Abstract
Background Patients' compliance and persistence with endocrine treatment has a significant effect on the prognosis in early breast cancer (EBC). The purpose of this analysis was to identify possible reasons for non-persistence, defined as premature cessation of therapy, on the basis of patient and tumor characteristics in individuals receiving adjuvant treatment with letrozole. Patients and methods The EvAluate-TM study is a prospective, multicenter, noninterventional study in which treatment with the aromatase inhibitor letrozole was evaluated in postmenopausal women with hormone receptor-positive EBC in the early therapy phase. Treatment persistence was evaluated at two pre-specified study visits after 6 and 12 months. As a measure of early therapy persistence the time from the start to the end of treatment (TTEOT) was analyzed. Cox regression analyses were carried out to identify patient characteristics and tumor characteristics predicting TTEOT. Results Out of the total population of 3941 patients with EBC, 540 (13.7%) events involving treatment cessation unrelated to disease progression were observed. This was due to drug-related toxicity in the majority of cases (73.5%). Persistence rates were 92.2%, 86.9%, and 86.3% after 6, 12, and 15 months, respectively. The main factors influencing premature treatment discontinuation were older age [hazard ratio (HR) 1.02/year], comorbidities (HR 1.06 per comorbidity), low body mass index, and lower tumor grade (HR 0.85 per grade unit). Conclusion These results support the view that older, multimorbid patients with low tumor grade and low body mass index are at the greatest risk for treatment discontinuation and might benefit from compliance and support programs.

Abstract
We analyzed the predictive potential of pretreatment soluble carbonic anhydrase IX levels (sCAIX) for the efficacy of bevacizumab in the phase III neoadjuvant GeparQuinto trial. sCAIX was determined by enzyme-linked immunosorbent assay (ELISA). Correlations between sCAIX and pathological complete response (pCR), disease-free and overall survival (DFS, OS) were assessed with logistic and Cox proportional hazard regression models using bootstrapping for robust estimates and internal validation. 1,160 HER2-negative patient sera were analyzed, of whom 577 received bevacizumab. Patients with low pretreatment sCAIX had decreased pCR rates (12.1 vs. 20.1%, p = 0.012) and poorer DFS (adjusted 5-year DFS 71.4 vs. 80.5 months, p = 0.010) compared to patients with high sCAIX when treated with neoadjuvant chemotherapy (NCT). For patients with low sCAIX, pCR rates significantly improved upon addition of bevacizumab to NCT (12.1 vs. 20.4%; p = 0.017), which was not the case in patients with high sCAIX (20.1% for NCT vs. 17.0% for NCT-B, p = 0.913). When analyzing DFS we found that bevacizumab improved 5-year DFS for patients with low sCAIX numerically but not significantly (71.4 vs. 78.5 months; log rank 0.234). In contrast, addition of bevacizumab worsened 5-year DFS for patients with high sCAIX (81 vs. 73.6 months, log-rank 0.025). By assessing sCAIX levels we identified a patient cohort in breast cancer that is potentially undertreated with NCT alone. Bevacizumab improved pCR rates in this group, suggesting sCAIX is a predictive biomarker for bevacizumab with regards to treatment response. Our data also show that bevacizumab is not beneficial in patients with high sCAIX.

