To investigate the prognostic potentials of MUC family genes for STAD, we performed KM survival analysis exclusively on STAD samples from TCGA with R package survival. It was found that the expression levels of EMCN (MUC14) and MUC15 individually showed significant correlations with both OS and DFS, and MCAM (MUC18) was significant only with OS (Table 2). Here, MCAM is linked to gastric adenocarcinoma.
