Estrogen profoundly affects bone remodeling by suppressing production of RANKL while increasing production of OPG. statement and 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. Cancer Res. Osteoblasts and bone stromal cells can respond to a variety of substances that upregulate RANKL. In males, prostate and lung cancers make up 80% of carcinomas metastasising to bone. There is evidence that osteoblastic metastases form at sites of osteolytic lesions, suggesting an overall increase of bone remodeling Accelerated osteoblastogenesis can be stimulated by factors secreted by prostate cancer cells, such as endothelin-1, TGF-, and fibroblast growth factor (FGF) [1]. While the outcome is predominantly osteoblastic, it is known that prostate cancer lesions display both blastic and lytic characteristics early in the process. 2009, 175: 1255-1269. Unfortunately, some of the therapies used for breast cancer patients may exacerbate the problem. We present therapeutic options for bone metastasis using a multidisciplinary approach. California Privacy Statement, Trabecular bone is the major site of bone turnover under normal conditions and in diseases of bone loss or formation. eCollection 2022 Dec. Edwards CM, Clements ME, Vecchi LA 3rd, Johnson JA, Johnson RW. Guise TA, Mundy GR: Cancer and bone. 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. RANKL clearly holds the key to the osteolytic process. The cancer cells affect osteoblast morphology and extracellular matrix. Osteoblasts also produce osteoprotegerin (OPG), a decoy receptor to RANKL. The normal processes of bone resorption and formation are remarkably well balanced. Primer on the Metabolic Bone Diseases and Disorders of Mineral Metabolism. It's not the same as having cancer that starts in the bone. Part of The resorption phase of the process begins with recruitment of pre-osteoclasts that differentiate into activated osteoclasts under the direction of osteoblasts (Figure 1A). Radiol Clin North Am. Disclaimer, National Library of Medicine (B) Metastatic breast cancer cells in the bone microenvironment secrete parathyroid hormone-related protein (PTHrP), cytokines and growth factors that negatively impact osteoblast function. PloS one. 2006, 21: 1350-1358. 2007, 57: 43-66. Estrogen also increases osteoblast pro-collagen synthesis and decreases osteoblast apoptosis [63]. Here we discuss some of the proposed mechanisms that contribute to metastatic breast cancer-induced bone loss. Identification of a stimulator or protector of osteoblasts would be a major improvement in treatment for osteolytic breast cancer as well as other diseases of bone loss. 10.1158/0008-5472.CAN-10-2179. Cancer Treat Rev. government site. It improves the quality of life by preventing fractures but does not prolong life [73]. sharing sensitive information, make sure youre on a federal Continuing research into the mechanisms of cancer cell dormancy could result in a treatment that would prevent cancer cell proliferation in the bone and the chain of events that leads to osteolysis. Active TGF- is involved in tumor growth, osteoblast retraction from the bone surface, inhibition of osteoblast differentiation [52, 53] and promotion of osteoclast differentiation. 10.1007/s10585-006-9044-8. Bone. MeSH Matrix degradation appears to be only one of the roles of MMPs. For example, a hydroxyapatite scaold pre-loaded with bone morphogenetic protein-2 enhanced the growth rate of mammary tumor cells in the scaold [77]. 2010, 70: 6537-6547. Cathepsin K is the major mediator of bone resorption, controlling the osteoclast portion of the vicious cycle. Understanding the mechanisms of osteolysis should be the key to designing the cure. Fragments of human fetal bone implanted in SCID mice allow one to examine human cancer with human bone [76]. 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). 10.1016/j.rcl.2010.02.014. Lytic lesions are caused by cancer cells causing old bone to break down without new bone being . 2022 Aug 6;10(8):1908. doi: 10.3390/biomedicines10081908. This loss is more precipitous in women, due to the decrease in estrogen at menopause [3]. Recently, Roy and colleagues [69] investigated this association in a mouse model of autoimmune arthritis and found that arthritic mice had an increase in both lung and bone metastasis compared to the non-arthritic mice. In males, prostate and lung cancers make up 80% of carcinomas metastasizing to bone. This release of fluids and substances soon turns on the osteoblasts, which leads to the formation of new bone. Mol Cancer Ther. Clin Exp Metastasis. Survival Prediction in Patients Treated Surgically for Metastases of the Appendicular Skeleton-An External Validation of 2013-SPRING Model. Cancer. At the tissue level, PDGF is involved in bone formation, wound healing, erythropoiesis and angiogenesis as well as tumor growth and lesion development [57]. 10.1016/j.yexcr.2005.07.029. 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. 1999, London: Martin Dunitz Ltd. Raisz LG, Mundy GR, Luben RA: Skeletal reactions to neoplasms. 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]. Manage cookies/Do not sell my data we use in the preference centre. Cancer cells also can elicit an increase in osteoblast production of several other osteoclastogenic cytokines, such as monocyte chemotactic protein-1 (MCP-1) and IL-6, IL-8 and TNF [22]. Proff P, Romer P: The molecular mechanism behind bone remodelling: a review. 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. Because of its significant role, TGF- has been a tempting therapeutic target. Cancer Res. Bone. Adv Drug Deliv Rev.

