Clohisy DR, Perkins SL, Ramnaraine ML: Review of cellular mechanisms of tumor osteolysis. Metastastic human breast cancer cells (MDA-MB-231) added to this culture attach, penetrate the tissue and form single cell files characteristic of metastases seen in pathologic tissues. 2 Of interest is that patients with blastic (versus osteolytic) bone metastases have been reported to have prolonged survival. 2002, 13: 62-71. In the bone, OPN is involved in the differentiation and activity of osteoclasts, and inhibition of mineral deposition in the osteoid [37]. Mercer RR, Mastro AM: Cytokines secreted by bone-metastatic breast cancer cells alter the expression pattern of f-actin and reduce focal adhesion plaques in osteoblasts through PI3K. Symptoms when breast cancer has spread to the bones . Denosumab is an antibody directed to RANKL that prevents osteoclast differentiation. PubMed 2003, 89: 2031-2037. It binds to two class III tyrosine kinase receptors, PDGFR and PDGFR, leading to activation of several signaling molecules. Of the many prostaglandins, PGE2 is known to play a critical role in cancer progression. Edited by: Rosen CL. volume12, Articlenumber:215 (2010) Bone. There are two types of lesions: lytic lesions, which destroy bone material; and blastic lesions, which fill the bone with extra cells. In a recent comprehensive review article, Lynch [50] presents the case that they are 'master regulators' of the vicious cycle. 10.1111/j.0105-2896.2005.00326.x. These capacities are essential for any cancer cells to develop distant metastases in organs such as lungs and liver as well as bone. 2010, 70: 6537-6547. 10.1056/NEJMoa030847. As pointed out by Lynch, the spatial and temporal expression of these molecules is of utmost importance. Privacy 10.1016/S0959-8049(00)00363-4. The authors declare that they have no competing interests. California Privacy Statement, Exp Cell Res. PMC With rare exceptions, cancer that has spread to the bones can't be cured. Meanwhile, COX-2 produced by breast cancer cells and osteoblasts increases the localized PGE2 concentration, which can directly bind to osteoblasts, promoting RANKL expression and further stimulating osteoclast differentiation. Kang and colleagues [20] found that expression of two MMP genes, MMP1 and ADAMTS1, discriminated between a subline of osteotropic metastatic MDA-MB-231 cells and the parental line. In this process, the older bone doesn't break down while the new bone forms. 10.1210/endo-86-6-1436. Cells of the monocyte-macrophage lineage are stimulated to form osteoclast progenitor cells. Google Scholar. A large-scale 2017 study of the 10 most common cancers with bone metastasis found: Lung cancer had the lowest 1-year survival rate after bone metastasis (10 percent). It is required to drive mesenchymal cells to become osteoblasts. Cancer Res. Clin Cancer Res. Bethesda, MD 20894, Web Policies EMBO J. Evidence to support the concept that there is an intimate relationship between breast cancer cells and osteoclasts is described using an in vivo bone metastasis model in which human breast cancer cells are inoculated into the left ventricle of nude mice. 2010, 36: 615-620.

Once breast cancer cells arrest in bone, bone is a storehouse of a variety of cytokines and growth factors and thus provides an extremely fertile environment for the cells to grow. Osteoblasts produce macrophage colony stimulating factor (M-CSF) and receptor activator of NFB ligand (RANKL), which bind to their respective receptors, c-fms and RANK, on pre-osteoclasts to bring about osteoclast differentiation and activation. PubMed 2010, 70: 1835-1844. Estrogen also increases osteoblast pro-collagen synthesis and decreases osteoblast apoptosis [63]. IGF binding initiates production of M-CSF and RANKL by osteoblasts and c-fms and RANK by osteoclasts [54].

