Patients and Methods. Pre-treatment NLR was retrospectively analyzed in 475 BC women prospectively followed for a mean time of 3.8 years. The optimal NLR cutoff, identified by ROC analysis, was set at 2. Results: Elevated pre-treatment NLR was associated with worse disease-free survival (DFS) (HR=2.28) and overall survival (OS) (HR=3.39). The prognostic value of NLR was mostly evident in stage I BC (HR for DFS=2.89; HR for OS=1.30), in whom NLR significantly stratified patients who developed distant metastasis (HR= 4.62), but not local recurrence. Conclusion: NLR might provide important information in risk stratification, especially in stage I BC patients in whom the presence of a high NLR might raise the question as to whether they should be more aggressively managed.
