Cancer. In addition, its expression is enhanced in the presence of TGF- [20]. Unfortunately, some of the therapies used for breast cancer patients may exacerbate the problem. Teriparatide is a recombinant peptide of parathyroid hormone that stimulates osteoblast activity and bone formation. This article is part of a review series on New pathways of metastasis, edited by Lewis Chodosh. 10.1038/35036374. For females, breast and lung are the most common primary sites ; nearly 80% of cancers that spread to the skeleton are from these locations. Symptoms when breast cancer has spread to the bones . Because bone metastasis is extremely common in patients with metastatic breast cancer, clinical management of bone metastases is an important and challenging aspect of treatment in the metastatic setting.The skeleton is a metabolically active organ system that undergoes continuous remodeling throughout life. 10.1158/0008-5472.CAN-08-1078. Once activated the large multinucleated osteoclasts attach to the bone surface creating a resorption lacuna, a sealed zone in which acid and proteolytic enzymes, such as cathepsin K, are released and degrade the bone matrix. Bone metastasis can occur in any bone but more commonly occurs in the spine, pelvis and thigh. Osteomimetic factors include osteopontin (OPN), osteocalcin, osteonectin, bone sialoprotein, RANKL and PTHrP. PMC 2008, Washington, DC: American Society for Bone and Mineral Research, 379-382. full_text. Bone metastasis can cause pain and broken bones. Primer on the Metabolic Bone Diseases and Disorders of Mineral Metabolism. Endocrinology. Andrea M Mastro. 1991 Jul 12;66(1):107-19 2005, 310: 270-281. It is a reservoir of numerous growth factors as well as calcium and phosphorous, which are released from the matrix during bone remodeling. 10.1007/s10585-004-1867-6. It is now known that PGE2 signaling through its receptor EP4 plays a crucial role in osteolysis by inducing monocytes to form mature osteoclasts. (B) Metastatic breast cancer cells in the bone microenvironment secrete parathyroid hormone-related protein (PTHrP), cytokines and growth factors that negatively impact osteoblast function. The dynamics of this system are interrupted when metastatic breast cancer cells are introduced, adding another layer of active molecules to the bone environment. Clinical Characteristics, Prognostic Factors and Treatment Outcomes of Patients with Bone-Only Metastatic Breast Cancer. Roy DL, Pathangey LB, Tinder TL, Schettini JL, Gruber HE, Mukherjee P: Breast-cancer-associated metastasis is significantly increased in a model of autoimmune arthritis. J Bone Oncol. There is evidence that bisphosphonates also contribute to tumor cell death, especially in combination with chemotherapy [72]. 2010, [Epub ahead of print]. Myeloma cells produce factors that upregulate osteoblast production of M-CSF and RANKL and downregulate production of OPG. Article Estrogen also increases osteoblast pro-collagen synthesis and decreases osteoblast apoptosis [63]. 10.1007/s10585-007-9112-8. Clin Orthop Relat Res. break). The main symptoms of breast cancer that has spread to bone are: McHayleh W, Ellerman J, Roodman D: Hematologic malignancies and bone. Clinically, complications secondary to bone metastasis include pain, pathologic fractures, spinal cord compression, and hypercalcemia of malignancy. Osteoblasts and bone stromal cells can respond to a variety of substances that upregulate RANKL. 2001, 37: 106-113. statement and 10.1158/0008-5472.CAN-10-2179. Cancer Cell. 2012 Aug;39(8):1174-7. IL-8, a proinflammatory CXC chemokine, is secreted by monocytes, endothelial cells and osteoblasts. These molecules bind to hydroxyapatite of the bone matrix and are ingested by osteoclasts, which then undergo apoptosis. In the 1960s and 70s it was proposed that bone degradation might result from the physical pressure of the tumor on the bone and/or direct resorption of the bone by tumor cells. Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. Bone metastases may cause pain, may make the bones more susceptible to fractures, and may cause increased levels of calcium in the blood. While the outcome is predominantly osteoblastic, it is known that prostate cancer lesions display both blastic and lytic characteristics early in the process. 