To evaluate and quantify the m7G-related patterns of PCa patients and accurately predict the BCR-free survival, we randomly selected 204 samples from TCGA-PRAD dataset as the training set to construct a prognostic model (m7Gscore) containing 9 hub m7G-related lncRNAs (KRTAP5-AS1, LINC02804, GMDS-DT, ZDHHC20-IT1, LINC02688, MSC-AS1, PVT1, PCAT7, and CASC19). The gene discussed is PVT1; the disease is posterior cortical atrophy.
