This study investigates the relationship between NLR and pathological complete response (pCR) in Egyptian breast cancer patients receiving neoadjuvant chemotherapy. Materials and methods: Forty-six patients received preoperative neoadjuvant chemotherapy and underwent surgery; baseline complete blood counts were used to calculate NLR.

This study aims to explore the relationship of NLR with pathological complete response (pCR) in a cohort of Egyptian breast cancer patients who received neoadjuvant chemotherapy. Materials and Methods: Forty-six breast cancer females received preoperative neoadjuvant chemotherapy and then underwent surgery. All resected tumors were evaluated to determine the pathologic effect of the neoadjuvant chemotherapy. A complete blood count was carried out at baseline before beginning the neoadjuvant chemotherapy. The absolute count of neutrophils was divided by the absolute count of lymphocytes to calculate the NLR. Results: Of the study patients, 18 (39.1%) were considered to have a low NLR (NLR \u003C 1.76), and 28 (60.9%) were considered to have a high NLR (NLR ≥ 1.76) . Patients with a low NLR had 18-fold higher rates of pCR when compared to patients with a high NLR (OR 18.1; 95% CI (1.058–310.757); p = 0.046) . Conclusions: Our findings indicate that the pretreatment NLR is a pivotal predictor factor of the pathological complete response in Egyptian breast cancer patients treated with neoadjuvant chemotherapy.  \nKeywords: breast cancer; neoadjuvant chemotherapy; pathological complete response; neutrophil-to-lymphocyte ratio  \n1.
