Mercer RR, Miyasaka C, Mastro AM: Metastatic breast cancer cells suppress osteoblast adhesion and differentiation. 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. Mundy GR: Mechanisms of bone metastasis. Careers. -, Proc Natl Acad Sci U S A. However, both drugs are associated with low incidence of osteonecrosis of the jaw [75]. 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. Metastasis of breast cancer cells to bone consists of multiple sequential steps. 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. In this process, the older bone doesn't break down while the new bone forms. Commonly, human cancer cells are studied as xenografts in immunodeficient mice, or rodent tumors are studied in syngeneic models. 2008, 68: 7795-7802. 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. Mastro AM, Vogler EA: A three-dimensional osteogenic tissue model for the study of metastatic tumor cell interactions with bone. 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. 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. All in all, PTHrP is an important mediator between breast cancer cells and cells of the bone microenvironment and, as such, is a major contributor to the bone degradation process. HDAC inhibitors induce LIFR expression and promote a dormancy phenotype in breast cancer. Osteoclasts derive from mononuclear myeloid precursors that fuse to form pre-osteoclasts. Bisphosphonates binding to hydroxyapatite are ingested by osteoclasts and cause their apoptosis. Of the many prostaglandins, PGE2 is known to play a critical role in cancer progression. 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]. It's not the same as having cancer that starts in the bone. All three doctors say that new, progressive pain in your bones or joints is the most common symptom of metastatic breast cancer in bones. Once bony metastases occur, cancer cure becomes impossible and in these cases radiation therapy, associated or not with systemic chemotherapy, may be . Mesoporous nanoplatform integrating photothermal effect and enhanced drug delivery to treat breast cancer bone metastasis. Further, we describe future directions for bone metastasis management, focusing on novel bone-specific targeted therapies. 1973, 28: 316-321. Doctors use imaging tests, such as x-rays, to figure out the types of . 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. Clin Cancer Res. In middle aged and elderly women, calcium and/or vitamin D deficiencies are quite common, as is the incidence of breast cancer [65]. Breast cancer metastasis to the bone: mechanisms of bone loss, http://breast-cancer-research.com/series/metastasis_pathway. Osteoblasts and bone stromal cells can respond to a variety of substances that upregulate RANKL. 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. 2010, 33 (3 Suppl): S1-7. Bethesda, MD 20894, Web Policies Epub 2015 Dec 4. VEGF also forms a complex with the extracellular matrix [31, 55]. 2010, 70: 1835-1844. 2007, 24: 599-608. This loss is more precipitous in women, due to the decrease in estrogen at menopause [3]. Am J Pathol. Since the discovery of RANKL and its role in bone remodeling, the field of bone metastasis has moved rapidly. Osteoblastic or blastic metastases cause an area of the bone to look denser or sclerotic. Endocrinology. CAS Studies with MMP9-null mice indicate its importance in tumor progression in ovarian cancer, prostate cancer and bone metastasis [56]. Federal government websites often end in .gov or .mil. 1974, 230: 473-475. 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]. In summary, all of these factors contribute to propagating the vicious cycle and increasing osteolysis (Figure 1B). Cancers (Basel). According to this paradigm, the tumor cells produce a variety of growth factors, most notably parathyroid hormone-related protein (PTHrP) [18]. 10.1210/endo-86-6-1436. The MMP family, composed of more than 20 members, can collectively degrade all components of the extracelluar matrix. Halpern J, Lynch CC, Fleming J, Hamming D, Martin MD, Schwartz HS, Matrisian LM, Holt GE: The application of a murine bone bioreactor as a model of tumor: bone interaction. Thus, bone loss is due to both increased activation of osteoclasts and suppression of osteoblasts. Cells of the monocyte-macrophage lineage are stimulated to form osteoclast progenitor cells. 2010, [Epub ahead of print]. 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]. Clin Oral Investig. PubMed Central Current therapies consist of blocking osteoclast activity as a means of disrupting the vicious cycle. Denosumab is an antibody directed to RANKL that prevents osteoclast differentiation. 2004, 26: 179-184. J Clin Oncol. The lesions can often be blastic but may also appear purely lytic, with poor margination, no matrix and cortical destruction. Proteolytic cleavage of SPARC releases biologically active cleavage products that affect angiogenesis factors such as VEGF, platelet-derived growth factor (PDGF) and FGF-2. PubMed Aldridge SE, Lennard TW, Williams JR, Birch MA: Vascular endothelial growth factor acts as an osteolytic factor in breast cancer metastases to bone. 10.1359/jbmr.060610. 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. 2008, 473: 98-105. Osteoclasts derive from hematopoietic stem cells. However, both bone degradation and deposition likely occur early in the metastatic process. In doing so, cancer cells are equipped to home, adhere, survive and proliferate in the bone microenvironment. Breast cancer-derived factors facilitate osteolytic bone metastasis. Guise [18] demonstrated that increasing the expression of PTHrP in cancer cells enhanced osteolytic lesions in vivo, while decreasing the expression reduced the number and size of lesions. Clinically, complications secondary to bone metastasis include pain, pathologic fractures, spinal cord compression, and hypercalcemia of malignancy. The results of an in vivo study showed that OPN-deficient mice showed significantly reduced bone metastasis [38]. Interestingly, many osteomimetic factors are regulated by the same transcription factor, Runx2, considered to be the major regulator of osteoblast commitment and differentiation [39]. 