10.1158/0008-5472.CAN-09-4092. 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. We are in the process of adding osteoclasts to the system to create a rudimentary in vitro bone remodeling unit. This feature accounts for the variable sensitivity and specificity of different imaging modalities. Osteoblastic or blastic metastases cause an area of the bone to look denser or sclerotic. Cancer Res. Most breast cancer metastasis to bone results in osteolytic lesions. In the final stages of metastatic osteolytic breast cancer disease, the cancer cells, fueled by growth factors released from the degraded matrix, expand unchecked. 10.3816/CBC.2005.s.004. Several of these molecules are related to the recruitment and differentiation of osteoclasts; some are prominent players in the vicious cycle. They follow the osteoclasts, reforming the bone matrix. Halpern J, Lynch CC, Fleming J, Hamming D, Martin MD, Schwartz HS, Matrisian LM, Holt GE: The application of a murine bone bioreactor as a model of tumor: bone interaction. The purpose of this study is to find a safe dose of: - Xentuzumab in combination with abemaciclib - Xentuzumab in combination with abemaciclib and hormonal therapies The study also tests whether these medicines make tumours shrink in participants with lung and breast cancer. For post-menopausal women, high bone turnover may be caused by estrogen deficiency. Bone metastases from breast cancer are typically lytic, meaning that there is area of bone destruction at the site of metastasis. Clin Oral Investig. Phadke PA, Mercer RR, Harms JF, Jia Y, Frost AR, Jewell JL, Bussard KM, Nelson S, Moore C, Kappes JC, Gay CV, Mastro AM, Welch DR: Kinetics of metastatic breast cancer cell trafficking in bone. The bone remodeling microenvironment is a complex system in which the cell functions are controlled by multifunctional transcription factors, cytokines and growth factors. Lerner UH: Inflammation-induced bone remodeling in periodontal disease and the influence of post-menopausal osteoporosis. Rucci N, Teti A: Osteomimicry: how tumor cells try to deceive the bone. Osteocytes may act as mechanosensing cells and initiate the process when microfractures and loading are involved. In the process, growth factors stored in the matrix, such as transforming growth factor (TGF)-, vascular endothelial growth factor (VEGF), insulin-like growth factors (IGFs), bone morphogenic proteins and fibroblast-derived factors, as well as calcium, are released into the bone microenvironment. Breast cancer cells can spread to the bone through the lymphatic system or the blood. Endocrinology. Understanding the mechanisms of osteolysis should be the key to designing the cure. Once osteoblasts finish bone deposition, they undergo apoptosis, remain in the matrix as osteocytes or revert to thin bone-lining cells. The lesions can often be blastic but may also appear purely lytic, with poor margination, no matrix and cortical destruction. At least three major growth factors sequestered in the matrix are activated by MMPs. The mean standardized uptake value (SUV) for tumor was 7.1 versus 2.1 for benign lesions. Several groups have developed in vivo models in which bone or bone substitutes are implanted in animals. 2010, 115: 140-149. CAS These approaches still rely on animals. The presence of metastatic lesions in bone disrupts the normal bone microenvironment and upsets the fine balance between the key components. Oncogene. 2002, 13: 62-71. Privacy 2006, 85: 596-607. It is common to find increased PTHrP serum levels in breast cancer patients. This increase in COX-2 results in increased secretion of PGE2, which binds to EP4 receptors on the surface of the osteoblasts. We present therapeutic options for bone metastasis using a multidisciplinary approach. Bone remodeling is often described as a cycle beginning with bone degradation and ending with bone deposition (Figure 1A). Curr Opin Support Palliat Care. Before 3 MMP1, 2, 3 process the binding factors and free IGF, allowing it to bind to its receptors found both on osteoblasts and osteoclasts. Denosumab is an antibody directed to RANKL that prevents osteoclast differentiation. 2010, 8: 159-160. J Dent Res. This information is not easily obtained with in vitro studies.

