Factors predicting outcome after salvage treatment for stage IV oral squamous cell carcinoma: Evidence of the potential importance of the cyclooxygenase-2-prostaglandin E2 pathway.

Background: We determined the clinicopathological factors that predicted outcome after salvage treatment for stage IV oral squamous cell carcinoma (OSCC). Additionally, the prognostic significance of the cyclooxygenase-2 (COX-2)/microsomal prostaglandin-E synthase-1 (mPGES-1) pathway was evaluated.

Methods: Thirty-one patients who underwent salvage surgery were included.
