breast cancer bone metastasis lytic or blastic

Breast Cancer Res. Other cells of the osteoblastic lineage include bone lining cells and osteocytes. 10.1111/j.0105-2896.2005.00326.x. Ohshiba T, Miyaura C, Ito A: Role of prostaglandin E produced by osteoblasts in osteolysis due to bone metastasis. 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. CAS Placental growth factor is a VEGF homologue that binds to the VEGF receptor VEGFR-1. Osteolytic lesions are the end result of osteoclast activity; however, osteoclast differentiation and activation are mediated by osteoblast production of RANKL (receptor activator for NFB ligand) and several osteoclastogenic cytokines. The site is secure. Using this device, we have been able to grow osteoblasts into a mineralized tissue. Corisdeo S, Gyda M, Zaidi M, Moonga BS, Troen BR: New insights into the regulation of cathepsin K gene expression by osteoprotegerin ligand. We are in the process of adding osteoclasts to the system to create a rudimentary in vitro bone remodeling unit. In advanced disease, bone formation is essentially absent, and the processes of bone resorption and formation become uncoupled. Bone. In the next step, preosteoblasts are recruited from the mesenchymal stem cell population and differentiate into osteoblasts. Denosumab (Prolia), the latest drug to enter the field, is a monoclonal antibody to RANKL. Metastasis of breast cancer cells to bone consists of multiple sequential steps. Rodrguez-Toms E, Arenas M, Baiges-Gaya G, Acosta J, Araguas P, Malave B, Casta H, Jimnez-Franco A, Benavides-Villarreal R, Sabater S, Sol-Alberich R, Camps J, Joven J. Antioxidants (Basel). This feature accounts for the variable sensitivity and specificity of different imaging modalities. Cells of the monocyte-macrophage lineage are stimulated to form osteoclast progenitor cells. However, teriparatide is associated with an increased risk of osteosarcoma and exacerbation of skeletal metastases because of its effect on bone turnover [75]. Parathyroid hormone-related protein and bone metastases. Cathepsin K is believed to be the major protease in this capacity. This process is effected by osteoblasts and osteoclasts within a functional and anatomic unit known as the basic multicellular unit (BMU). The .gov means its official. 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. In this context, RANKL increases in the presence of inflammatory agents from infectious organisms, such as lipopolysaccharide, CpGpDNA and viral double-stranded DNA [41]. Osteomimetic factors driven by abnormal Runx2 activation in breast cancer cells may increase their survival in the bone microenvironment. Thus, in the course of the osteolytic process, the osteoblasts are unable to fulfill their role as bone building cells. Metastatic bone lesions are the predominant malignancy to effect bone, with 15 times the occurrence rate of the next most common bone malignancy. Epidemiological studies have also correlated the increase in breast cancer rates with decreasing sunlight exposure. Grey A: Teriparatide for bone loss in the jaw. Br J Cancer. Its common for people to have lytic and blastic lesions at the same time. 10.1006/bbrc.2001.5127. Bone Rep. 2022 Jun 12;17:101597. doi: 10.1016/j.bonr.2022.101597. Breast cancer bone metastases: pathogenesis and therapeutic targets. Cancer Res. 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. Breast Cancer Research 10.1038/clpt.2009.312. In doing so, cancer cells are equipped to home, adhere, survive and proliferate in the bone microenvironment. What Are The Symptoms Of Bone Metastasis In Breast Cancer. Several MMPs (MMP2, 3, 9) can release TGF- from the latent state, allowing it to become active. 10.1002/(SICI)1097-0142(19971015)80:8+<1572::AID-CNCR7>3.0.CO;2-M. Karaplis AC, Goltzman D: PTH and PTHrP effects on the skeleton. Hillner BE, Ingle JN, Berenson JR, Janjan NA, Albain KS, Lipton A, Yee G, Biermann JS, Chlebowski RT, Pfister DG. RANKL clearly holds the key to the osteolytic process. Unfortunately, some of the therapies used for breast cancer patients may exacerbate the problem. 10.1210/endo-86-6-1436. 2023 BioMed Central Ltd unless otherwise stated. This loss is more precipitous in women, due to the decrease in estrogen at menopause [3]. Development of clinically relevant in vivo metastasis models using human bone discs and breast cancer patient-derived xenografts. Radiol Clin North Am. 2003, 33: 28-37. Blood. 