Phenotypical change in metastatic breast carcinoma has widely been accepted as an inherent biological feature rather than technical fault. We analyzed the immunohistochemical phenotype and histopathological features of 25 primary breast carcinomas and 90 corresponding distant metastases in 23 organs retrospectively. Histological slides were reviewed for prognostic and predictive factors. Overall, metastases were more similar to each other and often differed from the primary tumor. We created a 3-step grouping system based on the localization of metastases...

Pituitary adenomas with sphenoid sinus or clivus invasion are not uncommon, but the pathogenesis responsible for this phenomenon remains unclear. Cathepsin K, expressed predominantly in osteoclasts, can degrade type I collagen and plays an essential role in bone resorption. Recent studies reported the expression of Cathepsin K in various malignant tumors, such as bone, breast, lung and prostate cancers, and its expression is further increased in bone metastasis or invasive subpopulations. In addition, cathepsin K inhibitors (CatKi) were demonstrated to effectively prevent or reduce osteolytic lesions in breast cancers with bone metastasis...

Bone metastases cause significant morbidity and mortality in late-stage breast cancer patients and are currently considered incurable. Investigators rely on translational models to better understand the pathogenesis of skeletal complications of malignancy in order to identify therapeutic targets that may ultimately prevent and treat solid tumor metastasis to bone. Many experimental models of breast cancer bone metastases are in use today, each with its own caveats. In this methods review, we characterize the bone phenotype of commonly utilized human- and murine-derived breast cell lines that elicit osteoblastic and/or osteolytic destruction of bone in mice and report methods for optimizing tumor-take in murine models of bone metastasis...

Frizzled receptors mediate Wnt ligands' signalling, which is crucially involved in regulating tissue development, differentiation and is often deregulated in cancer. In this study we found that the Wnt receptor frizzled 6 (FZD6) is frequently amplified in breast cancer, with an increased incidence in the triple negative breast cancer (TNBC) subtype. Ablation of FZD6 gene expression in mammary cancer cell lines: a) inhibited motility and invasion b) induced a more symmetric shape of organoid 3D cultures c) inhibited bone and liver metastasis in vivo...

Noninvasive multimodal imaging of tumor blood vessels allows the qualitative and quantitative assessment of morphological, functional, and molecular features of tumor angiogenesis longitudinally in a living organism. In this chapter we focus on the application of magnetic resonance imaging (MRI), computed tomography (CT), ultrasound (US), and positron emission tomography (PET) in tumor blood vessel visualization on the example of breast cancer bone metastasis in a nude rat model. Thereby, materials and methods are described that are needed to obtain complementary data on tumor vascularization from these imaging techniques...

: It has been proposed that bisphosphonates cause osteonecrosis of the jaws through impairment of the monocyte population function and proliferation. Such changes have been confirmed in jaw tissues, ex vivo. In this clinical study, we report for the first time a similar pattern of changes in peripheral blood monocytes. INTRODUCTION: The aim of this study is to examine the effect of zolendronic acid administration in the peripheral blood white cell population, seeking a plausible pathophysiological link between bisphosphonates and osteonecrosis of the jaw...

Distant metastases are relatively common in breast cancer, but spread to the head and neck region is uncommon and can be diagnostically challenging. Pathology databases of two academic hospitals were searched for patients. The diagnoses were by morphologic comparison with the primary breast specimen (when available) or through the use of immunohistochemical stains characteristic of breast carcinoma (cytokeratin 7, mammaglobin, GCDFP15, and/or GATA3 positive-excluding new primary tumors at the respective head and neck sites)...

Lethal progression of prostate cancer metastasis can be improved by developing animal models that recapitulate the clinical conditions. We report here that cytokeratin 13 (KRT13), an intermediate filament protein, plays a directive role in prostate cancer bone, brain, and soft tissue metastases. KRT13 expression was elevated in bone, brain, and soft tissue metastatic prostate cancer cell lines and in primary and metastatic clinical prostate, lung, and breast cancer specimens. When KRT13 expression was determined at a single cell level in primary tumor tissues of 44 prostate cancer cases, KRT13 level predicted bone metastasis and the overall survival of prostate cancer patients...

Bone is one of the most common organs of breast cancer metastasis. Cancer cells that mimic osteoblasts by expressing bone matrix proteins and factors have a higher likelihood of metastasizing to bone. However, the molecular mechanisms of osteomimicry formation of cancer cells remain undefined. Herein, we identified a set of bone-related genes (BRGs) that are ectopically co-expressed in primary breast cancer tissues and determined that osteomimetic feature is obtained due to the osteoblast-like transformation of epithelial breast cancer cells that have undergone epithelial-mesenchymal transition (EMT) followed by bone morphogenetic protein-2 (BMP2) stimulation...

Aromatase inhibitors (AIs) are the first-line recommended standard of care for postmenopausal estrogen receptor-positive breast cancer. Because they cause a profound suppression of estrogen levels, concerns regarding their potential to increase the risk of fracture were rapidly raised. There is currently a general consensus that a careful baseline evaluation is needed of the risk of fracture in postmenopausal women about to start treatment with AIs but also in all premenopausal women with early disease. Bisphosphonates have been shown in several phase III trials to prevent the bone loss induced by cancer treatment, although no fracture data are available...

Liver metastases remain a major barrier to successful management of malignant disease, particularly for cancers of the gastrointestinal tract but also for other malignancies, such as breast carcinoma and melanoma. The ability of metastatic cells to survive and proliferate in the liver is determined by the outcome of complex, reciprocal interactions between tumor cells and different local resident subpopulations, including the sinusoidal endothelium, stellate, Kupffer, and inflammatory cells that are mediated through cell-cell and cell-extracellular matrix adhesion and the release of soluble factors...

BACKGROUND: Bone metastasis is a single condition but presents with various patterns and severities. Skeletal- related events (SREs) deteriorate overall performance status and reduce quality of life. However, guidelines for early detection and management are limited. This study includes a survey of the prevalence of bone metastasis in cases with common cancers in Thailand as well as a focus on survival patterns and SREs. MATERIALS AND METHODS: A retrospective cohort analysis was conducted using a database of the Chiang Mai Cancer Registry and the Musculoskeletal Tumor Registry of the OLARN Center, Chiang Mai University...

The normal developmental program that prolactin generates in the mammary gland is usurped in the cancerous process and can be used out of its normal cellular context at a site of secondary metastasis. Prolactin is a pleiotropic peptide hormone and cytokine that is secreted from the pituitary gland, as well as from normal and cancerous breast cells. Experimental and epidemiologic data suggest that prolactin is associated with mammary gland development, and also the increased risk of breast tumors and metastatic disease in postmenopausal women...

Bone metastases are a common complication of epithelial cancers, of which breast, prostate and lung carcinomas are the most common. The establishment of cancer cells to distant sites such as the bone microenvironment requires multiple steps. Tumour cells can acquire properties to allow epithelial-to-mesenchymal transition, extravasation and migration. Within the bone metastatic niche, disseminated tumour cells may enter a dormancy stage or proliferate to adapt and survive, interacting with bone cells such as hematopoietic stem cells, osteoblasts and osteoclasts...

Cardiac mass can be described as an abnormal structure within or directly contiguous to the heart. Tumors and thrombi are the most common types of cardiac masses. Intracardiac thrombi have been encountered in various clinical settings and can result in severe morbidity and mortality due to embolic events. Cardiac neoplasms are extremely rare, and are usually metastatic tumors. The major primary malignancies associated with cardiac metastases include cancers of the lung, breast, stomach, and liver, and lymphoma, leukemia, and melanoma...
