To summarize, we have constructed an m7G-associated lncRNA prognostic model involving five lncRNAs (KRT7-AS, USP30-AS1, ZFHX4-AS1, ACAP2-IT1, and TWSG1-DT), where the guiding value of this model for OS in ovarian cancer patients was measured and confirmed, as well as it can be functioned as an independent prognostic factor for OC patients. This evidence concerns the gene ZFHX4 and ovarian cancer.