Bone metastases from breast cancer are typically lytic, meaning that there is area of bone destruction at the site of metastasis. 10.1210/en.142.12.5050. American Society of Clinical Oncology Bisphosphonates Expert Panel. Other molecules made by multiple myeloma cells, such as IL-3, IL-7 and soluble frizzle-related protein-2, also inhibit osteoblast differentiation [27]. Breast cancer had the highest . Thus, bone loss is the result of excessive bone degradation and insufficient bone replacement. Metastasis of breast cancer cells to bone consists of multiple sequential steps. In the young adult, bone mass reaches its peak, but with increasing age there is a slow loss of mass. 10.1097/00003086-200004000-00013. 2010, 9: 122-10.1186/1476-4598-9-122. Osteomimetic factors driven by abnormal Runx2 activation in breast cancer cells may increase their survival in the bone microenvironment. Edited by: Rosen CL. All three doctors say that new, progressive pain in your bones or joints is the most common symptom of metastatic breast cancer in bones. 10.1158/1535-7163.MCT-08-0153.

Thus, the capacity of breast cancer cells to collaborate with osteoclasts is likely to be specific and is likely critical for them to cause osteolytic bone metastases. 2003, 349: 2483-2494. MMPs are involved in the bone remodeling process after osteoclasts are finished. eCollection 2022. 2005, 208: 194-206. Article Edited by: Rosen CL. 10.1111/j.0105-2896.2005.00326.x. J Bone Oncol. 10.1016/S0006-291X(02)02937-6. (A) The bone remodeling unit consists of osteoblasts, which produce osteoid, bone matrix, and osteoclasts, which degrade mineralized bone. Brook N, Brook E, Dharmarajan A, Dass CR, Chan A. Int J Biochem Cell Biol. Clinical Characteristics, Prognostic Factors and Treatment Outcomes of Patients with Bone-Only Metastatic Breast Cancer. For females, breast and lung are the most common primary sites ; nearly 80% of cancers that spread to the skeleton are from these locations. PubMed Several of these molecules are related to the recruitment and differentiation of osteoclasts; some are prominent players in the vicious cycle. The MMP family, composed of more than 20 members, can collectively degrade all components of the extracelluar matrix. Epub 2015 Dec 4. American Society of Clinical Oncology guideline on the role of bisphosphonates in breast cancer. 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. The bone remodeling microenvironment is a complex system in which the cell functions are controlled by multifunctional transcription factors, cytokines and growth factors. Google Scholar.

Osteocytes may act as mechanosensing cells and initiate the process when microfractures and loading are involved. However, once bone metastasis has occurred, the aim has been to break the osteolytic cycle by targeting osteoclasts. Current treatments can improve bone density, decrease skeletal related events and ease bone pain, yet existing bone lesions do not heal. Mouse Models of Tumor Bone Metastasis and Invasion for Studying CCN Proteins. 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. PTHrP, one of many proteins controlled by Runx2, is a major effector in breast cancer bone metastasis progression and bone loss. Exp Oncol. Breast, prostate, and lung cancers represent the main sources of bone metastases, with prostate and lung cancers being most common in males and breast cancer being most common in females . Rucci N, Millimaggi D, Mari M, Del Fattore A, Bologna M, Teti A, Angelucci A, Dolo V: Receptor activator of NF-kappaB ligand enhances breast cancer-induced osteolytic lesions through upregulation of extracellular matrix metalloproteinase inducer/CD147.

Thus, bone loss is due to both increased activation of osteoclasts and suppression of osteoblasts. PubMed In addition, production of inflammatory cytokines (that is, IL-6, TNF-, M-CSF, IL-1) is suppressed by estrogen [64]. PMC 1984 Jun 8;224(4653):1113-5 2008, 34 (Suppl 1): S25-30. Bone is the most common site of metastasis for breast cancer. However, because TGF- plays a more global role in cell proliferation and differentiation, its utility as a therapeutic may be limited. 10.1038/clpt.2009.312. Along with colleagues and students she has focused particularly on the fate of osteoblasts in the metastatic bone environment. 10.1158/0008-5472.CAN-09-4092. (A) The bone microenvironment under conditions of normal bone remodeling; (B) and in the presence of osteolytic bone metastases. At higher doses they may in fact prevent osteoblast differentiation [30]. 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. 10.2741/S110.

