Evaluating the expression of cyclooxygenase-2 enzyme by immunohistochemistry in normal and tumoral tissue before and after neoadjuvant chemoradiotherapy in patients with esophageal cancer in Khorasan Province

Conclusions: The results indicated that expression of COX-2 in tumoral tissues exceeds the expression of COX-2 in normal tissue of the baseline biopsy. Patients with a high expression of COX-2 in baseline tumor biopsies had less response to treatment of pathology compared to patients with lower expression of COX-2 in baseline tumor biopsies.