Home; Study Search; Study Details From Other Databases Another drug, teriparatide (Forteo), the amino-terminal 34 amino acids of parathyroid hormone, has been used for many years to treat osteoporosis. 2010. It should be noted that in addition to obvious members of the vicious cycle, other factors are produced during the process, including inflammatory cytokines, which significantly affect tumor cell survival, cell differentiation, and angiogenesis. Because of its significant role, TGF- has been a tempting therapeutic target. PloS one. Those leading to excess bone deposition are considered osteoblastic. Breast Cancer Res. Nat Cell Biol. Br J Cancer. Bone is the most common site of metastasis for breast cancer. Recently, we have found that metastatic breast cancer cells have profound effects on osteoblasts in culture [22] and in animals [31, 32]. Proff P, Romer P: The molecular mechanism behind bone remodelling: a review. Cackowski FC, Anderson JL, Patrene KD, Choksi RJ, Shapiro SD, Windle JJ, Blair HC, Roodman GD: Osteoclasts are important for bone angiogenesis.

Once bony metastases occur, cancer cure becomes impossible and in these cases radiation therapy, associated or not with systemic chemotherapy, may be . Laufer I, Lis E, Pisinski L, Akhurst T, Bilsky MH. Y-CC is a senior graduate student completing work on the studies of selenium in breast cancer metastasis. 2007, 6: 2609-2617. It has also been suggested that Runx2 is ectopically expressed in bone-destined metastatic breast cancer cells. Brown JE, Thomson CS, Ellis SP, Gutcher SA, Purohit OP, Coleman RE: Bone resorption predicts for skeletal complications in metastatic bone disease. In doing so, cancer cells are equipped to home, adhere, survive and proliferate in the bone microenvironment. Sanchez-Fernandez MA, Gallois A, Riedl T, Jurdic P, Hoflack B: Osteoclasts control osteoblast chemotaxis via PDGF-BB/PDGF receptor beta signaling. Epub 2021 Oct 5. J Bone Miner Res. Mol Cancer Ther. Below are the links to the authors original submitted files for images. Careers. Cortical bone provides strength and protection while trabecular bone is the most metabolically active. In addition, other cells not specific for bone but likely to be found in the bone (macrophages, neutrophils and T lymphocytes) produce MMPs. Lefley D, Howard F, Arshad F, Bradbury S, Brown H, Tulotta C, Eyre R, Alfrez D, Wilkinson JM, Holen I, Clarke RB, Ottewell P. Breast Cancer Res. 2003, 89: 2031-2037. In the early 1970 s it was reported that prostaglandins could resorb fetal bone in culture [43], and that aspirin, a COX-1 inhibitor, and indomethacin, a COX-2 inhibitor, could prevent osteolysis in tissue culture [44]. When a patient has a metastasis and no site of origin can be found (a metastasis of unknown origin) the most likely site is the lung or kidney. J Cell Biochem. Bookshelf Bone lining cells appear microscopically as relatively undifferentiated cells that line the bone. Development of clinically relevant in vivo metastasis models using human bone discs and breast cancer patient-derived xenografts. 10.1177/154405910608500703. 2006, 21: 1350-1358. 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. Bone metastasis may be the first sign that you have cancer, or bone metastasis may occur years after cancer treatment. Edited by: Rosen CL. However, PTHrP does not directly stimulate osteoclast differentiation, but rather stimulates other cells to increase RANKL and decrease OPG production. Larkins TL, Nowell M, Singh S, Sanford GL: Inhibition of cyclooxygenase-2 decreases breast cancer cell motility, invasion and matrix metalloproteinase expression. Mol Cancer Ther. 2008, 7: 2807-2816. Int J Cancer. 