BACKGROUND: Breast cancer is a notable cause of cancer-related death in women worldwide. Metastasis to distant organs is responsible for ~90% of this death. Breast cells convert to malignant cancer cells after acquiring the capacity of invasion/intravasation into surrounding tissues and, finally, extravasation/metastasis to distant organs (i.e., lymph nodes, lungs, bone, brain). Metastasis to distant organs depends on interactions between disseminated tumor cells (DTCs) and the endothelium of blood vessels present in the tumor microenvironment...

PURPOSE: Radiotherapy plays a major role in relieving pain caused by bone metastases; paradoxically initial flare of symptom is common. Our objectives were to assess prospectively the incidence, and to identify predictor's factors of this acute complication. PATIENT AND METHODS: Forty-one patients treated with analgesic external beam radiotherapy were followed prospectively. Patients recorded pain severity and analgesic intake was documented. Pain flare was defined as an increase of two points in the intensity of pain on the numerical scale with no reduction in analgesic intake and/or 25% increase of the analgesic intake without decreasing pain intensity...

Background: Breast cancer bone metastasis (BCBM)-specific genes have been reported without considering biological differences based on estrogen receptor (ER) status. The aims of this study were to identify BCBM-specific genes using our patient dataset and validate previously reported BCBM-specific genes, and to determine whether ER-status-related biological differences matter in identification of BCBM-specific genes. Methods: We used Affymetrix GeneChips to analyze 365 primary human epidermal growth factor receptor 2 (HER2)-negative invasive breast cancer specimens...

Nephronectin (NPNT), a highly conserved extracellular matrix protein, plays an important role in regulating cell adhesion, differentiation, spreading and survival. NPNT protein belongs to epidermal growth factor (EGF)-like superfamily and exhibits several common structural determinants; including EGF-like repeat domains, MAM domain (Meprin, A5 Protein, and Receptor Protein-Tyrosine Phosphatase µ), RGD motif (Arg-Gly-Asp) and a coiled-coil domain. It regulates integrins-mediated signaling pathways via the interaction of its RGD motif with integrin α8β1...

It is known that V-ATPases (vacuolar H+-ATPase) are involved in breast cancer growth and metastasis. Part of this action is similar to their role in osteoclasts, where they're involved in extracellular acidification and matrix destruction; however, the roles of their subunits in cancer cell proliferation, signaling, and other pro-tumor actions are not well established. Analysis of TCGA data shows that V-ATPase subunit Atp6v1c1 is overexpressed or amplified in 34% of human breast cancer cases, with a 2-fold decrease in survival at 12 years...

Breast cancer is a leading cause of cancer death in women, with the majority of these deaths caused by metastasis to distant organs. The most common site of breast cancer metastasis is the bone, which has been shown to provide a rich microenvironment that supports the migration and growth of breast cancer cells. Additionally, growing evidence suggests that breast cancer cells that do successfully metastasize have a stem-like phenotype including high activity of aldehyde dehydrogenase (ALDH) and/or a CD44+CD24- phenotype...

Serum from one hundred and ten breast cancer patients and thirty healthy female volunteers, were prospectively collected and evaluated for serum levels of Shh and IL-6 using human Shh and IL-6 specific enzyme-linked immunoassays. All patients were regularly monitored for event free survival (EFS) and overall survival (OS). Overall outcome analysis was based on serum Shh and IL-6 levels. In patients with progressive metastatic BC, both serum Shh and IL-6 concentrations were elevated in 44% (29 of 65) and 63% (41 of 65) of patients, respectively, at a statistically significant level [Shh (p = 0...

BACKGROUND: Metastasis of breast cancer displays site-specificity towards bone. Recently, studies have emerged indicating that primary tumors may remotely influence creation of a pre-metastatic niche. In this study, we used human fetal osteoblastic cells and MDA-MET, a metastatic and preferentially bone homing derivative of the breast cancer cell line MDA-MB-231. We examined 1) whether secreted factors from MDA-MET cells increase generation of chemoattractants by human foetal osteoblastic cells 2) whether MDA-MET cells were responsive to these chemoattractants and 3) the identity of these chemoattractants...

