Breast cancer is the most common cause of skin metastases in women. The probability of their occurrence ranges from about 5% in the entire population to as much as 30% in the late stages of the disease. Although rarely life-threatening, they have a major impact on the quality of life of patients with this diagnosis, being the cause of pain, effusion, ulceration, infection, and psychological discomfort. Available methods of treatment, both local and systemic, often fail to provide adequate control of the disease...

Molecular drivers underlying bone metastases in human cancer are not well understood, in part due to constraints in bone tissue sampling. Here, RNA sequencing (RNA-seq) was performed of circulating tumor cells (CTCs) isolated from blood samples of women with metastatic estrogen receptor (ER)+ breast cancer, comparing cases with progression in bone versus visceral organs. Among the activated cellular pathways in CTCs from bone-predominant breast cancer is androgen receptor (AR) signaling. AR gene expression is evident, as is its constitutively active splice variant AR-v7...

Brain metastases (BM) occur in 20-40% of patients with cancer and 60-75% of patients with BM become symptomatic. Due to an aging population and advances in the treatment of primary cancers, patients are living longer and are more likely to experience complications from BM. The diagnosis of BM drastically worsens long-term survival rates, with multiple metastases being a poor prognostic factor. Until recently, the mainstay of treatment consisted of stereotactic radiosurgery (SRS), surgical resection, whole brain radiation therapy (WBRT), or a combination of these modalities...

Signal transducer and activator of transcription 3 (STAT3), glioma oncogene homolog 1 (GLI1), and truncated GLI1 (tGLI1) are oncogenic transcription factors playing important roles in breast cancer. tGLI1 is a gain-of-function GLI1 isoform. Whether STAT3 physically and/or functionally interacts with GLI1/tGLI1 has not been explored. To address this knowledge gap, we analyzed 47 node-positive breast cancer specimens using immunohistochemical staining and found that phosphorylated-STAT3 (Y705), GLI1, and tGLI1 are co-overexpressed in the majority of triple-negative breast carcinomas (64%) and HER2-enriched (68%) breast carcinomas, and in lymph node metastases (65%)...

Metaplastic breast carcinoma (MBC) is rare and has a poor prognosis. Here we describe genetic analysis of a 41-year-old female patient with MBC and neurofibromatosis type I (NF1). She initially presented with pT3N1a, grade 3 MBC, but lung metastases were discovered subsequently. To identify the molecular cause of her NF1, we screened for germline mutations disrupting NF1 or SPRED1, revealing a heterozygous germline single nucleotide variant (SNV) in exon 21 of NF1 at c.2709G>A, chr17: 29556342. By report, this variant disrupts pre-mRNA splicing of NF1 transcripts...

BACKGROUND: Approximately 1% of patients with ductal carcinoma in situ (DCIS) will die of breast cancer within 10 years. Women who develop an invasive breast cancer after DCIS have a much greater risk of dying than those who do not and it is often stated that these deaths are a consequence of metastases from the invasive in-breast recurrence. This progression is the result of a two-step process: first local invasive recurrence and then spread beyond the breast. A large proportion of women who die of DCIS have no record of invasive recurrence...

The presence and extent of axillary nodal metastases at the time of breast cancer diagnosis is a critical factor in disease prognosis and plays a central role in deciding the best treatment for patients. Accurate assessment of the axilla is therefore an essential component in staging breast cancer. Over the years, axillary staging has evolved from surgical axillary lymph node dissection (ALND), with its numerous associated long-term complications, to the much less-radical surgical sentinel lymph node excision biopsy (SLNB), the current reference standard...

The brain is the most common site of first metastasis for patients with HER2-positive breast cancer treated with HER2-targeting drugs. However, the development of effective therapies for breast cancer brain metastases (BCBMs) is limited by an incomplete understanding of the mechanisms governing drug sensitivity in the central nervous system. Pharmacodynamic data from patients and in vivo models suggest that inadequate drug penetration across the 'blood-tumor' barrier is not the whole story. Using HER2-positive breast cancer brain metastases as a case study, we highlight recent data from orthotopic brain metastasis models that implicates brain-specific drug resistance mechanisms in BCBMs and suggests a translational research paradigm to guide drug development for treatment of BCBMs...

The main problem in breast cancer treatment is the recurrence of tumor growth and metastases. Previous studies have suggested that Paclitaxel is widely used to treat various cancers. The present study analyzed the potential signaling pathway of Paclitaxel-inhibited breast cancer metastasis. It was demonstrated that Paclitaxel treatment significantly inhibited growth of breast cancer cell lines including MCF-7 and SKBR3 cells. Results demonstrated that Paclitaxel significantly inhibited breast cancer cell migration and invasion...

BACKGROUND: Tumor heterogeneity in breast cancer tumors is today widely recognized. Most of the available knowledge in genetic variation however, relates to the primary tumor while metastatic lesions are much less studied. Many studies have revealed marked alterations of standard prognostic and predictive factors during tumor progression. Characterization of paired primary- and metastatic tissues should therefore be fundamental in order to understand mechanisms of tumor progression, clonal relationship to tumor evolution as well as the therapeutic aspects of systemic disease...

Brain metastases natural history from one primary tumor type might be accelerated or favored by using certain systemic chemotherapy. A great deal was described in mice and suggested in human with antiangiogenic drugs, but little is known about the metastatic progression generated by the perverse effect of anticancer drugs. A total of 413 patients who underwent treatment for brain metastasis (2013-2016) were included. The identification of all previous anticancer drugs received by patients from primary tumor diagnosis to brain metastases diagnosis was collated...

The present study was undertaken to investigate the expression of prostate-specific membrane antigen (PSMA) in normal breast tissues, in cancerous breast tissues and in distant metastases from patients with breast cancer. Immunohistochemical analysis was performed to determine PSMA expression and angiogenic activity using anti-PSMA mAb and anti-CD31 mAb respectively. Immunofluorescence staining was applied to confirm the exact co-localization of PSMA and CD31. We observed different patterns of PSMA expression between normal and cancerous tissues...

Disseminated carcinomatosis of the bone marrow (DCBM) is characterized by diffuse infiltrative growth of tumor cells in the bone marrow and is associated with systemic hematological disorders. Bone marrow metastases from breast cancer are not rare, and they may lead to serious life-threatening conditions when there is an associated hematological disorder. Therefore, DCBM necessitates a definitive diagnosis and prompt systemic therapy. We herein present 4 such cases and a review of the previous relevant literature...

Breast cancer is the most common female cancer with considerable metastatic potential, explaining the need for new candidates that inhibit tumor metastasis. In our study, betulinic acid (BA), a kind of pentacyclic triterpenoid compound derived from birch trees, was evaluated for its anti-metastasis activity in vitro and in vivo. BA decreased the viability of three breast cancer cell lines and markedly impaired cell migration and invasion. In addition, BA could inhibit the activation of stat3 and FAK which resulted in a reduction of matrix metalloproteinases (MMPs), and increase of the MMPs inhibitor (TIMP-2) expression...

OBJECTIVES: Triple-negative breast cancers (TNBC) is an aggressive disease and often associated with early distant metastases, which negate the role of adjuvant radiotherapy. We studied the clinical utility of programmed death ligand-1 (PD-L1) and other available factors in predicting clinical outcome in TNBC. METHODS: Of the 539 patients with newly diagnosed TNBC between 2004 and 2011, we analyzed 117 patients who had both tumor samples which PD-L1 protein expression could be evaluated using immunohistochemistry and initial staging F-fluorodeoxyglucose (FDG) positron emission tomography (PET) data to find available immunologic or metabolic factors...
