Reduced lymph node size at end of radiation treatment correlates with overall survival. A Unadjusted Kaplan–Meier curve demonstrating overall survival for patients who experienced > 30% (red) and ≤ 30% reduction (blue) in the CC measurement from CT simulation to EOT CBCT (Binary Chi-Square HR 4.85, p = 0.028; continuous variable HR 1.07, 95% CI 1.02–1.15, p = 0.045). Patients with a > 30% decrease in lymph node size at end of treatment demonstrated improved overall survival. B Unadjusted Kaplan–Meier curve demonstrating overall survival for patients who experienced a CR (blue) and less than CR (PR, SD) (red) on 3-month post-treatment imaging
