Breast cancer is the most common cancer in women and is the second most common cause of cancer-related death. Despite the relatively high prevalence of this disease, breast cancer manifestations in the head and neck are relatively rare. Supraclavicular lymphadenopathy and bony metastases to the mandible and maxilla are the most common manifestation of breast cancer in the head and neck. Head and neck metastases are the first presentation of distant disease in approximately one-third of cases. The prognosis of breast cancer with distant metastases to the head and neck is generally poor, and the management of these lesions is controversial...

MicroRNA is a class of noncoding RNAs able to base pair with complementary messenger RNA sequences, inhibiting their expression. These regulatory molecules play important roles in key cellular processes including cell proliferation, differentiation and response to DNA damage; changes in miRNA expression are a common feature of human cancers. To gain insights into the mechanisms involved in breast cancer progression we conducted a microRNA global expression analysis on a 21T series of cell lines obtained from the same patient during different stages of breast cancer progression...

Background: Possible targeted therapies for metastatic triple negative breast cancer (TNBC) include cytotoxic chemotherapy that causes interstrand breaks (platinum-based drugs). The excision repair cross-complementation 1 (ERCC1) enzyme plays an essential role in the nucleotide excision repair pathway, removing platinum-induced DNA adducts and contributing to cisplatin resistance. Detecting ERCC1 overexpression is important in considering treatment options for metastatic TNBC, including individualized approaches to therapy, and may facilitate improved responses or reduction of unnecessary toxicity...

Breast cancer metastases cause significant patient mortality. During metastases, cancer cells use autophagy, a catabolic process to recycle nutrients via lysosomal degradation, to overcome nutritional stress for their survival. The Runt-related transcription factor, Runx2, promotes cell survival under metabolic stress and regulates breast cancer progression and bone metastases. Here, we identify that Runx2 enhances autophagy in metastatic breast cancer cells. We defined Runx2 function in cellular autophagy by monitoring microtubule-associated protein light chain (LC3B-II) levels, an autophagy-specific marker...

The appearance of meningeal carcinomatosis in breast cancer is an event that is being reported increasingly more frequently in the literature. It seems to be related with the lengthening of the patients' lives, improved sensitivity to diagnostic imaging and impermeability of the blood-brain barrier to the chemotherapeutic agents. It is an evolutionary form that affirms the metastatic invasion of the subarachnoidal space and is correlated with limited survival. Its diagnosis is difficult, due to the lack of specificity of the clinical signs dominated by headaches, cognitive disorders and possible signs and symptoms of progressive focal lesions...

Curcumol, a major volatile component in Rhizoma Curcumae, exhibited potent anti-metastatic effect on breast cancer cells. However, its molecular mechanism remains poorly understood. In this study, we employed a 2-DE based proteomics to investigate the cellular targets of curcumol in MDA-MB-231 cells, and identified 10 differentially expressed proteins. Moreover, Gene Ontology analysis revealed that those proteins mainly get involved in 9 types of cellular components, 7 different biological processes and 9 kinds of molecular functions, and 35 pathways (p < 0...

Jürgen Dittmer
Breast cancer is a systemic disease characterized by early dissemination of tumor cells to distant organs. In this foreign environment, tumor cells may stay in a dormant state as single cells or as micrometastases for many years before growing out into a macrometastatic lesion. As metastasis is the primary cause for breast cancer-related death, it is important to understand the mechanisms underlying the maintenance of dormancy and dormancy escape to find druggable targets to eradicate metastatic tumor cells...

Based on the prominent role estrogen receptor (ER) plays in breast cancer, endocrine therapy has been developed to block the ER pathway and has shown great effectiveness. Fulvestrant, the first selective ER down-regulator (SERD), was demonstrated to completely suppress ERα and notably efficient. However, resistance to fulvestrant occurs, either intrinsic or acquired during the treatment. Several potential mechanisms inducing fulvestrant resistance have been proposed, composed of activated ERα-independent compensatory growth factor signaling, stimulated downstream kinases, altered cell cycle mediators etcetera...

