In univariate analyses, high PAT4 levels (P=0.01) as well as high tumour stage (P<0.01), tumour stage score (P<0.01), the presence of bowel perforation (P=0.02), neural invasion (P<0.01), nodal (P<0.01) and synchronous metastasis (P<0.01) significantly correlated with shorter relapse-free survival (Supplementary Table S2). Here, SLC36A4 is linked to neoplasm.
