Abstract
Aims and Background Brain metastases confer a worse prognosis to breast cancer because they determine a severe increase in mortality. The aim of this study was to identify the early symptoms in patients with brain metastases after breast cancer treatment and to evaluate the median survival rate in women with single and operable brain lesions. Patients and Methods We examined 43 patients with brain metastases secondary to breast cancer treated in the Oncological Institute Prof I Chiricuţă, Cluj-Napoca, during the period 2000-2006. Results The median interval between the breast cancer diagnosis and detection of central nervous metastases was 21 months. The most frequent symptoms were headache, gait disturbance, nausea and vomiting. Patients with a single brain lesion had a median survival of 23 months compared to only 7 months in case of patients with multiple brain metastases. Conclusions The prognosis is worse in patients with solitary brain metastases secondary to breast cancer than in patients who present extracranial metastases. Among factors considered favorable in these patients are a single brain lesion, accessibility to surgery, and the absence of associated extracranial metastases.

Abstract
BACKGROUND To assess the efficacy and tolerability of Cisplatin plus Gemcitabine combination in patients with brain metastases (BM) from breast cancer (BC). MATERIALS AND METHODS Eighteen BC patients with BM who were treated with Cisplatin plus Gemcitabine regimen between 2003-2011 were evaluated. RESULTS A median of 6 cycles of this regimen were received, in fifteen patients (83.3%) as first-line chemotherapy, in 2 as second- line and in 1 as third-line after diagnosis of BM. Dose reduction was performed in 11 (61.1%) patients; major reasons were neutropenia and leukopenia. Grade III neutropenia and Grade II trombocytopenia rates were 33.3% and 16.7% respectively. Overall response rate (ORR; complete+partial response rate) was 33.4% (n=6) for the entire study population; triple negative patients achieved an 66.6% ORR while hormone receptor (HR) positive patients had 25% and HER2 positive patients 12.5%. Median progression-free survival was 5.6 months (2.4-8.8 months, 95%CI) and longer in patients with triple negative breast cancer (TNBC) (median 7.4 months, 95%CI, 2.4-12.3 months) than the patients with other subtypes (median 5 months for HER2 positive and 3.6 months for HR positive patients). Median PFS of the patients with TNBC who received this regimen as first-line was 9.2 months (5.2-13.2 months, 95%CI). CONCLUSIONS Cisplatin plus Gemcitabine may be a treatment option for patients with BM from breast cancer. Longer PFS and higher response rates are results that support the usage of this regimen especially for the triple negative subtype. However, further prospective and randomized trials are clearly required to provide more exact information.

Abstract
Brain metastases of breast cancer remain a difficult problem for clinical management. Their incidence appears to be increasing, which is likely due to longer survival times for advanced breast cancer patients as well as additional and improved tools for detection. Molecular features of tumors associated with this syndrome are not yet understood. In general, survival may be improving for brain metastases due to better local control in the CNS, as well as improvements in systemic disease management. Selected patients with brain metastases are able to undergo surgical resection, which has been associated with extended disease control in some patients. However, whole-brain radiation has been the mainstay for treatment for most patients. Stereotactic radiosurgery is playing an increasing role in the primary treatment of brain metastases, as well as for salvage after whole-brain radiation. Recent series have reported median survivals of 13 months or longer with stereotactic radiosurgery. Further improvements in radiation-based approaches may come from ongoing studies of radiosensitizing agents. The ability of systemic treatments to impact brain metastases has been debated, and specific treatment regimens have yet to be defined. New approaches include chemotherapy combinations, biologic therapies and novel drug-delivery strategies.

Abstract
BACKGROUND There are no clinically useful biomarkers predictive of brain metastases (BM) in breast cancer. In this study, we investigated the correlation between expression of selected proteins in the primary tumor and the risk of BM in patients with metastatic breast cancer (MBC). METHODS The study included 198 MBC patients (96 with and 102 without BM). Using tissue microarrays derived from the primary tumor, we assessed by immunohistochemical expression of ER, PR, HER2, Ki-67, CK5/6, EGFR, HER3, CXCR4, Rad51, E-cadherin, and claudin 3 and 4. RESULTS Ki-67 ≥14% (hazard ratio [HR] 2.76; P < 0.001), cytoplasmic expression of Rad51 (HR 1.87; P = 0.014) and ER-negativity (HR 1.72; P = 0.029) were associated with increased risk of BM in the multivariate analysis. A three-biomarker profile including ER, Ki-67 and Rad51 vs. other subtypes combined yielded an HR of 4.43 (P < 0.001). CONCLUSIONS ER-negativity, cytoplasmic expression of Rad51 and high Ki-67 are associated with increased risk of BM.

