COX-EGFR Regression analysis between COX-1 mRNA and EGFR mRNA showed a trend to significance in tumor tissue (p < 0.07).

Similarly, COX-2 mRNA was not significantly increased in tumor tissue versus mucosa tissue, which confirms our previous results [ 12 ], although there was a weak trend to increased COX-2 mRNA across tumor progression.
These important observations with different molecular size patterns of variable COX-2 proteins in tumor and mucosa tissues may be highly significant but must await further analytical evaluations.
