The overall survival of the two groups of gastric cancers with CDX2 induction and SOX2-maintained expression or SOX2 mRNA suppression did not differ significantly, with the survival curves of the two groups virtually overlapping, suggesting that, despite being associated with differences in genomic lesions, SOX2 mRNA levels did not convey prognostic information (Log Rank p = 0.81, Figure 7). This evidence concerns the gene SOX2 and gastric cancer.
