Among these above four lncRNAs in the risk score, decreased LINC00261 was identified associated with poor prognosis and metastasis in Gastric Cancer (GC).37 Moreover, LINC00261 was found related to cell growth, migration, cell proliferation, and cell apoptosis in endometriosis and choriocarcinoma.38, 39 Furthermore, multivariate analyses revealed that expression of CDKN2B‐AS1 could be an independent predictor for OS (P = .036) in GC.40 The other two lncRNAs (TRELM3P and GBP1P1) were not reported till now. The gene discussed is CDKN2B; the disease is endometriosis.
