Moderate to strong (elevated) expression of COX-2 protein is observed in approximately one third of early breast cancers, and COX-2 expression is associated with a large tumor size, a high histological grade, a negative HR status, a high cell proliferation rate, high p53 expression, presence of HER-2 amplification, and unfavorable survival [22]. The gene discussed is PTGS2; the disease is neoplasm.
