Furthermore, compared with the tumor tissues, HOXA11 expression was lower in peritumor tissues (training cohort: P<0.0001; validation cohort: P<0.0001; Figure 7B and Figure S4A), this tendency had also been validated by the mRNA expression level of HOXA11 in GSE13861, GSE13911 and TCGA database. Here, HOXA11 is linked to neoplasm.