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. In addition, PDGF has been shown to inhibit osteoblast differentiation [60], making it an important factor in bone remodeling and the osteolytic bone metastasis. 2003, 300: 957-964. 10.1038/sj.bjc.6601437. 1988 Jun;7(2):143-88 Cancer Treat Rev. Verbruggen ASK, McCarthy EC, Dwyer RM, McNamara LM. Osteo-blasts also produce osteoprotegerin (OPG), a decoy receptor to RANKL that curtails osteoclast activation. Biochem Biophys Res Commun. IL-11, normally produced by bone marrow stromal cells and osteoblasts, is an important regulator of hematopoiesis and a potent promoter of osteoclast formation. Teriparatide, in contrast to bisphosphonates and denosumab, acts on osteoblasts to stimulate bone formation. 2022 Aug 6;10(8):1908. doi: 10.3390/biomedicines10081908. Increased production of EMMPRIN in turn leads to increases in VEGF and MMPs. 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. The cyclooxygenase enzymes COX-1 and COX-2 catalyze the conversion of arachidonic acid to prostaglandins and thromboxanes. 10.1158/0008-5472.CAN-07-1046. 2010, 70: 6150-6160. Biochem Biophys Res Commun. Blood. 2006, 12: 1431-1440. This information is not easily obtained with in vitro studies. Google Scholar, Mundy GR: Bone Remodeling and its Disorders. Google Scholar. 2000 Mar;18(6):1378-91. doi: 10.1200/JCO.2000.18.6.1378. PGs produced from this arachidonic acid conversion are both autocrine and paracrine factors that help to govern physiologic homeostasis. In addition, production of inflammatory cytokines (that is, IL-6, TNF-, M-CSF, IL-1) is suppressed by estrogen [64]. Metastatic breast cancer (also called stage IV or advanced breast cancer) is not a specific type of breast cancer. For example, a hydroxyapatite scaold pre-loaded with bone morphogenetic protein-2 enhanced the growth rate of mammary tumor cells in the scaold [77]. PubMed Along with colleagues and students she has focused particularly on the fate of osteoblasts in the metastatic bone environment. Other drugs on the horizon target TGF-, and cathepsin K. Various approaches, including kinase inhibitors, ligand-neutralizing antibodies and anti-sense molecules, are being investigated [33]. Article There are many suspected factors, such as microfractures, loss of mechanical loading, hormones, cytokines, calcium levels and inflammation. 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. 2010, 87: 401-406. Bone remodeling is often described as a cycle beginning with bone degradation and ending with bone deposition (Figure 1A). 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. At higher doses they may in fact prevent osteoblast differentiation [30]. Fragments of human fetal bone implanted in SCID mice allow one to examine human cancer with human bone [76]. Ganapathy and colleagues [24] found that TGF- antagonists are able to reduce bone metastasis and the number and activity of differentiated osteoclasts [24]. 2006, 21: 1350-1358. PubMed 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 . 2016 Apr 1;99(Pt B):206-211. doi: 10.1016/j.addr.2015.11.017. blastic (bone formation), or mixed lesions (Fig 2). Estrogen also increases osteoblast pro-collagen synthesis and decreases osteoblast apoptosis [63]. Google Scholar. Lung cancer is the third most common site of origin of metastatic cancer deposits in bone, after breast and prostate cancer. 10.2353/ajpath.2009.080906. Clin Orthop Relat Res. 2009, 11: R56-10.1186/bcr2345. For females, breast and lung are the most common primary sites ; nearly 80% of cancers that spread to the skeleton are from these locations. Feng X, McDonald JM: Disorders of bone remodeling. C-SRC tyrosine kinase activity is associated with tumor colonization in bone and lung in an animal model of human breast cancer metastasis. 10.1056/NEJMe1010459. Cathepsin K is believed to be the major protease in this capacity. 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. Marie PJ: Transcription factors controlling osteoblastogenesis. It is estimated that osteolytic lesions occur in 60 to 95% of myeloma patients [1, 27]. Myeloma cells produce factors that upregulate osteoblast production of M-CSF and RANKL and downregulate production of OPG. This review summarizes the current understanding of the osteolytic mechanisms of bone metastases, including a discussion of current therapies. This area has been likened to an extracellular lysosome [11]. 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]. RANKL clearly holds the key to the osteolytic process. Kingsley LA, Fournier PG, Chirgwin JM, Guise TA: Molecular biology of bone metastasis.

Lipton A: Emerging role of bisphosphonates in the clinic--antitumor activity and prevention of metastasis to bone. 2010. Parathyroid hormone-related protein and bone metastases. 2 Of interest is that patients with blastic (versus osteolytic) bone metastases have been reported to have prolonged survival. Breast cancer had the highest . This approach will allow testing of components and drugs in a model less complex than an animal but more relevant than standard tissue culture. While EMMPRIN is produced normally during tissue remodeling, it increases during tumor progression and metastasis. J Dent Res. Lerner UH: Bone remodeling in post-menopausal osteoporosis. PubMed The blastic bone lesions are caused when the cancer cells release the fluids. 2005, 208: 194-206. However, this approach has not entirely solved the problem. A thorough review of bone remodeling is beyond the scope of this article, and there are several excellent, recent reviews [8, 9]. PTHrP, one of many proteins controlled by Runx2, is a major effector in breast cancer bone metastasis progression and bone loss. 2005, 310: 270-281. eCollection 2022.
