The dynamics of this system are interrupted when metastatic breast cancer cells are introduced, adding another layer of active molecules to the bone environment. Breast cancer bone metastases: pathogenesis and therapeutic targets. It is common to find increased PTHrP serum levels in breast cancer patients. 2000, 373: 104-114. Chemotherapy may bring about ovarian failure and premature menopause [1]. Often, bone metastases have both lytic and blastic features. 2010, 9: 122-10.1186/1476-4598-9-122. -, Proc Natl Acad Sci U S A. At first glance it would seem ideal to pair bisphosphonates or denosumab with teriparatide since the former two block bone resorption and the latter stimulates bone deposition. Cancer Treat Rev. 2023 BioMed Central Ltd unless otherwise stated. There is evidence that bisphosphonates also contribute to tumor cell death, especially in combination with chemotherapy [72]. Please enable it to take advantage of the complete set of features! For females, breast and lung are the most common primary sites ; nearly 80% of cancers that spread to the skeleton are from these locations. All three doctors say that new, progressive pain in your bones or joints is the most common symptom of metastatic breast cancer in bones. 2007, 24: 599-608. In addition, its expression is enhanced in the presence of TGF- [20]. Breast cancer-derived factors facilitate osteolytic bone metastasis. However, cathepsin K is also produced by other cells in the bone microenvironment, such as macrophages and bone marrow stromal cells. Adv Drug Deliv Rev. 2010, [Epub ahead of print]. Angiogenesis inhibitor TNP-470 inhibits human breast cancer osteolytic bone metastasis in nude mice through the reduction of bone resorption. The PGE2-mediated production of RANKL induces osteoclastogenesis via RANK. Jemal A, Siegel R, Ward E, Murray T, Xu J, Thun MJ: Cancer Statistics, 2007.