1973, 28: 316-321. Thus, in the course of the osteolytic process, the osteoblasts are unable to fulfill their role as bone building cells. IGF, insulin-like growth factor; MCP-1, monocyte chemotactic protein-1; PDGF, platelet-derived growth factor; VEGF, vascular endothelial growth factor. This area has been likened to an extracellular lysosome [11]. Cancer Res. Due to this, the bones get harder and cause the condition called sclerosis. The entry of breast cancer cells into the bone micro-environment synergistically increases the complexity of cell-cell interactions. 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]. Adv Drug Deliv Rev. 10.1038/sj.bjc.6601437. Osteoblasts derive from mesenchymal stem cells in the marrow under control of Runx2, a key osteoblastic transcription factor. Bone metastases are areas of cancer that develop when breast cancer cells travel to the bones. Several MMPs (MMP2, 3, 9) can release TGF- from the latent state, allowing it to become active. 2006, 85: 584-595. There is also evidence that molecules in conditioned medium from PC-3 cells alone [34], or from both PC-3 cells and MC3T3-E1 osteoblasts [35], promote osteoclastogenesis. These capacities are essential for any cancer cells to develop distant metastases in organs such as lungs and liver as well as bone. 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. 1984, 235: 561-564. Another growth factor sequestered in the matrix is IGF. When the bone loss is extensive, the osteoblasts are absent from the lesion [32]. DMS is a senior research technician with many years experience in the bone field. & Mastro, A.M. Annu Rev Pathol. In addition, production of inflammatory cytokines (that is, IL-6, TNF-, M-CSF, IL-1) is suppressed by estrogen [64]. 2022 Feb;22(2):85-101. doi: 10.1038/s41568-021-00406-5. 1997, 80 (8 Suppl): 1546-1556. Both RANKL and VEGF can induce osteoclast formation [48], and MMPs play a role in bone matrix degradation. Breast cancer frequently metastasizes to the skeleton. Bethesda, MD 20894, Web Policies It's the most advanced stage of breast cancer. IL-11, normally produced by bone marrow stromal cells and osteoblasts, is an important regulator of hematopoiesis and a potent promoter of osteoclast formation. CAS Current treatments can improve bone density, decrease skeletal related events and ease bone pain, yet existing bone lesions do not heal. Aldridge SE, Lennard TW, Williams JR, Birch MA: Vascular endothelial growth factor acts as an osteolytic factor in breast cancer metastases to bone. It is interesting that cancer cells often remain dormant in bone for many years before they begin to grow. In this context, RANKL increases in the presence of inflammatory agents from infectious organisms, such as lipopolysaccharide, CpGpDNA and viral double-stranded DNA [41]. VEGF also forms a complex with the extracellular matrix [31, 55]. Raica M, Anca M: Platelet-derived growth factor (PDGF)/PDGF receptors (PDGFR) axis as target for antitumor and antiangiogenic therapy. Doctors use imaging tests, such as x-rays, to figure out the types of . 2001, 142: 5050-5055. At least three essential molecules, TGF-, IGF, and VEGF, need to be activated by MMPs before they can function. 2010. Cell Tissue Res. Drugs of the bisphosphonate family have been used for many years as the standard of care. Recently we have begun developing an in vitro bioreactor [78]. Evidence from an intratibial bone metastasis model indicates that when highly aggressive metastatic MDA-MB-231 cells express dysfunctional Runx2 or small hair-pin RNA for Runx2, both osteoclastogenesis and osteolytic lesions decrease [40]. Chronic inflammation has long been considered a risk factor in cancer initiation [68]. Cells of the osteoblast lineage are derived from mesenchymal stem cells, and are represented in this unit by osteoblasts, bone lining cells and osteocytes. 2007, 24: 599-608.