7, Chapter 8600 Rockville Pike At least three major growth factors sequestered in the matrix are activated by MMPs. RANKL and other pro-osteoclastogenic cytokines are increased with a concomitant reduction in OPG, resulting in more osteoclast formation and bone degradation. 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. Osteomimetic factors include osteopontin (OPN), osteocalcin, osteonectin, bone sialoprotein, RANKL and PTHrP. While EMMPRIN is produced normally during tissue remodeling, it increases during tumor progression and metastasis. It binds to two class III tyrosine kinase receptors, PDGFR and PDGFR, leading to activation of several signaling molecules. Purpose: This is a study in adult patients with different types of cancer. -. Takahashi T, Uehara H, Bando Y, Izumi K: Soluble EP2 neutralizes prostaglandin E2-induced cell signaling and inhibits osteolytic tumor growth. It's not the same as having cancer that starts in the bone. 2010, 87: 401-406.

Shimo T, Okui T, Horie N, Yokozeki K, Takigawa M, Sasaki A. However, once bone metastasis has occurred, the aim has been to break the osteolytic cycle by targeting osteoclasts. Orr and colleagues [5] have determined MMPs sufficient to resorb bone in vitro and to contribute to the process in vivo. The PGE2-mediated production of RANKL induces osteoclastogenesis via RANK. It has also been suggested that Runx2 is ectopically expressed in bone-destined metastatic breast cancer cells. 10.1056/NEJMe1010459. 2007, 67: 9542-9548. 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. 2003, 89: 2031-2037. Due to this, the bones get harder and cause the condition called sclerosis. 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. We also discuss known risk factors as well as detection and assessment of bone metastases. 10.1038/sj.emboj.7600729. Am J Pathol. The bone microenvironment. 2010. 2008, 3: e3537-10.1371/journal.pone.0003537. Clin Adv Hematol Oncol. 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. Home; Study Search; Study Details From Other Databases Clin Oral Investig. government site. Breast cancer is often compared with prostate cancer, which metastasizes to the skeleton with a similar frequency. The dynamics of this system are interrupted when metastatic breast cancer cells are introduced, adding another layer of active molecules to the bone environment. Cancer. Front Biosci (Schol Ed). 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. Bone is the most common site of metastasis for breast cancer. Ann N Y Acad Sci. In the young adult, bone mass reaches its peak, but with increasing age there is a slow loss of mass. Evolving cancer-niche interactions and therapeutic targets during bone metastasis. Retrieval of the bone at specific times gives a snapshot of the status of metastases. Zambonin Zallone A, Teti A, Primavera MV: Resorption of vital or devitalized bone by isolated osteoclasts in vitro. While some of the growth factors produced by breast and prostate cancers may be different, ultimately they engage the bone re-modeling process. What initiates remodeling in the non-tumor-containing bone? quiz S30, CAS PTHrP, one of many proteins controlled by Runx2, is a major effector in breast cancer bone metastasis progression and bone loss. Verbruggen ASK, McCarthy EC, Dwyer RM, McNamara LM. While the outcome is predominantly osteoblastic, it is known that prostate cancer lesions display both blastic and lytic characteristics early in the process. 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. PMC According to this paradigm, the tumor cells produce a variety of growth factors, most notably parathyroid hormone-related protein (PTHrP) [18]. Temporal and spatial changes in bone mineral content and mechanical properties during breast-cancer bone metastases. Breast cancer had the highest . Despite the use of various therapeutic modalities, bone metastases eventually become resistant to therapy, and disease progresses.In this chapter, we describe the clinical picture and biological mechanism of bone metastases in breast cancer. PubMed Central Andrea M Mastro. There are many suspected factors, such as microfractures, loss of mechanical loading, hormones, cytokines, calcium levels and inflammation. Annu Rev Pathol. Klein DC, Raisz LG: Prostaglandins: stimulation of bone resorption in tissue culture. It can contribute to tumor cell survival, proliferation, adhesion, and migration. IGF binding proteins keep this molecule latent. IL-8, a proinflammatory CXC chemokine, is secreted by monocytes, endothelial cells and osteoblasts. Lipton A: Emerging role of bisphosphonates in the clinic--antitumor activity and prevention of metastasis to 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]. 