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. Clohisy DR, Perkins SL, Ramnaraine ML: Review of cellular mechanisms of tumor osteolysis. 10.1016/S0531-5565(03)00069-X. 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 . EMBO J. IGF, insulin-like growth factor; MCP-1, monocyte chemotactic protein-1; PDGF, platelet-derived growth factor; VEGF, vascular endothelial growth factor. 2010, 3: 572-599. HHS Vulnerability Disclosure, Help Osteocytes are terminally differentiated osteoblasts that become embedded in the bone matrix at the end of the deposition phase of remodeling. Temporal and spatial changes in bone mineral content and mechanical properties during breast-cancer bone metastases. 2001, 285: 335-339. Lipton A: Bone continuum of cancer. PGE2 is associated with inflammation, cell growth, tumor development and metastasis [42]. The authors declare that they have no competing interests. Just as osteoblasts are a critical partner in normal bone remodeling, they are vital to the metastatic osteolytic process. More than 2 out of 3 breast and prostate cancers that . It's not the same as having cancer that starts in the bone. Careers. Bisphosphonates binding to hydroxyapatite are ingested by osteoclasts and cause their apoptosis. Google Scholar. However, teriparatide is associated with an increased risk of osteosarcoma and exacerbation of skeletal metastases because of its effect on bone turnover [75]. Metastases leading to overall bone loss are classified as osteolytic. 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. Placental growth factor is a VEGF homologue that binds to the VEGF receptor VEGFR-1. 10.1038/clpt.2009.312. IGF binding proteins keep this molecule latent. MMP-9 is important in the cascade leading to activation of VEGFA. Breast Cancer Res 12, 215 (2010). 2008, 314: 173-183. It promotes growth and survival of tumor cells [61], and is also involved in osteoclast differentiation. 2006, 21: 1350-1358. Osteoblasts and bone stromal cells can respond to a variety of substances that upregulate RANKL. The https:// ensures that you are connecting to the Cancers (Basel). While not directly responsible for osteolysis in metastatic breast cancer disease, there are physiological parameters that can amplify the degree of bone loss. Proteolytic cleavage of SPARC releases biologically active cleavage products that affect angiogenesis factors such as VEGF, platelet-derived growth factor (PDGF) and FGF-2. Thus, bone loss is due to both increased activation of osteoclasts and suppression of osteoblasts. Fragments of human fetal bone implanted in SCID mice allow one to examine human cancer with human bone [76]. In the highly metastatic, COX-2-expressing breast cancer cell line Hs578T, treatment with the selective COX-2 inhibitor Ns-398 markedly decreased the production of MMP1, 2, 3, and 13 in a dose-dependent manner. Its common for people to have lytic and blastic lesions at the same time. These cells fuse to form multinucleated, but non-functional pre-osteoclasts. 10.1210/en.142.12.5050. American Society of Clinical Oncology Bisphosphonates Expert Panel. Kang Y, Siegel PM, Shu W, Drobnjak M, Kakonen SM, Cordon-Cardo C, Guise TA, Massague J: A multigenic program mediating breast cancer metastasis to bone. 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. N Engl J Med. There is evidence in both humans and animals that bone loss in osteolytic metastasis is partly due to the failure of the osteoblasts to produce new osteoid for the bone matrix. Osteoclasts derive from mononuclear myeloid precursors that fuse to form pre-osteoclasts. Evolving cancer-niche interactions and therapeutic targets during bone metastasis. 1998, 19: 18-54. 2022 Aug 23;14:2519-2531. doi: 10.2147/CMAR.S369910. Bone. Bone remodeling is often described as a cycle beginning with bone degradation and ending with bone deposition (Figure 1A). It is impossible to understand the growth and progression of cancer cells in the bone marrow without consideration of the interaction between osteoblasts and osteoclasts. This remarkable process of bone degradation and formation is synchronized by direct cell contact and a variety of secreted factors (Table 1). Bone metastases from breast cancer are typically lytic, meaning that there is area of bone destruction at the site of metastasis. Under the influence of macrophage colony-stimulating factor (M-CSF) and RANKL (receptor activator for NFB ligand) produced by osteoblasts and other cells in the microenvironment, pre-osteoclasts differentiate into multinuclear, activated osteoclasts that adhere to the bone and begin matrix degradation. While COX-1 is constitutively expressed in most tissues, COX-2 expression appears to be limited to brain, kidney, bone, reproductive organs and some neoplasms. 3 Raica M, Anca M: Platelet-derived growth factor (PDGF)/PDGF receptors (PDGFR) axis as target for antitumor and antiangiogenic therapy. Cytokines such as IL-6, IL-8 and IL-11 secreted by breast cancer cells also promote osteoclast differentiation and bone resorption. Metastatic breast cancer cells or their conditioned media increase osteoblast apoptosis, and suppress osteoblast differentiation and expression of proteins required for new bone matrix formation. We present therapeutic options for bone metastasis using a multidisciplinary approach. 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. 2003, 38: 605-614. 2004, 26: 179-184. While they are categorized into functional groups, it should be noted that many of these factors are multifunctional and must be considered within the context of the bone remodeling system as a whole. While the case for the importance of MMPs as metastasis regulators is strong, they themselves are regulated by tissue inhibitors of metalloproteinase (TIMPs). 2010, 36: 615-620. Bone metastasis significantly affects both quality of life and survival of the breast cancer patient. Several of these RANKL inducers merit further discussion with respect to metastatic breast cancer-induced osteolysis. Nevertheless, they do not appear to function in the osteoclast resorption lacuna, probably due to the low pH in this compartment. (B) Metastatic breast cancer cells in the bone microenvironment secrete parathyroid hormone-related protein (PTHrP), cytokines and growth factors that negatively impact osteoblast function. Coleman R, Gnant M: New results from the use of bisphosphonates in cancer patients. The main symptoms of breast cancer that has spread to bone are: Thus, cathepsin K is a key molecule not only in osteoclastic breakdown of collagen but also in angiogenesis and production of proinflammatory cytokines. Bone metastasis may be the first sign that you have cancer, or bone metastasis may occur years after cancer treatment. Clin Adv Hematol Oncol. Annu Rev Pathol. However, once bone metastasis has occurred, the aim has been to break the osteolytic cycle by targeting osteoclasts. Mouse Models of Tumor Bone Metastasis and Invasion for Studying CCN Proteins. 10.1210/er.19.1.18. Thus, inflammation is likely to be important in cancer initiation, metastasis and the resulting osteolysis. MMPs are involved in the bone remodeling process after osteoclasts are finished. A newly discovered molecule downstream of RANKL is extracellular matrix metalloproteinase inducer (EMMPRIN)/CD147, a cell surface glycoprotein that is known to induce MMPs and VEGF [48]. Guise TA, Kozlow WM, Heras-Herzig A, Padalecki SS, Yin JJ, Chirgwin JM: Molecular mechanisms of breast cancer metastases to bone. This feature accounts for the variable sensitivity and specificity of different imaging modalities. Cells of the immune system, T cells and dendritic cells can also express RANKL. 1991 Jul 12;66(1):107-19 10.2353/ajpath.2009.080906. J Bone Miner Res. Epub 2018 Jan 5. Pharmaceuticals. Bone is the most common site of metastasis for breast cancer. The majority of bone metastases are asymptomatic. . -. The MMPs are considered to be important in the bone metastatic process. It is now generally accepted that the bone microenvironment is critical to the colonization and growth or dormancy of metastases. This review summarizes the current understanding of the osteolytic mechanisms of bone metastases, including a discussion of current therapies. Ganapathy and colleagues [24] found that TGF- antagonists are able to reduce bone metastasis and the number and activity of differentiated osteoclasts [24]. Breast Cancer Research PubMed Central In light of these findings, correction of calcium and vitamin D deficiencies should be considered as adjuvant therapies in slowing or preventing osteolysis in breast cancer patients. The blastic bone lesions are caused when the cancer cells release the fluids. 2. 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]. Cancer Cell. 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. This approach will allow testing of components and drugs in a model less complex than an animal but more relevant than standard tissue culture. Bendre M, Montague DC, Peery T, Akel NS, Gaddy D, Suva LJ: Interleukin-8 stimulation of osteoclastogenesis and bone resorption is a mechanism for the increased osteolysis of metastatic bone disease. Bone metastasis can occur in any bone but more commonly occurs in the spine, pelvis and thigh. 10.1016/S0006-291X(02)02937-6. 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. PubMed 10.1359/jbmr.060610. Actions of bisphosphonate on bone metastasis in animal models of breast carcinoma. Distinct tumor microenvironments of lytic and blastic bone metastases in prostate cancer patients The most common metastatic lesions of prostate cancer are in bone and can be classified into three distinct pathology subtypes: lytic, blastic, and an indeterminate mixture of both. Although the mechanisms of osteoteoblastic and osteolytic responses are not fully understood, it is clear that many factors involved in osteolytic breast cancer bone metastasis also regulate the osteolytic aspects of prostate cancer. Smolle MA, Musser E, Bergovec M, Friesenbichler J, Wibmer CL, Leitner L, Srensen MS, Petersen MM, Brcic I, Szkandera J, Scheipl S, Leithner A. 2009, 3: 213-218.