PTH/PTHrP, TNF-, prostaglandins (PGE2), IL-1, IL-11, FGF-2, and IGF-1 have been reported to increase RANKL production. 2010, 33 (3 Suppl): S1-7. Denosumab (Prolia), the latest drug to enter the field, is a monoclonal antibody to RANKL. Breast cancer cells also cause inhibition of osteoblast differentiation and adhesion, downregulation of collagen synthesis and increased osteoblast apoptosis. They activate latent molecules released from the matrix. Article 2003, 3: 537-549. In fact, a new drug, denosumab (Prolia), a fully human monoclonal antibody to RANKL, has been approved by the US Food and Drug Administration (FDA) for the treatment of postmenopausal women with high risk of osteoporotic fractures, and is under priority review for patients with bone metastases. Breast cancer metastasis to the bone: mechanisms of bone loss. On x-rays, these metastases show up as spots that are whiter than the bone around them.

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. 2005, 208: 194-206. (A) The bone remodeling unit consists of osteoblasts, which produce osteoid, bone matrix, and osteoclasts, which degrade mineralized bone. The mechanisms are thought to be inhibition of tumor cell adhesion as well as osteoclast differentiation. It was also noted that tumor cells caused other cells in the bone (for example, lymphocytes) to produce molecules such as prostaglandins (PGs) that can affect bone [4]. Osteoblast differentiation is suppressed; new osteoid production is no longer able to keep pace with bone resorption. 2022 Dec 2;11(12):2394. doi: 10.3390/antiox11122394. Of the many prostaglandins, PGE2 is known to play a critical role in cancer progression. Am J Clin Oncol.

In advanced disease, bone formation is essentially absent, and the processes of bone resorption and formation become uncoupled. 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. 2009, 69: 4097-4100.

Until recently they were the only FDA approved drugs for metastatic bone disease [71]. This loss is more precipitous in women, due to the decrease in estrogen at menopause [3]. Please enable it to take advantage of the complete set of features! The blastic bone lesions are caused when the cancer cells release the fluids. These drugs may also cause cancer cell death; however, they may also negatively affect osteoblasts. 2022 Aug 6;10(8):1908. doi: 10.3390/biomedicines10081908. 2006, 12: 1431-1440. 10.1210/er.19.1.18.

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). Troen BR: Molecular mechanisms underlying osteoclast formation and activation. Brook N, Brook E, Dharmarajan A, Dass CR, Chan A. Int J Biochem Cell Biol. The ratio of RANKL to OPG determines the extent of the osteoclast activity and bone degradation. Induction of aberrant osteoclastogenesis is only part of the equation. 2010, 9: 122-10.1186/1476-4598-9-122. SPARC cleavage also coincides with an increase in inflammatory cytokines such as IL-6 and IL-8 [51]. 2008, 34 (Suppl 1): S25-30. Cells of the immune system, T cells and dendritic cells can also express RANKL. The resorption phase of the process begins with recruitment of pre-osteoclasts that differentiate into activated osteoclasts under the direction of osteoblasts (Figure 1A). -, Cell. It binds to two class III tyrosine kinase receptors, PDGFR and PDGFR, leading to activation of several signaling molecules. TGF- is one of the most prominent. 1999, London: Martin Dunitz Ltd. Raisz LG, Mundy GR, Luben RA: Skeletal reactions to neoplasms. Nevertheless, the inaccessibility, opacity and size of the skeleton make it difficult to study even in laboratory animals. 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. It has been suggested that cancer cells preferentially metastasize to bone due to their ability to express genes that are normally considered bone or bone-related [36]. Cells of the monocyte-macrophage lineage are stimulated to form osteoclast progenitor cells. 10.1016/j.yexcr.2007.09.021. More than 2 out of 3 breast and prostate cancers that . This process is effected by osteoblasts and osteoclasts within a functional and anatomic unit known as the basic multicellular unit (BMU). PTHrP is expressed in the primary tumors of about 50% of patients and in more than 90% of breast cancer bone metastasis samples [18]. 2009, 175: 1255-1269. Eur J Cancer. 2010, 126: 1749-1760. In this process, the older bone doesn't break down while the new bone forms. Their function is not clear except that their retraction is necessary for bone resorption to begin [10]. The osteoclasts work as part of the bone remodeling compartment, underneath a canopy of bone lining cells.