Abstract
Brain metastases are a frequent complication of many systemic cancers and portend a poor prognosis. This retrospective analysis of health claims data compared survival, treatment and health care utilization and costs in patients with brain metastasis by primary tumor site. Adult commercial and Medicare Advantage enrollees newly diagnosed with brain metastasis in 01 Jan 2004 through 30 Apr 2010 were identified. Inclusion required at least 2 claims that identified the same primary cancer site prior to diagnosis of brain metastasis and no evidence of primary brain tumors. Health care utilization rates and costs were calculated at the patient level for each month of follow-up. Differences among primary cancer site cohorts were assessed by ANOVA (continuous variables), Chi square test (proportions) and the Poisson distribution (utilization rates). The primary cancer cohorts comprised 1,031 lung cancer, 93 melanoma and 395 female breast cancer patients. During the 6 months prior to brain metastasis diagnosis, 59 % of lung cancer patients had no evidence of lymph node involvement or other metastatic disease compared to 55 and 42 % of melanoma and breast cancer patients (P < 0.001). Survival after brain metastasis diagnosis was less than 3 months for 52, 43 and 39 % for lung cancer, breast cancer and melanoma, respectively (P < 0.001). Melanoma patients had the highest rate of inpatient stays and outpatient visits (P ≤ 0.003). Total monthly all-cause costs were: melanoma, $23,426; breast cancer $19,708; lung cancer, $17,007 (P = 0.003). Health care utilization and costs after brain metastasis diagnosis were substantial and differed by primary tumor site.

Abstract
With therapies for systemic malignancy improving, life expectancy for cancer patients is becoming increasingly dependent on control of brain metastatic disease. Despite improvements in surgical and radiotherapy modalities for control of brain metastasis, the prognosis for patients with brain metastases is poor. The development of controlled release polymers has lead to novel new therapies for malignant brain tumors consisting of direct surgical delivery of chemotherapy agents to the tumor bed and sustained chemotherapy release over a prolonged period of time. Although there is a large body of literature in support of BCNU polymer wafer for primary brain malignancy and experimental brain metastases, clinical studies evaluating the BCNU polymer wafer for brain metastatic disease are relatively sparse. In this review, we discuss the role of the BCNU polymer wafer for brain metastasis focusing specifically on rationale for use of locally delivered sustained release polymers, history of the BCNU polymer wafer, and emerging studies examining the role of the BCNU polymer wafer for metastatic brain tumors.

Abstract
Currently, survival of breast cancer patients with brain metastasis ranges from 2 to 16 months. In experimental brain metastasis studies, only 10% of lesions with the highest permeability exhibited cytotoxic responses to paclitaxel or doxorubicin. Therefore, radiation is the most frequently used treatment, and sensitizing agents, which synergize with radiation, can improve the efficacy of the therapy. In this study we used 435-Br1 cells containing the fluorescent protein (eGFP) gene and the photinus luciferase (PLuc) gene to develop a new brain metastatic cell model in mice through five in vivo/in vitro rounds. BR-eGFP-CMV/Luc-V5 brain metastatic cells induce parenchymal brain metastasis within 60.8 ± 13.8 days of intracarotid injection in all mice. We used this model to standardize a preclinical chemoradiotherapy protocol comprising three 5.5 Gy fractions delivered on consecutive days (overall dose of 16.5 Gy) which improved survival with regard to controls (60.29 ± 8.65 vs. 47.20 ± 11.14). Moreover, the combination of radiotherapy with temozolomide, 60 mg/Kg/day orally for five consecutive days doubled survival time of the mice 121.56 ± 52.53 days (Kaplan-Meier Curve, p < 0.001). This new preclinical chemoradiotherapy protocol proved useful for the study of radiation response/resistance in brain metastasis, either alone or in combination with new sensitizing agents.

Abstract
BACKGROUND AND OBJECTIVES Triple-negative breast cancer (TNBC) has a poor prognosis and overall survival (OS) compared to other types of breast cancer tumors. However, there is to date no evidence that this is also the case in Saudi Arabia. DESIGN AND SETTING Retrospective review of breast cancer patients who were treated from January 2001 to December 2008 (517 patients) at the King AbdulAziz Medical City, Riyadh, Saudi Arabia. PATIENTS AND METHODS Patients were selected as TNBC if all three markers of estrogen receptor (ER), progesterone receptor (PR) and the human epidermal growth factor (HER2) tested by immunohistochemistry as negative. They were then age- and stage-matched, and compared with non-TNBC patients to examine differences, if any, in their clinicopathologic features, prognosis and OS. RESULTS Twenty-six patients with a follow up time of at least three years were identified as TNBC. Thirty-three patients who were age- and stage-matched were selected as the non-TNBC controls. Clinicopathologic results illustrated significantly more grade 3 tumors (P=.02) and CK 5/6 expression (P<.001) in the TNBC group compared to the non-TNBC group. TNBC patients aged ≤40 years showed a significantly worse prognosis and OS compared to TNBC patients aged >40 years (P=.01), and when compared to the non-TNBC group (P=.04). CONCLUSION The incidence of TNBC in our cohort is similar to what has been illustrated in previous studies in Western population. There was no significant difference in 3-year survival between TNBC and non-TNBC groups. However, the aggressiveness of this type of tumor and OS is significantly higher in younger patients aged ≤40 years, compared to those over 40 years of age.

