Abstract
BACKGROUND The GeparQuinto study showed that adding bevacizumab to 24 weeks of anthracycline-taxane-based neoadjuvant chemotherapy increases pathological complete response (pCR) rates overall and specifically in patients with triple-negative breast cancer (TNBC). No difference in pCR rate was observed for adding everolimus to paclitaxel in nonearly responding patients. Here, we present disease-free (DFS) and overall survival (OS) analyses. PATIENTS AND METHODS Patients (n = 1948) with HER2-negative tumors of a median tumor size of 4 cm were randomly assigned to neoadjuvant treatment with epirubicin/cyclophosphamide followed by docetaxel (EC-T) with or without eight infusions of bevacizumab every 3 weeks before surgery. Patients without clinical response to EC ± Bevacizumab were randomized to 12 weekly cycles paclitaxel with or without everolimus 5 mg/day. To detect a hazard ratio (HR) of 0.75 (α = 0.05, β = 0.8) 379 events had to be observed in the bevacizumab arms. RESULTS With a median follow-up of 3.8 years, 3-year DFS was 80.8% and 3-year OS was 89.7%. Outcome was not different for patients receiving bevacizumab (HR 1.03; P = 0.784 for DFS and HR 0.974; P = 0.842 for OS) compared with patients receiving chemotherapy alone. Patients with TNBC similarly showed no improvement in DFS (HR = 0.99; P = 0.941) and OS (HR = 1.02; P = 0.891) when treated with bevacizumab. No other predefined subgroup (HR+/HER2-; locally advanced (cT4 or cN3) or not; cT1-3 or cT4; pCR or not) showed a significant benefit. No difference in DFS (HR 0.997; P = 0.987) and OS (HR 1.11; P = 0.658) was observed for nonearly responding patients receiving paclitaxel with or without everolimus overall as well as in subgroups. CONCLUSIONS Long-term results, in opposite to the results of pCR, do not support the neoadjuvant use of bevacizumab in addition to an anthracycline-taxane-based chemotherapy or everolimus in addition to paclitaxel for nonearly responding patients.

Abstract
Analysis of 4,405 variants in 89,050 European subjects from 41 case-control studies identified three independent association signals for estrogen-receptor-positive tumors at 11q13. The strongest signal maps to a transcriptional enhancer element in which the G allele of the best candidate causative variant rs554219 increases risk of breast cancer, reduces both binding of ELK4 transcription factor and luciferase activity in reporter assays, and may be associated with low cyclin D1 protein levels in tumors. Another candidate variant, rs78540526, lies in the same enhancer element. Risk association signal 2, rs75915166, creates a GATA3 binding site within a silencer element. Chromatin conformation studies demonstrate that these enhancer and silencer elements interact with each other and with their likely target gene, CCND1.

Abstract
Abstract
Background: Secreted protein acidic and rich in cysteine (SPARC) is an albumin-binding protein and associated with poor prognosis in multiple cancers.
The aim of this analysis was to determine the frequency of SPARC expression among different molecular breast cancer subtypes and to evaluate its predictive value for therapy response after neoadjuvant anthracycline/taxane based chemotherapy (CTX) in participants of the GeparTrio trial.
Methods: We evaluated tumoral SPARC expression by immunohistochemistry on tissue microarrays (TMAs) constructed from formalin-fixed paraffin-embedded (FFPE) pre-treatment core biopsies from 667 patients (pts) of the GeparTrio trial. The details of the GeparTrio study design are described elsewhere (von Minckwitz, JNCI 2008). Cutoffs for SPARC expression were determined using the web-based software Cutoff Finder (http://molpath.charite.de/cutoff/).
Results: SPARC protein expression was measurable by IHC on the TMAs and 176 (26.4 %) of 667 tumors were SPARC positive. SPARC expression was increased in pts with triple-negative breast cancer (TNBC) compared to hormone receptor or HER2 positive subtypes (p = 0.039).
SPARC positivity was associated with an increased pCR rate in the overall population (p < 0.001). SPARC negative tumors had a pCR rate of 15%, which increased to 27% in SPARC positive tumors. Similarly, in TNBC the pCR rate increased from 26% in SPARC negative tumors to 47% in SPARC positive tumors (p = 0.032).
In multivariate logistic regression analysis adjusted for standard clinicopathological factors, SPARC was independently predictive in the overall population (p = 0.010) as well as the subgroups of pts with TNBC (p = 0.036).
Conclusions: SPARC is expressed in all biological breast cancer subtypes with TNBC revealing the highest expression rate. Our data suggest that SPARC expression may provide predictive information for response to neoadjuvant CTX.
As SPARC is an albumin-binding protein and might mediate intratumoral accumulation of nab-Paclitaxel, prospective analysis of SPARC expression is planned in the GeparSepto trial.

