This comparison showed an overlap of five genes (ETV4 (tumor non-malignant signature), STK32A, SPINK1, GOLT1A, KRT6A (adenocarcinomas—squamous cell carcinomas signature)) in the first case, and an overlap in one (KRT15) of the three most prominent genes in the second case. This evidence concerns the gene SPINK1 and adenocarcinoma.
