In the following analysis, the outcome of the Kaplan–Meier analysis suggested that the high expression of LINC00460, miR205HG, AC103563, and RP11-186F10.2 was strongly associated with poor prognosis in gastric adenocarcinoma tissues, and in turn, RP11-1143G9.5 high expression was closely related to a good prognosis. The gene discussed is LINC00460; the disease is gastric adenocarcinoma.
