Objective: Presence of neck nodal metastases in patients with primary head-and-neck cancer has traditionally been regarded as an adverse prognostic factor. We previously found that the presence of extracapsular spread does not influence prognosis in p16-positive oropharynx squamous cell carcinoma (OPSCC). Recently, lymph node ratio (LNR) (ratio of positive lymph nodes / total lymph nodes harvested) has been reported as a significant prognosticator in oral cavity SCC. In the present study, we aimed to determine the significance of advanced N-classification (N2b+), number of positive nodes, and LNR on recurrence and survival in OPSCC patients.

Methods: Retrospective review of 86 patients with primary OPSCC or SCC of unknown primary treated at our institution between 1998 and 2014. p16-immunohistochemistry was performed in all cases. LNR was categorised into LNR ................