Abstract
Abstract
Background:
Recent trials have provided evidence that obesity and a low level of physical activity are not only associated with a higher risk of developing breast cancer, but also with an increased risk for recurrence and reduced survival in breast cancer patients (pts). The SUCCESS C study is the first randomized Phase III trial to evaluate the effect of an intensive lifestyle intervention program, focusing on both physical activity and healthy diet following adjuvant chemotherapy on disease-free survival in women with early breast cancer.
Methods:
SUCCESS C is a German multicenter, 2×2 factorial design, randomized phase III study comparing disease-free survival (DFS) in pts with HER2-negative early breast cancer treated with either 3 cycles of epirubicine, fluorouracil, cyclophosphamide chemotherapy followed by 3 cycles of docetaxel (FEC-D) or 6 cycles of docetaxel-cyclophosphamide (DC). The second randomization compares DFS in pts with a body mass index (BMI) of 24—40 kg/m2 receiving either a telephone-based individualized lifestyle intervention (LI) program aiming at moderate weight loss for 2 years (LI arm) or general recommendations for a healthy lifestyle alone (non-LI arm). DFS according to lifestyle intervention was analyzed using both univariable cox regressions and multivariable cox regressions adjusted for age (years, continuous), BMI (kg/m2, continuous), menopausal status (premenopausal, postmenopausal), tumor size (pT1, pT2, pT3/pT4), nodal stage (pN0, pN1, pN2, pN3), hormone receptor status (positive, negative), grading (G1, G2, G3), histological type (ductal, lobular, other) and chemotherapy randomization (FEC-D, DC). Median follow-up was 64.2 months.
Results:
Overall, 2292 of the 3643 pts recruited for the SUCCESS C study were randomized for the lifestyle intervention program (1146 pts in both the non-LI arm and the LI arm). The Intention-to-treat analysis revealed no difference in DFS between the two treatment arms (LI vs. non-LI) in univariable analysis (hazard ratio [HR] 0.99, 95% confidence interval [CI] 0.76 — 1.28, p = 0.922) and in adjusted multivariable cox regression (HR 0.91, 95% CI 0.70 — 1.18, p = 0.48). At the 2-year follow up, pts in the LI arm lost on average 1.0 kg weight compared to the start of the LI program, while pts in the non-LI arm gained on average 0.95 kg (p < 0.001). Overall, 1477 pts completed the 2-year LI program (non-LI arm: 80.7%, 925 of 1146 pts; LI arm: 48.2%, 552 of 1146 pts; p < 0.001). Pts that completed the 2-year LI program had a significant better DFS than non-completers (HR 0.35, 95% CI 0.27 — 0.45, p < 0.001). Among completers, pts in the LI arm had a significantly better DFS than pts in the non-LI arm both in univariable analysis (HR 0.53, 95% CI 0.35 — 0.82, p = 0.004) and in adjusted multivariable cox regression (HR 0.51, 95% CI 0.33 — 0.78, p = 0.002).
Conclusions:
This explorative and non-planned interim analysis indicates that the completion of a systematic telephone life style intervention program may positively impact patient outcome in early breast cancer.

Abstract
Abstract
Background:
Currently, patients with breast cancer (BC) with hormone receptor (HR) immunohistochemical expression between 1-9% are eligible to receive endocrine therapy. However, recent data suggest that these tumors express a basal-like molecular phenotype associated with triple negative BC (TNBC) rather than luminal phenotype associated with HR positive BC. Here, we aimed to determine the differences between strong HR positive, low HR positive and negative HR BC, in regard to responsiveness to neoadjuvant chemotherapy (NACT) and disease free survival (DFS) in large cohorts from GBG clinical trials.
Methods:
In this retrospective analysis of data from women with BC treated in the neoadjuvant GeparQuinto (n=2572), GeparSixto (n=588) and GeparSepto (n=1206) clinical trials, we compared patients with three HR phenotypes: low positive (ER and/or PR= 1-9%), strong positive (ER or PR= 10-100%), and negative (ER and PR= <1%), regarding pathological complete response (pCR, ypT0 ypN0) and DFS. A logistic regression model for endpoint pCR was performed on pooled data from all trials. Cox regression was used to model DFS for patients participating in GeparQuinto and GeparSixto trial, including 71 with low HR positive phenotype. The models were adjusted by age, tumor and nodal status, grading, Her2 status, histological type, stromal and tumor infiltrating lymphocytes and clinical trial. The survival model was additionally adjusted by pCR after NACT.
Results:
Patients median age was 49 years, the majority had clinical tumor stage 2 (54.1%), negative nodal status (54.7%), and Her2 negative tumors (72.4%). 85.1% of women had BC classified as no special histological type. The pCR rate across the studies was 26.2%. 145 (3.4%) patients had low HR positive, 2417 (57.3%) strong HR positive and 1658 (39.3%) HR negative tumors. After NACT, 16.3% of patients with strong HR positive BC achieved a pCR, while among those with HR negative and low HR positive tumors, pCR rates were 40.2% and 37.9%, respectively (p<0.001). In the adjusted logistic regression model, there was no statistically significant difference between low HR positive and HR negative tumors (OR: 1.34, 95%-CI: (0.84-2.13), p=0.222). But strong HR positive tumors had a significantly lower chance of achieving a pCR compared to low HR positives (OR 0.48, 95%-CI: 0.30-0.76, p=0.002). Patients with strong HR positive BC had a better DFS than patients with low HR positive tumors (hazard ratio 0.35, 95%-CI: 0.18-0.70, p=0.003). DFS was not significantly different between patients with HR negative and low HR positive tumors (hazard ratio 0.74, 95%-CI: 0.38-1.43, p=0.370).
Conclusions:
Similarly to patients with negative HR tumors, patients with low HR positive tumors have a better responsiveness to NACT and worse survival rates, compared to patients with strongly HR positive BC. We suggest that studies on treatment options for basal-like/TNBC, should also consider including patients with low HR positive tumors.

