Abstract
BACKGROUND Up to 30% of metastatic breast cancer (BC) patients develop brain metastases (BM). Prognosis of patients with BM is poor and long-term survival is rare. Identification of factors associated with long-term survival is important for improving treatment modalities. PATIENTS AND METHODS A total of 2889 patients of the national registry for BM in BC (BMBC) were available for this analysis. Long-term survival was defined as overall survival (OS) in the upper third of the failure curve resulting in a cut-off of 15 months. A total of 887 patients were categorized as long-term survivors. RESULTS Long-term survivors compared to other patients were younger at BC and BM diagnosis (median 48 versus 54 years and 53 versus 59 years), more often had HER2-positive tumors (59.1% versus 36.3%), less frequently luminal-like (29.1% versus 35.7%) or triple-negative breast cancer (TNBC) (11.9% versus 28.1%), showed better Eastern Cooperative Oncology Group (ECOG) performance status (PS) at the time of BM diagnosis (ECOG 0-1, 76.9% versus 51.0%), higher pathological complete remission rates after neoadjuvant chemotherapy (21.6% versus 13.7%) and lower number of BM (n = 1, BM 40.9% versus 25.4%; n = 2-3, BM 26.5% versus 26.7%; n ≥4, BM 32.6% versus 47.9%) (P < 0.001). Long-term survivors had leptomeningeal metastases (10.4% versus 17.5%) and extracranial metastases (ECM, 73.6% versus 82.5%) less frequently, and asymptomatic BM more often at the time of BM diagnosis (26.5% versus 20.1%), (P < 0.001). Median OS in long-term survivors was about two times higher than the cut-off of 15 months: 30.9 months [interquartile range (IQR) 30.3] overall, 33.9 months (IQR 37.1) in HER2-positive, 26.9 months (IQR 22.0) in luminal-like and 26.5 months (IQR 18.2) in TNBC patients. CONCLUSIONS In our analysis, long-term survival of BC patients with BM was associated with better ECOG PS, younger age, HER2-positive subtype, lower number of BM and less extended visceral metastases. Patients with these clinical features might be more eligible for extended local brain and systemic treatment.

Abstract
Background Up to 40% of patients with metastatic human epidermal growth factor receptor 2 (HER2)-positive breast cancer develop brain metastases (BMs). Understanding of clinical features of these patients with HER2-positive breast cancer and BMs is vital. Patients and methods A total of 2948 patients from the Brain Metastases in Breast Cancer registry were available for this analysis, of whom 1311 had primary tumors with the HER2-positive subtype. Results Patients with HER2-positive breast cancer and BMs were—when compared with HER2-negative patients—slightly younger at the time of breast cancer and BM diagnosis, had a higher pathologic complete response rate after neoadjuvant chemotherapy and a higher tumor grade. Furthermore, extracranial metastases at the time of BM diagnosis were less common in HER2-positive patients, when compared with HER2-negative patients. HER2-positive patients had more often BMs in the posterior fossa, but less commonly leptomeningeal metastases. The median overall survival (OS) in all HER2-positive patients was 13.2 months (95% confidence interval 11.4-14.4). The following factors were associated with shorter OS (multivariate analysis): older age at BM diagnosis [≥60 versus <60 years: hazard ratio (HR) 1.63, P < 0.001], lower Eastern Cooperative Oncology Group status (2-4 versus 0-1: HR 1.59, P < 0.001), higher number of BMs (2-3 versus 1: HR 1.30, P = 0.082; ≥4 versus 1: HR 1.51, P = 0.004; global P = 0.015), BMs in the fossa anterior (HR 1.71, P < 0.001), leptomeningeal metastases (HR 1.63, P = 0.012), symptomatic BMs at diagnosis (HR 1.35, P = 0.033) and extracranial metastases at diagnosis of BMs (HR 1.43, P = 0.020). The application of targeted therapy after the BM diagnosis (HR 0.62, P < 0.001) was associated with longer OS. HER2-positive/hormone receptor-positive patients showed longer OS than HER2-positive/hormone receptor-negative patients (median 14.3 versus 10.9 months; HR 0.86, P = 0.03), but no differences in progression-free survival were seen between both groups. Conclusions We identified factors associated with the prognosis of HER2-positive patients with BMs. Further research is needed to understand the factors determining the longer survival of HER2-positive/hormone receptor-positive patients. Patients with HER2-positive BMs from breast cancer have the best prognosis compared with other tumor subtypes. Among HER2-positive patients, hormone receptor-positive patients have the longest survival. HER2-targeted therapy is significantly associated with a better prognosis in patients with BMs. On average, two HER2-targeted therapy lines were administered prior to the development of BMs. New compounds are urgently needed to improve the outcome of this subgroup of patients.

