Lerner UH: Bone remodeling in post-menopausal osteoporosis. MeSH PGs produced from this arachidonic acid conversion are both autocrine and paracrine factors that help to govern physiologic homeostasis. Because osteoblasts secrete both RANKL and OPG, they are major mediators of osteoclastogenesis [25]. Breast cancer frequently metastasizes to the skeleton, interrupting the normal bone remodeling process and causing bone degradation. The average survival after the diagnosis of a breast cancer metastasis to bone has dramatically . 2016 Apr 1;99(Pt B):206-211. doi: 10.1016/j.addr.2015.11.017.

Bone metastases from breast cancer are typically lytic, meaning that there is area of bone destruction at the site of metastasis. Edited by: Rosen CL. Cancer Treat Rev. PTH/PTHrP, TNF-, prostaglandins (PGE2), IL-1, IL-11, FGF-2, and IGF-1 have been reported to increase RANKL production. Larkins TL, Nowell M, Singh S, Sanford GL: Inhibition of cyclooxygenase-2 decreases breast cancer cell motility, invasion and matrix metalloproteinase expression. 2 Of interest is that patients with blastic (versus osteolytic) bone metastases have been reported to have prolonged survival. 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). 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. Bone metastases result in lesions or injury to the bone tissue. Bookshelf This loss is more precipitous in women, due to the decrease in estrogen at menopause [3].

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. Lytic lesions should have radiologic evidence of calcication . 10.1016/S0531-5565(03)00069-X. 2010, 29: 811-821. Their function is not clear except that their retraction is necessary for bone resorption to begin [10]. Recent research has revealed how cancer cell Runx2 affects other cells in the bone microenvironment and promotes osteolysis. Guise TA, Kozlow WM, Heras-Herzig A, Padalecki SS, Yin JJ, Chirgwin JM: Molecular mechanisms of breast cancer metastases to bone. Correspondence to Ganapathy and colleagues [24] found that TGF- antagonists are able to reduce bone metastasis and the number and activity of differentiated osteoclasts [24]. 2010. J Natl Compr Canc Netw. Article Of the bisphosphonates, zoledronic acid is the most potent. While some of the growth factors produced by breast and prostate cancers may be different, ultimately they engage the bone re-modeling process. Surprisingly, this treatment did not affect angiogenesis in the bone. Below are the links to the authors original submitted files for images. The presence of tumor cells in the bone microenvironment perturbs the balance between osteoblasts and osteoclasts, leading to excess bone loss or formation. 2010, 70: 8329-8338. 10.1158/1535-7163.MCT-07-0234.

As pointed out by Lynch, the spatial and temporal expression of these molecules is of utmost importance. The bone microenvironment. 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-derived factors facilitate osteolytic bone metastasis. Privacy 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.

Carlsten H: Immune responses and bone loss: the estrogen connection. We present therapeutic options for bone metastasis using a multidisciplinary approach. 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. Thus, inflammation is likely to be important in cancer initiation, metastasis and the resulting osteolysis. 3 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 . 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 . These capacities are essential for any cancer cells to develop distant metastases in organs such as lungs and liver as well as bone. 10.1038/sj.bjc.6602417. The role of lining cells. 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. 10.3390/ph3030572. Lipton A: Emerging role of bisphosphonates in the clinic--antitumor activity and prevention of metastasis to bone. 10.1016/S8756-3282(03)00086-3.

