Consistent multimodality approach to oral cavity and high-risk oropharyngeal cancer in veterans.
2021
Abstract Purpose High-risk oropharyngeal squamous cell carcinoma (OPSCC) associated with tobacco exposure remains difficult to treat due to high rates of locoregional recurrence similar to oral cavity squamous cell carcinoma (OCSCC). Current NCCN guidelines allow for surgical management of this disease, but oncologic and functional data in the modern era remain scarce. We sought to compare and contrast oncologic and functional considerations for surgical management of OPSCC and OCSCC in a cohort of Veterans. Materials and methods We conducted a retrospective review of patients treated at the Michael E. DeBakey Veterans Affairs Medical Center between 2017 and 2020, treated using a homogenous, multi-modality algorithm. Results OPSCC tumors presented with a higher rate of perineural invasion (p Conclusion Surgical resection and free flap reconstruction of high-risk OPSCC generates oncologic outcomes comparable to OCSCC with comparable complication rates but a lower overall functional status. Reconstruction focused on rapid healing allows for high-rates of re-irradiation and minimal treatment delays. Level of evidence: level 4.
