Cumulative incidence of locoregional recurrence by recurrence score (RS) and nodal status. A) Patients with one to three positive nodes (n = 722). Ten-year cumulative incidence of locoregional recurrence (LRR) was 3.2% (95% CI = 1.5% to 5.9%), 5.1% (95% CI = 2.8% to 8.4%), and 7.9% (95% CI = 4.7% to 12.1%) for low, intermediate, and high RS, respectively (P = .12). B) Patients with four or more positive nodes (n = 343). Ten-year cumulative incidence of LRR was 3.5% (95% CI = 1.1% to 8.0%), 11.6% (95% CI = 6.5% to 18.4%), and 20.3% (95% CI = 13.2% to 28.3%) for low, intermediate, and high RS, respectively (P = .001). Gray’s k-sample test was used, and all P values were one-sided. LRR = locoregional recurrence; RS = recurrence score.