BACKGROUND: The mechanisms of breast cancer collective invasion are poorly understood limiting the metastasis therapy. The ATPase RUVBL1 is frequently overexpressed in various cancers and plays a crucial role in oncogenic process. We further investigated the role of RUVBL1 in promoting collective invasion and uncovered that targeting RUVBL1 could inhibit metastatic progression. METHODS: The expression levels of RUVBL1 and ITFG1 were examined by Western blot and qRT-PCR...

Central nervous system metastases have been reported in 15-25% of breast cancer patients, and the incidence is increasing. Moreover, the survival of these patients is generally poor, with reports of a 1-year survival rate of 20%. Therefore, a better knowledge about the determinants of brain metastasization is essential for the improvement of the clinical outcomes. Here, we summarize the current data about the metastatic cascade, ranging from the output of cancer cells from the primary tumour to their colonization in the brain, which involves the epithelial-mesenchymal transition, invasion of mammary tissue, intravasation into circulation, and homing into and extravasation towards the brain...

To date, high mortality in women due to malignancy breast cancer related to the metastasis to the bone is a significant challenge. Since, magnetic nanoparticles (MNPs) conjugated with the biocompatible polymers was employed for the delivery of some hydrophobic anti-cancer agents, so the main aim of the current research was to assess whether cisplatin-loaded MNPs enhanced the anti-cancer effect of free cisplatin in breast cancer cells.MNPs decorated with PEG were synthesized by an improved co-precipitation technique, and then cisplatin was loaded onto the MNPs via a simple mixing method...

Pathological status of lymph nodes (LNs) plays a critical role in staging and treatment for the patients with breast cancer. Sentinel lymph node biopsy has become the standard method in determining pathological status of axillary LNs. Therefore, the determination of sentinel lymph nodes (SLNs) and therapy of metastatic LNs are highly desirable in clinic. Herein, an unprecedented carbon nanoparticles (CNs)-incorporated liquid-gas phase-transition nanodroplets (CNPs) with strong near-infrared (NIR) absorption, good biocompatibility, excellent photoacoustic (PA) and ultrasound (US) contrast, and high photothermal-conversion efficiency are reported in this study...

Whether circulating tumor cells (CTCs) can be used as an indicator of treatment response in breast cancer (BC) needs to be clarified. We addressed this issue by a meta-analysis. PubMed, EMBase and Cochrane library databases were searched in June 2016. Effect measures were estimated as pooled risk ratio (RR), odds ratio (OR) or mean difference by fixed- or random-effect models, according to heterogeneity of included studies. In total, 50 studies with 6712 patients were recruited. Overall analysis showed that there was a significant reduction of CTC-positive rate (RR = 0...

MicroRNA (miRNA) expression has been linked to the molecular pathogenesis of hepatocellular carcinoma (HCC). The aberrant expression of miRNA is involved in the processes of tumorigenesis and cancer progression. According to the latest research, miR-888-5p is associated with strong cancer-promoting effect. For instance, miR-888-5p is up-regulated in prostate cancer and breast cancer. Nevertheless, the role of miR-888-5p in HCC has not been investigated to date. In this study, we found that miR-888-5p levels in four HCC cell lines (SMMC7721, HepG2, Huh-7 and Bel7402) were significantly up-regulated compared with human hepatocyte cell line (HHL-5)...

Over the past 15 years, targeted therapy has revolutionized the systemic treatment of cancer. In parallel, there has been a growing debate on the choice of end points in clinical trials in oncology. This debate basically hinges on the choice between overall survival (OS) and progression-free survival (PFS). PFS is advantageous because it is measured earlier than OS, requires a smaller sample size than OS to achieve the desired power, and is not influenced by cross-over. On the other hand, PFS is prone to measurement error and bias, and may not capture the entire treatment effect on the outcomes of most interest to patients with an incurable disease: a prolonged survival and improved quality of life...
