Response To Chemotherapy

Background The neutrophil–lymphocyte ratio (nlr) has been reported to correlate with patient outcome in several cancers, including breast cancer. We evaluated whether the nlr can be a predictive factor for pathologic complete response (pcr) after neoadjuvant chemotherapy (nac) in patients with triple-negative breast cancer (tnbc).Methods We analyzed the correlation between response to nac and various factors, including the nlr, in 87 patients with tnbc who underwent nac. In addition, we analyzed the association between the nlr and recurrence free survival (rfs) in patients with tnbc.Results Of the 87 patients, 25 (28.7%) achieved a pcr. A high Ki-67 index and a low nlr were significantly associated with pcr. The pcr rate was higher in patients having a high Ki-67 index (≥15%) than in those having a low Ki-67 index (35.7% vs. 0%, p = 0.002) and higher in patients having a low nlr (≤1.7) than in those having a high nlr (42.1% vs. 18.4%, p = 0.018). In multiple logistic analysis, a low nlr remained the only predictive factor for pcr (odds ratio: 4.274; p = 0.008). In the survival analysis, the rfs was significantly higher in the low nlr group than in the high nlr group (5-year rfs rate: 83.7% vs. 66.9%; log-rank p = 0.016).Conclusions Our findings that the nlr is a predictor of pcr to nac and also a prognosticator of recurrence suggest an association between response to chemotherapy and inflammation in patients with tnbc. The pretreatment nlr can be a useful predictive and prognostic marker in patients with tnbc scheduled for nac.

1041 Background: Early triple-negative breast cancer (TNBC) patients (p) without pathologic complete response (pCR) after neoadjuvant chemotherapy (NCT) have unsuccessful prognosis. Predictive factors for pCR are necessary in order to improve the treatment choice. The aims of the study are to determine the expression of different biomarkers (BM) in the initial biopsy (IB) of TNBC, to analyze the relationship between the BM expression and pCR, and to determine the expression changes of BM after NCT. Methods: We reviewed retrospectively the medical records of 49 TNBC p treated with NCT between 2001 and 2011 at two institutions. Expression of 14 BM in the IB and after NCT was independently analyzed by inmunohistochemistry by two pathology specialists. Staining intensity 0-1 + was considered as negative expression, and 2-3-4 + as positive. Ki 67>13% was interpreted as positive. Results: Forty-nine p with a median age of 47 years (27-79) were evaluated. Twenty-seven p (55%) had grade 3. Tumor stages were T1(2%), T2(26%), T3(39%), and T4(33%). 38p (77%) were node positive. Five p (10%) received anthracyclines and 42p (86%) anthracyclines plus taxanes. Fourteen p (29%) presented pCR, 27p (55%) partial response, 4p (8%) stable disease, 2p (4%) progressive disease, and 2p (4%) were not evaluable. The BM expression in the IB was: CD44 (88%), CK 5/6 (27%), EGFR ( 0%), Ki 67 (73%), Wt-1 (10%), p-Akt (24%), HER2 (19%), NY-ESO-1 (11%), MAGE A1 (0%), HER3 (14%), BRCA1 (84%), PTEN (12%), IGFR1 (12%) and AR (14%). Diferentially expressed BM in IB for p with and without pCR, respectively, were p-Akt 0/8(0%) vs 5/13(38%) p=0.11, CK 5/6: 4/9 (44%) vs 2/15 (13%) p=0.15 and Ki 67: 7/7(100%) vs 10/17(59%) p=0.06. The Table shows the BM expression before and after NCT for p without pCR. Conclusions: Tumor samples of TNBC show high expression of CD44, ki67, and BRCA1. Most of BM has a decrease in expression after NCT. CK 5/6, Ki 67, and p-Akt could be predictive factor for pCR, although larger prospective studies are needed. [Table: see text]

Complete Response

Systemic treatment for triple negative breast cancer (TNBC: negative for the expression of estrogen receptor and progesterone receptor and HER2 amplification) has been limited to chemotherapy options. Neoadjuvant chemotherapy induces tumor shrinkage and improves the surgical outcomes of patients with locally advanced disease and also identifies those at high risk of disease relapse despite today’s standard of care. By using pathologic complete response as a surrogate endpoint, novel treatment strategies can be efficiently assessed. Tissue analysis in the neoadjuvant setting is also an important research tool for the identification of chemotherapy resistance mechanisms and new therapeutic targets. In this paper, we review data on completed and ongoing neoadjuvant clinical trials in patients with TNBC and discuss treatment controversies that face clinicians and researchers when neoadjuvant chemotherapy is employed.
