breast cancer bone metastasis lytic or blastic

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. government site. Thus, inflammation is likely to be important in cancer initiation, metastasis and the resulting osteolysis. HDAC inhibitors induce LIFR expression and promote a dormancy phenotype in breast cancer. Epub 2021 Jul 10. PTHrP, one of many proteins controlled by Runx2, is a major effector in breast cancer bone metastasis progression and bone loss. Survival Prediction in Patients Treated Surgically for Metastases of the Appendicular Skeleton-An External Validation of 2013-SPRING Model. 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 ]. 10.1016/S8756-3282(03)00086-3. 2006, 21: 1350-1358.

Brook N, Brook E, Dharmarajan A, Dass CR, Chan A. Int J Biochem Cell Biol. American Society of Clinical Oncology guideline on the role of bisphosphonates in breast cancer. The results of an in vivo study showed that OPN-deficient mice showed significantly reduced bone metastasis [38]. Careers. Lung cancer is the third most common site of origin of metastatic cancer deposits in bone, after breast and prostate cancer. There is evidence that bisphosphonates also contribute to tumor cell death, especially in combination with chemotherapy [72]. Clezardin P, Teti A: Bone metastasis: pathogenesis and therapeutic implications. Google Scholar. 2008, 314: 173-183.

Eventually, bone remodeling ceases as both osteoblasts and osteoclasts are lost. 10.1056/NEJMoa030847. HHS Vulnerability Disclosure, Help 2010, 126: 1749-1760. One of its substrates is SPARC (secreted protein acidic and rich in cysteine; osteonectin/BM-40) [51]. Kubota K, Sakikawa C, Katsumata M, Nakamura T, Wakabayashi K: PDGF BB purified from osteoclasts acts as osteoblastogenesis inhibitory factor (OBIF). PGs produced from this arachidonic acid conversion are both autocrine and paracrine factors that help to govern physiologic homeostasis. 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. 2021 Dec 1;31:100407. doi: 10.1016/j.jbo.2021.100407. 10.1038/sj.bjc.6602417. Standal T, Borset M, Sundan A: Role of osteopontin in adhesion, migration, cell survival and bone remodeling. The bone microenvironment. 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. Administration of bisphosphonates may slow osteolytic lesion progression and stabilize or increase overall bone density, but does not bring about healing [1, 16, 26]. Brown JE, Thomson CS, Ellis SP, Gutcher SA, Purohit OP, Coleman RE: Bone resorption predicts for skeletal complications in metastatic bone disease.