Elazar V, Adwan H, Bauerle T, Rohekar K, Golomb G, Berger MR: Sustained delivery and efficacy of polymeric nanoparticles containing osteopontin and bone sialoprotein antisenses in rats with breast cancer bone metastasis. Bone provides support and protects vital organs but also is a metabolically active tissue. Radiotracer is taken up only by activated osteoblasts and as such, bone scans are quite often negative even with extensive skeletal involvement by myeloma [ 5 ]. 10.1158/1078-0432.CCR-05-1806. Until recently they were the only FDA approved drugs for metastatic bone disease [71]. In patients with lytic or mixed lytic/blastic from solid tumor metastases, there was a 100% concordance between FDG-PET and needle biopsy when using an SUV cutoff of 2 33 33 . and transmitted securely.

There are many excellent reviews describing this paradigm [1417] from its inception in the 1990 s. The minimal essential components are osteoblasts, osteoclasts, tumor cells and the mineralized bone matrix. Primer on the Metabolic Bone Diseases and Disorders of Mineral Metabolism. Due to this, the bones get harder and cause the condition called sclerosis. Klein DC, Raisz LG: Prostaglandins: stimulation of bone resorption in tissue culture.

Bone Rep. 2022 Jun 12;17:101597. doi: 10.1016/j.bonr.2022.101597. Endocrinology. Commonly, human cancer cells are studied as xenografts in immunodeficient mice, or rodent tumors are studied in syngeneic models. There are many suspected factors, such as microfractures, loss of mechanical loading, hormones, cytokines, calcium levels and inflammation. 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. PTH/PTHrP, TNF-, prostaglandins (PGE2), IL-1, IL-11, FGF-2, and IGF-1 have been reported to increase RANKL production. However, both drugs are associated with low incidence of osteonecrosis of the jaw [75]. Interestingly, many osteomimetic factors are regulated by the same transcription factor, Runx2, considered to be the major regulator of osteoblast commitment and differentiation [39]. PubMed Central Induction of aberrant osteoclastogenesis is only part of the equation. Clipboard, Search History, and several other advanced features are temporarily unavailable. Bisphosphonates such as zoledronic acid (Zoledronate) bind to hydroxyapatite of the bone matrix and are ingested by osteoclasts, which then undergo apoptosis. At least three major growth factors sequestered in the matrix are activated by MMPs. Terms and Conditions, 2008, 7: 2807-2816. Metastatic breast cancer (also called stage IV or advanced breast cancer) is not a specific type of breast cancer. 2009, 11: R56-10.1186/bcr2345. 2 Of interest is that patients with blastic (versus osteolytic) bone metastases have been reported to have prolonged survival. 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. PMC 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. Laufer I, Lis E, Pisinski L, Akhurst T, Bilsky MH.