1993 Jun 1;90(11):5021-5 N Engl J Med. Osteoblastic or blastic metastases cause an area of the bone to look denser or sclerotic. Other molecules made by multiple myeloma cells, such as IL-3, IL-7 and soluble frizzle-related protein-2, also inhibit osteoblast differentiation [27]. 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. AMM, the senior investigator and corresponding author, has worked in the area of breast cancer metastasis to bone for over 12 years. 2003, 300: 957-964. 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. In addition, pre-clinical trials with agents that target cathepsin K, certain matrix metalloproteinases (MMPs), and transforming growth factor (TGF)- are underway. 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.ctrv.2010.04.003. Clin Pharmacol Ther. 10.1210/en.142.12.5050. 2010, 29: 811-821. 10.1158/0008-5472.CAN-09-3194. Nat Cell Biol. 2008, 314: 173-183. However, because TGF- plays a more global role in cell proliferation and differentiation, its utility as a therapeutic may be limited. Manage cookies/Do not sell my data we use in the preference centre. prostate = blastic/sclerotic . 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. However, there is no guarantee that inhibition of osteolytic lesions would prevent the growth of cancer cells in the bone or their spread to other organs. 10.1196/annals.1365.035. Cancer Res. 10.1177/154405910608500703. Correspondence to 2010, [Epub ahead of print]. 7. Clinical evidence indicates that this drug can reduce the rate of bone loss, but is not curative. Clin Cancer Res. For example, a hydroxyapatite scaold pre-loaded with bone morphogenetic protein-2 enhanced the growth rate of mammary tumor cells in the scaold [77]. For example, OPN is produced by many breast cancer cells and has a strong clinical correlation with poor prognosis and decreased survival [37]. Administration of bisphosphonates may slow osteolytic lesion progression and stabilize or increase overall bone density, but does not bring about healing [1, 16, 26]. An official website of the United States government. Pratap and colleagues [40] found that Runx2 responds to TGF- stimulation by activating the expression of Indian hedgehog (IHH), which further increases the level of PTHrP. These results signify an important role for cancer cell-derived Runx2 in the osteolytic process. In a series of in vitro, ex vivo and in vivo experiments, Ohshiba and colleagues [45] demonstrated that direct cell-cell contact between breast cancer cells and osteoblasts caused an increase in COX-2 expression in the osteoblasts due to activation of the NFB/mitogen-activated protein (MAP) kinase pathway. In the presence of cancer cells, osteoblasts increase expression of pro-inflammatory cytokines such as IL-6, monocyte chemotactic protein-1 (MCP-1), macrophage inflammatory protein-2 (MIP-2; GRO alpha human), keratinocyte chemoattractant (KC; IL-8 human) and VEGF. Yang Y, Ren Y, Ramani VC, Nan L, Suva LJ, Sanderson RD: Heparanase enhances local and systemic osteolysis in multiple myeloma by upregulating the expression and secretion of RANKL. Cancer Res. Bisphosphonates binding to hydroxyapatite are ingested by osteoclasts and cause their apoptosis. It is now generally accepted that the bone microenvironment is critical to the colonization and growth or dormancy of metastases. Osteo-blasts also produce osteoprotegerin (OPG), a decoy receptor to RANKL that curtails osteoclast activation. Stopeck A: Denosumab findings in metastatic breast cancer. 2009, 15: 5829-5839. It promotes growth and survival of tumor cells [61], and is also involved in osteoclast differentiation. Please enable it to take advantage of the complete set of features! 