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]. Lung cancer is the third most common site of origin of metastatic cancer deposits in bone, after breast and prostate cancer. Biochem Biophys Res Commun. 2008, Washington, DC: American Society for Bone and Mineral Research, 374-378. full_text. This increase in COX-2 results in increased secretion of PGE2, which binds to EP4 receptors on the surface of the osteoblasts. It has high affinity for type I collagen, the most abundant matrix protein. In males, prostate and lung cancers make up 80% of carcinomas metastasising to bone. These capacities are essential for any cancer cells to develop distant metastases in organs such as lungs and liver as well as bone. PubMed The resorption phase of the process begins with recruitment of pre-osteoclasts that differentiate into activated osteoclasts under the direction of osteoblasts (Figure 1A). 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. 10.3816/CBC.2005.s.004. The dynamics of this system are interrupted when metastatic breast cancer cells are introduced, adding another layer of active molecules to the bone environment. In many cases, osteolytic and osteoblastic changes occur simulta-neously.28 Up to half of all bone metastases from breast cancer tend to show osteolytic changes.5,7,29-31 However, because all types of bone metastases show . Bisphosphonates binding to hydroxyapatite are ingested by osteoclasts and cause their apoptosis. 2010, 126: 1749-1760. 2007, 24: 599-608. Development of clinically relevant in vivo metastasis models using human bone discs and breast cancer patient-derived xenografts. At the tissue level, PDGF is involved in bone formation, wound healing, erythropoiesis and angiogenesis as well as tumor growth and lesion development [57]. Mundy GR: Mechanisms of bone metastasis. Teriparatide, in contrast to bisphosphonates and denosumab, acts on osteoblasts to stimulate bone formation. Clinically, complications secondary to bone metastasis include pain, pathologic fractures, spinal cord compression, and hypercalcemia of malignancy.

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. Another drug, teriparatide (Forteo), the amino-terminal 34 amino acids of parathyroid hormone, has been used for many years to treat osteoporosis. 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. 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]. They also are regulators of other molecules important in the vicious cycle. The lesions can often be blastic but may also appear purely lytic, with poor margination, no matrix and cortical destruction. Osteoclasts derive from hematopoietic stem cells. COX-2 activity in breast cancer cells has also been found to modulate the expression and activity of MMPs. PubMed Central Disclaimer, National Library of Medicine Would you like email updates of new search results? 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). Thus, the ratio of RANKL to OPG is critical for osteoclast activation. . It is now generally accepted that the bone microenvironment is critical to the colonization and growth or dormancy of metastases. 2022 Nov 30;10:1088823. doi: 10.3389/fchem.2022.1088823. 10.1016/j.yexcr.2005.07.029. 10.1016/S0531-5565(03)00069-X. In the section that follows, we will discuss in greater detail the key factors involved in metastatic breast cancer osteolysis. There is evidence that bisphosphonates also contribute to tumor cell death, especially in combination with chemotherapy [72].

Clarke BL, Khosla S: Physiology of bone loss. 2007, 57: 43-66. Until recently they were the only FDA approved drugs for metastatic bone disease [71]. 1997, 80 (8 Suppl): 1572-1580. 2000, 1: 331-341. 2005, 10: 169-180. The role of lining cells. AMM, the senior investigator and corresponding author, has worked in the area of breast cancer metastasis to bone for over 12 years. 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. In the bone, OPN is involved in the differentiation and activity of osteoclasts, and inhibition of mineral deposition in the osteoid [37]. 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 ]. 10.1158/0008-5472.CAN-08-1078. Osteoblast differentiation is suppressed; new osteoid production is no longer able to keep pace with bone resorption. Mouse Models of Tumor Bone Metastasis and Invasion for Studying CCN Proteins. While EMMPRIN is produced normally during tissue remodeling, it increases during tumor progression and metastasis. The cancer cells affect osteoblast morphology and extracellular matrix. Blood. 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. Exp Oncol. (A) The bone remodeling unit consists of osteoblasts, which produce osteoid, bone matrix, and osteoclasts, which degrade mineralized bone. A smoking history is almost always present.