Abstract
Abstract
Introduction
Breast cancer diagnosed in young women who are 40 years (yrs) or younger is a relatively rare disease. However, it represents the most common cause of cancer-related deaths in this age-group. Furthermore, young age at diagnosis is associated with an increased risk of recurrence and worse survival. To date, general concepts concerning oncological cancer management should be driven by clinicopathological tumor characteristics and should adhere to standardized protocols for patients in general, but little is known about the oncological cancer treatment and outcome of this very young women in today's clinical practice.
Patients and Methods
The breast cancer in pregnancy registry study (BCP/GBG29/BIG 03-02) is a multicenter, international, observational study. BCP was established to investigate the oncological management and outcome of breast cancer in pregnancy. Since 2014 non-pregnant patients who are 40 yrs or younger are eligible if diagnosed with histological confirmed invasive breast cancer, independent of the type of treatment as control cohort. All patients received oncological treatment according to local standards. In this study the following endpoints will be analyzed descriptively for the young non-pregnant women cohort: breast cancer staging at diagnosis, biological characteristics of breast cancer at diagnosis, diagnostic procedures, treatment modalities, toxicity, pathological complete response after neoadjuvant chemotherapy, disease-free survival and overall survival.
Results
From February 2014 until June 2018, 969 non-pregnant patients ≤40 yrs have been registered. The median age at diagnosis was 35 yrs (range 19-40). Overall, 90.1% of patients had a stage T1-2 at diagnosis and 67.1% of patients had negative lymph nodes. 86.7% of tumors were invasive ductal carcinomas and 4.1% lobular carcinomas. Grading (G) 3 was reported in 55.5%. 26.6% of tumors were luminal A-like (ER- and/or PgR-positive, HER2-negative, G1-2), 40.0% luminal B-like (ER- and/or PgR-positive, HER2-negative, G3 or ER- and/or PgR-positive, HER2-positive, any G), 7.7% HER2 positive non-luminal-like, and 25.7% triple negative breast cancers. 3.8% of young non-pregnant patients had metastatic disease at primary diagnosis.
Conclusion
This registry comprises a large cohort of young non-pregnant patients with breast cancer diagnosed at the age of 40 yrs or younger and provides important data about a modern breast cancer treatment as well as oncological outcome in this setting of young women. Further results including oncological management, toxicity, and survival will be presented at the meeting.

Abstract
BACKGROUND Brain metastases (BMs) have a major impact on life expectancy and quality of life for many breast cancer patients. Knowledge about treatment patterns and outcomes is limited. METHODS We analysed clinical data of 1712 patients diagnosed with BMs from breast cancer between January 2000 and December 2016 at 80 institutions. RESULTS Median age at diagnosis of BMs was 56 years (22-90 years). About 47.8% (n = 732) of patients had HER2-positive, 21.4% (n = 328) had triple-negative and 30.8% (n = 471) had hormone receptor (HR)-positive, HER2-negative (luminal-like) primary tumours. The proportion of patients with HER2-positive BMs decreased comparing the years 2000-2009 with 2010-2015 (51%-44%), whereas the percentage of patients with luminal-like tumours increased (28%-34%; p = 0.0331). Patients with BMs in the posterior fossa were more often HER2 positive (n = 169/314, 53.8%) than those diagnosed with triple-negative (n = 65/314, 20.7%) or luminal-like primary breast cancer (n = 80/314, 25.5%), (p < 0.0001). Median overall survival (OS) time after development of BMs for the overall cohort was 7.4 months (95% confidence interval [CI]: 6.7-8.0 months). One-year survival rate was 37.7% (95% CI: 35.2-40.1). Patients with HER2-positive tumours had the longest median OS of 11.6 months (95% CI: 10.0-13.4) compared with 5.9 months (95% CI: 5.0-7.2) for patients with luminal-like and 4.6 months (95% CI: 3.9-5.4) for patients with triple-negative tumours. Patients with HER2-positive tumours who received anti-HER2 treatment had longer median OS than those without (17.1 months versus 7.2 months, p < 0.0001). CONCLUSIONS Prognosis of patients after developing BMs varies significantly according to the subtype. The outcome in this cohort is similarly poor in triple-negative and HR-positive/HER2-negative patients. Our results underline the high medical need for improvement of treatment and prevention strategies for BMs in breast cancer patients.

