Introduction: In a previous study our group showed a beneficial effect of targeted intraoperative radiotherapy (TARGIT-IORT) as an intraoperative boost on overall survival after neoadjuvant chemotherapy (NACT) compared to an external boost (EBRT). In this study we present the results of a detailed subgroup analysis of the hormone receptor (HR)-positive HER2-negative patients. Methods: In this cohort study involving 46 patients with HR-positive HER2-negative breast cancer after NACT, we compared the outcomes of 21 patients who received an IORT boost to those of 25 patients treated with an EBRT boost...

BACKGROUND: Tumour-infiltrating lymphocytes (TILs) are predictive for response to neoadjuvant chemotherapy in triple-negative breast cancer (TNBC) and HER2-positive breast cancer, but their role in luminal breast cancer and the effect of TILs on prognosis in all subtypes is less clear. Here, we assessed the relevance of TILs for chemotherapy response and prognosis in patients with TNBC, HER2-positive breast cancer, and luminal-HER2-negative breast cancer. METHODS: Patients with primary breast cancer who were treated with neoadjuvant combination chemotherapy were included from six randomised trials done by the German Breast Cancer Group...

The identification of informative biomarkers that could predict the treatment response is particularly important in the triple-negative (TN) breast cancer, which is characterized by biological diversity. The aim of this study was to investigate the impact of vascular endothelial growth factor receptor (VEGFR2) expression and its gene polymorphisms on pathologic complete response (pCR) to neoadjuvant chemotherapy (NCT) in Russian patients with TN breast cancer. We performed a retrospective analysis of 70 women with operable TN breast cancer, who underwent NCT with 5-fluorouracil, adriamycin, and cyclophosphamide (FAC) or cyclophosphamide, adriamycin, and capecitabine (CAX) between 2007 and 2013...

BACKGROUND: Breast conservation therapy (BCT) consists of breast conservation surgery (BCS) and radiotherapy (RT). Neoadjuvant chemotherapy (NACT) can downstage tumors, broadening BCS eligibility in patients requiring mastectomy. However, tumor downstaging does not obviate need for RT. This study evaluated factors that predict RT omission after NACT and BCS. METHODS: The National Cancer Database was queried for women with unilateral, clinical stage II-III breast cancer, treated with NACT and BCS between 2008 and 2012...

Background: Pathological complete response (pCR) is associated with improved prognosis in triple-negative breast cancer (TNBC). The optimal chemotherapy regimen is unclear. Weekly nab-paclitaxel vs conventional paclitaxel or addition of carboplatin to anthracycline-taxane results in higher pCR rates with uncertain survival impact. We evaluated carboplatin vs gemcitabine with a nab-paclitaxel backbone as a short 12-week A-free regimen with a focus on early response. Methods: Patients with TNBC (estrogen receptor/progesterone receptor < 1%, human epidermal growth factor receptor 2-negative, cT1c-cT4c, cN0/+) were randomly assigned to A: nab-paclitaxel 125 mg/m2/gemcitabine 1000 mg/m2 d1,8 three times weekly (q3w); vs B: nab-paclitaxel 125 mg/m2/carboplatin AUC2 day 1,8 q3w...

AIM: To determine the value of mammography and breast ultrasound (US) in predicting outcomes in HER2 positive breast cancer patients (pts) within Neo-ALTTO trial. PATIENTS AND METHODS: Mammography and US were required at baseline, week 6 and surgery. Two independent blinded investigators reviewed the measurements and assigned the corresponding response category. Pts showing complete or partial response according to RECIST (v1.1) were classified as responders. The association between imaging response at week 6 or prior to surgery was evaluated with respect to pathological complete response (pCR) and event-free Survival (EFS)...

A minority of breast cancer (BC) patients progress during neoadjuvant chemotherapy (NCT). The aim of this study was to assess the value of Tumor infiltrating lymphocytes (TILs) in such a high-risk population where valid biomarkers are eagerly needed. A retrospective review identified BC patients who either progressed during NCT or achieved a pathologic complete response (pCR). An experienced BC pathologist semi-quantified stromal TILs in pre-treatment core biopsies using hematoxylin and eosin stained slides...

AIMS: Neoadjuvant chemotherapy (NAC) is often used to treat localized invasive breast cancer. Invasive mucinous carcinoma (IMC) is considered to be an indolent form of invasive breast cancer and is rarely treated with NAC. We report the largest series of IMC treated with NAC, and report a characteristic, but not well recognized, pattern of pathologic response. METHODS AND RESULTS: Our series included 7 patients with IMC treated with NAC. Three patients presented with locally advanced disease, three patients had tumors that were Her/2Neu positive, and four patients had tumors with admixed mucinous and micropapillary features...

Trastuzumab emtansine is an antibody-drug conjugate comprised of the anti-HER2 monoclonal antibody trastuzumab linked to DM1 (emtansine), a potent cytotoxic maytansinoid derivative, by a stable linker. This structure results in improved tumor-directed cytotoxicity in HER2+ breast cancer with reduced systemic toxicities, particularly the cardiac toxicities associated with single agent trastuzumab. Phase III trials have demonstrated improved progression-free and overall survival in heavily pretreated patients with advanced HER2+ breast cancer, with an acceptable toxicity profile...

BACKGROUND: Patient-derived xenografts (PDXs) are increasingly used in cancer research as a tool to inform cancer biology and drug response. Most available breast cancer PDXs have been generated in the metastatic setting. However, in the setting of operable breast cancer, PDX models both sensitive and resistant to chemotherapy are needed for drug development and prospective data are lacking regarding the clinical and molecular characteristics associated with PDX take rate in this setting...

Purpose of Review: Pre-operative endocrine therapy can be used to down-stage large or locally advanced breast cancers in ER+ disease. In the last four decades, it has evolved from a treatment perceived as an alternative to surgery for those too unfit to undergo surgery or chemotherapy, to the present day where it is a valuable and valid option in the treatment of postmenopausal women with ER-rich (Allred score 7-8, or > 50% staining for ER) breast cancer. Recent Findings: Emerging data from the metastatic setting is translating into neoadjuvant trials, utilising dual endocrine targeting or combinations of endocrine agents and other targeted drugs, including those acting against components of the PI3K pathway and the cell cycle...