Abstract
Abstract
Background
Even though patients with a pCR following neoadjuvant chemotherapy have an excellent prognosis still some of these patients will eventually relapse. A better identification of pts with an increased risk of relapse despite a pCR would be helpful to select these patients for additional post-neoadjuvant treatment strategies. Thus, the rationale of this retrospective analysis was to identify factors predicting relapse despite a pCR.
Methods
This pooled retrospective analysis based on the GBG meta-database includes the neoadjuvant trials GeparTrio, GeparQuattro, GeparQuinto, GeparSixto and GeparSepto. In these trials 2188 (27%) of 7933 pts had a pCR according to ypT0/ypTis ypN0 Definition and were included. The primary endpoint was disease-free survival (DFS), secondary endpoints were distant DFS (DDFS) and overall survival (OS). A multivariate Cox proportional hazards model was used to report hazard ratios with 95% confidence interval (CI). The two-sided significance level was set to α=0.05. Endpoints were analysed for all pts and in subgroups defined by intrinsic subtypes. The potential risk factors intrinsic subtype (HER2 negative/hormone receptor (HR) positive, triple negative, HER2 positive/HR positive, HER2 positive/HR negative), histological tumor type (lobular vs other), grade (G1/G2 vs G3), KI67 (≤20% vs higher), initial cT and cN stadium (cT1 vs cT2 vs cT3/4; cN0 vs cN+), age (≤40 vs 41-59 vs ≥60), BMI (< 25 vs 25-29 vs ≥ 30), planned number of cycles of chemotherapy (≤6 vs > 6), menopausal status (pre- vs postmenopausal) and clinical response after 2-4 cycles (SD vs PR vs CR vs PD) were included as covariates in multivariate Cox regression models as well as study identification.
Results
From 2188 evaluable patients DFS, DDFS and OS events were observed in 290/197/130 pts respectively; the median follow-up over all studies was 59 months. In multivariate analysis including study and all potential risk factors DFS was significantly different with regard to the initial cN status (cN+ vs cN0, hazard ratio (HR) 1.70; 95% CI [1.2, 2.4], p=0.002). Of borderline significance was histological type (non-lobular vs lobular, HR 0.52 95% CI [0.3, 1.1]; p=0.076) and initial tumor stage (cT3/4 vs cT1, HR 1.61 95% CI [1.0, 2.7]; p=0.064). In terms of DDFS significant differences were seen for the initial cN status (cN+ vs cN0, HR 2.34; 95% CI [1.5, 3.6], p<0.001) and initial tumor stage (cT3/4 vs cT1, HR 1.83 95% CI [1.0, 3.3]; p=0.044); histological type was again close to significance (non-lobular vs lobular, HR 0.46 95% CI [0.2, 1.1]; p=0.067). Multivariate analysis showed significantly worse OS with initial cT3/4 tumors (cT3/4 vs cT1, HR 2.48 95%CI [1.1, 5.7]; p=0.030), and the lobular type (non-lobular vs lobular, HR 0.35 95% CI [0.1, 0.9]; p=0.026) and a trend for worse OS in pts with cN+ (cN+ vs cN0, HR 1.67 95% CI [1.0, 2.9]; p=0.067).
Conclusions
Initial tumor load before start of neoadjuvant chemotherapy (tumor stage and nodal status) and lobular subtype were predictors of long term outcome after a pCR following neoadjuvant chemotherapy. Intrinsic subtype, KI67, grade and planned number of cycles were not predictive for a relapse.

