ABSTRACT
OBJECTIVES:
Determine if intensive local therapy (i.e., local surgery or radiation) has a survival benefit for patients presenting with distantly metastatic oropharyngeal squamous cell carcinoma (OPSCC).METHODS:
Retrospective population-based cohort study of patients in the National Cancer Database presenting with distantly metastatic OPSCC. Overall survival (OS) was compared for patients receiving systemic therapy alone or in combination with local surgery or curative dose radiation, controlling for various clinicodemographic factors.RESULTS:
Between 2010 and 2015, 627 patients presented with newly diagnosed, metastatic OPSCC and an initial treatment course including systemic chemotherapy. Multivariable analysis demonstrated that local radiation therapy was independently associated with improved OS (OR 0.64, CI [0.51-0.81]); local surgery was not independently associated with improved OS (OR 0.99, CI [0.65-1.53]). Higher T stages were associated with worse OS (OR 1.69, CI [1.14-2.50] for T3 and OR 1.77, CI [1.22-2.58] for T4 compared to T1). HPV-positive (HPV+) tumors were associated with improved OS compared to HPV- (OR 0.79, CI [0.64-0.97]). Multiagent chemotherapy was associated with improved OS compared to single-agent (OR 0.78, CI [0.62-1.00]). The best survival for the entire cohort and for HPV+ patients was for radiation with systemic therapy and the worst survival for systemic therapy alone.CONCLUSIONS:
Curative dose local radiotherapy in addition to systemic therapy is associated with improved OS compared to systemic therapy alone in patients presenting with distantly metastatic OPSCC. There is not a significant survival benefit for local surgery in addition to systemic therapy in this patient population, regardless of HPV status.