Abstract
EUSOMA (The European Society of Breast Cancer Specialists) is committed to writing recommendations on different topics of breast cancer care which can be easily adopted and used by health professionals dedicated to the care of patients with breast cancer in their daily practice. In 2011, EUSOMA identified the management of young women with breast cancer as one of the hot topics for which a consensus among European experts was needed. Therefore, the society recently organised a workshop to define such recommendations. Thirteen experts from the different disciplines met for two days to discuss the topic. This international and multidisciplinary panel thoroughly reviewed the literature in order to prepare evidence-based recommendations. During the meeting, two working groups were set up to discuss in detail diagnosis and loco-regional and systemic treatments, including both group aspects of psychology and sexuality. The conclusions reached by the working groups were then discussed in a plenary session to reach panel consensus. Whenever possible, a measure of the level of evidence (LoE) from 1 (the highest) to 4 (the lowest) degree, based on the methodology proposed by the US Agency for Healthcare Research and Quality (AHRQ), was assigned to each recommendation. The present manuscript presents the recommendations of this consensus group for the management of young women with breast cancer in daily clinical practice.

Abstract
Melanoma brain metastasis that develops as the isolated first visceral site challenges the current paradigm of tumor progression in which brain metastasis is regarded as the final stage. Here we test the hypothesis that melanoma patients who develop brain metastasis as the isolated first visceral site have distinct clinicopathological features at the time of primary melanoma diagnosis. Cutaneous melanoma patients enrolled in 2 prospectively collected databases were studied (Cohort 1: 1972-1982, Cohort 2: 2002-2009). Patients who developed brain metastasis as isolated first visceral site were compared with (1) all other patients, (2) patients who developed visceral metastasis: extracranial only or extracranial and brain, and (3) patients who progressed to other isolated visceral sites first. Two hundred seven of 2280 (9.1%) patients developed brain metastasis (median follow-up, 5.2 y). Seventy-four of 207 (35.7%) brain metastasis patients progressed to brain metastasis as the isolated first visceral site. These patients presented with primaries that were thinner and had no mitosis compared with all other visceral metastasis patients (Fisher's combined P = .02, .05, respectively), and there was a significant difference in American Joint Committee on Cancer stage distribution at initial melanoma diagnosis (combined P = .02). Post-visceral metastasis survival, however, was shorter in patients with brain metastasis as isolated first visceral site than in patients with visceral metastasis: extracranial and brain (combined P = .03). Brain metastasis as isolated first visceral site is a distinct clinicopathological entity. Studies are needed to better understand the biological factors driving this phenotype at the time of primary melanoma diagnosis and to determine its clinical implications.

Abstract
BACKGROUND This retrospective study sought to define the incidence of brain metastases as a first site of recurrence among women with triple receptor-negative breast cancer (TNBC). METHODS A total of 2448 patients with stage I through III TNBC who were diagnosed between 1990 and 2010 were identified. We computed the cumulative incidence of developing brain metastases as a first site of recurrence at 2 and 5 years. Cox proportional hazards models were fitted to determine factors that could predict for the development of brain metastases as a first site of recurrence. The Kaplan-Meier product limit method was used to compute survival following a diagnosis of brain metastases. RESULTS At a median follow-up of 39 months, 115 (4.7%) patients had developed brain metastases as a first site of recurrence. The cumulative incidence at 2 and 5 years was 3.7% (95% confidence interval [CI] = 2.9%-4.5%) and 5.4% (95% CI = 4.4%-6.5%), respectively. Among patients with stage I, II, and III disease, the 2-year cumulative incidence of brain metastases was 0.8%, 3.1%, and 8%, respectively (P < .0001). The 5-year cumulative incidence was 2.8%, 4.6%, and 9.6% among patients with stage I, II, and III disease, respectively (P < .0001). In the multivariable model, patients with stage III disease had a significant increase in the risk of developing brain metastases as a first site of recurrence (hazards ratio = 3.51; 95% CI = 1.85-6.67; P = .0001) compared to patients with stage I disease. Those with stage II disease had a nonsignificant increased risk of developing brain metastases as a first site of recurrence (hazards ratio = 1.61; 95% CI = 0.92-2.81; P = .10) compared with patients with stage I disease. Median survival following a diagnosis of brain metastases was 7.2 months (range, 5.7-9.4 months). CONCLUSIONS Patients with nonmetastatic TNBC have a high early incidence of developing brain metastases as a first site of recurrence, which is associated with subsequent poor survival. Patients with stage III TNBC in particular would be an ideal cohort in which to research preventive strategies.

