Objectives/Hypothesis In this study, we retrospectively reviewed medical records of patients who underwent surgery for p16+ oropharyngeal cancer and analyzed the prognostic implications of pathologic lymph node (LN) status, including number of metastatic LNs, LN ratio, and location of metastatic LNs. Study Design Retrospective case series. Methods We retrospectively reviewed data on patients diagnosed with p16+ oropharyngeal cancer. Results The study population consisted of 159 males and 29 females with a mean age of 57.2 years. The primary tumor sites were tonsils (n = 160), base of the tongue (n = 24), and soft palate (n = 4). Only recurrence‐free survival (RFS) showed a significant correlation with contralateral LN metastasis on multivariate analysis. On Kaplan‐Meier analysis, 5‐year RFS was 92.4% in patients without contralateral LN metastasis and 68.8% in patients with contralateral LN metastasis. Conclusions Among pathologic LN status in p16+ oropharyngeal cancer, only contralateral LN metastasis showed prognostic significance in disease recurrence of p16+ oropharyngeal squamous cell carcinoma patients.
