We discovered a significant difference in the median values of HMGA2 mRNA expression according to tumour histology (p = 0.003) with a considerably higher median fold change value in the squamous cell carcinoma group (70.6 fold) compared to adenocarcinomas (13.1 fold) and others (5.8 fold) (Table 2). Here, HMGA2 is linked to adenocarcinoma.
