BackgroundThe lymphocyte-to-monocyte ratio (LMR) has been used as a parameter reflecting systemic inflammation in several tumors, and is reportedly associated with prognosis in cancer patients. In this study, we evaluated the predictive value of LMR for progression and chemosensitivity in breast cancer patients treated with preoperative chemotherapy.MethodsLMR was evaluated in 239 patients with breast cancer treated with neoadjuvant chemotherapy (NAC) with 5-fluorouracil, epirubicin, and cyclophosphamide, followed by weekly paclitaxel with or without trastuzumab, and subsequent curative surgery. The correlations between LMR and clinicopathological features, prognosis, and pathological complete response (pCR) rate of NAC were evaluated retrospectively. We also evaluated the predictive value of neutrophil-to-lymphocyte ratio (NLR), and compared the predictive values of LMR and NLR.ResultsWe set 6.00 as the cut-off level for LMR based on the receiver operating characteristic (ROC) curve. A total of 119 patients (49.8%) were classified in the high-LMR group and 120 (50.2%) were classified in the low-LMR group. The low-LMR group had significantly worse disease-free survival rate (DFS) in all patients (p = 0.005) and in triple-negative breast cancer patients (p = 0.006). However, there was no significant correlation between LMR and pCR. Multivariate analysis showed that low LMR was an independent risk factor for DFS (p = 0.008, hazard ratio = 2.245). However, there was no significant difference in DFS (p = 0.143, log-rank) between patients in the low- and high-NLR groups.ConclusionsLMR may be a useful prognostic marker in patients with breast cancer.Electronic supplementary materialThe online version of this article (10.1186/s12885-018-5051-9) contains supplementary material, which is available to authorized users.

Thoracoacromial venous supercharging using the ipsilateral superficial inferior epigastric vein is a valuable method which considerably secures the DIEP free flap in breast reconstruction although it lengthens the operative procedure. EBM level: Level III.

Abstract. Background/Aim: Recent interest has focused on the significance of tumor-infiltrating lymphocytes (TILs) on the efficacies and outcomes of the treatment in breast cancer (BC respectively). Multivariable analysis also showed that high-TIL status was an independent factor predicting favorable prognosis (hazard ratio(HR)=0.24, p=0.023 and HR=0.13, p=0.036

BackgroundThe tumor immune environment not only modulates the effects of immunotherapy, but also the effects of other anticancer drugs and treatment outcomes. These immune responses can be evaluated with tumor-infiltrating lymphocytes (TILs), which has frequently been verified clinically. On the other hand, residual cancer burden (RCB) evaluation has been shown to be a useful predictor of survival after neoadjuvant chemotherapy (NAC). In this study, RCB and TILs evaluations were combined to produce an indicator that we have termed “RCB-TILs”, and its clinical application to NAC for breast cancer was verified by subtype-stratified analysis.MethodsA total of 177 patients with breast cancer were treated with NAC. The correlation between RCB and TILs evaluated according to the standard method, and prognosis, including the efficacy of NAC, was investigated retrospectively. The RCB and TILs evaluations were combined to create the “RCB-TILs”. Patients who were RCB-positive and had high TILs were considered RCB-TILs-positive, and all other combinations were RCB-TILs-negative.ResultsOn multivariable analysis, being RCB-TILs-positive was an independent factor for recurrence after NAC in all patients (p < 0.001, hazard ratio = 0.048), triple-negative breast cancer (TNBC) patients (p = 0.018, hazard ratio = 0.041), HER2-positive breast cancer (HER2BC) patients (p = 0.036, hazard ratio = 0.134), and hormone receptor-positive breast cancer (HRBC) patients (p = 0.002, hazard ratio = 0.081).ConclusionsThe results of the present study suggest that RCB-TILs is a significant predictor for breast cancer recurrence after NAC and may be a more sensitive indicator than TILs alone.Electronic supplementary materialThe online version of this article (doi: 10.1186/s12885-017-3927-8) contains supplementary material, which is available to authorized users.
