BACKGROUND: Whether extra-nodal extension (ENE+) and surgical margin positivity (margin+) are poor prognostic factors in HPV-associated (HPV+) oropharyngeal carcinoma (OPC) remains uncertain.
RESULTS: Our study evaluated if microscopic ENE+ and/or margin+ are associated poorer recurrence free survival (RFS) and overall survival (OS) in HPV+ OPC. Patients were classified as high risk (ENE+ and/or margin+) or low risk (ENE- and margins-). Of a total of 176 patients HPV+ OPC, 81 underwent primary surgery and dad data on ENE and margin status. There was no statistically significant difference in RFS (p = 0.35) or OS (p = 0.13) for high-risk versus low-risk groups. Ongoing smoking (p = 0.023), alcohol use (p = 0.044) and advanced stage (p = 0.019) were associated with higher risk of recurrence. Only advanced stage (p-value <0.0001) was associated poorer overall survival.
CONCLUSIONS: The presence of ENE+ and/or margin+ was not an independent predictor of poor RFS or OS in HPV+ OPC.
