HNSCC using immunohistochemical staining. Elevated LSD1 expression correlated with advanced tumor stage and poor progression-free survival (PFS) in HNSCC originating in the hypopharynx. Overexpression of the transcription factor SNAIL independently correlated with worse overall survival (OS) and PFS in HNSCC in general and prominently in tumors of the hypopharynx. Furthermore, increased LSD1 expression significantly correlated with elevated SNAIL expression in patient samples. Therefore, the presented data implicates LSD1 and SNAIL as independent prognostic biomarkers.<\/jats:p>","DOI":"10.3390\/ijms23095075","type":"journal-article","created":{"date-parts":[[2022,5,3]],"date-time":"2022-05-03T08:26:35Z","timestamp":1651566395000},"page":"5075","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Elevated LSD1 and SNAIL Expression Indicate Poor Prognosis in Hypopharynx Carcinoma"],"prefix":"10.3390","volume":"23","author":[{"given":"Justus","family":"Bottner","sequence":"first","affiliation":[{"name":"Institute of Pathology, University of Luebeck and University Hospital Schleswig-Holstein, Campus Luebeck, 23538 Luebeck, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1262-6572","authenticated-orcid":false,"given":"Julika","family":"Ribbat-Idel","sequence":"additional","affiliation":[{"name":"Institute of Pathology, University of Luebeck and University Hospital Schleswig-Holstein, Campus Luebeck, 23538 Luebeck, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luise","family":"Klapper","sequence":"additional","affiliation":[{"name":"Institute of Pathology, University of Luebeck and University Hospital Schleswig-Holstein, Campus Luebeck, 23538 Luebeck, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tobias","family":"Jagomast","sequence":"additional","affiliation":[{"name":"Institute of Pathology, University of Luebeck and University Hospital Schleswig-Holstein, Campus Luebeck, 23538 Luebeck, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna-Lena","family":"Lemster","sequence":"additional","affiliation":[{"name":"Institute of Pathology, University of Luebeck and University Hospital Schleswig-Holstein, Campus Luebeck, 23538 Luebeck, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sven","family":"Perner","sequence":"additional","affiliation":[{"name":"Institute of Pathology, University of Luebeck and University Hospital Schleswig-Holstein, Campus Luebeck, 23538 Luebeck, Germany"},{"name":"Institute of Pathology, Research Center Borstel, Leibniz Lung Center, 23845 Borstel, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Idel","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, University of Luebeck and University Hospital Schleswig-Holstein, Campus Luebeck, 23538 Luebeck, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jutta","family":"Kirfel","sequence":"additional","affiliation":[{"name":"Institute of Pathology, University of Luebeck and University Hospital Schleswig-Holstein, Campus Luebeck, 23538 Luebeck, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"394","DOI":"10.3322\/caac.21492","article-title":"Global Cancer Statistics 2018: GLOBOCAN Estimates of Incidence and Mortality Worldwide for 36 Cancers in 185 Countries","volume":"68","author":"Bray","year":"2018","journal-title":"CA A Cancer J.
