| Abstract |
A high neutrophil-to-lymphocyte ratio (NLR) may be related to increased mortality in patients with lung, colorectal, stomach, liver, and pancreatic cancer. To date, the utility of NLR to predict the response to neoadjuvant chemotherapy (NAC) has not been studied. The aim of our study was to determine whether the NLR is a predictor of response to NAC and to investigate the prognostic impact of the NLR on relapse-free survival (RFS) and breast cancer-specific survival (BCSS) in patients with breast cancer who received NAC. We retrospectively studied patients who received NAC and subsequent surgical therapy for stage II-III invasive breast carcinoma at Sun Yat-sen Memorial Hospital between 2001 and 2010. The correlation of NLR with the pathological complete response (pCR) rate of invasive breast cancer to NAC was analyzed. Survival analysis was used to evaluate the predictive value of NLR. A total of 215 patients were eligible for analysis. The pCR rate in patients with lower pretreatment NLR (NLR < 2.06) was higher than those with higher NLR (NLR ≥ 2.06) (24.5 % vs.14.3 %, p < 0.05). Those patients with higher pretreatment NLR (NLR ≥ 2.1) had more advanced stages of cancer and higher disease-specific mortality. Through a multivariate analysis including all known predictive clinicopathologic factors, NLR ≥ 2.1 was a significant independent parameter affecting RFS (HR: 1.57, 95 % CI: 1.05-3.57, p < 0.05) and BCSS (HR: 2.21, 95 % CI: 1.01-4.39, p < 0.05). Patients with higher NLR (NLR ≥ 2.1) before treatment showed significantly lower relapse-free survival rate and breast cancer-specific survival rate than those with lower NLR (NLR <2.1) (log-rank p = 0.0242 and 0.186, respectively). Pretreatment NLR < 2.06 is associated with pCR rate, suggesting that NLR may be an important factor predicting the response to NAC in breast cancer patients. NLR is an independent predictor of RFS and BCSS in breast cancer patients with NLR ≥ 2.1 who receive NAC. We suggest prospective studies to evaluate NLR as a simple prognostic test for breast cancer. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 14 June 2016.
All research outputs
#14,851,946
of 22,873,031 outputs
Outputs from BMC Cancer
#3,677
of 8,323 outputs
Outputs of similar age
#198,382
of 334,143 outputs
Outputs of similar age from BMC Cancer
#36
of 94 outputs
Altmetric has tracked 22,873,031 research outputs across all sources so far. This one is in the 33rd percentile – i.e., 33% of other outputs scored the same or lower than it.
So far Altmetric has tracked 8,323 research outputs from this source. They receive a mean Attention Score of 4.3. This one has gotten more attention than average, scoring higher than 50% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 334,143 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 37th percentile – i.e., 37% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 94 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 56% of its contemporaries.