Abstract
This study evaluated the expression of biological markers of breast cancers with brain metastases. Eighteen paired tumors were assessed, with 42 non-brain-metastasizing breast cancers that were stained with ER, PR, HER2, CK5/6, p63, and Ki67, and were also classified into intrinsic subtypes. The expression patterns between the breast tumors with brain metastases were compared to the brain metastases and the controls. Breast cancers with brain metastases were of higher grade and showed higher incidence of lymph node metastases at initial diagnosis and higher EGFR, p63, and Ki67 expression. In the group of breast cancers with brain metastases, the brain metastases showed higher HER2, CK5/6, and Ki67 expression compared to the breast primaries. There was also a higher incidence of basal subtype and a lower incidence of luminal subtype. When tumors metastasized, changes in hormonal receptor (22%) and HER2 (6%) status were observed. We concluded that breast cancers with higher grade, lymph node involvement at diagnosis, high EGFR, p63, and Ki67 expression, and of basal subtype were at higher risk for brain metastases, and that both hormonal receptors and HER2 status may change in brain metastases.

A 10-year-old female spayed Shih Tzu dog was diagnosed with secondary IMC. At necropsy, brain metastasis of mammary neoplastic cells was observed in tissues of the cerebrum and cerebellum. Metastases were also found in other distant organs such as heart, lung, liver, spleen, and inguinal lymph node. There is limited data about the metastasis of IMC and its pattern. The current report of IMC with brain metastases contributes to the understanding of metastatic IMC.

Abstract
The increasing incidence of breast cancer brain metastasis in patients with otherwise well-controlled systemic cancer is a key challenge in cancer research. It is necessary to understand the properties of brain-tropic tumor cells to identify patients at risk for brain metastasis. Here we attempt to identify functional phenotypes that might enhance brain metastasis. To obtain an accurate classification of brain metastasis proteins, we mapped organ-specific brain metastasis gene expression signatures onto an experimental protein-protein interaction network based on brain metastatic cells. Thirty-seven proteins were differentially expressed between brain metastases and non-brain metastases. Analysis of metastatic tissues, the use of bioinformatic approaches, and the characterization of protein expression in tumors with or without metastasis identified candidate markers. A multivariate analysis based on stepwise logistic regression revealed GRP94, FN14, and inhibin as the best combination to discriminate between brain and non-brain metastases (ROC AUC = 0.85, 95% CI = 0.73 to 0.96 for the combination of the three proteins). These markers substantially improve the discrimination of brain metastasis compared with ErbB-2 alone (AUC = 0.76, 95% CI = 0.60 to 0.93). Furthermore, GRP94 was a better negative marker (LR = 0.16) than ErbB-2 (LR = 0.42). We conclude that, in breast carcinomas, certain proteins associated with the endoplasmic reticulum stress phenotype are candidate markers of brain metastasis.

Abstract
BACKGROUND Central nervous system (CNS) metastases are a common occurrence in patients with breast cancer and are identified in up to 30% of patients at autopsy. OBJECTIVE To determine population-based estimates of survival times after surgical intervention for Medicare patients with metastatic breast cancer to the brain and spinal column. METHODS Female breast cancer patients with metastases to the brain and spinal column and undergoing neurosurgical treatment were identified through the Surveillance, Epidemiology, and End Results-Medicare database. Estimates of survival were calculated with Kaplan-Meier estimation and a Cox proportional hazards model. RESULTS There were 643 patients who underwent neurosurgical treatment of metastatic disease from 1986 to 2005. Of these patients, 264 underwent cranial surgery and 379 underwent spinal surgery. There were 40 deaths during the postoperative hospital admission for an inpatient postoperative death rate of 6.2%. Inpatient death has declined by approximately 50% for surgeries performed in the most recent decade; however, the 30-day mortality rate of 9.0% has remained constant. The median postoperative survival after cranial surgery was 7.8 months (95% confidence interval, 6.2-9.2), after laminectomy was 9.4 months (95% confidence interval, 6.3-15.7), and after spinal fusion was 15.7 months (95% confidence interval, 11.9-18.5). Survival after spinal fusion has increased by approximately 50% in the recent decade. Patients with increased survival after cranial surgery were younger, had fewer comorbidities, and had longer periods from breast cancer diagnosis to surgery. Patients with increased survival after spinal neurosurgery had lower-grade lesions and longer time periods from breast cancer diagnosis to surgical treatment. CONCLUSION After surgically treated metastases, one-third of cranial patients and one-half of spinal patients are alive at 1 year. The overall postoperative survival has increased over time only for spinal fusion procedures.

