A longer time interval between surgery and adjuvant radiation has been associated with worse disease outcomes. How big is the effect for HPV+ head and neck cancer treated? In this retrospective study of 96 patients who had initial surgery, the median time to start RT was 38 days. There was no significant increase in the rate of locoregional recurrence among patients who had >6 weeks between surgery and RT compared to those who started treatment <6 weeks after surgery. | Niazi, Adv Radiat Oncol 2024
