Taken together, we identified that several ncRNAs(miRNA-936, miRNA-1306-3p, miRNA-3185, miRNA- 6083, miRNA-659-3p, miRNA-6792-3p, lnc-ABCC5-2:1, lnc-MB21D1-3:5, lnc-PSCA-4:2, circASHL2, circCCDC9, circNHSL1 and cirMLLT10) could be useful to distinguish GC patients and also to predict the prognosis and prognosis of GC patients. This evidence concerns the gene PSCA and gastric cancer.