Abstract
BACKGROUND Survival of patients suffering from cerebral metastases (CM) is limited. Identification of patients with a high risk for CM is warranted to adjust follow-up care and to evaluate preventive strategies. PATIENTS AND METHODS Exploratory analysis of disease-specific parameter in patients with metastatic breast cancer (MBC) treated between 1998 and 2008 using cumulative incidences and Fine and Grays' multivariable regression analyses. RESULTS After a median follow-up of 4.0 years, 66 patients (10.5%) developed CM. The estimated probability for CM was 5%, 12% and 15% at 1, 5 and 10 years; in contrast, the probability of death without CM was 21%, 61% and 76%, respectively. A small tumor size, ER status, ductal histology, lung and lymph node metastases, human epidermal growth factor receptor 2 positive (HER2+) tumors, younger age and M0 were associated with CM in univariate analyses, the latter three being risk factors in the multivariable model. Survival was shortened in patient developing CM (24.0 months) compared with patients with no CM (33.6 months) in the course of MBC. CONCLUSION Young patients, primary with non-metastatic disease and HER2+ tumors, have a high risk to develop CM in MBC. Survival of patients developing CM in the course of MBC is impaired compared with patients without CM.

Abstract
Central nervous system (CNS) or brain metastasis is an emerging area of interest in organ-specific metastasis research. Lung and breast cancers are the most common types of primary tumors to develop brain metastases. This disease complication contributes significantly to the morbidity and mortality of both of these common cancers; as such, brain metastasis is designated an unmet medical need by the US Food and Drug Administration (FDA). Recently, an increase in incidence of CNS disease has been noted in the literature for breast cancer, while it has been an ongoing major complication from lung cancer. Progress in treating brain metastases has been hampered by a lack of model systems, a lack of human tissue samples, and the exclusion of brain metastatic patients from many clinical trials. While each of those is significant, the major impediment to effectively treating brain metastatic disease is the blood-brain barrier (BBB). This barrier excludes most chemotherapeutics from the brain and creates a sanctuary site for metastatic tumors. Recent findings on the biology of this disease and translational leads identified by molecular studies are discussed in this article.

Abstract
Due to improvements in diagnosis and systemic therapy, brain metastases are an increasingly common cause of morbidity and mortality for patients with advanced breast cancer. The incidence of symptomatic brain metastases among women with metastatic breast cancer ranges from 10% to 16%. The HER2 receptor, which is overexpressed in approximately 25% of all breast cancers, is an important risk factor for the development of central nervous system metastases. Surgery and radiation therapy are the primary approaches to the treatment of brain metastases but new chemotherapy and biological agents promise to play an important role in the future management of central nervous system disease. This article reviews the epidemiology, current treatment options and recent advances in the field, with a focus on HER2-positive disease and the emerging role of lapatinib for the treatment and prevention of brain metastases.

Abstract
Metastasis to the central nervous system (CNS), including neoplastic meningitis (NM), is a devastating complication of systemic cancer. With the improved survival of cancer patients, the incidence of CNS metastasis is rising, especially among those with breast or lung carcinoma. New therapies that effectively treat these primary tumors outside of the CNS have underscored the significance of CNS metastases; they have become a significant clinical issue and a therapeutic challenge. This review discusses clinical situations in which treatment or chemoprophylaxis of CNS metastases and NM from breast or lung cancer may play an important role. Potential clinical trials to assess these assumptions also will be proposed.

Abstract
PURPOSE To determine the incidence, outcomes, and current strategies for management of brain metastases in patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer. METHODS A literature review was performed to obtain data on central nervous system metastases in patients with breast cancer. RESULTS HER2 amplification/overexpression is a prognostic and predictive factor for the development of CNS metastases. Autopsy data show that the incidence rate for CNS metastases in patients with breast cancer is approximately 30%; this may be higher (ie, 30% to 50%) in patients with HER2-positive disease. Treatment with trastuzumab is not associated with an increased incidence of CNS metastases. Data from three phase III adjuvant trials showed the incidence was similar between patients who received trastuzumab and those who did not. Furthermore, trastuzumab can significantly improve overall survival in HER2-positive patients who already have CNS metastases compared with patients who do not receive trastuzumab or those who have HER2-negative brain metastases. This survival advantage is conferred via systemic control of the disease. The current standard of care for patients with CNS metastases is whole-brain radiotherapy (WBRT), with or without surgery, or stereotactic radiosurgery. In the future, novel therapies or combinations of therapies may additionally improve survival in these patients. CONCLUSION The incidence of CNS metastases in trastuzumab-treated patients is similar to that in all patients with HER2-positive disease. Trastuzumab can improve survival in patients with HER2-positive disease with CNS metastases.