Abstract
Abstract
Background:Currently, breast cancer during pregnancy (BCP) is not believed to be biologically different from breast cancer unrelated to pregnancy based on limited datasets mainly obtained by immunohistochemistry. However, some groups report that BCP patients have an inferior survival compared to young non-pregnant breast cancer patients. The largest analysis based on the BCP registry by the German Breast Group (GBG) revealed however, no difference between pregnant and non-pregnant breast cancer patients, indicating that treatment rather than biology might be the reason for the inferior survival reported by others.
Methods: The BCP study (GBG 29/BIG 03-02) is a multicentre observational study for breast cancer during pregnancy. In tumour tissue collected within this study from pregnant M0 patients we investigated the following genes: AKT1, ATM, BRAF, CBFB, CCND1, CDH1, CDKN2A, CTCF, EGFR, ERBB2, ESR1, FGFR2, GATA3, KRAS, MAP2K4, MAP3K1, MDM2, MED12, MYC, PIK3CA, PIK3R1, PTEN, RB1, RUNX1, and TP53 by massive parallel sequencing (MPS). This included patients with all molecular subtypes: HR+/-, HER2+/-. Sequencing was done on an IonTorrent Proton using a custom designed Breast Cancer Panel (BCPv2). This panel comprises 236 amplicons split into two primer pools and covers hotspot regions of 138 exons of the 25 genes.
To test the hypothesis that breast cancer diagnosed during pregnancy is biologically not different from breast cancer diagnosed in young non-pregnant women, we compared the molecular profiles obtained, with genetic data from M0 patients not known to be pregnant from TCGA with age <= 45. TCGA data were pre-processed to be compatible to the targeted MPS datasets from pregnant patient.
Results: Material from 141 patients from the BCP study was available from which ultimately 109 fully evaluable MPS datasets could be obtained. In the TCGA data set 114 breast cancer patients <= 45 years could be identified. Pregnant patients with breast cancer were significantly younger, had more often HR- tumours (59.6% vs 30.1%) but had less frequently grade 3 tumours (30.6% vs 48.2%). All other clinical variables showed no significant differences between pregnant and non-pregnant patients. In the BCP data, overall 106 mutations could be found. The most frequent mutations were detected in TP53 (62%) and in PIK3CA (11.1%). In non-pregnant patients the mutation rates were different with 32.5% in TP53 and 21.1% in PIK3CA.
Exact matching by variables age, HR, HER2 and grade yielded 40 patients from both datasets. In these subcohorts, still divergent mutational rates for TP53 and PIK3CA between pregnant and non-pregnant women were noted, however, the differences failed to reach statistical significance.
Conclusions: Overall the mutational landscapes do not seem to be overtly different between pregnant patients and no-pregnant controls, although slight imbalances in mutational rates occurred, which might be partly explained by a selection bias and a small sample size after matching. Further comparisons using other datasets, looking into survival and regarding copy number variation are currently conducted.

