Here, the investigators will develop a clinicopathomic assay from biomarkers obtained from digital pathologies of resected whole-mount oral cavity and oropharyngeal squamous cell carcinoma (OCSCC and OPSCC) specimens with the goal of administering personalized novel image-guided therapies immediately after primary surgical management in OCSCC and OPSCC patients. The primary aim is to determine the association between clinicopathomic biomarkers and LRR. The secondary aim is to develop a clinicopathomic risk score (assay) such that a decision-support tool can be used by physicians for measuring the benefit of additional therapies (i.e. conventional chemotherapy +/- radiation or administering dose-escalated chemoradiation) in the adjuvant setting to reduce LRR rates.