Abstract
Objective Routine serial hematocrit measurements are a component of the trauma evaluation for patients without serious injury identified on initial evaluation. We sought to determine whether serial hematocrit testing was useful in predicting the probable injuries in blunt abdominal trauma. Materials and method We performed a prospective study of trauma patients admitted in our observation unit over a 12-month period. Patients routinely underwent serial hematocrit testing in 6-hour intervals (two hematocrit levels). We compared trauma patients with a hematocrit drop of 5 and 10 points or more to those without a significant hematocrit drop. Results Five hundred forty-two isolated blunt abdominal trauma patients were admitted to observation unit, and 468 patients (86.35%) had serial hematocrit during their 6-hour stay. Of these patients, 36.11% had a hematocrit drop of 5 or more and 12.61% a drop of 10 or more. Of patients with the hematocrit drop >10, 50.8% have had diagnostic manifestations of intra-abdominal injury in both ultrasonographic and computed tomography scanning (P<0.001). There was no significant correlation between hematocrit drop >5 and positive imaging. Conclusion Although serial hematocrit testing may be useful in specific situations, routine use of serial hematocrit testing in trauma patients at a level I trauma center’s observation unit did not significantly aid in the prediction of occult injuries.

Abstract
INTRODUCTION Painful surgical procedures require adequate sedation and analgesia. A vast array of medications can be used for Procedural Sedation and Analgesia (PSA) in Emergency Departments (EDs). OBJECTIVE The present study was conducted to compare Propofol-Ketamine (PK) and Propofol-Fentanyl (PF) compounds in patients undergoing closed reduction in EDs. METHODS This randomized, double-blind, clinical trial was conducted on 110 consecutive patients who required sedation for closed reduction. The patients were randomly divided into two groups of equal sizes. The PK group received an intravenous bolus of 1 mg/kg of propofol plus 0.5 mg/kg of ketamine, and the PF group received an intravenous bolus of 1 mg/kg of propofol plus 1 µg/kg of fentanyl. The analgesic effect and success rate were the primary outcomes under study. RESULTS The PK group achieved more effective analgesia at the end of the experiment. The success rate was almost the same in both groups Shivering (p=0.005) and a drop in oxygen saturation to below 92% (p=0.048) were two side effects that were more prevalent in the FK group. The mean recovery time was significantly shorter in the PK group (p<0.001). The patients in the PK group were more satisfied. CONCLUSION In comparison with the PF compound, the use of KP leads to better pain relief and greater patient satisfaction and shorter sedation time in PSA.

Abstract
Purpose BRCA1/2 mutations are frequent in patients with triple-negative breast cancer (TNBC). These patients are often treated with primary systemic chemotherapy. The aim of this study was to analyze the effects of BRCA1/2 mutations on pathologic complete response (pCR) and disease-free survival (DFS) in a cohort of patients with TNBC treated with anthracycline and taxane-containing chemotherapy, with or without bevacizumab. Patients and Methods Germline DNA was sequenced to identify mutations in BRCA1 and BRCA2 in 493 patients with TNBC from the GeparQuinto study. The pCR rates were compared in patients with and without mutation, as well as in patients treated with and without bevacizumab. In addition, the influence of BRCA1/2 mutation status and pCR status on DFS was evaluated relative to treatment. Results BRCA1/2 mutations were detected in 18.3% of patients with TNBC. Overall, patients with mutations had a pCR rate of 50%, compared with 31.5% in patients without a mutation (odds ratio [OR], 2.17; 95% CI, 1.37 to 3.46; P = .001). The pCR rate among patients treated with bevacizumab was 61.5% for BRCA1/2 mutation carriers and 35.6% for those without mutations (OR, 2.90; 95% CI, 1.43 to 5.89; P = .004). pCR was a strong predictor of DFS for patients without BRCA1/2 mutations (hazard ratio, 0.18; 95% CI, 0.11 to 0.31) but not for patients with BRCA1/2 mutations (hazard ratio, 0.74; 95% CI, 0.32 to 1.69). Conclusion The addition of bevacizumab may increase the pCR after standard neoadjuvant chemotherapy for patients with TNBC with BRCA1/2 mutations. In patients treated with anthracycline and taxane-based chemotherapy (with or without bevacizumab), pCR was a weaker predictor of DFS for BRCA1/2 mutation carriers than for patients without mutations.

