Abstract
Background: No risk-stratification strategies exist for patients with recurrent oropharyngeal cancer (OPC). Methods: Retrospective analysis using data from prospective NRG Oncology clinical trials RTOG 0129 and 0522. Eligibility criteria included known p16 status and smoking history, and locoregional/distant recurrence. Overall survival (OS) was measured from date of recurrence. Recursive partitioning analysis was performed to produce mutually exclusive risk groups. Results: Hundred and fifty-four patients were included with median follow-up after recurrence of 3.9 years (range 0.04–9.0). The most important factors influencing survival were p16 status and type of recurrence, followed by surgical salvage and smoking history (≤20 vs. >20 pack-years). Three significantly different risk groups were identified. Patients in the low-, intermediate-, and high-risk groups had 2-year OS after recurrence of 81.1% (95%CI 68.5–93.7), 50.2% (95%CI 36.0–64.5), and 20.8% (95%CI 10.5–31.1), respectively. Conclusion: Patient and tumor characteristics may be used to stratify patients into risk groups at the time of OPC recurrence.
