However, the correlation between NLR and the outcome of neoadjuvant chemotherapy (NAC) in breast cancer patients remains unclear.<h4>Methods</h4>NLR was evaluated in 177 patients with breast cancer treated with NAC with 5-fluorouracil, epirubicin, and cyclophosphamide, followed by weekly paclitaxel and subsequent curative surgery. The correlation between NLR and prognosis, including the efficacy of NAC, was evaluated retrospectively.<h4>Results</h4>NLR ranged from 0.5 to 10.6. Fifty-eight patients with low NLR (<3.0) had a higher pathological complete response (pCR) rate (p < 0.001) and were more frequently diAnnals of surgical oncology1104-10https://www.ebi.ac.uk/biostudies/studies/S-EPMC4773470biostudies-literaturePredictive Value of Neutrophil/Lymphocyte Ratio for Efficacy of Preoperative Chemotherapy in Triple-Negative Breast Cancer.PMC4773470Takashima TNoda SAsano YOnoda NKawajiri HHirakawa KOhsawa MKitagawa SKashiwagi SfalsePredictive Value of Neutrophil/Lymphocyte Ratio for Efficacy of Preoperative Chemotherapy in Triple-Negative Breast Cancer.<h4>Background</h4>The neutrophil/lymphocyte ratio (NLR) has been reportedly associated with prognosis in cancer patients by influencing both cancer progression and chemosensitivity.