Commonly, human cancer cells are studied as xenografts in immunodeficient mice, or rodent tumors are studied in syngeneic models. Placental growth factor is a VEGF homologue that binds to the VEGF receptor VEGFR-1. Once osteoclasts are activated, they degrade bone matrix through several proteolytic enzymes, including MMPs and cathepsin K. Although cathepsin K is the major bone resorbing protease, MMPs, which are secreted by many cells, may be the 'master regulator' of the entire mechanism. 10.1016/j.ctrv.2008.03.008. Osteocytes are terminally differentiated osteoblasts that become embedded in the bone matrix at the end of the deposition phase of remodeling. For females, breast and lung are the most common primary sites ; nearly 80% of cancers that spread to the skeleton are from these locations. Metastases leading to overall bone loss are classified as osteolytic. 10.1007/s00784-009-0268-2. It is now generally accepted that the bone microenvironment is critical to the colonization and growth or dormancy of metastases. While some of the growth factors produced by breast and prostate cancers may be different, ultimately they engage the bone re-modeling process. 2010, 70: 1835-1844. Clements ME, Holtslander L, Edwards C, Todd V, Dooyema SDR, Bullock K, Bergdorf K, Zahnow CA, Connolly RM, Johnson RW. Clin Oral Investig. Their multifunctionality demonstrates their importance.

Development of clinically relevant in vivo metastasis models using human bone discs and breast cancer patient-derived xenografts. It is estimated that osteolytic lesions occur in 60 to 95% of myeloma patients [1, 27]. 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. Runx2 also promotes PTHrP expression in breast cancer cells, which in turn stimulates other cells, such as osteoblasts, to produce more RANKL, leading to further osteoclast activation. The mean standardized uptake value (SUV) for tumor was 7.1 versus 2.1 for benign lesions. Current therapeutic targets are indicated in green. 2021 Dec 1;31:100407. doi: 10.1016/j.jbo.2021.100407.

The use of blocking antibodies to placental growth factor in two xenograft mouse/human models greatly decreased the numbers and size of osteolytic lesions [61]. Many metastatic breast cancer cell lines have been found to also secrete PDGF, which has a strong impact on osteoblast development. Treatment can be tailored for each patient and, often requires multiple therapeutic interventions. 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. Federal government websites often end in .gov or .mil. It inhibits the differentiation of osteoclasts by competitive binding with RANKL. Pharmaceuticals. J Dent Res. While there is evidence that the breast cancer cell matrix metalloproteinases (MMPs) can resorb bone in vitro and contribute to bone degradation in vivo [5], it is now well accepted that osteoclasts are largely responsible for osteolytic metastatic lesions [6]. Bone provides support and protects vital organs but also is a metabolically active tissue. The roles of cell adhesion molecules including cadherins and laminin and matrix metalloproteinases in the development of osteolytic bone metastases by breast cancer are also discussed. Akech and colleagues [34] recently reported that Runx2 (Runt-related transcription factor 2) is produced by the highly metastatic prostate cancer cell PC-3, and positively correlates to the severity of osteolytic disease. Osteoclasts derive from mononuclear myeloid precursors that fuse to form pre-osteoclasts. Breast cancer metastasis to the bone: mechanisms of bone loss, http://breast-cancer-research.com/series/metastasis_pathway. Before NF-B/MAP-kinase inhibitors (SN50, PD98059 and SB203580), COX-2 inhibitors (indomethacin) and EP4 receptor decoy [46] all result in a down-regulation of RANKL production and a concomitant decrease in osteoclastogenesis. Breast cancer is often compared with prostate cancer, which metastasizes to the skeleton with a similar frequency. Clipboard, Search History, and several other advanced features are temporarily unavailable. volume12, Articlenumber:215 (2010) 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. Clinical evidence indicates that this drug can reduce the rate of bone loss, but is not curative. Cells of the monocyte-macrophage lineage are stimulated to form osteoclast progenitor cells. Skeletal metastases in breast carcinoma: classic patterns of treatment response Hemonc Today | This case focuses on a 51-year-old woman with a history of right breast cancer initially. PubMed These types of tumors are called osteolytic, or simply lytic. 10.1111/j.1749-6632.1974.tb14480.x. SPARC cleavage also coincides with an increase in inflammatory cytokines such as IL-6 and IL-8 [51]. Lynch CC: Matrix metalloproteinases as master regulators of the vicious cycle of bone metastasis. FOIA The tumors that develop, sometimes called lesions, can: Make the bones weaker and less dense. As might be expected from the nature of the osteolytic process, that is, the degradation of bone, the microenvironment contains many proteases. J Biomol Tech. 10.3816/CBC.2005.s.004. 10.1016/j.ctrv.2010.04.003. Bone metastasis significantly affects both quality of life and survival of the breast cancer patient.