Abstract
Abstract
Background: The incidence of brain metastases (BM) in breast cancer patients is rising and has become a major clinical challenge. So far, limited therapeutic options and insights into the biology of BM exist since only a few studies analyzed exclusively data of breast cancer patients. In order to improve this situation, our multicenter registry was initiated in 2014: Brain Metastases in Breast Cancer Network Germany (BMBC, GBG79).
Materials and Methods: Patients with BM diagnosed since 2000, a history of breast cancer and no history of other malignant or neurologic disease can be included. Registration is allowed retrospectively as well as prospectively into a web–based database ("MedCodes"). Characteristics of the primary tumor, metastatic disease and BM as well as treatment details are documented. For this first analysis, 548 patients from 39 German centers were included.
Results: Median age at first diagnosis of BM was 55 years (25 – 90 years). 43% of patients (233/548) were HER2 positive, 19% (n=105) were triple–negative and 25% (n= 138) had luminal primary tumors indicating a selection of patients with specific tumor biology who develop BM. 54 % of the patients (n=267) had up to three BM whereas 45% (n=223) had more than three BM. 19% of patients (n=106) had BM without evidence of extracranial disease. 27% of the patients (n=146) underwent surgery of the BM. Of these patients, 61% (n= 89) were treated with whole brain radiotherapy and 16% (n=23) with stereotactic radiotherapy. In patients without surgery (n=397), 73% (n=289) received whole brain radiotherapy and 7% (n=28) stereotactic radiotherapy.
Median time from diagnosis of primary breast cancer to BM was 38.5 month for the entire cohort (CI95% 35.4 – 43.3). The time from first diagnosis to BM was shorter for triple–negative patients (20.9 month, CI95% 15.5 – 25.9) compared with patients with HER2–positive (37.0 month, CI95% 30.5 – 42.0) or luminal tumors (48.3 month, CI95% 38.2 – 54.0) (p<0.001). Median time from first diagnosis of BM to death in the entire cohort was 6.1 months (CI95%: 5.2 – 7.3). One year survival rate from diagnosis of BM was 32.2 % (CI95%: 2.2 – 67.8). Regarding tumor subtypes, HER2–positive patients had the longest median survival with 9.4 months (CI95%: 7.1 – 13.4) compared with 6 months (CI95%: 4.0 – 7.3) for luminal primary tumors and 3.2 months (CI95%: 2.1 – 4.6) for triple–negative patients (p<0.001). HER2 positive patients receiving HER2–directed therapy after the diagnosis of BM lived longer than those without (median 9.6 vs. 5.5 months, p=0.029). Regarding the number of BM, no difference in survival was observed between one, two or three BM (median survival of 7.8 months). However, survival was shorter in those patients with more than three BM (5.2 months; p=0.007).
Conclusion: This is so far the largest analysis of breast cancer patients with BM treated in Germany. In this cohort, triple–negative subtype or more than three BM were associated with shorter survival from the diagnosis of BM. HER2 positive patients with no HER2 directed therapy after the diagnosis of BM showed a shorter survival. The recruitment of the registry is ongoing and we aim to include more than 1000 patients by the end of 2015.

Abstract
We present the results of a search for point sources of high-energy neutrinos in the northern hemisphere using AMANDA-II data collected in the year 2000. Included are flux limits on several active-galactic-nuclei blazars, microquasars, magnetars, and other candidate neutrino sources. A search for excesses above a random background of cosmic-ray-induced atmospheric neutrinos and misreconstructed downgoing cosmic-ray muons reveals no statistically significant neutrino point sources. We show that AMANDA-II has achieved the sensitivity required to probe known TeV gamma-ray sources such as the blazar Markarian 501 in its 1997 flaring state at a level where neutrino and gamma-ray fluxes are equal.

Abstract
Data from the AMANDA-B10 detector taken during the austral winter of 1997 have been searched for a diffuse flux of high energy extraterrestrial muon neutrinos. This search yielded no excess events above those expected from background atmospheric neutrinos, leading to upper limits on the extraterrestrial neutrino flux measured at the earth. For an assumed E-2 spectrum, a 90% classical confidence level upper limit has been placed at a level E2Phi(E)=8.4 x 10(-7) cm(-2) s(-1) sr(-1) GeV (for a predominant neutrino energy range 6-1000 TeV), which is the most restrictive bound placed by any neutrino detector. Some specific predicted model spectra are excluded. Interpreting these limits in terms of the flux from a cosmological distributions of sources requires the incorporation of neutrino oscillations, typically weakening the limits by a factor of 2.

Abstract
Neutrinos are elementary particles that carry no electric charge and have little mass. As they interact only weakly with other particles, they can penetrate enormous amounts of matter, and therefore have the potential to directly convey astrophysical information from the edge of the Universe and from deep inside the most cataclysmic high-energy regions. The neutrino's great penetrating power, however, also makes this particle difficult to detect. Underground detectors have observed low-energy neutrinos from the Sun and a nearby supernova, as well as neutrinos generated in the Earth's atmosphere. But the very low fluxes of high-energy neutrinos from cosmic sources can be observed only by much larger, expandable detectors in, for example, deep water or ice. Here we report the detection of upwardly propagating atmospheric neutrinos by the ice-based Antarctic muon and neutrino detector array (AMANDA). These results establish a technology with which to build a kilometre-scale neutrino observatory necessary for astrophysical observations.