Abstract
Brain metastases of breast cancer seem to be increasingin incidence as systemic therapy improves. Metastatic disease in the brain is associated with high morbidity and mortality. We present the first gene expression analysis of laser-captured epithelial cells from resected human brain metastases of breast cancer compared with unlinked primary breast tumors. The tumors were matched for histology, tumor-node-metastasis stage, and hormone receptor status. Most differentially expressed genes were down-regulated in the brain metastases, which included, surprisingly, many genes associated with metastasis. Quantitative real-time PCR analysis confirmed statistically significant differences or strong trends in the expression of six genes: BMP1, PEDF, LAMgamma3, SIAH, STHMN3, and TSPD2. Hexokinase 2 (HK2) was also of interest because of its increased expression in brain metastases. HK2 is important in glucose metabolism and apoptosis. In agreement with our microarray results, HK2 levels (both mRNA and protein) were elevated in a brain metastatic derivative (231-BR) of the human breast carcinoma cell line MDA-MB-231 relative to the parental cell line (231-P) in vitro. Knockdown of HK2 expression in 231-BR cells using short hairpin RNA reduced cell proliferation when cultures were maintained in glucose-limiting conditions. Finally, HK2 expression was analyzed in a cohort of 123 resected brain metastases of breast cancer. High HK2 expression was significantly associated with poor patient survival after craniotomy (P = 0.028). The data suggest that HK2 overexpression is associated with metastasis to the brain in breast cancer and it may be a therapeutic target.

Abstract
PURPOSE Evaluation of the influence of immunohistochemically defined breast cancer (BC) subtypes and other risk factors on the development of cerebral metastases (CM). METHODS Exploratory analysis of a hospital-based prospective tumour registry including all patients with primary BC treated in our EUSOMA breast unit between 1998 and 2006. RESULTS The study cohort contained 2441 patients, including 284 patients (11.6%) with triple-negative (oestrogen receptor (ER), progesterone receptor (PR) and HER2-negative) and 245 patients (10.1%) with HER2-overexpressing BC subtypes. Overall, 80 patients (3.3%) developed CM within a median follow-up period of 47 months, 19 (23.8%) of them with triple-negative and 19 (23.8%) with HER2-positive tumours. Therefore, 6.7% of all patients with triple-negative and 7.8% of patients with HER2-positive breast cancer developed CM. Multivariate analysis indicated that the highest risk for CM was triple-negative breast cancer. Further independent risk factors were: HER2-overexpression, early onset BC (age<50 years), and large tumour size (pT3/4). Among those patients developing CM, triple-negative BC showed the shortest interval between primary diagnosis and occurrence of CM with a median of 22 months, compared to 30 and 63.5 months in HER2-positive and ER+/HER2- BC, respectively. Survival after occurrence of CM did not differ among the subtypes. CONCLUSION Patients with triple-negative or HER2-positive BC have a higher risk for CM compared with patients bearing the ER+/HER2- phenotype and develop CM earlier in the course of disease. A risk profile for CM might help adjust surveillance in high risk populations and identify patients with a need for new treatment strategies.

Abstract
BACKGROUND The brain is increasingly being recognized as a sanctuary site for metastatic tumor cells in women with HER2-overexpressing breast cancer who receive trastuzumab therapy. There are no approved or widely accepted treatments for brain metastases other than steroids, cranial radiotherapy, and surgical resection. We examined the efficacy of lapatinib, an inhibitor of the epidermal growth factor receptor (EGFR) and HER2 kinases, for preventing the outgrowth of breast cancer cells in the brain in a mouse xenograft model of brain metastasis. METHODS EGFR-overexpressing MDA-MB-231-BR (231-BR) brain-seeking breast cancer cells were transfected with an expression vector that contained or lacked the HER2 cDNA and used to examine the effect of lapatinib on the activation (ie, phosphorylation) of cell signaling proteins by immunoblotting, on cell growth by the tetrazolium salt 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay, and on cell migration using a Boyden chamber assay. The outgrowth of large (ie, >50 microm(2)) and micrometastases was counted in brain sections from nude mice that had been injected into the left cardiac ventricle with 231-BR cells and, beginning 5 days later, treated by oral gavage with lapatinib or vehicle (n = 22-26 mice per treatment group). All statistical tests were two-sided. RESULTS In vitro, lapatinib inhibited the phosphorylation of EGFR, HER2, and downstream signaling proteins; cell proliferation; and migration in 231-BR cells (both with and without HER2). Among mice injected with 231-BR-vector cells, those treated with 100 mg lapatinib/kg body weight had 54% fewer large metastases 24 days after starting treatment than those treated with vehicle (mean number of large metastases per brain section: 1.56 vs 3.36, difference = 1.80, 95% confidence interval [CI] = 0.92 to 2.68, P < .001), whereas treatment with 30 mg lapatinib/kg body weight had no effect. Among mice injected with 231-BR-HER2 cells, those treated with either dose of lapatinib had 50%-53% fewer large metastases than those treated with vehicle (mean number of large metastases per brain section, 30 mg/kg vs vehicle: 3.21 vs 6.83, difference = 3.62, 95% CI = 2.30 to 4.94, P < .001; 100 mg/kg vs vehicle: 3.44 vs 6.83, difference = 3.39, 95% CI = 2.08 to 4.70, P < .001). Immunohistochemical analysis revealed reduced phosphorylation of HER2 in 231-BR-HER2 cell-derived brain metastases from mice treated with the higher dose of lapatinib compared with 231-BR-HER2 cell-derived brain metastases from vehicle-treated mice (P < .001). CONCLUSIONS Lapatinib is the first HER2-directed drug to be validated in a preclinical model for activity against brain metastases of breast cancer.