Abstract
Purpose The GeparQuinto phase III trial demonstrated a lower pathologic complete response (pCR; pT0 ypN0) rate when lapatinib was added to standard anthracycline–taxane chemotherapy compared with trastuzumab in patients with human epidermal growth factor receptor 2 (HER2) –positive breast cancer. Here, we report the long-term outcomes. Methods Patients with HER2-positive tumors (n = 615) received neoadjuvant treatment with epirubicin (E) plus cyclophosphamide (C), followed by docetaxel (T) in combination with either lapatinib (L) or trastuzumab (H; ECH-TH arm: n = 307; ECL-TL arm: n = 308). All patients received adjuvant trastuzumab for a total of 12 months and 18 months in the ECH-TH and ECL-TL arms, respectively. Median follow-up was 55 months. Results Three-year disease-free survival (DFS), distant DFS (DDFS), and overall survival (OS) were not significantly different between the two treatment arms. Long-term outcomes correlated with pCR (DFS: hazard ratio [HR], 0.63; P = .042; DDFS: HR, 0.55; P = .021; and OS: HR, 0.31; P = .004). A benefit only for OS was observed in patients who were treated with trastuzumab and achieved pCR versus no pCR (HR, 0.15; P = .010), whereas no difference was found in patients with pCR versus without pCR in the lapatinib arm. DFS and DDFS remained unchanged in both treatment arms according to hormone receptor status, whereas OS was significantly better in hormone receptor–positive patients who were treated with neoadjuvant lapatinib (HR, 0.32; P = .019), followed by adjuvant trastuzumab. No difference was observed in hormone receptor–negative patients; however, the small number of events limits this interpretation. Within the hormone receptor–negative cohort, pCR was significantly associated with DFS, DDFS, and OS ( P = .002, .005, and .002, respectively). Conclusion pCR correlated with long-term outcome. In patients with hormone receptor–positive tumors, prolonged anti-HER2 treatment—neoadjuvant lapatinib for 6 months, followed by adjuvant trastuzumab for 12 months—significantly improved survival compared with anti-HER2 treatment with trastuzumab alone.

Abstract
BACKGROUND Endocrine treatment (ET) with an aromatase inhibitor (AI) is the treatment of choice in post-menopausal patients with hormone receptor-positive early breast cancer (EBC). However, adverse events (AEs) often lead to treatment discontinuation. This analysis aimed to identify side-effects that lead to patients failing to persist with letrozole treatment. PATIENTS AND METHODS Post-menopausal hormone receptor-positive EBC patients starting ET with letrozole were enroled in EvAluate-TM, a non-interventional study. Information regarding treatment compliance and persistence was gathered in months 6 and 12. Persistence was defined as the time from 30 d after the start to the end of treatment. The influence on persistence of musculoskeletal syndrome, menopausal disorder, sleep disorder and other AEs within the first 30 d was analysed using Cox regression analyses. RESULTS Among 3887 patients analysed, the persistence rate after 12 months was >85%. In all, 568 patients (14.6%) discontinued the treatment, 358 of whom (63.0%) did so only because of side-effects. The main AEs influencing persistence were musculoskeletal symptoms (hazard ratio [HR] 2.55; 95% confidence interval [CI], 1.90-3.42), sleep disorders (HR 1.95; 95% CI, 1.41-2.70) and other AEs (HR 2.03; 95% CI, 1.51-2.73). Menopausal disorder was not associated with non-persistence (HR 1.17; 95% CI, 0.74-1.84). CONCLUSIONS These results suggest that side-effects of AIs such as musculoskeletal syndrome and sleep disorder lead to ET discontinuation within the first treatment year in significant numbers of EBC patients. Compliance programmes adapted for subgroups that are at risk for early non-persistence might help to ensure the recommended therapy duration. CLINICAL TRIALS NUMBER CFEM345DDE19.