A high proportion of patients with breast cancer develop bone metastases, yet data on routine treatment with bone-targeted agents (BTA) are rare. We report real-life outcome data of patients with breast cancer metastasised to the bone treated by office-based oncologists in Germany. The ongoing, prospective, multicentre, population-based cohort study Tumour Registry Breast Cancer (TMK) was started in 2007 in 140 centres across Germany. This interim analysis of 1094 patients with bone metastases revealed differences among the tumour subtypes: at start of first-line therapy, 36% of the patients with hormone receptor (HR)-positive and only 20% of the patients with HR-negative tumours presented with bone-only metastasis...

Common sites for metastatic spreading from breast cancer are bones, lungs and liver, the skeletal muscle being an unusual site. Although rare, when skeletal muscle metastases occur they are associated with a poor prognosis. These metastases are clinically difficult to diagnose since they can be found without pain symptoms. Radiologically, magnetic resonance imaging has been considered better than computed tomography for imaging of the muscles and has been the first procedure to use in case of muscle metastasis suspicion...

BACKGROUND/AIM: Evidence shows that Luminal A breast cancer is likely to undergo bone metastasis, but the mechanisms involved remain unknown. This study's aim was to demonstrate a correlation between estrogen receptor (ER) positivity and bone metastasis as the clinically preferred site of metastasis, as well as investigating the role of ERα-Src signaling in MCF-7 cells using Snail over-expression as an in vivo bone metastasis model. METHODS: Clinically, the records of breast cancer with distant metastasis were retrospectively reviewed to correlate breast cancer subtypes and preferential metastatic sites...

Bone is an especially prone metastatic site for breast cancer, and to block the vicious cycle between bone resorption and tumor growth is an important strategy for the treatment of breast cancer bone metastasis. In this paper, pH- and redox-sensitive as well as breast cancer bone metastasis-targeting nanoparticles (DOX@ALN-(HA-PASP)CL) were prepared, and also their anti-tumor activity and anti-bone resorption effect were investigated in detail. The in vitro experimental results indicated that DOX released from DOX@ALN-(HA-PASP)CL exhibited a GSH-, DTT- and pH-dependent manner...

INTRODUCTION: Patients with a history of chemotherapy or stem cell transplantation (SCT) and prolonged neutropenia are at risk for hepatic and/or splenic seeding of Candida. In our experience, hepatosplenic candidiasis (HSC) without documented candidemia often remains unrecognized. CASE PRESENTATIONS: We describe three cases of HSC without documented candidemia and the challenges in establishing the diagnosis and adequately treating this condition. The first patient had a history of SCT for treatment of breast cancer and was scheduled for hemihepatectomy for suspected liver metastasis...

Cancer-induced bone pain (CIBP) is common in patients with bone metastases (BM), significantly impairing quality of life. The current treatments for CIBP are limited since they are often ineffective. Local acidosis derived from glycolytic carcinoma and tumor-induced osteolysis is only barely explored cause of pain. We found that breast carcinoma cells that prefer bone as a metastatic site have very high extracellular proton efflux and expression of pumps/ion transporters associated with acid-base balance (MCT4, CA9, and V-ATPase)...

OBJECTIVE: Wernicke encephalopathy (WE) is a neuropsychiatric disorder caused by thiamine deficiency. Several reports of WE in cancer patients are known. WE is sometimes overlooked because most patients do not exhibit its typical symptoms (e.g., delirium, ataxia, ocular palsy). If delirium is not present, a diagnosis of WE is difficult because delirium is the hallmark symptom of WE. METHOD: Taken from a series on WE in cancer, we report two patients who developed WE without delirium during periodic psycho-oncology outpatient visits...

Previous reports have documented that cholesterol-lowering simvastatin prevented osteolytic metastasis of breast cancer in animal model in which cancer cells were placed into blood circulation. Thus, simvastatin treatment might have a preventive effect in inhibiting osteoclast activity of metastatic bone microenvironment. This study documented that both simvastatin and MBCD (cholesterol depleting drug) blocked the breast cancer-induced TRAP and MMP activity, and expressions of various osteoclastogenic genes (TRAP, Cathepsin K, and NFATc1) in pre-osteoclast RAW264...