Bethesda, MD 20894, Web Policies Those leading to excess bone deposition are considered osteoblastic. While some of the growth factors produced by breast and prostate cancers may be different, ultimately they engage the bone re-modeling process. 2010, 29: 811-821. This area has been likened to an extracellular lysosome [11]. Inflammation associated with bone fractures and arthritic joints has been anecdotally associated with the appearance of bone metastasis, often many years after the primary tumor has been treated. 10.1158/0008-5472.CAN-07-1046. It is estimated that 85% of individuals with advanced disease harbor bone metastases [1]. 10.1007/s00784-009-0268-2. 2005, 24: 2543-2555.

Request PDF | Mechanoregulation may drive osteolysis during bone metastasis: A finite element analysis of the mechanical environment within bone tissue during bone metastasis and osteolytic . 2006, 6: 181-10.1186/1471-2407-6-181. 8600 Rockville Pike 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]. A working model to describe the bone remodeling compartment in the presence of metastatic cancer cells has been referred to as the 'vicious cycle of bone metastasis' [13] (Figure 1B). Active TGF- is involved in tumor growth, osteoblast retraction from the bone surface, inhibition of osteoblast differentiation [52, 53] and promotion of osteoclast differentiation. CAS 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. Trabecular bone is the major site of bone turnover under normal conditions and in diseases of bone loss or formation. 2010, 48: 483-495. 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. Prostate. Mol Cancer. Neutralization of TGF- in conditioned medium from human metastatic MDA-MB-231 breast cancer cells permitted the differentiation of osteoblasts in culture, suggesting that TGF- negatively affects osteoblasts while promoting growth of the metastatic cells [33]. 7. The receptor binding activity in turn causes an increase in production of RANKL. PubMed Central However, breast cancer cells are unable to progress in bone unless they destroy bone with the assistance of bone-resorbing osteoclasts. The hypoactivity of osteoblasts has been known for some time in multiple myeloma. Further, we describe future directions for bone metastasis management, focusing on novel bone-specific targeted therapies. J Dent Res. quiz S30, CAS Bone. The .gov means its official.

There are conflicting reports regarding their effect on osteoblasts. 1993 Jun 1;90(11):5021-5 However, because TGF- plays a more global role in cell proliferation and differentiation, its utility as a therapeutic may be limited. eCollection 2022. 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. 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. 2008, 473: 98-105. 8600 Rockville Pike 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.

Drugs of the bisphosphonate family have been used for many years as the standard of care. Lung cancer is the third most common site of origin of metastatic cancer deposits in bone, after breast and prostate cancer. Article Increased production of EMMPRIN in turn leads to increases in VEGF and MMPs. It is now known that PGE2 signaling through its receptor EP4 plays a crucial role in osteolysis by inducing monocytes to form mature osteoclasts. PDGF is a dimeric protein consisting of two of four possible subunits. Estrogen has also been shown to promote osteoclast apoptosis and inhibit activation of mature osteoclasts. Marie L, Braik D, Abdel-Razeq N, Abu-Fares H, Al-Thunaibat A, Abdel-Razeq H. Cancer Manag Res. 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). 2010, 70: 6537-6547. 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]. 2009, 175: 1255-1269. However, the process is described in brief in order to further consider the mechanisms of osteolytic metastasis. Current therapies consist of blocking osteoclast activity as a means of disrupting the vicious cycle. C-SRC tyrosine kinase activity is associated with tumor colonization in bone and lung in an animal model of human breast cancer metastasis. Gradient Boosting Machine Identified Predictive Variables for Breast Cancer Patients Pre- and Post-Radiotherapy: Preliminary Results of an 8-Year Follow-Up Study. Abstract Metastasis of breast cancer cells to bone consists of multiple sequential steps. 2006, 1092: 385-396. Some non-cancerous processes can appear similar to metastatic disease to the bone on imaging and MRI.