Abstract
Human epidermal growth factor receptor 2 (HER2) is a central predictive biomarker in breast cancer. Inaccurate HER2 results in different laboratories could be as high as 20%. However, this statement is based on data generated more than 13 years ago and may not reflect the standards of modern diagnostic pathology. We compared central and local HER2 testing in a total of 1581 HER2-positive tumors from five clinical trials. We evaluated the clinical relevance for pathological complete response (pCR) and disease-free survival in a subgroup of 677 tumors, which received an anti-HER2 therapy. Over the period of 12 years, the discordance rate for HER2 decreased from 52.4 (GeparTrio) to 8.4% (GeparSepto). Discordance rates were significantly higher in hormone receptor (HR)-positive tumors (26.6%), compared to HR-negative tumors (16.3%, P<0.0001), which could be explained by a different distribution of HER2 mRNA levels in HR-positive and HR-negative tumors. pCR rates were significantly lower in discordant tumors (13.7%) compared to concordant tumors (32.2%, GeparQuattro and GeparQuinto, P<0.001). In survival analysis, tumors with discordant HER2 testing had a reduced overall survival (OS) in the HR-negative group (P=0.019) and a trend for improved OS in the HR-positive group (P=0.125). The performance of local HER2 testing was considerably improved over time and has reached a 92% concordance, which shows that quality initiatives in diagnostic pathology are working. Tumors with discordant HER2 testing had a reduced therapy response and different survival rates.

Abstract
Abstract
Background: Sentinel lymph node biopsy (SLNB) by radioactively labelled 99mTechnetium +/- patent blue is so far the current standard in SLN detection. However, it remains a time- and cost-consuming procedure requiring the availability of a nuclear medicine department and a precise coordination with the subsequent surgery. It could be desirable to empower surgeons to be independent from availability of a nuclear source and to spare patients from radioactivity. Indocyanine green (ICG) as a fluorescent coloring agent is already known as safe in diagnostics for heart, circulation, liver and eye disease and may represent a valid alternative to 99mTc and patent blue (PBD), especially as it does not cause aesthetic impairment of the breast, with ICG being only visible with near infra-red light.
Methods: This prospective, randomized study is a non-inferiority trial to evaluate ICG-fluorescence as an alternative to either 99mTc and/or patent blue dye for sentinel lymph node detection of primary breast cancer with and without neoadjuvant chemotherapy.
Patients, aged 18 - 80 years, with unilateral or bilateral, unifocal or multifocal/ multicentric primary breast cancer without signs of metastases and written consent are eligible for this study. ECOG status of 0-2 and life expectancy > 1 year is required. All BMI classes are admitted to the study, with predefined subgroups of a) <= 20 b) >20-30 c) >30-40 d) >40. Tumor stages included are a) Tis (>= 4 cm) b) T1 c) T2 and d) T3. ICG-guided SLNB may be applied in patients in the following settings: a) before neoadjuvant, b) after neoadjuvant chemotherapy.
Primary Endpoints: Rate of SLN detection by either of the methods in the following 3 arms of the trial:
Arm A: 99mTc + patent blue dye (PBD)
Arm B: 99mTc + indocyanine green (ICG)
Arm C: Indocyanine green (ICG)
Secondary Endpoints:
- Time to identify (TTI) sentinel lymph node(s) (min)
- Number of sentinel lymph nodes (SLN) and non-sentinel lymph nodes (non-SLN)
- Rate of concordance of detection by 99mTc+patent blue dye (PBD) vs. 99mTc + ICG
- Dose of radioactivity omitted in Arm C vs. Arm A & B
Results: This trial is in progress.