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. Thus, bone loss is the result of excessive bone degradation and insufficient bone replacement. Bethesda, MD 20894, Web Policies Zambonin Zallone A, Teti A, Primavera MV: Resorption of vital or devitalized bone by isolated osteoclasts in vitro. Those leading to excess bone deposition are considered osteoblastic. 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. In reality the system is much more complex (Table 1). 2002, 13: 62-71. Where do the MMPs come from? The cancer cells affect osteoblast morphology and extracellular matrix. official website and that any information you provide is encrypted 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. The .gov means its official. 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]. CAS The majority of breast cancer metastases ultimately cause bone loss. However, both drugs are associated with low incidence of osteonecrosis of the jaw [75]. For females, breast and lung are the most common primary sites ; nearly 80% of cancers that spread to the skeleton are from these locations. 2008, Washington, DC: American Society for Bone and Mineral Research, 374-378. full_text. Recent research has revealed how cancer cell Runx2 affects other cells in the bone microenvironment and promotes osteolysis. In contrast to breast cancer, prostate bone metastasis often results in osteoblastic lesions. 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. This approach will allow testing of components and drugs in a model less complex than an animal but more relevant than standard tissue culture. 10.1016/j.ctrv.2008.03.008. 2007, 57: 43-66. Despite the role of the osteoclasts in this process, the outcome is due in large part to the impact of cancer cells directly and indirectly on osteoblasts. Surprisingly, this treatment did not affect angiogenesis in the bone. Several MMPs (MMP2, 3, 9) can release TGF- from the latent state, allowing it to become active. Along with colleagues and students she has focused particularly on the fate of osteoblasts in the metastatic bone environment. Smolle MA, Musser E, Bergovec M, Friesenbichler J, Wibmer CL, Leitner L, Srensen MS, Petersen MM, Brcic I, Szkandera J, Scheipl S, Leithner A. Bone lining cells appear microscopically as relatively undifferentiated cells that line the bone. Edited by: Rosen CL. The dynamics of this system are interrupted when metastatic breast cancer cells are introduced, adding another layer of active molecules to the bone environment. 10.1007/s00784-009-0268-2. Federal government websites often end in .gov or .mil. J Dent Res. 2008, 3: e3537-10.1371/journal.pone.0003537. At least three major growth factors sequestered in the matrix are activated by MMPs. Bone is the most common site of metastasis for breast cancer. 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. Clin Adv Hematol Oncol. J Dent Res. Aldridge SE, Lennard TW, Williams JR, Birch MA: Vascular endothelial growth factor acts as an osteolytic factor in breast cancer metastases to bone. Cancer. Am J Clin Oncol. Clin Cancer Res. Chemotherapy may bring about ovarian failure and premature menopause [1]. IL-11, normally produced by bone marrow stromal cells and osteoblasts, is an important regulator of hematopoiesis and a potent promoter of osteoclast formation. Since the discovery of RANKL and its role in bone remodeling, the field of bone metastasis has moved rapidly. J Mammary Gland Biol Neoplasia. 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 metastases in breast cancer may be osteolytic, osteoblastic, or mixed blastic and lytic. The majority of bone metastases are asymptomatic. 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 . Curr Opin Support Palliat Care. 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. Corisdeo S, Gyda M, Zaidi M, Moonga BS, Troen BR: New insights into the regulation of cathepsin K gene expression by osteoprotegerin ligand. N Engl J Med. 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. 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]. 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). The other 20% of primary disease sites in both sexes are: kidney, thyroid, gastrointestinal tract and other locations. eCollection 2022 Dec. Edwards CM, Clements ME, Vecchi LA 3rd, Johnson JA, Johnson RW. However, because TGF- plays a more global role in cell proliferation and differentiation, its utility as a therapeutic may be limited. Recently, we have found that metastatic breast cancer cells have profound effects on osteoblasts in culture [22] and in animals [31, 32]. Angiogenesis inhibitor TNP-470 inhibits human breast cancer osteolytic bone metastasis in nude mice through the reduction of bone resorption. An Open Label, Phase Ib, Dose-escalation Study Evaluating the Safety and Tolerability of Xentuzumab and Abemaciclib in Patients With Locally Advanced or Metastatic Solid Tumours and in Combination With Endocrine Therapy in Patients With Locally Advanced o. 7. Cancer cells, osteoblasts, osteoclasts and endothelial cells produce MMPs. As seen in the images here, multiple, confluent sclerotic, blastic bony lesions are typical of metastatic breast cancer. 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. Please enable it to take advantage of the complete set of features! Part of this uncertainty is because we do not fully understand all of the cell, cytokine and growth factor interactions that occur in the bone microenvironment. 2001, 142: 5050-5055. Dysfunctional Runx2 results in the developmental arrest of osteoblasts and inhibition of osteogenesis. 1970, 86: 1436-1440. Induction of aberrant osteoclastogenesis is only part of the equation. Several of these molecules are related to the recruitment and differentiation of osteoclasts; some are prominent players in the vicious cycle. Bookshelf Google Scholar. As might be expected from the nature of the osteolytic process, that is, the degradation of bone, the microenvironment contains many proteases. These drugs may also cause cancer cell death; however, they may also negatively affect osteoblasts. In a recent comprehensive review article, Lynch [50] presents the case that they are 'master regulators' of the vicious cycle. Nevertheless, they do not appear to function in the osteoclast resorption lacuna, probably due to the low pH in this compartment. Cancer Res. 1974, 230: 473-475. 1984 Jun 8;224(4653):1113-5 10.1016/S0531-5565(03)00069-X. Unable to load your collection due to an error, Unable to load your delegates due to an error. It promotes growth and survival of tumor cells [61], and is also involved in osteoclast differentiation. 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. MMP1, 2, 3 process the binding factors and free IGF, allowing it to bind to its receptors found both on osteoblasts and osteoclasts. 2005, 5 (Suppl): S46-53. Breast cancer-derived factors facilitate osteolytic bone metastasis. Kang JS, Alliston T, Delston R, Derynck R: Repression of Runx2 function by TGF-beta through recruitment of class II histone deacetylases by Smad3. Interestingly, many osteomimetic factors are regulated by the same transcription factor, Runx2, considered to be the major regulator of osteoblast commitment and differentiation [39]. 2000 Mar;18(6):1378-91. doi: 10.1200/JCO.2000.18.6.1378. It's not the same as having cancer that starts in the bone. Cathepsin K is the major mediator of bone resorption, controlling the osteoclast portion of the vicious cycle. The clinical outcomes of bone pain, pathologic fractures, nerve compression syndrome, and metabolic disturbances leading to hypercalcemia and acid/base imbalance severely reduce the quality of life [3]. Metastasis of breast cancer cells to bone consists of multiple sequential steps. 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]. This loss is more precipitous in women, due to the decrease in estrogen at menopause [3]. 10.1016/S0006-291X(02)02937-6. Clarke BL, Khosla S: Physiology of bone loss. 2003, 38: 605-614. 2009, 7 (Suppl 7): S1-29. 2010, 36: 615-620. 2010. 2010, 8: 159-160. Because of its significant role, TGF- has been a tempting therapeutic target. 1999, 59: 1987-1993. Clinically, complications secondary to bone metastasis include pain, pathologic fractures, spinal cord compression, and hypercalcemia of malignancy. Immunol Rev. 2010, 3: 572-599. Estrogen profoundly affects bone remodeling by suppressing production of RANKL while increasing production of OPG. Metastatic breast cancer cells tend to spread to the bones more often than they do to other parts of the body. This process is effected by osteoblasts and osteoclasts within a functional and anatomic unit known as the basic multicellular unit (BMU). 2. Estrogen has also been shown to promote osteoclast apoptosis and inhibit activation of mature osteoclasts. MMP-9 is important in the cascade leading to activation of VEGFA. Myeloma cells may also produce RANKL and directly affect osteoclasts [28]. It's the most advanced stage of breast cancer. 2009, 13: 355-362. In addition, factors such as TGF- and IGFs that are released from the bone matrix during degradation serve to increase PTHrP expression in breast cancer cells. 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. This article is part of a review series on New pathways of metastasis, edited by Lewis Chodosh. Primer on the Metabolic Bone Diseases and Disorders of Mineral Metabolism. 2003, 33: 28-37. Thus, the ratio of RANKL to OPG is critical for osteoclast activation. IGF binding proteins keep this molecule latent. 10.1177/154405910608500703. Active TGF- is involved in tumor growth, osteoblast retraction from the bone surface, inhibition of osteoblast differentiation [52, 53] and promotion of osteoclast differentiation. J Cell Biochem. 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]. 2000, 373: 104-114. 2022 Jul 20;14(14):3521. doi: 10.3390/cancers14143521. Bone metastasis can occur in any bone but more commonly occurs in the spine, pelvis and thigh. Several of these RANKL inducers merit further discussion with respect to metastatic breast cancer-induced osteolysis. Nemeth JA, Harb JF, Barroso U, He Z, Grignon DJ, Cher ML: Severe combined immunodeficient-hu model of human prostate cancer metastasis to human bone. Arch Biochem Biophys. PubMedGoogle Scholar. FOIA 10.1158/0008-5472.CAN-10-2179. While EMMPRIN is produced normally during tissue remodeling, it increases during tumor progression and metastasis. 10.1359/jbmr.060610. 2009, 175: 1255-1269. The resorption phase of the process begins with recruitment of pre-osteoclasts that differentiate into activated osteoclasts under the direction of osteoblasts (Figure 1A). Osteoblast differentiation is suppressed; new osteoid production is no longer able to keep pace with bone resorption. 2003, 3: 537-549. 10.1038/clpt.2009.312.

