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. This evidence concerns the gene SSTR5 and central nervous system cancer.