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 . MeSH However, 15-20% of metastatic breast cancer lesions can be blastic or mixed. Powles TJ, Clark SA, Easty DM, Easty GC, Neville AM: The inhibition by aspirin and indomethacin of osteolytic tumor deposits and hypercalcaemia in rats with Walker tumour, and its possible application to human breast cancer. Bone metastasis can occur in any bone but more commonly occurs in the spine, pelvis and thigh. It was recently reported that mice deficient in vitamin D or calcium showed increased metastatic tumor growth and accelerated rates of bone resorption [66, 67]. Ann N Y Acad Sci. While ductal carcinoma in situ detected early is 98% curable, bone metastases are basically incurable [2]. Int J Cancer. Google Scholar. 10.1016/j.ctrv.2008.03.008. Arch Biochem Biophys. Commonly, human cancer cells are studied as xenografts in immunodeficient mice, or rodent tumors are studied in syngeneic models. It is estimated that 85% of individuals with advanced disease harbor bone metastases [1]. In the final stages of metastatic osteolytic breast cancer disease, the cancer cells, fueled by growth factors released from the degraded matrix, expand unchecked. A thorough review of bone remodeling is beyond the scope of this article, and there are several excellent, recent reviews [8, 9]. 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. Epub 2018 Jan 5. The majority of breast cancer metastases ultimately cause bone loss. Primer on the Metabolic Bone Diseases and Disorders of Mineral Metabolism. 2001, 285: 335-339. Several of these RANKL inducers merit further discussion with respect to metastatic breast cancer-induced osteolysis. Recently we have begun developing an in vitro bioreactor [78]. 10.1016/j.abb.2008.02.030. It's the most advanced stage of breast cancer. 1974, 230: 473-475. Among these are the MMPs. MMP-9 is important in the cascade leading to activation of VEGFA. Of the bisphosphonates, zoledronic acid is the most potent. However, PTHrP does not directly stimulate osteoclast differentiation, but rather stimulates other cells to increase RANKL and decrease OPG production. 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.) Even in adults it is estimated that about 10% of the bone is renewed each year [7]. 2005, 5 (Suppl): S46-53. Eventually, bone remodeling ceases as both osteoblasts and osteoclasts are lost. Another growth factor sequestered in the matrix is IGF. Accessibility 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. Metastatic breast cancer cells tend to spread to the bones more often than they do to other parts of the body. Adv Drug Deliv Rev. 10.1359/jbmr.060610. These molecules cause osteoblasts not only to form new bone but also to release RANKL and other osteoclastic mediators. 2006, 23: 345-356. 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. statement and Article The MMP family, composed of more than 20 members, can collectively degrade all components of the extracelluar matrix. 2010, 363: 2458-2459. Feng X, McDonald JM: Disorders of bone remodeling. Cancer Treat Rev. Bone metastases may cause pain, may make the bones more susceptible to fractures, and may cause increased levels of calcium in the blood. However, this approach has not entirely solved the problem. Methods Mol Biol. 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]. 2019 Nov 29;21(1):130. doi: 10.1186/s13058-019-1220-2. Proff P, Romer P: The molecular mechanism behind bone remodelling: a review. J Clin Oncol. 2007, 24: 599-608. Studies with MMP9-null mice indicate its importance in tumor progression in ovarian cancer, prostate cancer and bone metastasis [56]. The mean standardized uptake value (SUV) for tumor was 7.1 versus 2.1 for benign lesions. Lee J, Weber M, Mejia S, Bone E, Watson P, Orr W: A matrix metalloproteinase inhibitor, batimastat, retards the development of osteolytic bone metastases by MDA-MB-231 human breast cancer cells in Balb C nu/nu mice. DMS is a senior research technician with many years experience in the bone field. Nevertheless, the inaccessibility, opacity and size of the skeleton make it difficult to study even in laboratory animals. Clezardin P, Teti A: Bone metastasis: pathogenesis and therapeutic implications. They activate latent molecules released from the matrix. Kingsley LA, Fournier PG, Chirgwin JM, Guise TA: Molecular biology of bone metastasis. Since the discovery of RANKL and its role in bone remodeling, the field of bone metastasis has moved rapidly. J Dent Res. HDAC inhibitors induce LIFR expression and promote a dormancy phenotype in breast cancer. 