Further, we established the prognostic model of six HRlncRNAs (LUCAT1, MIR4435-2HG, LINC01711, AP000695.2, ADAMTS9-AS2, and AC087521.1) by means of univariate and multivariate cox and lasso regression analyses to explore the potential influence in pan-cancer of the digestive system. The gene discussed is ADAMTS9; the disease is cancer.