Kingsley LA, Fournier PG, Chirgwin JM, Guise TA: Molecular biology of bone metastasis. Several of these RANKL inducers merit further discussion with respect to metastatic breast cancer-induced osteolysis. In a study by Mercer and Mastro [59], osteoblasts treated with conditioned media from MDA-MB-231 breast cancer cells displayed disorganized F-actin fibrils and reduced focal adhesion plaques. 2006, 85: 596-607. Clinical evidence indicates that this drug can reduce the rate of bone loss, but is not curative. Bone metastasis significantly affects both quality of life and survival of the breast cancer patient. Google Scholar, Mundy GR: Bone Remodeling and its Disorders. Immunol Rev. The cells that have spread to the bone are breast cancer cells. However, the presence of metastatic breast cancer cells or other bone metastatic cancers, such as prostate, lung, renal, and myeloma, accelerates the remodeling process and disturbs the balance between bone depositing cells, osteoblasts, and bone degrading cells, osteoclasts. Y-CC is a senior graduate student completing work on the studies of selenium in breast cancer metastasis. This approach will allow testing of components and drugs in a model less complex than an animal but more relevant than standard tissue culture. 10.1016/j.ctrv.2010.04.003. Chronic inflammation has long been considered a risk factor in cancer initiation [68]. 10.1158/1535-7163.MCT-07-0234. Clin Exp Metastasis. Unfortunately, some of the therapies used for breast cancer patients may exacerbate the problem. MMP1, 2, 3 process the binding factors and free IGF, allowing it to bind to its receptors found both on osteoblasts and osteoclasts. An Open Label, Phase Ib, Dose-escalation Study Evaluating the Safety and Tolerability of Xentuzumab and Abemaciclib in Patients With Locally Advanced or Metastatic Solid Tumours and in Combination With Endocrine Therapy in Patients With Locally Advanced o. In people with breast and prostate cancer, the bone is often the first distant site of cancer spread. However, the MMPs may be involved in matrix remodeling once the osteoclasts are finished. The role of PTHrP in bone metabolism is not fully understood, but it is known to cause upregulation of RANKL and downregulation of OPG [19], thus enhancing osteoclast function leading to bone degradation. While EMMPRIN is produced normally during tissue remodeling, it increases during tumor progression and metastasis. Coleman RE, Lipton A, Roodman GD, Guise TA, Boyce BF, Brufsky AM, Clzardin P, Croucher PI, Gralow JR, Hadji P, Holen I, Mundy GR, Smith MR, Suva LJ: Metastasis and bone loss: Advancing treatment and prevention. 2008, 473: 98-105.

To accomplish the process of metastasis to bone, breast cancer cells are required to intrinsically possess or acquire the capacities that are necessary for them to proliferate, invade, migrate, survive, and ultimately arrest in bone. Sanchez-Fernandez MA, Gallois A, Riedl T, Jurdic P, Hoflack B: Osteoclasts control osteoblast chemotaxis via PDGF-BB/PDGF receptor beta signaling. Edited by: Rosen CL. In contrast to breast cancer, prostate bone metastasis often results in osteoblastic lesions. While drugs that inhibit osteoclast differentiation or activity are vital to treating osteolysis, therapies designed to restore osteoblast number and function will be required to fully resolve osteolytic lesions. Myeloma cells may also produce RANKL and directly affect osteoclasts [28]. 2005, 92: 1531-1537. Just as osteoblasts are a critical partner in normal bone remodeling, they are vital to the metastatic osteolytic process. At the tissue level, PDGF is involved in bone formation, wound healing, erythropoiesis and angiogenesis as well as tumor growth and lesion development [57]. In addition, production of inflammatory cytokines (that is, IL-6, TNF-, M-CSF, IL-1) is suppressed by estrogen [64]. Cancer. Osteoblastic or blastic metastases cause an area of the bone to look denser or sclerotic. PubMed Recently we have begun developing an in vitro bioreactor [78]. MMPs are involved in the bone remodeling process after osteoclasts are finished. Bone metastasis significantly affects both quality of life and survival of the breast cancer patient. 10.1158/0008-5472.CAN-07-1046. 