Breast cancer frequency in human and other mammal female populations has worryingly increased lately. The acute necessity for taxonomy of the aetiological factors along with seeking for new diagnostic tools and therapy procedures aimed at reducing mortality have yielded in an intense research effort worldwide. Surgery is a regular method to counteract extensive development of breast cancer and prevent metastases provided that negative surgical margins are achieved. This highly technical challenge requires fast, extremely sensitive and selective discrimination between malignant and benign tissues even down to molecular level...

BACKGROUND: Breast cancer is the most common solid tumor to cause cutaneous metastases. These are incurable and the treatment goal is geared toward local control with surgical excision, radiation, and chemotherapy. However, treatment can be challenging in subjects with end-stage liver disease and a multidisciplinary approach is warranted. CASE REPORT: In this case report, we present a 61-year-old female with primary biliary cirrhosis and human epidermal growth factor-2 (HER-2)-positive breast cancer, who subsequently developed cutaneous metastases...

Metastatic breast cancer (MBC) entails an overall 5-year survival of approximately 25%. The choice of therapy is influenced by expression of the HER2 gene and hormone receptors, by a disease-free interval, and by age. The use of paclitaxel combined with gemcitabine (doublet protocol) has shown efficacy as first-line treatment for MBC in either initial or maintenance therapy when compared to monotherapy with paclitaxel. There is evidence showing that the doublet protocol is a good alternative to maintenance therapy in women under 50 years old...

The MMTV-PyMT transgenic mouse model is commonly used to study luminal B subtype, which has a lower prevalence but a worse prognosis than luminal A subtype among patients with breast cancer. The objective of the present study was to determine whether an obesogenic, high-fat diet enhances primary tumorigenesis and pulmonary metastasis in female MMTV-PyMT mice. The high-fat diet slightly but significantly increased caloric intake and body fat mass compared to the AIN93G diet. The high-fat diet significantly increased primary mammary tumor progression by 59%, primary tumor weight by 60%, and the number of lung metastases by 147%...

AIM: Triple-negative breast cancer (TNBC), defined by the absence of receptors for estrogen, progesterone and human epithelial receptor 2 (HER2), is a recalcitrant disease in need of effective therapy. We previously isolated very-highly metastatic variants of the TNBC cell line MDA-MB-231 using serial orthotopic implantation of MDA-MB-231 human breast cancer cells in nude mice. MATERIALS AND METHODS: MDA-MB-231 cells expressing red fluorescent protein (MDA-MB-231-RFP) (1×10(7) cells/site) were initially injected subcutaneously in the flank of nude mice...

BACKGROUND: Most primary and metastatic bone tumors demonstrate increased osteoclast activity and bone resorption. Current treatment is based on a combination of surgery, radiotherapy and chemotherapy. Severe side effects are associated with chemotherapy due to use of high dosage and nonspecific uptake. Bisphosphonates have a strong affinity to Ca(2+) ions and are widely used in the treatment of bone disorders. RESULTS: We have engineered a unique biodegradable bisphosphonate nanoparticle (NPs) bearing two functional surface groups: (1) primary amine groups for covalent attachment of a dye/drug (e...

The development of metastases largely relies on the capacity of cancer cells to invade extracellular matrices (ECM) using two invasion modes termed 'mesenchymal' and 'amoeboid', with possible transitions between these modes. Here we show that the SCN4B gene, encoding for the β4 protein, initially characterized as an auxiliary subunit of voltage-gated sodium channels (NaV) in excitable tissues, is expressed in normal epithelial cells and that reduced β4 protein levels in breast cancer biopsies correlate with high-grade primary and metastatic tumours...

PURPOSE: Administration of 5 million alloreactive natural killer (NK) cells after low-dose chemo-irradiation cured mice of 4T1 breast cancer, supposedly dose dependent. We now explored the efficacy of bone marrow as alternative in vivo source of NK cells for anti-breast cancer treatment, as methods for in vitro clinical scale NK cell expansion are still in developmental phases. METHODS: Progression-free survival (PFS) after treatment with different doses of spleen-derived alloreactive NK cells to 4T1-bearing Balb/c mice was measured to determine a dose-response relation...

PURPOSE: The majority of breast cancer patients receive endocrine therapy, including aromatase inhibitors known to cause increased bone resorption. Bone-related biomarkers at the time of breast cancer diagnosis may predict future risk of osteoporosis and fracture after endocrine therapy. METHODS: In a large population of 2,401 female breast cancer patients who later underwent endocrine therapy, we measured two bone remodeling biomarkers, TRAP5b and BAP, and two bone regulating biomarkers, RANKL and OPG, in serum samples collected at the time of breast cancer diagnosis...

