ZNF667 and esophageal cancer: The prognostic significance of these three lncRNAs was shown in several cancer types, such as ZNF667-AS1 in glioma [70] and SEMA3B-AS1 and SSTR5-AS1 in esophageal cancer [71,72], but we report for the first time the prognostic potential of these three lncRNAs as overall survival markers in EOC.