8600 Rockville Pike They also are regulators of other molecules important in the vicious cycle. In addition, other cells not specific for bone but likely to be found in the bone (macrophages, neutrophils and T lymphocytes) produce MMPs. Survival Prediction in Patients Treated Surgically for Metastases of the Appendicular Skeleton-An External Validation of 2013-SPRING Model. Marie L, Braik D, Abdel-Razeq N, Abu-Fares H, Al-Thunaibat A, Abdel-Razeq H. Cancer Manag Res. The other 20% of primary disease sites in both sexes are: kidney, thyroid, gastrointestinal tract and other locations. Cancer Cell. The resorption phase of the process begins with recruitment of pre-osteoclasts that differentiate into activated osteoclasts under the direction of osteoblasts (Figure 1A). Metastatic breast cancer (also called stage IV or advanced breast cancer) is not a specific type of breast cancer. Trabecular bone is the major site of bone turnover under normal conditions and in diseases of bone loss or formation. However, cathepsin K is also produced by other cells in the bone microenvironment, such as macrophages and bone marrow stromal cells. Ganapathy and colleagues [24] found that TGF- antagonists are able to reduce bone metastasis and the number and activity of differentiated osteoclasts [24]. Another drug, teriparatide (Forteo), the amino-terminal 34 amino acids of parathyroid hormone, has been used for many years to treat osteoporosis. Below are the links to the authors original submitted files for images. Cookies policy. However, teriparatide is associated with an increased risk of osteosarcoma and exacerbation of skeletal metastases because of its effect on bone turnover [75]. J Mammary Gland Biol Neoplasia. Bone is the most common site of metastasis for breast cancer. Breast cancer is often compared with prostate cancer, which metastasizes to the skeleton with a similar frequency. However, more accessible and defined [76] models are needed. Part of Biochem Biophys Res Commun. Current therapies consist of blocking osteoclast activity as a means of disrupting the vicious cycle. Teriparatide is a recombinant peptide of parathyroid hormone that stimulates osteoblast activity and bone formation. We also discuss known risk factors as well as detection and assessment of bone metastases. 10.1002/(SICI)1097-0142(19971015)80:8+<1546::AID-CNCR4>3.0.CO;2-I. 2022 Feb;22(2):85-101. doi: 10.1038/s41568-021-00406-5. Oncogene. Osteoclasts derive from hematopoietic stem cells. PubMed Osteocytes may act as mechanosensing cells and initiate the process when microfractures and loading are involved. Myeloma cells produce factors that upregulate osteoblast production of M-CSF and RANKL and downregulate production of OPG. It has also been suggested that Runx2 is ectopically expressed in bone-destined metastatic breast cancer cells. 2008, 3: e3537-10.1371/journal.pone.0003537. These molecules not only help support tumor cells, but also are osteoclastogenic. N Engl J Med. 2010, 363: 2458-2459. The dynamics of this system are interrupted when metastatic breast cancer cells are introduced, adding another layer of active molecules to the bone environment. 10.1007/s10585-006-9044-8. 10.1038/sj.bjc.6602417.

(A) The bone microenvironment under conditions of normal bone remodeling; (B) and in the presence of osteolytic bone metastases. J Bone Miner Res. Abstract Metastasis of breast cancer cells to bone consists of multiple sequential steps. Breast cancer cells can spread to the bone through the lymphatic system or the blood. TGF- is well-known for its role in osteolytic bone metastasis. PDGF is a dimeric protein consisting of two of four possible subunits. PDGF can function as a mitogen for cells of mesenchymal origin and possesses chemoattractant properties, making it an important factor in cell proliferation and migration. For post-menopausal women, high bone turnover may be caused by estrogen deficiency. Oncogene. By knowing the typical behavior of the metastatic lesion - lytic or blastic - you can help sort between the types to make the mnemonic even more useful. Exp Oncol. Article Cancer Treat Rev. Bussard KM, Venzon DJ, Mastro AM: Osteoblasts are a major source of inflammatory cytokines in the tumor microenvironment of bone metastatic breast cancer. Bone metastases from breast cancer are typically lytic, meaning that there is area of bone destruction at the site of metastasis.

Breast cancer frequently metastasizes to the skeleton. Cite this article. Other drugs on the horizon target TGF-, and cathepsin K. Various approaches, including kinase inhibitors, ligand-neutralizing antibodies and anti-sense molecules, are being investigated [33]. What Are The Symptoms Of Bone Metastasis In Breast Cancer. Metastatic cancer cells tend to colonize the heavily vascularized areas of the skeleton, such as the red marrow of the long bones, sternum, pelvis, ribs and vertebrae, where they disrupt not only bone physiology but also hematopoiesis and the immune system [3]. In addition, pre-clinical trials with agents that target cathepsin K, certain matrix metalloproteinases (MMPs), and transforming growth factor (TGF)- are underway. 2018 Mar;96:63-78. doi: 10.1016/j.biocel.2018.01.003.

