Brain metastasis breast cancer

Ibiayi Dagogo-Jack, Corey M Gill, Daniel P Cahill, Sandro Santagata, Priscilla K Brastianos
Development of brain metastasis (BM) portends a dismal prognosis for patients with cancer. Melanomas and carcinomas of the lung, breast, and kidney are the most common malignancies to metastasize to the brain. Recent advances in molecular genetics have enabled the identification of actionable, clinically relevant genetic alterations within primary tumors and their corresponding metastases. Adoption of genotype-guided treatment strategies in the management of systemic malignancy has resulted in dramatic and durable responses...

BACKGROUND: Triple Negative Breast Cancer (TNBC) is defined by a lack of estrogen and progesterone receptor gene expression and by the absence of overexpression on HER2. It is associated to a poor prognosis. We propose to analyze the clinicopathologic and prognostic characteristics of this breast cancer subtype in a Mediterranean population originated or resident in the North of Morocco. METHODS: We conducted a retrospective study of 279 patients diagnosed with breast cancer between January 2010 and January 2015...

Cellular MRI involves sensitive visualization of iron-labeled cells in vivo but cannot differentiate between dead and viable cells. Bioluminescence imaging (BLI) measures cellular viability, and thus we explored combining these tools to provide a more holistic view of metastatic cancer cell fate in mice. Human breast carcinoma cells stably expressing Firefly luciferase were loaded with iron particles, injected into the left ventricle, and BLI and MRI were performed on days 0, 8, 21 and 28. The number of brain MR signal voids (i...

: Tumor-derived exosomes are emerging mediators of tumorigenesis and tissue-specific metastasis. Proteomic profiling has identified Annexin A2 as one of the most highly expressed proteins in exosomes; however, studies focused on the biological role of exosomal-AnnexinA2 (exo-AnxA2) are still lacking. In this study, mechanistic insight was sought regarding exo-AnxA2 and its function in angiogenesis and breast cancer metastasis. Multiple in vitro and in vivo techniques were used to study the role of exo-AnxA2 in angiogenesis...

This review summarizes the most up-to-date approach to the multidisciplinary management of patients with breast cancer brain metastases. A brief overview of the epidemiology and biology of breast cancer brain metastasis is provided. The perspectives of radiation oncology, neurosurgery, and medical oncology-and landmark studies from each discipline-are all discussed. We also offer practical tips to help guide the treating physician, including data on antiseizure medications. Finally, we introduce the concept of a multidisciplinary clinic that combines input from medical and radiation oncology, neurosurgery, and support services, which we developed at the University of North Carolina as a coordinated and optimal approach to the management of patients with this complex disease...

BACKGROUND: Minimally-invasive approaches are attractive alternative to standard craniotomy for large intracranial tumors with potentially lesser morbidity. In this report, we describe a sequential combination of two minimally-invasive surgical techniques to treat a large intracranial tumor. CLINICAL PRESENTATION: A 49year-old woman presented with a history of breast cancer and large left parietal metastasis with significant perilesional edema. This was initially managed by whole brain radiation therapy and stereotactic radiosurgery...

Although drug resistance is often observed in metastatic recurrence of breast cancer, little is known about the intrinsic drug resistance in such metastases. In the present study, we found, for the first time, that MDA-MB-231BR, a brain metastatic variant of a human breast cancer cell line, was refractory to treatment with 5-fluorouracil (5-FU) even without chronic drug exposure, compared to its parent cell line, MDA-MB-231, and a bone metastatic variant, MDA-MB-231SCP2. Both the mRNA and protein levels of COX-2 and BCL2A1 in MDA-MB-231BR were significantly higher than those in MDA-MB-231 or MDA-MB-231SCP2...

Survival among patients with metastatic breast cancer may vary according to the site of metastasis and receptor status. We used Danish nationwide medical registries to establish a cohort of patients with metastatic breast cancer (870 with de novo metastatic disease and 3518 with recurrent disease with distant metastasis) diagnosed during 1997-2011. We examined 1-year and >1 to 5-year mortality associated with first site of metastasis and receptor expression status of the primary tumor. Cox proportional regression was used to compute confounder-adjusted mortality rate ratios (MRRs) associated with site of metastasis, stratified by receptor status...

