Among the specimens derived from omental metastatic disease (P) more samples showed moderate and strong fibronectin expression than among remaining (O & T) samples (61% & 36% vs. 58% & 21%; χ2 test, p = 0.024) (Figure 2A and Supplementary Figure S2A; Supplementary Table S1). This evidence concerns the gene FN1 and metastatic neoplasm.