Cortical bone provides strength and protection while trabecular bone is the most metabolically active. Clohisy DR, Perkins SL, Ramnaraine ML: Review of cellular mechanisms of tumor osteolysis. In the late 1980 s, PTHrP was linked to hypercalcemia in several cancers, providing evidence that PTHrP was involved in bone resorption. Of the many prostaglandins, PGE2 is known to play a critical role in cancer progression. Methods Mol Biol. Often, bone metastases have both lytic and blastic features. 1988 Jun;7(2):143-88 However, both drugs are associated with low incidence of osteonecrosis of the jaw [75]. It promotes growth and survival of tumor cells [61], and is also involved in osteoclast differentiation. In advanced disease, bone formation is essentially absent, and the processes of bone resorption and formation become uncoupled. On x-rays, these metastases show up as spots that are whiter than the bone around them. Khosla S: Minireview: the OPG/RANKL/RANK system. Bone metastasis significantly affects both quality of life and survival of the breast cancer patient. 2023;2582:343-353. doi: 10.1007/978-1-0716-2744-0_24. PubMed [Management of bone metastases from breast cancer]. 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]. Using this device, we have been able to grow osteoblasts into a mineralized tissue. 2003, 33: 28-37. McHayleh W, Ellerman J, Roodman D: Hematologic malignancies and bone. Below are the links to the authors original submitted files for images. Am J Clin Oncol. In normal bone remodeling, osteoclasts secrete PDGF, which acts as a chemoattractant to recruit pre-osteoblasts to the site of bone repair [58]. blastic (bone formation), or mixed lesions (Fig 2). Biochem Biophys Res Commun. According to this paradigm, the tumor cells produce a variety of growth factors, most notably parathyroid hormone-related protein (PTHrP) [18]. These molecules not only help support tumor cells, but also are osteoclastogenic. PTH/PTHrP, TNF-, prostaglandins (PGE2), IL-1, IL-11, FGF-2, and IGF-1 have been reported to increase RANKL production. Clin Adv Hematol Oncol. Bisphosphonates such as zoledronic acid (Zoledronate) bind to hydroxyapatite of the bone matrix and are ingested by osteoclasts, which then undergo apoptosis. Ohshiba T, Miyaura C, Ito A: Role of prostaglandin E produced by osteoblasts in osteolysis due to bone metastasis. There are 5 tumors notorious for their capacity to spread to bone that include Breast, Lung, Thyroid, Renal Cell and Prostate (a popular memory aid is BLT Kosher Pickle.) Keywords: 2009, 69: 4097-4100. 2006, 23: 345-356. Clinically, complications secondary to bone metastasis include pain, pathologic fractures, spinal cord compression, and hypercalcemia of malignancy. These functional molecules complete the cycle and osteolysis continues. In reality the system is much more complex (Table 1). Bone metastasis may be the first sign that you have cancer, or bone metastasis may occur years after cancer treatment. 2009, 11: R56-10.1186/bcr2345. Cancer Res. Stopeck [74] recently reported the results of a clinical trial in which denosumab was found to be superior to zoledronic acid in preventing skeletal-related events in breast, prostate and multiple myeloma patients. 2008, 7: 2807-2816. This increase in COX-2 results in increased secretion of PGE2, which binds to EP4 receptors on the surface of the osteoblasts. The PGE2-mediated production of RANKL induces osteoclastogenesis via RANK. 2010, 48: 483-495. A delicate balance of the bone-forming osteoblasts and bone-resorbing osteoclasts in the dynamic microenvironment of the skeleton maintains normal bone remodeling and integrity. While EMMPRIN is produced normally during tissue remodeling, it increases during tumor progression and metastasis. Juarez P, Guise TA: TGF-beta in cancer and bone: Implications for treatment of bone metastases. Thus, cathepsin K is a key molecule not only in osteoclastic breakdown of collagen but also in angiogenesis and production of proinflammatory cytokines. Lerner UH: Bone remodeling in post-menopausal osteoporosis. 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. Due to this, the bones get harder and cause the condition called sclerosis. Primarily they spread to spine, but lung cancer is known to metastasize to the . 2005, 10: 169-180. 2008, 314: 173-183. Osteo-blasts also produce osteoprotegerin (OPG), a decoy receptor to RANKL that curtails osteoclast activation. 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. 2008, 3: e3537-10.1371/journal.pone.0003537.

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 . Thus, inflammation is likely to be important in cancer initiation, metastasis and the resulting osteolysis. Recently, we have found that metastatic breast cancer cells have profound effects on osteoblasts in culture [22] and in animals [31, 32]. 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. It is common to find increased PTHrP serum levels in breast cancer patients. 2006, 85: 596-607. Bone Rep. 2022 Jun 12;17:101597. doi: 10.1016/j.bonr.2022.101597. Cancer.
