Abstract
BACKGROUND The prognosis and the value of postmastectomy radiotherapy (PMRT) between post-chemotherapy ypT1-2ypN1 and de novo pT1-2N1 breast cancer (BC) remain controversial. We aimed to evaluate the prognostic differences and the effect of PMRT between the two patient subsets. METHODS Patients diagnosed with pT1-2N1M0 BC were identified between 2010 and 2018. The study endpoints were overall survival (OS), breast cancer-specific survival (BCSS), locoregional recurrence-free survival (LRFS), distant metastasis-free survival (DMFS) and disease-free survival (DFS). The chi-square test, Kaplan-Meier method and Cox regression analysis were used for data analysis. RESULTS Total number of 2103 pT1-2N1M0 BC patients were included in the study, including 270 post-chemotherapy (97 without PMRT, 173 with PMRT) and 1833 de novo cases (993 without PMRT, 840 with PMRT). No significant differences were found between post-chemotherapy ypT1-2ypN1 and de novo pT1-2N1 BC patients in 5-year OS (p = 0.068), BCSS (p = 0.054), LRFS (p = 0.241), DMFS (p = 0.104) or DFS (p = 0.08). PMRT did not improve any survival outcome in patients receiving neoadjuvant chemotherapy; however, the PMRT group had a better 5-year BCSS (97.0% vs. 95.8%, p = 0.033) in de novo pT1-2N1 BC. Cox multivariate analysis demonstrated that PMRT was a significant independent predictor of BCSS (HR 0.628; 95% CI, 0.403-0.978; p = 0.04) in de novo pT1-2N1 patients. CONCLUSIONS There seemed no survival difference in post-chemotherapy ypT1-2ypN1 and de novo pT1-2N1 BC patients with contemporary systemic therapy. In addition, PMRT might be exempted in patients with post-chemotherapy ypT1-2ypN1 BC, while not in patients with de novo pT1-2N1 BC.

Abstract
Abstract
Introduction Neoadjuvant chemotherapy (NAC) is the standard of care for locally advanced breast cancer. The achievement of pathological complete response (pCR) in response to NAC is of clinical significance as it correlates with improved long-term outcome. pCR rate varies with different chemotherapeutic agents and a higher rate may be associated with higher treatment cost and more toxicity.Triple-negative breast cancer (TNBC) has poorer prognosis than non-TNBC (estrogen receptor, progesterone receptor, and/or human epidermal growth factor receptor 2 expressing tumors), but patients achieving pCR may have similar outcome. We evaluated the response of TNBC after taxane and nontaxane-based NAC and its correlation with survival outcome.
Materials and Methods This was a retrospective study comparing the efficacy of “taxotere, Adriamycin and cyclophosphamide TAC” versus “cyclophosphamide, epirubicin, 5-fluorouracil/cyclophosphamide, Adriamycin, 5-fluorouracil (CEF/CAF)” NAC regimens in patients with locally advanced TNBC. The efficacy and safety of both the regimens were compared. Overall and disease-free survival were analyzed.
Results Two-hundred and forty-nine eligible patients were included and divided into two groups: taxane group receiving “TAC” regimen (123 patients) and nontaxane group receiving “CEF/CAF” regimen (126 patients). A higher pCR rate was achieved with taxane compared with nontaxane NAC (28 vs. 12%) (p = 0.0001). Although taxane addition did not lead to survival advantage for the entire group, significantly better survival rates were achieved for patients who had pCR compared with similar subgroup of patients in nontaxane group. Both the NAC regimens were well tolerable.
Conclusion Taxane-based NAC was although costlier than anthracycline-based regimen but was more effective, resulting in a higher pCR rate and an improved survival outcome in patients who achieved pCR.

Abstract
Background Our study aimed to compare the efficacy and safety of anthracycline plus taxane (AT)-based neoadjuvant chemotherapy (NAC) with or without cyclophosphamide in the treatment of breast cancer. Methods We searched PubMed, Embase, Web of Science and the Cochrane Library for randomized controlled studies comparing the efficacy and safety of AT-based NAC with or without cyclophosphamide in breast cancer patients. Results Four eligible studies with 2,302 individuals were ultimately included in the quantitative analysis. After applying the AT-based NAC regimen, the overall rates of pathologic complete response (pCR) and breast conserving surgery in all included subjects were 26.5% and 70.6%, respectively. The rates of pCR [risk ratio (RR): 1.35; 95% CI: 0.75, 2.45; P=0.32], breast-conserving surgery (RR: 1.07; 95% CI: 0.97, 1.19; P=0.17) and clinical response (RR: 1.08; 95% CI: 0.97, 1.19; P=0.15) in patients in the cyclophosphamide group were similar to those in the control group. However, participants in the cyclophosphamide group had a lower no clinical response rate than those in the control group (RR: 0.72; 95% CI: 0.60, 0.87; P<0.001). Subjects in the cyclophosphamide group had significantly lower rates of infection (RR: 0.57; 95% CI: 0.41, 0.79; P<0.001) and diarrhea (RR: 0.46; 95% CI: 0.30, 0.68; P<0.001) and higher rates of thrombocytopenia (RR: 3.38; 95% CI: 1.96, 5.84; P<0.001), sensory/motor neuropathy (RR: 1.57; 95% CI: 1.03, 2.39; P=0.03) and nausea/vomiting (RR: 1.51; 95% CI: 1.11, 2.06; P=0.009) than those in the control group. Conclusions The AT-based NAC regimen with or without cyclophosphamide had similar clinical outcomes in breast cancer patients. The addition of cyclophosphamide might increase the risks of thrombocytopenia, sensory/motor neuropathy and nausea/vomiting.

Abstract
Background To identify whether a stem cell biomarker, KLF4, may predict the pathologic tumor response to neoadjuvant chemotherapy for patients with locally advanced breast cancer. Methods Twelve locally advanced breast cancer patients who achieved pathologic complete remission (pCR) after neoadjuvant chemotherapy were identified and for each, three non-pCR breast cancer patients – matched for age, clinical tumor–node–metastasis stage, and neoadjuvant chemotherapy cycles – were selected. The relationship between KLF4 expression in the core needle biopsied cancer tissue and patient pCR rate was assessed using univariate and multivariate analysis. Results Receiver operating characteristic curve analysis showed that the patients with a histoscore of KLF4 expression >0.18 had a lower pCR rate. Multivariable analysis showed that higher KLF4 expression (odds ratio 0.013; 95% confidence interval 0.013–0.444; P=0.004) was independently correlated with a lower pCR rate after neoadjuvant chemotherapy. Conclusion KLF4 overexpression was associated with lower pCR in locally advanced breast cancer patients undergoing neoadjuvant chemotherapy. This study suggests that KLF4 may serve as a predictor for pCR in patients with breast cancer after neoadjuvant chemotherapy.