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. Br J Cancer. This molecule is also produced by metastatic breast cancer cells [49]. sharing sensitive information, make sure youre on a federal The changes in the bone microenvironment then create a vicious cycle that further promotes bone destruction and tumor progression.Various therapeutic options are available for bone metastases of breast cancer. Adv Drug Deliv Rev. Int J Cancer. They activate latent molecules released from the matrix. Other molecules made by multiple myeloma cells, such as IL-3, IL-7 and soluble frizzle-related protein-2, also inhibit osteoblast differentiation [27]. Blood. PMC Proff P, Romer P: The molecular mechanism behind bone remodelling: a review. According to this paradigm, the tumor cells produce a variety of growth factors, most notably parathyroid hormone-related protein (PTHrP) [18]. However, both bone degradation and deposition likely occur early in the metastatic process. 2007, 6: 2609-2617. The receptor binding activity in turn causes an increase in production of RANKL. In advanced disease, bone formation is essentially absent, and the processes of bone resorption and formation become uncoupled. Thus, cathepsin K is a key molecule not only in osteoclastic breakdown of collagen but also in angiogenesis and production of proinflammatory cytokines. These molecules not only help support tumor cells, but also are osteoclastogenic. Heterogeneity of tumor cells in the bone microenvironment: Mechanisms and therapeutic targets for bone metastasis of prostate or breast cancer. Cancer Treat Rev. It is now known that PGE2 signaling through its receptor EP4 plays a crucial role in osteolysis by inducing monocytes to form mature osteoclasts. 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. Commonly used modalities include local therapies such as surgery, radiation therapy and radiofrequency ablation (RFA) together with systemic therapies such as endocrine therapy, chemotherapy, monoclonal antibody-based therapy, bone-enhancing therapy and radioisotope therapy.

Breast cancer bone metastases: pathogenesis and therapeutic targets. 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. By knowing the typical behavior of the metastatic lesion - lytic or blastic - you can help sort between the types to make the mnemonic even more useful. However, the process is described in brief in order to further consider the mechanisms of osteolytic metastasis. While not directly responsible for osteolysis in metastatic breast cancer disease, there are physiological parameters that can amplify the degree of bone loss. It can activate both Smad-dependent and Smad-independent signal pathways to induce preosteolytic factors such as PTHrP [23]. 2008, 34 (Suppl 1): S25-30. Cancer Res. 2010. Clin Pharmacol Ther.

Metastatic bone lesions are the predominant malignancy to effect bone, with 15 times the occurrence rate of the next most common bone malignancy. Teriparatide, in contrast to bisphosphonates and denosumab, acts on osteoblasts to stimulate bone formation. RANKL clearly holds the key to the osteolytic process. Bone is the most common site of metastasis for breast cancer. 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]. Mouse Models of Tumor Bone Metastasis and Invasion for Studying CCN Proteins. However, PTHrP does not directly stimulate osteoclast differentiation, but rather stimulates other cells to increase RANKL and decrease OPG production.
