In the univariate analysis, there was a lower recurrence rate in stages 1 and 2 in comparison with stage 3 (HR: 0.32, 95% CI: 0.15–0.66, and HR: 0.42, 95% CI: 0.28–0.64; P=0.002), grade 2 tumors in comparison with grade 3 tumors (HR: 0.57, 95% CI: 0.38–0.86; P=0.008), hormone receptor positive tumors in comparison with hormone receptor negative tumors (HR: 0.61, 95% CI: 0.38–0.97; P=0.04), and tumor size of ≤2.5 cm in comparison with a tumor size of >3 cm (HR: 0.58, 95% CI: 0.36–0.92; P=0.021). This evidence concerns the gene NR4A1 and neoplasm.