The cyclooxygenase enzymes COX-1 and COX-2 catalyze the conversion of arachidonic acid to prostaglandins and thromboxanes. What Are The Symptoms Of Bone Metastasis In Breast Cancer. Further stimulation results in large multinuclear cells capable of bone resorption. The .gov means its official. In the 1960s and 70s it was proposed that bone degradation might result from the physical pressure of the tumor on the bone and/or direct resorption of the bone by tumor cells. Breast Cancer Res. Kubota K, Sakikawa C, Katsumata M, Nakamura T, Wakabayashi K: PDGF BB purified from osteoclasts acts as osteoblastogenesis inhibitory factor (OBIF). Cells of the osteoblast lineage are derived from mesenchymal stem cells, and are represented in this unit by osteoblasts, bone lining cells and osteocytes. 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]. 2010, 115: 140-149. J Bone Oncol. Khosla S: Minireview: the OPG/RANKL/RANK system. Article PubMed Central Ann N Y Acad Sci. 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. The osteoclasts work as part of the bone remodeling compartment, underneath a canopy of bone lining cells. However, the MMPs may be involved in matrix remodeling once the osteoclasts are finished. HHS Vulnerability Disclosure, Help Am J Pathol. 10.1056/NEJMoa030847. What can be done to stop osteolytic metastasis? 2006, 6: 181-10.1186/1471-2407-6-181. CAS 2010, 33 (3 Suppl): S1-7.

The other 20% of primary disease sites in both sexes are: kidney, thyroid, gastrointestinal tract and other locations. Osteocytes are terminally differentiated osteoblasts that become embedded in the bone matrix at the end of the deposition phase of remodeling. 2010. 10.1210/endo-86-6-1436. 2010, 2: 907-915. eCollection 2022. Lynch CC: Matrix metalloproteinases as master regulators of the vicious cycle of bone metastasis. 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. In addition, pre-clinical trials with agents that target cathepsin K, certain matrix metalloproteinases (MMPs), and transforming growth factor (TGF)- are underway. One of its substrates is SPARC (secreted protein acidic and rich in cysteine; osteonectin/BM-40) [51]. Springer Nature. Cancer.

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. More than 2 out of 3 breast and prostate cancers that . Metastatic breast cancer cells tend to spread to the bones more often than they do to other parts of the body. & Mastro, A.M. Nevertheless, the inaccessibility, opacity and size of the skeleton make it difficult to study even in laboratory animals. In a recent comprehensive review article, Lynch [50] presents the case that they are 'master regulators' of the vicious cycle. 10.1016/S0959-8049(00)00363-4. 10.1097/00003086-200004000-00013. For females, breast and lung are the most common primary sites ; nearly 80% of cancers that spread to the skeleton are from these locations. Thus, Runx2 plays a significant role in the vicious cycle via TGF--induced IHH-PTHrP pathways in breast cancer cells, resulting in increased osteoclastogenesis and osteolysis. C-SRC tyrosine kinase activity is associated with tumor colonization in bone and lung in an animal model of human breast cancer metastasis. 1991 Apr 1;47(6):922-8 J Bone Miner Res. This feature accounts for the variable sensitivity and specificity of different imaging modalities. 10.1002/(SICI)1097-0142(19971015)80:8+<1546::AID-CNCR4>3.0.CO;2-I. This is a disease of clonal malignancy of terminally differentiated plasma cells that accumulate in the bone marrow. Current therapies consist of blocking osteoclast activity as a means of disrupting the vicious cycle. Front Biosci (Schol Ed). Clin Orthop Relat Res. Thus, inflammation is likely to be important in cancer initiation, metastasis and the resulting osteolysis.
