Objective To investigate the predictive value of baseline neutrophil-to-lymphocyte ratio (NLR) in the curative effect and prognosis of breast cancer patients treated with neoadjuvant chemotherapy.Methods The clinical data of 304 breast cancer patients received neoadjuvant chemotherapy in Beijing Cancer Hospital during 2010 were retrospectively analyzed.The correlations of baseline NLR with clinicopathological parameters of breast cancer patients were analyzed by Wilcox or Kruskal-Wallis tests,and the correlation of NLR with pathologic complete response (pCR) after neoadjuvant chemotherapy was analyzed by the binary logistic regression.The effect of clinic pathological parameters on the disease-free survival(DFS) of the patients was evaluated by the univariable and muhivariable Cox regression models.Results The medians of NLR in pCR + patients (n =62) and pCR-patients (n =242) were 1.76 and 1.72,respectively,and there was no significant difference between themn (P ＞ 0.05).Multivariate analysis indicated that the TNM stage (P ＜ 0.05) and pCR (P ＜ 0.05) were the independent risk factors influencing the prognosis of breast cancer patients.There was no significant correlation between NLR and 5-year DFS (HR=0.842,95％CI=0.566-1.255,P＞0.05).Condusion NLR lacks the predictive value in the curative effect and prognosis of breast cancer patients treated with neoadjuvant chemotherapy,while TNM stage and pCR are the independent risk factors influencing the prognosis of breast cancer patients.