PURPOSE: TNM classification of solitary internal mammary lymph node metastases (IMLNMs) in breast cancer varies depending on their method of detection: sentinel lymph node biopsy (pN1b) or clinical examination including radiological and/or physical examination (pN2b). This study aimed to evaluate whether there is a difference in prognosis between both groups. METHODS: Data of all patients diagnosed with primary invasive epithelial breast cancer between 2005 and 2008 were obtained from the Netherlands Cancer Registry...

Carcinomatous lymphangitis accounts for 5% of all skin metastases, but blue lymphangitis of the breast has never been described. We report a case of blue lymphangitis of the breast in a patient 11 years after treatment for ipsilateral breast cancer that was in full remission. Breast examination and imaging showed no other abnormalities. Skin biopsy revealed a carcinomatous-pigmented infiltration corresponding to melanoma metastasis, which helped highlight a primitive right flank injury. This case report emphasizes that a full body exam should always be performed with unusual presentation of breast cancer and reiterates the indispensable place of histology before any diagnosis...

OBJECTIVE The neurological prognostic score (NPS) was recently proposed as a means for predicting neurological outcomes, such as the preservation of neurological function and the prevention of neurological death, in brain metastasis patients treated with Gamma Knife radiosurgery (GKRS). NPS consists of 2 groups: Group A patients were expected to have better neurological outcomes, and Group B patients were expected to have poorer outcomes. NPS robustness was tested in various situations. METHODS In total, 3040 patients with brain metastases that were treated with GKRS were analyzed...

OBJECTIVE The median postoperative survival duration of patients with brain metastases who undergo tumor resection is 12 months. Most of these patients die of systemic metastases or the progression of primary cancer but not brain metastases. The criteria for indicating resection are still controversial. Systemic assessment is restricted, especially in patients who need emergent management for their large-size or life-threatening brain metastases. The neutrophil-to-lymphocyte ratio (NLR) is reported to correlate with survival time or progression-free survival in patients with various cancers...

Topotecan (TPT), a potent anticancer camptothecin analog, is well described for the treatment of ovarian cancer, but has also anticancer activity against small-cell and non-small-cell lung cancer, breast cancer, and acute leukemia. Various nanocarriers, including liposomes, have been exploited for targeted delivery of TPT. However, there are a number of challenges with TPT delivery using TPT liposomes (TLs), such as low encapsulation efficiency, physiological pH labile E ring (hydrolysis), accelerated blood clearance, multidrug resistance, and cancer metastases...

The occurrence of bone metastases is common in patients with advanced cancer. Metastatic bone disease occurs across a range of tumor types, with prostate and breast cancers having the highest incidence. Bone metastases, and associated skeletal-related events, are the most common cause of cancer-related pain. This article is protected by copyright. All rights reserved.

BACKGROUND: Certain studies suggest that using indocyanine green (ICG) could be comparable with using radioisotopes (RI) in detecting sentinel lymph nodes (SLNs) in breast cancer. A number of these studies were performed in Asia. The objective of our pilot study was to evaluate within a European population of breast cancer patients the detection rate of SLNs using ICG and the HyperEye system and the concordance in SLNs detected using this method and the standard method involving RI and a gamma probe...

Drug resistance has been one of the major obstacles limiting the success of cancer chemotherapy. In two thirds of breast cancer patients, large (>1cm) residual tumors are present after neoadjuvant chemotherapy (NCT). The residual tumor and involved nodes have been indicators of relapse and survival very important in breast cancer. The goal of this preliminary study was to assess the predictive significance of a panel of molecular biomarkers, related with the response to treatment or drug resistance to NCT, as determined on the diagnostic tumor...

BACKGROUND: Brain cancer from metastasized breast cancer has a high mortality rate in women. The treatment of lesions is hampered in large part by the blood-brain barrier (BBB), which prevents adequate distribution of anti-cancer compounds to brain metastases. METHOD: In this study we used a novel screening method to identify candidate molecules that are well-suited to utilizing the BBB choline transporter for distribution into the brain parenchyma. RESULTS: From our screen we identified two compounds, Ch-1 and Ch-2 that were able to reduce the brain tumor burden in a murine mouse model of brain metastasis of breast cancer...