While not directly responsible for osteolysis in metastatic breast cancer disease, there are physiological parameters that can amplify the degree of bone loss. 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. Juarez P, Guise TA: TGF-beta in cancer and bone: Implications for treatment of bone metastases. 10.1158/0008-5472.CAN-08-1078. MMP1, 2, 3 process the binding factors and free IGF, allowing it to bind to its receptors found both on osteoblasts and osteoclasts. Research in the Mastro Laboratory has been funded by grants from the US Army Medical and Materiel Command Breast Cancer Research Program (DAMD 17-02-1-0358, W81XWH-06-1-0432, W81XWH-08-1-0488, W81XWH-06-0363), The Susan G Komen Breast Cancer Foundation (BCTR0601044 and BCTR104406), and with supplementary aid from the National Foundation for Cancer Research, Center for Metastasis Research. It improves the quality of life by preventing fractures but does not prolong life [73]. 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. Osteo-blasts also produce osteoprotegerin (OPG), a decoy receptor to RANKL that curtails osteoclast activation. 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. Due to this, the bones get harder and cause the condition called sclerosis. These molecules cause osteoblasts not only to form new bone but also to release RANKL and other osteoclastic mediators. The authors declare that they have no competing interests. The site is secure. 2001, 142: 5050-5055. Clinically, complications secondary to bone metastasis include pain, pathologic fractures, spinal cord compression, and hypercalcemia of malignancy. Epub 2018 Jan 5. Gan To Kagaku Ryoho. The cancer cells affect osteoblast morphology and extracellular matrix. The mean standardized uptake value (SUV) for tumor was 7.1 versus 2.1 for benign lesions. Of the many prostaglandins, PGE2 is known to play a critical role in cancer progression. 10.1210/endo-86-6-1436. 2010. 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. 8600 Rockville Pike Pozzi S, Vallet S, Mukherjee S, Cirstea D, Vaghela N, Santo L, Rosen E, Ikeda H, Okawa Y, Kiziltepe T, Schoonmaker J, Xie W, Hideshima T, Weller E, Bouxsein ML, Munshi NC, Anderson KC, Raje N: High-dose zoledronic acid impacts bone remodeling with effects on osteoblastic lineage and bone mechanical properties. Abstract Metastasis of breast cancer cells to bone consists of multiple sequential steps. While EMMPRIN is produced normally during tissue remodeling, it increases during tumor progression and metastasis. Bethesda, MD 20894, Web Policies 2007, 57: 43-66. 2008, 34 (Suppl 1): S25-30. 10.1177/154405910608500703. PubMed Accessibility 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. This review summarizes the current understanding of the osteolytic mechanisms of bone metastases, including a discussion of current therapies. 7. 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. It is required to drive mesenchymal cells to become osteoblasts. 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. TGF- is one of the most prominent. Kozlow W, Guise TA: Breast cancer metastasis to bone: mechanisms of osteolysis and implications for therapy. Bone metastases may cause pain, may make the bones more susceptible to fractures, and may cause increased levels of calcium in the blood. Both RANKL and VEGF can induce osteoclast formation [48], and MMPs play a role in bone matrix degradation. Biochem Biophys Res Commun. At the tissue level, PDGF is involved in bone formation, wound healing, erythropoiesis and angiogenesis as well as tumor growth and lesion development [57]. Tian E, Zhan F, Walker R, Rasmussen E, Ma Y, Barlogie B, Shaughnessy JD: The role of the Wnt-signaling antagonist DKK1 in the development of osteolytic lesions in multiple myeloma. The blastic bone lesions are caused when the cancer cells release the fluids. Osteoblasts themselves are negatively affected by cancer cells as evidenced by an increase in apoptosis and a decrease in proteins required for new bone formation. Estrogen also increases osteoblast pro-collagen synthesis and decreases osteoblast apoptosis [63]. Current therapeutic targets are indicated in green. N Engl J Med. Other cells of the osteoblastic lineage include bone lining cells and osteocytes. A thorough review of bone remodeling is beyond the scope of this article, and there are several excellent, recent reviews [8, 9]. This increase in COX-2 results in increased secretion of PGE2, which binds to EP4 receptors on the surface of the osteoblasts. We also discuss known risk factors as well as detection and assessment of bone metastases. With rare exceptions, cancer that has spread to the bones can't be cured. 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. Standal T, Borset M, Sundan A: Role of osteopontin in adhesion, migration, cell survival and bone remodeling. 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]. IGF binding proteins keep this molecule latent. eCollection 2022. 2010, [Epub ahead of print]. 10.1056/NEJMoa030847. Cancer Res. The ratio of RANKL to OPG determines the extent of the osteoclast activity and bone degradation. In the bone, OPN is involved in the differentiation and activity of osteoclasts, and inhibition of mineral deposition in the osteoid [37]. These functional molecules complete the cycle and osteolysis continues. Thus, in the course of the osteolytic process, the osteoblasts are unable to fulfill their role as bone building cells. Actions of bisphosphonate on bone metastasis in animal models of breast carcinoma. In reality the system is much more complex (Table 1).