The outcome of recurrent brain metastasis is dismal. This study aims to assess the clinical outcomes and toxicity of reirradiation as a salvage treatment for progressive brain metastasis in patients with advanced breast cancer. Between July 2005 and September 2014, the medical records of 56 patients with brain metastasis from breast cancer were retrospectively reviewed. Of these patients, 39 received whole-brain radiotherapy (WBRT) followed by stereotactic radiosurgery (SRS) reirradiation (Group 1), and 17 received SRS followed by WBRT reirradiation (Group 2)...

Radiation-induced nausea and vomiting (RINV) is one of the most distressing symptoms that adversely affects quality of life (QOL) as well as the ongoing management plan of cancer patients. Although there are protocols for management of chemotherapy induced nausea and vomiting (CINV) but such guidelines are still lacking for RINV. Various agents like 5-hydroxy tryptophan 3 (5-HT3) antagonist, dexamethasone, metoclopramide and haloperidol are used in clinical practice for RINV but the results are not very encouraging...

Breast cancer is the second-leading cause of metastatic disease in the central nervous system (CNS). Recent advances in the biological understanding of breast cancer have facilitated an unprecedented increase of survival in a subset of patients presenting with metastatic breast cancer. Patients with HER2 positive (HER2+) or triple negative breast cancer are at highest risk of developing CNS metastasis, and typically experience a poor prognosis despite treatment with local and systemic therapies. Among the obstacles ahead in the realm of developmental therapeutics for breast cancer CNS metastasis is the improvement of our knowledge on its biological nuances and on the interaction of the blood brain barrier with new compounds...

BACKGROUND: Triple-negative breast cancer (TNBC) lacks expression of steroid hormone receptors (estrogen receptor α and progesterone) and epidermal growth factor receptor type 2. This phenotype shows high metastatic potential, with particular predilection to lungs and brain. Determination of TNBC transcriptomic profiles associated with high risk of brain metastasis (BM) might identify patients requiring alternative, more aggressive, or specific preventive and therapeutic approaches. PATIENTS AND METHODS: Using a cDNA-mediated annealing, selection, extension, and ligation assay, we investigated expression of 29,369 gene transcripts in primary TNBC tumor samples from 119 patients-71 in discovery cohort A and 48 in independent cohort B-that included best discriminating genes...

PURPOSE: The purpose of this study was to evaluate the clinical status, prognostic factors and treatment modalities affecting survival in patients with brain metastasis. We aimed to evaluate the whole brain radiation therapy (WBRT) outcomes of patients with brain metastasis in our center. METHODS: Clinical data of 315 patients referred to our center between 2004 and 2014 with metastatic brain cancers were collected and analysed for possible relationships between survival time, age, gender, Karnofsky performance status (KPS), recursive partitioning analysis (RPA), primary tumor, number of brain lesions, surgery, radiation therapy scheme, extracranial metastatic status and primary disease control status...

Metastasis is the most common cause of mortality in breast cancer patients worldwide. To identify improved mouse models for breast cancer growth and spontaneous metastasis, we examined growth and metastasis of both estrogen receptor positive (T47D) and negative (MDA-MB-231, SUM1315, and CN34BrM) human breast cancer cells in nude and NSG mice. Both primary tumor growth and spontaneous metastases were increased in NSG mice compared to nude mice. In addition, a pattern of metastasis similar to that observed in human breast cancer patients (metastases to the lungs, liver, bones, brain, and lymph nodes) was found in NSG mice...

PURPOSE: Brain metastasis (BM) with a cystic component from breast cancer is rare and largely uncharacterized. The purpose of this study was to identify the characteristics of cystic BM in a large cohort of breast cancer patients. RESULTS: A total of 35 eligible patients with cystic BM and 255 patients with solid BM were analyzed. Three factors were significantly associated with an increased probability of developing cystic lesions: age at diagnosis ≤ 40 years, age at BM ≤ 45 years, and poor histological grade (p < 0...

The discovery of various driver pathways and targeted small molecule agents/antibodies have revolutionized the management of metastatic breast cancer. Currently, the major targets of clinical utility in breast cancer include the human epidermal growth factor receptor 2 (HER2) and epidermal growth factor receptor (EGFR), vascular endothelial growth factor (VEGF) receptor, mechanistic target of rapamycin (mTOR) pathway, and the cyclin-dependent kinase 4/6 (CDK-4/6) pathway. Brain metastasis, however, remains a thorn in the flesh, leading to morbidity, neuro-cognitive decline, and interruptions in the management of systemic disease...
