To assess whether the expression of LCN2, SLC22A17, and MMP9 genes was predictive of the survival outcome in cancer patients, the UCSC Xena tool was used to obtain the OS and PFI data according to their gene expression in all tumor types included in the TCGA PAN-CANCER cohort (Supplementary Table S9). The gene discussed is SLC22A17; the disease is neoplasm.
