Here we focused on the impact of negative lymph node (NLN) count on the prediction of value of LNR in breast cancer survival.
Methods: Of 929 invasive breast cancer patients were enrolled in our retrospective study. We use Kaplan-Meier to calculate the 5-year overall survival (OS) according to different clinicopathologic parameters. The prediction value of NLN count and LNR in OS was examined.
Results: The optimal cutoff of NLN count was designated as 9. Five-year OS was 77.0% and 95.0% in patients with NLN of 0–9 and ≥10, respectively (P},