Their multifunctionality demonstrates their importance. COX-2 activity in breast cancer cells has also been found to modulate the expression and activity of MMPs. Cancer Res. This feature accounts for the variable sensitivity and specificity of different imaging modalities. Before In males, prostate and lung cancers make up 80% of carcinomas metastasising to bone. Metastatic bone lesions are the predominant malignancy to effect bone, with 15 times the occurrence rate of the next most common bone malignancy. Rucci N, Teti A: Osteomimicry: how tumor cells try to deceive the bone. It is common to find increased PTHrP serum levels in breast cancer patients. These types of tumors are called osteolytic, or simply lytic. 2010, 70: 412-424. Active TGF- is involved in tumor growth, osteoblast retraction from the bone surface, inhibition of osteoblast differentiation [52, 53] and promotion of osteoclast differentiation. Furthermore, Pozzi and colleagues [30] have recently reported that high doses of zoledronic acid, the current standard therapeutic for most osteolytic diseases, may also negatively affect osteoblast differentiation. Metastatic breast cancer is breast cancer that has spread beyond the breast and nearby lymph nodes to other parts of the body (most often the bones, lungs, liver or brain). 2000 Jun 15;88(12 Suppl):2979-88. doi: 10.1002/1097-0142(20000615)88:12+<2979::aid-cncr13>3.0.co;2-u. COX-2 inhibition also partially attenuated the ability of two breast cancer cell lines to degrade and invade extracellular matrix components such as laminin and collagen [47]. & Mastro, A.M. 2008, Washington, DC: American Society for Bone and Mineral Research, 374-378. full_text. Osteoblasts themselves are negatively affected by cancer cells as evidenced by an increase in apoptosis and a decrease in proteins required for new bone formation. Endocr Rev. Osteomimetic factors driven by abnormal Runx2 activation in breast cancer cells may increase their survival in the bone microenvironment. SPARC cleavage also coincides with an increase in inflammatory cytokines such as IL-6 and IL-8 [51]. Induction of aberrant osteoclastogenesis is only part of the equation. While breast cancer metastases can have blastic and lytic lesions, myeloma bone lesions are purely osteolytic due to increased osteoclast activity and suppressed osteoblast activity . Bone metastasis may be the first sign that you have cancer, or bone metastasis may occur years after cancer treatment. This area has been likened to an extracellular lysosome [11]. Once bony metastases occur, cancer cure becomes impossible and in these cases radiation therapy, associated or not with systemic chemotherapy, may be . It improves the quality of life by preventing fractures but does not prolong life [73]. Clipboard, Search History, and several other advanced features are temporarily unavailable. The changes in the bone microenvironment then create a vicious cycle that further promotes bone destruction and tumor progression.Various therapeutic options are available for bone metastases of breast cancer. Andrea M Mastro. We are in the process of adding osteoclasts to the system to create a rudimentary in vitro bone remodeling unit. HHS Vulnerability Disclosure, Help 2005, 310: 270-281. Hadjidakis DJ, Androulakis II: Bone remodeling. In middle aged and elderly women, calcium and/or vitamin D deficiencies are quite common, as is the incidence of breast cancer [65]. Orr and colleagues [5] have determined MMPs sufficient to resorb bone in vitro and to contribute to the process in vivo. This increase in COX-2 results in increased secretion of PGE2, which binds to EP4 receptors on the surface of the osteoblasts. -. 2000, 373: 104-114. 10.1007/s00784-009-0268-2. These factors can stimulate the tumor cells to proliferate and produce more growth factors and more PTHrP, further perpetuating the vicious cycle of bone metastasis. The cyclooxygenase enzymes COX-1 and COX-2 catalyze the conversion of arachidonic acid to prostaglandins and thromboxanes. 10.1158/1078-0432.CCR-05-1806.