Breast cancer had the highest . Bone metastases are areas of cancer that develop when breast cancer cells travel to the bones. In this process, the older bone doesn't break down while the new bone forms. Studies with MMP9-null mice indicate its importance in tumor progression in ovarian cancer, prostate cancer and bone metastasis [56]. eCollection 2022. Radiol Clin North Am. Jemal A, Siegel R, Ward E, Murray T, Xu J, Thun MJ: Cancer Statistics, 2007. Current treatments can improve bone density, decrease skeletal related events and ease bone pain, yet existing bone lesions do not heal. Cancer Res. In the final stages of metastatic osteolytic breast cancer disease, the cancer cells, fueled by growth factors released from the degraded matrix, expand unchecked. This release of fluids and substances soon turns on the osteoblasts, which leads to the formation of new bone. Another growth factor sequestered in the matrix is IGF. Because of its significant role, TGF- has been a tempting therapeutic target. 2012 Aug;39(8):1174-7. Along with colleagues and students she has focused particularly on the fate of osteoblasts in the metastatic bone environment. 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. 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. However, cathepsin K is also produced by other cells in the bone microenvironment, such as macrophages and bone marrow stromal cells. volume12, Articlenumber:215 (2010) Stopeck A: Denosumab findings in metastatic breast cancer.

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]. In normal bone remodeling, osteoclasts secrete PDGF, which acts as a chemoattractant to recruit pre-osteoblasts to the site of bone repair [58]. In people with breast and prostate cancer, the bone is often the first distant site of cancer spread. An official website of the United States government. 10.1177/154405910608500704. The .gov means its official. The MMPs are considered to be important in the bone metastatic process. 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. Osteomimetic factors driven by abnormal Runx2 activation in breast cancer cells may increase their survival in the bone microenvironment. Bone lining cells appear microscopically as relatively undifferentiated cells that line the 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. Once osteoblasts finish bone deposition, they undergo apoptosis, remain in the matrix as osteocytes or revert to thin bone-lining cells. Endocr Rev. 10.1158/0008-5472.CAN-07-1046. MeSH 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. quiz S30, CAS Federal government websites often end in .gov or .mil. Clipboard, Search History, and several other advanced features are temporarily unavailable. 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. CA Cancer J Clin. Since the discovery of RANKL and its role in bone remodeling, the field of bone metastasis has moved rapidly. Clin Breast Cancer. Where do the MMPs come from?

Am J Pathol. According to this paradigm, the tumor cells produce a variety of growth factors, most notably parathyroid hormone-related protein (PTHrP) [18]. Breast Cancer Res. 2003, 349: 2483-2494. Even in adults it is estimated that about 10% of the bone is renewed each year [7]. Drugs of the bisphosphonate family have been used for many years as the standard of care. 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]. 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 normal processes of bone resorption and formation are remarkably well balanced. Mundy GR, Sterling JL: Metastatic solid tumors to bone. In males, prostate and lung cancers make up 80% of carcinomas metastasising to bone. Orr and colleagues [5] have determined MMPs sufficient to resorb bone in vitro and to contribute to the process in vivo. Estrogen has also been shown to promote osteoclast apoptosis and inhibit activation of mature osteoclasts. Clipboard, Search History, and several other advanced features are temporarily unavailable. 10.1111/j.0105-2896.2005.00326.x. Breast cancer frequently metastasizes to the skeleton. osteolytic bone metastases are characterized by destruction and loss of normal bone or bone matrix 1,2 in which parathyroid hormone-related peptide (pthrp) features a significant part in the evolution of osteolytic lesions by stimulating the differentiation and activating osteoclasts via the rankl pathway, which primarily mediate the degradation Recently we have begun developing an in vitro bioreactor [78].