Abstract
BACKGROUND Breast cancer central nervous system (CNS) metastases are an increasingly important problem because of high CNS relapse rates in patients treated with trastuzumab and/or taxanes. PATIENTS AND METHODS We evaluated data from 2887 node-positive breast cancer patients randomised in the BIG 02-98 trial comparing anthracycline-based adjuvant chemotherapy (control arms) to anthracycline-docetaxel-based sequential or concurrent chemotherapy (experimental arms). After a median follow-up of 5 years, 403 patients had died and detailed information on CNS relapse was collected for these patients. RESULTS CNS relapse occurred in 4.0% of control patients and 3.7% of docetaxel-treated patients. CNS relapse occurred in 27% of deceased patients in both treatment groups. CNS relapse was usually accompanied by neurologic symptoms (90%), and 25% of patients with CNS relapse died without evidence of extra-CNS relapse. Only 20% of patients survived 1 year from the diagnosis of CNS relapse. Prognosis of CNS relapse was worse for patients with meningeal carcinomatosis when compared with brain metastases. Unexpected findings included a higher rate of positive cerebrospinal fluid cytology (8% versus 3%) and more frequent use of magnetic resonance imaging for diagnosis (47% versus 30%) in the docetaxel-treated patients. CONCLUSION There is no evidence that adjuvant docetaxel treatment is associated with an increased frequency of CNS relapse.

Abstract
PURPOSE To define the safety and efficacy of carmustine polymer wafers when added to a regimen of surgery and external beam radiotherapy for treatment of a single brain metastasis. EXPERIMENTAL DESIGN Adult patients underwent craniotomy for a single brain metastasis, and carmustine polymer wafers were placed in the tumor resection cavity. Patients then received whole-brain radiotherapy and were followed for patterns of recurrence in the central nervous system, toxicity, and survival. RESULTS We enrolled 25 patients with solitary brain metastases from lung (13 patients), melanoma (4 patients), breast (3 patients), and renal carcinoma (3 patients). Two patients had severe adverse events thought to be related to wafer placement, one with seizures alone, and one with seizures and subsequent respiratory compromise. Both responded to medical therapy. There were no wound infections. The local recurrence rate was surprisingly low (0%). Four patients (16%) relapsed elsewhere in the brain, and two patients (8%) relapsed in the spinal cord. Median survival was 33 weeks; 33% of patients survived 1 year, and 25% survived 2 years. CONCLUSIONS The addition of local chemotherapy delivered via carmustine polymer wafers to a regimen of surgical resection and external beam radiotherapy was well tolerated by patients undergoing surgery for a single brain metastasis. There were no local recurrences, suggesting that this treatment further reduced the risk of local relapse.

Abstract
Between 100,000 and 170,000 patients with cancer develop central nervous system (CNS) metastases each year in the U.S., of which approximately 20% carry a primary diagnosis of breast cancer. As a consequence of improvements in systemic therapy, which have allowed patients to live longer with advanced cancer, CNS metastases are emerging as an important sanctuary site, and the incidence may be increasing in patients with particular tumor subtypes. Unless there are improvements in the treatment of CNS disease, a growing proportion of patients may be at risk of experiencing both morbidity and mortality as a result of uncontrolled CNS progression, often at a time when their extra-CNS disease is apparently under control. This article reviews changes in the epidemiology and natural history of women with brain metastases from HER2-positive breast cancer over the last decade and presents the therapeutic challenges and opportunities that have arisen in this setting. First, the apparent increase in CNS disease among women with HER2-positive breast cancer, relative to historical controls, is discussed, followed by consideration of potential causes of this observation. Next, the implications of CNS disease, in terms of prognosis and the potential development of preventive strategies are considered. Finally, new developments in systemic approaches to the treatment of CNS disease, including cytotoxic chemotherapy and targeted therapy, are explored.