2003, 38: 605-614. Article Runx2 downregulates proliferation and induces p21, RANKL, MMP2, MMP9, MMP13, VEGF, OPN, bone sialoprotein and PTHrP protein expression to promote osteoblast differentiation, bone development and turnover [39]. At least three essential molecules, TGF-, IGF, and VEGF, need to be activated by MMPs before they can function. Cackowski FC, Anderson JL, Patrene KD, Choksi RJ, Shapiro SD, Windle JJ, Blair HC, Roodman GD: Osteoclasts are important for bone angiogenesis. Cancer Res. Juarez P, Guise TA: TGF-beta in cancer and bone: Implications for treatment of bone metastases. Drugs of the bisphosphonate family have been used for many years as the standard of care. As seen in the images here, multiple, confluent sclerotic, blastic bony lesions are typical of metastatic breast cancer. 10.1210/er.19.1.18. Along with colleagues and students she has focused particularly on the fate of osteoblasts in the metastatic bone environment. 2008, 7: 2807-2816. 2012 Aug;39(8):1174-7. A smoking history is almost always present. The results of an in vivo study showed that OPN-deficient mice showed significantly reduced bone metastasis [38]. 10.1016/S1535-6108(03)00132-6. These cells fuse to form multinucleated, but non-functional pre-osteoclasts. The skeleton is constantly undergoing remodeling. 10.1097/00003086-200004000-00013. Current therapies consist of blocking osteoclast activity as a means of disrupting the vicious cycle. Cancer cells, osteoblasts, osteoclasts and endothelial cells produce MMPs. They follow the osteoclasts, reforming the bone matrix. In this process, the older bone doesn't break down while the new bone forms. 2005, 24: 2543-2555. 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]. PTH/PTHrP, TNF-, prostaglandins (PGE2), IL-1, IL-11, FGF-2, and IGF-1 have been reported to increase RANKL production. PubMed PubMedGoogle Scholar. Matrix degradation appears to be only one of the roles of MMPs. MMPs are involved in the bone remodeling process after osteoclasts are finished. Osteoblast differentiation is suppressed; new osteoid production is no longer able to keep pace with bone resorption. Immunol Rev. Survival Prediction in Patients Treated Surgically for Metastases of the Appendicular Skeleton-An External Validation of 2013-SPRING Model. It can activate osteoclasts independent of RANKL [21]. Recent research has revealed how cancer cell Runx2 affects other cells in the bone microenvironment and promotes osteolysis. 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. 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. Gan To Kagaku Ryoho. On x-rays, these metastases show up as spots that are whiter than the bone around them. 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. Oncogene. Curr Opin Support Palliat Care. 10.1007/s10585-004-1867-6. Exp Cell Res. Bone. Their multifunctionality demonstrates their importance. It is estimated that osteolytic lesions occur in 60 to 95% of myeloma patients [1, 27]. Bone is the most common site of metastasis for breast cancer. Hadjidakis DJ, Androulakis II: Bone remodeling. Just as osteoblasts are a critical partner in normal bone remodeling, they are vital to the metastatic osteolytic process. While not directly responsible for osteolysis in metastatic breast cancer disease, there are physiological parameters that can amplify the degree of bone loss. Bookshelf eCollection 2022. Estrogen also increases osteoblast pro-collagen synthesis and decreases osteoblast apoptosis [63]. Of the many prostaglandins, PGE2 is known to play a critical role in cancer progression. Many metastatic breast cancer cell lines have been found to also secrete PDGF, which has a strong impact on osteoblast development. Google Scholar. Lerner UH: Inflammation-induced bone remodeling in periodontal disease and the influence of post-menopausal osteoporosis. 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]. 2007, 6: 2609-2617. The https:// ensures that you are connecting to the Osteoclasts derive from hematopoietic stem cells.
