According to Table 1, the ARMCX1 level showed significant relation to age (P = 0.019), clinical stage (P = 0.041), and tumor grade (P = 0.003) as well as local invasion depth (P < 0.001) but not to sex, DM, or LNM in the GC cohort in TCGA, confirming the above results and further showing that ARMCX1 expression is correlated with depth of local invasion (P = 0.047), TNM stage (P = 0.026), and LNM (P = 0.026) rather than age, sex, tumor grade, or tumor size. This evidence concerns the gene ARMCX1 and gastric cancer.