Abstract
Retrospective studies of breast cancer patients suggest that primary tumor Her-2 overexpression or trastuzumab therapy is associated with a devastating complication: the development of central nervous system (brain) metastases. Herein, we present Her-2 expression trends from resected human brain metastases and data from an experimental brain metastasis assay, both indicative of a functional contribution of Her-2 to brain metastatic colonization. Of 124 archival resected brain metastases from breast cancer patients, 36.2% overexpressed Her-2, indicating an enrichment in the frequency of tumor Her-2 overexpression at this metastatic site. Using quantitative real-time PCR of laser capture microdissected epithelial cells, Her-2 and epidermal growth factor receptor (EGFR) mRNA levels in a cohort of 12 frozen brain metastases were increased up to 5- and 9-fold, respectively, over those of Her-2-amplified primary tumors. Co-overexpression of Her-2 and EGFR was also observed in a subset of brain metastases. We then tested the hypothesis that overexpression of Her-2 increases the colonization of breast cancer cells in the brain in vivo. A subclone of MDA-MB-231 human breast carcinoma cells that selectively metastasizes to brain (231-BR) overexpressed EGFR; 231-BR cells were transfected with low (4- to 8-fold) or high (22- to 28-fold) levels of Her-2. In vivo, in a model of brain metastasis, low or high Her-2-overexpressing 231-BR clones produced comparable numbers of micrometastases in the brain as control transfectants; however, the Her-2 transfectants yielded 3-fold greater large metastases (>50 microm(2); P < 0.001). Our data indicate that Her-2 overexpression increases the outgrowth of metastatic tumor cells in the brain in this model system.

Abstract
Primary brain tumours of a single histological type and metastatic brain tumours are well described in dogs in the current veterinary literature. However, the concurrent presence of a primary and secondary tumour in the brain of a dog has never, to the authors' knowledge, been previously reported. The clinical and pathological features of a nine-year-old, female boxer with an oligodendroglioma and metastases from a mammary gland adenocarcinoma occurring simultaneously in the brain are described in this case report. Information in the veterinary literature on multiple malignancies affecting the central nervous system is very limited; therefore, a discussion about comparative situations in human medicine has been included.

Abstract
Brain metastases continue to be a major and growing challenge in oncology, but recent advances in surgery, radiosurgery, and chemotherapy have broadened the number of treatment options. Current approaches to the management of brain metastases focus on individualizing patient care based on factors including the Karnofsky Performance Status, the tumor histology, the number of metastases, and the status of the systemic disease. A number of treatment approaches have been shown to be effective for brain metastases, including surgery; radiosurgery; whole-brain radiotherapy; and, more recently, chemotherapy. The use of adjuvant whole-brain radiotherapy with local therapies, such as surgery or radiosurgery, along with newer chemotherapy options, such as targeted biological agents, temozolomide, and implantable 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) Gliadel wafers, are at the forefront of recent advances in the treatment of patients with brain metastases that may provide longer survival and improved quality of life. Although there is no current standard treatment, some general guidelines are recommended for single metastases, oligometastases (two to three brain metastases), and multiple (four or more) brain metastases, and for new or recurrent disease. With advances in systemic therapy for cancer, the treatment of brain metastases is becoming an increasingly important determinant of the length of survival and quality of life for cancer patients.

Abstract
BACKGROUND There is anecdotal evidence that the incidence of central nervous system (CNS) metastases in breast cancer patients is increasing. It is unclear whether specific tumor biological properties or the use of systemic therapies influence this risk. METHODS Using a database of 10,782 patients, 2685 patients were identified who experienced recurrence distantly. Clinical and biological features were analyzed in 2 ways: (1) patients who ever had versus those who never had CNS metastases, and (2) CNS metastases as the first site of recurrence versus those who had other sites. Correlations of survival after CNS metastasis with clinical and biologic features were also analyzed. RESULTS In the ever versus never analysis, CNS metastases were significantly associated with younger age, premenopausal status, infiltrating ductal carcinoma histology (IDC), estrogen receptor (ER) and progesterone receptor (PR) negativity, low Bcl-2, high S-phase, aneuploidy, and altered p53. Tumor size, lymph node status, and use of adjuvant systemic therapy played little role. HER-2 overexpression was not associated with an increased risk in these patients (none of whom were treated with trastuzumab) (P = .91). However, epidermal growth factor receptor (EGFR) overexpression was associated with increased risk (P = .02). A multivariate analysis revealed ER negativity (odds ratio [OR] 2.8, P < .001), IDC histology (OR 2.5, P = .02), and young age (P < .001) as independent factors for CNS metastases. The clinical and biologic profiles of primary tumors with CNS metastases at first recurrence did not differ from those with CNS metastases after recurrence to other sites, except for HER-2 status. HER-2-positive tumors were not more likely to undergo recurrence initially in the CNS (P =.04). The median survival after CNS metastases was 5.5 months and HER-2-positive patients had a shorter survival. CONCLUSIONS Younger patients with hormone receptor-negative, highly proliferative, genomically unstable, and p53-altered tumors were at increased relative risk for CNS metastases. HER-2 expression and adjuvant systemic therapies did not increase this risk.