Abstract
PURPOSE Elastography is a new ultrasonographic method that has been examined as a diagnostic tool for breast lesions. This study was intended to create and define new elastographic criteria allowing assessment of whether breast lesions are malignant or benign. MATERIALS AND METHODS 217 patients with a total of 245 breast lesions of unknown malignancy underwent ultrasound examination. The new eSie Touch Elasticity Imaging technology (Siemens, Erlangen, Germany) was used with a 10-MHz linear transducer (Acuson Antares). Lesions were examined using B-mode and real-time elastography (RTE). Each lesion was histologically assessed by core biopsy. Five RTE characteristics were examined: elasticity proportion (EP), different location on RTE in comparison with B-mode (MV), different contrast patterns (SOS), dorsal lesion limitation visibility and different size on RTE in comparison with B-mode. RESULTS 54 malignant lesions (54 %) appeared inelastic, in contrast to the benign control group (34.5 %; P = 0.001). A completely elastic pattern was visible in 10 malignant (10 %) and 39 benign lesions (26.9 %). MV was identified in 23 cases, with 22 of the lesions being malignant and one benign. The SOS was negative in 89 malignant lesions (89 %) and positive in 100 benign lesions. The dorsal lesion limitation was visible on RTE without B-mode in 88 malignant lesions (88 %) and 27 benign lesions (18.6 %). The size was assessed as larger in 45 malignant lesions (45 %) and seven benign lesions (4.8 %). CONCLUSION SOS and a larger tumor size on RTE are specific characteristics of malignant breast lesions. EP, MV and distal mass border are further helpful signs to assess the malignancy of tumors.

Abstract
Abstract
Background: Assessment of HER2 status at the time of metastatic disease might help to optimize treatment decisions in patients with no HER2 status determined at first diagnosis and could also be helpful since HER2 status may change during disease progression. In this context, determination of serum HER2 or the evaluation of HER2 status on circulating tumor cells (CTC) is of potential relevance especially for optimizing HER2-directed therapy. The aim of this study was therefore to determine the serum HER2 status and the HER2 status of CTC from corresponding patients.Methods: Blood samples were obtained in a prospective multicenter setting from 251 patients with metastatic breast cancer at the time of disease progression. Serum HER2 was determined using the commercial HER2 ELISA-kit (Oncogene Science). CTC were detected and HER2 expression was assessed with the CellSearch™ system (Veridex).Results: 119 of 251 (47%) metastatic patients had elevated serum HER2 levels above 15 ng/mL. Serum HER2 was elevated in 49 (66%) of 74 patients with HER2 positive primary tumors, in 57 of 148 (39%) with HER2 negative primary tumors and in 13 of 29 (45%) patients with unknown HER2 primary tumor status. CTC were detected in 133 of 243 evaluable patients (5 or more cells), in these HER2 overexpression on CTC (strong overexpression in at least one cell) was detected in 52 cases (39%). Only 20 of these patients had a HER2 positive primary tumor. In patients with HER2 positive CTC, serum levels were above the cut off in 34 of 52 (65%), while in those with HER2 negative CTC 44 of 81 (54%) showed elevated HER2 serum levels. Concordance between HER2 status of circulating tumor cells and elevated serum HER2 was seen in 71 of 133 patients (53%).Conclusions: Our study demonstrates with a prospective design that also in patients with initially negative HER2 tumor status elevated serum HER2 levels and/or HER2 positive CTC can be detected at the time of metastatic disease. This is of clinical relevance since these patients in current practice do not have access to HER2 targeted therapy.