Abstract
Abstract
Background: The incidence of brain metastases (BM) in breast cancer patients is rising and has become a major clinical challenge. So far, the incidence of BM after modern neoadjuvant treatment is not clear.
Materials and Methods: In Geparquinto, patients with untreated HER2-positive breast cancer (n=615) received either lapatinib or trastuzumab, patients with HER2 negative breast cancer (n=1925) received bevacizumab in addition to an anthracycline and taxane-containing regimen and those not responding paclitaxel and everolimus (n=32). In Geparsixto, patients with HER2-positive tumors (n=273) received trastuzumab and lapatinib and patients with triple-negative tumors (n=315) received bevacizumab in addition to chemotherapy. We analyzed clinical factors associated with the occurrence of BM as first site of metastatic relapse after neoadjuvant treatment in both trials (n=3160).
Results: After a median follow-up of 61 months, 108 (3%) of a total of 3160 patients developed BM as first site of recurrence and 411 (13%) patients had distant metastases outside the brain. Brain metastases as first site of recurrence occurred later than other metastases (3--year-relapse free-rate 96.7% for patients who developed BM and 89.5% for patients who developed metastases outside the brain). Regarding subtypes of the primary tumor, 1% of luminal A (11/954), 2% of luminal B (7/381), 4% of HER2 positive (34/809) and 6% of triple-negative patients (56/1008) developed BM as first site of recurrence. In multivariate analysis, risk factors for the development of BM were larger tumor size (cT3-4; HR 1.9, 95%-CI 1.3-2.8, p=0.0022), node positive disease (HR 2.8, 95% CI 1.8-4.4, p<0.0001), no pCR after neoadjuvant chemotherapy (HR 2.7, 95% CI 1.6-4.7, p=0.0003) and HER2 positive (HR 3.8, 95% CI 1.9-7.8, p=0.0002) or triple-negative subtype (HR 8.1, 95% CI 4.2 – 15.8, p< 0.0001). Breast cancer subtype remained the most relevant risk factor for BM. Patients who developed BM were more often HER2 positive or triple-negative tumors compared with patients who developed metastases outside the brain (HER2 positive subtype 32 vs. 19%, triple-negative subtype 52 vs. 40%, p< 0.001).
Conclusion: Especially patients with HER2-positive and triple negative tumors are at risk of developing BM despite active systemic treatment. A better understanding of the underlying mechanisms is required in order to develop potential preventive strategies.

Abstract
Abstract
Background
Inhibition of COX-2 has been shown to attenuate the metastatic process in pre-clinical models of human breast cancer (BC). The primary aim of this study was to assess the effect of 2 years adjuvant therapy with the COX-2 inhibitor celecoxib compared with placebo in HER2-ve primary BC patients.
Patients & Methods
Patients were randomised in a 2:1 ratio to receive celecoxib 400mg once daily or placebo for 2 years. Patients had to have completely resected BC with prior local and systemic adjuvant treatment according to local practice. Concurrent radiotherapy was permitted and hormone receptor +ve patients received endocrine therapy according to local practice. Patients with HER2+ or node negative, T1 and grade 1 disease were excluded. Median age of patients was 55 years (IQR: 49-63). 50% of patients had tumours >2cm; 42% were grade 3; 48% had node +ve disease. According to local assessment 73% were ER/PgR +ve. Primary endpoint was Disease Free Survival (DFS); defined as time from randomisation to date of first event, with events contributing to analysis defined as recurrence (distant/local), new primary BC (ipsilateral/contralateral) and death. Secondary endpoints included Overall Survival (OS), toxicity, cardiovascular mortality and incidence of second primaries. Subgroup analysis by hormone receptor status was pre-planned. Survival endpoints are analysed using Cox-proportional hazards and log-rank tests; restricted mean survival is used where proportional hazards do not hold.
Results
Between January 2007 and November 2012, 2639 patients were randomised (1763 celecoxib; 876 placebo) from 181 centres across the UK and Germany. At 13th April 2017, median follow up was 60 months (IQR: 48-72) with 428 DFS events reported. Unadjusted survival analysis results are presented below, with hazard ratio<1 favouring celecoxib:
5 year survival estimate (95% CI)Hazard ratio (95% CI)p-valueDFS (all patients) Celecoxib83% (81, 85)1.02 (0.83 – 1.24)0.88Placebo83% (80, 86)1- DFS within ER+ Celecoxib87% (85, 89)0.89 (0.69 – 1.16)0.40Placebo86% (83, 89)1- DFS within ER- Celecoxib72% (68, 76)1.17 (0.85 – 1.61)0.33Placebo75% (69, 80)1- OS (all patients) Celecoxib90% (88, 91)0.97 (0.75 – 1.25)0.81Placebo90% (88, 92)1-
The interaction between ER status and treatment was not significant; p=0.36.
In the celecoxib and placebo groups there were 17 and 8 deaths respectively in patients who had not relapsed. These were due to cardiac (n=3; 2) and other (n=14; 6) in the celecoxib and placebo groups respectively; none were GI related. In total 304 serious adverse events were observed in 265 patients (186/1763 celecoxib; 79/876 placebo). In the celecoxib and placebo groups respectively these were related to cardiac (n=12; 7), GI (n=9; 2) and other (n=193; 81). Work is ongoing to determine whether a subset of ER+ patients whose primary tumours show the characteristics of a COX-2 signature receive greater benefit from celecoxib.
Conclusions
There is no benefit of celecoxib in the ITT population. Further exploratory studies focussing on the ER+ subpopulation are ongoing. Celecoxib treatment is not associated with significant toxicity when compared to placebo in this population of BC patients.

