BACKGROUND AND AIMS This study aimed to access possible relationships between breast cancer subtypes and sites of distant metastasis in breast cancer. RESULTS A total of 243,896 patients, including 226,451 cases in control groups were identified. Bone metastasis was found in 8848 cases, compared with 1,000 brain metastasis cases, 3434 liver metastasis cases and 4167 lung metastasis cases. Pat...
Metastasis accounts for most of the deaths from breast cancer and the preference of invasive breast cancer metastasising to bone has been widely reported. However, the biological basis of breast cancer osteotropism is not fully understood. This paper provides, for the first time, an integrative, systematic review of evidence of molecular factors that have functional roles in the homing of metas...
Tumor-bone cell interactions are critical for the development of metastasis-related osteolytic bone destruction. In this issue of Cancer Cell, Ell and colleagues show how a discrete miRNA network regulates osteoclastogenesis during breast cancer bone metastasis. A signature of upregulated miRNAs may have diagnostic and therapeutic implications for bone metastases.
In order to become established in the skeleton, metastatic cells disseminating from the breast carcinoma need to acquire organ-specific traits. There are no effective predictors for who will develop bone metastasis to guide long-term predictive therapy. Our purpose was to individuate events critical for bone colonization to make a molecular classification of breast carcinoma useful for bone-met...
Purpose. Experimental data suggest that tumour cells can reversibly transition between epithelial and mesenchymal states (EMT and MET), a phenomenon known as cellular plasticity. The aim of this review was to appraise the clinical evidence for the role of cellular plasticity in prostate cancer (PC) bone metastasis. Methods. An electronic search was performed using PubMed for studies that have e...
Bone metastasis occurs in the majority of late-stage tumors with poor prognosis. It is mainly classified as osteoblastic metastasis and osteolytic metastasis. The pathogenesis of osteolytic metastasis is a "vicious cycle" between tumor cells and bone cells (primarily the osteoclasts), which is mediated by secretory factors. The P62 adapter protein is a versatile multitasker between tumor cells ...
Bone metastases are frequent and debilitating consequence for many tumors, such as breast, lung, prostate, and kidney cancer. Many studies report the importance of the immune system in the pathogenesis of bone metastasis. Indeed, bone and immune system are strictly linked to each other because bone regulates the hematopoietic stem cells from which all cells of the immune system derive, and many...
Treatment of bone metastasis is a major challenge for current and future orthopedic and oncology specialists. For the treatment of single metastases, there is a continuing search for effective local treatments that do not affect the whole patient. The current report describes the case of single breast cancer metastasis to the pelvic bone in a 50-year-old woman treated surgically by bone osteoto...
UNLABELLED Metastatic tumors have been shown to establish permissive microenvironments for metastases via recruitment of bone marrow-derived cells. Here, we show that metastasis-incompetent tumors are also capable of generating such microenvironments. However, in these situations, the otherwise prometastatic Gr1(+) myeloid cells create a metastasis-refractory microenvironment via the induction ...
Bone metastasis is the most common complication in patients with solid tumors. Osteoclastogenesis and bone resorption contribute to the pathophysiology of osteoblastic bone metastasis, likewise with osteolytic bone metastasis types. Semaphorin 3A (Sema 3A) has been shown to inhibit RANKL-induced immunoreceptor tyrosinebased activation motif signaling and osteoclastic differentiation, as well as...
