ObjectiveTo characterize treatment delays in oropharyngeal cancer treated with radiation in a national sample, identify factors associated with delays, and associate treatment delays with survival.Materials and MethodsWe included adults in the National Cancer Database treated for oropharyngeal cancer with primary radiation or chemoradiation 2010–2013. We characterized diagnosis-to-treatment initiation, radiation treatment duration, and diagnosis-to-treatment end intervals as medians. We examined delays for association with patient, tumor, and treatment characteristics and with overall survival with multivariable logistic and Cox proportional hazards regression, respectively.Results4089 patients were included; 12% received radiation alone and 88% chemoradiation. The incidence of human papilloma virus-associated tumors was 64%. Median durations of diagnosis-to-treatment initiation, radiation duration, and diagnosis-to-treatment end were 35, 50, and 87 days, respectively. Human papilloma virus-positive tumors were linked to decreased delays in radiation treatment duration and diagnosis-to-treatment end (OR = 0.72 (0.60–0.85), p < 0.001 and OR = 0.79 (0.66–0.95), p = 0.010, respectively). Delays in radiation treatment duration and diagnosis-to-treatment end were negatively associated with overall survival (HR = 1.23 (1.03–1.47), p = 0.024 and 1.24 (1.04–1.48), p = 0.017, respectively). When examined separately, radiation duration remained associated with decreased overall survival in patients with human papilloma virus-negative (HR = 1.29 (1.03–1.63), p = 0.030) but not human papilloma virus-positive tumors (HR = 1.17 (0.89–1.54), p = 0.257).ConclusionThese median durations can serve as national benchmarks. Diagnosis-to-treatment end interval is associated with overall survival in all patients, and radiation treatment duration in patients with human papilloma virus-negative tumors. These intervals could be considered quality indicators for oropharyngeal squamous cell carcinoma treated with primary radiation or chemoradiation.