Abstract
INTRODUCTION Chest ultrasonography is routinely used in evaluation of chest trauma for diagnosis of pulmonary injury. This study aimed to evaluate the accuracy of B-Lines for diagnosing lung contusion in patients with blunt trauma of the chest. METHODS Trauma patients who met the inclusion criteria were enrolled in the study and underwent ultrasonography by trained emergency medicine residents. Ultrasound results were recorded in terms of number of B-lines and the existence of peripheral parenchymal lesion (PPL). After ultrasound, the patient underwent chest x-ray and chest CT scan (as reference test) and screening performance of B-lines and PPL were evaluated. RESULTS 147 patients underwent chest ultrasound. The mean age of the patients was 40.74 ± 18.6 (78.9% male). B-lines˃3 had 94.0% (95% CI: 83.45-98.75) sensitivity and 57.7% (95% CI: 47.3-67.7) specificity, B-lines˃6 had 90.0% (95% CI: 78.2-96.7) sensitivity and 93.81% (95% CI: 87.0-97.7) specificity, and PPL had 34.0% (95% CI: 21.2-48.8) sensitivity and 100% (95% CI: 96.3-100.0) specificity. Composite findings of B-lines˃6 + PPL had 92.0% (95% CI: 80.8-97. 8) sensitivity and 93.8% (95% CI: 87.0-97.7) specificity in the diagnosis of lung contusion. CONCLUSION PPL and B-Lines˃6 had the highest accuracy in detecting lung contusion. B-Line˃6 had high sensitivity and specificity and was easy to perform; thus, it seems that B-Line˃6 could be considered as an alternative screening tool in detection of lung contusion.

Abstract
Background Ketamine, as an opium alternative, has been proposed for pain relief in the emergency department (ED). Objectives This study was carried out to compare low dose ketamine (LDK) with morphine for pain relief in trauma patients. Methods In this randomized double-blinded clinical trial, 300 trauma patients from the ED of 2 teaching hospitals in Tehran, Iran were enrolled and randomly divided into 2 equal groups. The 1st group received 0.2 mg/kg of ketamine while the 2nd group received 0.1 mg/kg of intravenous morphine. The pain intensity and complications were measured and compared every 15 minutes to 1 hour. Results Fifteen minutes after drug injection in both groups, a significant reduction was found in average pain intensity compared to the initial pain (P = 0.01). At 15 minutes, no significant difference was found in both groups in regards to average pain intensity (P = 0.23). The average pain intensity at 30, 45, and 60 minutes in the group receiving morphine was lower than the ketamine group (P = 0.01, P < 0.001, P < 0.001 respectively). Two complications (drop in O2 saturation below 90% and flushing) were significantly greater in the morphine group. Conclusions The results of this study suggest that LDK, at a dose of 0.2 mg/kg, in the earlier minutes leads to significant reduction of pain when compared to that of intravenous morphine. It also created fewer complications than morphine.
