From the large reduction in tumor burden brought about by doxycycline, it appears more likely that the effectiveness relies on the properties of doxycycline as an inhibitor of tumor cell proliferation and less on its effect as a MMP inhibitor, because only a relative modest decrease in bone resorption was observed. Other osteolytic bone metastasis models, such as the one using orthotopic injections of 4T1 mouse mammary tumor cells (20) , will be examined in future studies to confirm our data obtained with the MDA-MB-231 cells. Our results suggest that doxycycline may be useful not only for the treatment of osteolytic but also for the treatment of osteoblastic bone metastasis. However, this remains to be determined using animal models specific for osteoblastic bone metastasis, such as the MCF-7 human breast cancer cell model (20) . The mechanism of action of doxycycline is very different from that of the bisphosphonate family of drugs that are used as therapeutic agents in clinical disorders ...

Q: My friend is only 16 but he was just diagnosed with cancer in his leg bone. Is this common?A: There are many cancers that can metastasize to the bones (so these are not primary bone cancers), but there are also some primary bone cancers that arise directly from cancerous bone cells. Osteosarcoma (OS) is the most common primary bone cancer, although overall it is a rare cancer representing only about 1 percent of all cancers diagnosed in the U.S. There are few than 1,000 new cases of OS

Recent studies have contributed to the enhancement of clinical and molecular knowledge on bone lymphomas, a group of rare malignancies with particular characteristics. Nevertheless, several questions remain unanswered and the level of evidence supporting some diagnostic and therapeutic decisions remains low. Currently, three different forms of bone lymphomas can be distinguished: the primary bone lymphoma, consisting of a single bone lesion with or without regional lymphadenopathies; the polyostotic lymphoma, consisting of multifocal disease exclusively involving the skeleton; and the disseminated lymphoma with secondary infiltration of the skeleton. The first two forms exhibit a good prognosis, requiring treatments similar to those commonly used for nodal lymphomas of the same category, but several issues regarding the role of surgery and local control of the disease, the sequence of treatment, radiation volumes and doses, management of pathological fractures and prevention of late sequelae deserve

Primary bone lymphoma (PBL) is a rare but distinct clinicopathological disease. Because it is not common, the optimal treatment strategy has not been established. Here, we present a patient with PBL of the left radius and review the related literature. We focus on the standard treatment for PBL. Many aspects such as rehabilitation, local control and overall survival need to be considered. Studies on this disease should be carried out to clarify the optimal treatment in the future.

Tumor-induced bone disease is common among patients with advanced solid cancers, especially those with breast, prostate, and lung malignancies. The tendency of these cancers to metastasize to bone and induce bone destruction is, in part, due to alterations in integrin expression and signaling. Substantial evidence from preclinical studies shows that increased expression of integrin αvβ3 in tumor cells promotes the metastatic and bone-invasive phenotype. Integrin αvβ3 mediates cell adhesion to several extracellular matrix proteins in the bone microenvironment which is necessary for tumor cell colonization as well as the transmission of mechanical signals for tumor progression. This review will discuss the αvβ3 integrin receptor in the context of tumor-induced bone disease. Specifically, the focus will be the role of αvβ3 in modulating cancer metastasis to bone and tumor cell response to the bone microenvironment, including downstream signaling pathways that contribute to tumor-induced osteolysis.

The skeleton is a frequent and clinically relevant site of metastasis in cancer patients. The major events related to bone metastases include bone pain, bone loss, hypercalcemia, spinal cord compression, and fractures. On the basis of their radiographic features, bone metastases are classified as osteoblastic, osteoclastic, or mixed. The primary goals of treatment of bone metastases are reduction of the risk of pathological fractures and other skeletal-related events, and pain control. Bisphosphonates are used to prevent pathological fractures by ...

Bone metastasis is a complex process that needs to be better understood in order to help clinicians prevent and treat it. Xenografts using patient-derived material (PDX) rather than cancer cell lines are a novel approach that guarantees more clinically realistic results. A primary culture of bone metastasis derived from a 67-year-old patient with breast cancer was cultured and then injected into zebrafish (ZF) embryos to study its metastatic potential. In vivo behavior and results of gene expression analyses of the primary culture were compared with those of cancer cell lines with different metastatic potential (MCF7 and MDA-MB-231). The MCF7 cell line, which has the same hormonal receptor status as the bone metastasis primary culture, did not survive in the in vivo model. Conversely, MDA-MB-231 disseminated and colonized different parts of the ZF, including caudal hematopoietic tissues (CHT), revealing a migratory phenotype. Primary culture cells disseminated and in later stages extravasated from the

Project summary Breast cancer frequently metastasizes to be where it leads to osteolysis and poor clinical prognosis; however, the role of hydroxyapatite nanocrystals (HA, the mineral component of bone) in this process remains unclear due, in part, to the lack of appropriate culture models. The overall goal of these studies is to design a mineralized 3-D tumor model that captures the intrinsic 3-D cell-microenvironment interactions within bone- metastatic niches and nanostructural alterations of HA that may occur due to disease and aging. Specifically, we will develop porous poly (lactide-co-glycolide) (PLG) scaffolds that incorporate HA nanoparticles of defined physicochemical characteristics and assess the applicability and relevance of this 3-D tumor model to test the functional relationships between HA and osteolytic bone metastasis. This work will be accomplished in three specific aims: In Aim 1, we will develop the 3-D matrices by synthesizing monodispersed nanoparticles of HA with ...

The bone marrow provides a specialized and highly supportive microenvironment for tumor growth and development of the associated bone disease. It is a preferred site for breast and prostate cancer bone metastasis and the hematologic malignancy, multiple myeloma. For many years, researchers have focused upon the interactions between tumor cells and the cells directly responsible for bone remodeling, namely osteoclasts and osteoblasts. However, there is ever-increasing evidence for a multitude of ways in which the bone marrow microenvironment can promote disease pathogenesis, including via cancer-associated fibroblasts, the hematopoietic stem cell niche, myeloid-derived suppressor cells, and the sympathetic nervous system. This review discusses the recent advances in our understanding of the contribution of the host microenvironment to the development of cancer-induced bone disease.

Primary bone cancer starts in bone or cartilage while metastatic bone cancers begin elsewhere in the body and spread to bones. Learn about how they differ.

Bone metastases are frequently one of the first signs of disseminated disease in cancer patients. Skeletal complications due to metastatic disease include (severe) bone pain, impaired mobility, spinal cord compression, pathological fractures, and hypercalcemia. Radiotherapy and surgery are the options for the specific local treatment of bone metastases. Chemotherapy, hormonotherapy and bisphosphonates are systemic weapons used in the treatment of bone metastases with or without hypercalcemia. Cancers with propensity to metastasize to bones such as breast, prostate, lung and myeloma may possess the capacity to interact with osteoclasts. Osteoclasts are specialized bone cells, which erode mineralized bone by secreting acids and lysosomal enzymes. In normal bone remodeling, osteoclastic bone resorption is coupled to and is in equilibrium with osteoblastic bone formation. The lytic bone destruction associated with malignant bone metastases develops because tumor cells synthesize and release soluble ...

Recurring breast cancer can sometimes spread to your bones. A long-term study conducted by the by the Hacettepe University Institute of Oncology in Turkey on 141 women with breast cancer and bone metastasis found that the median survival rate was two years, according to ascopubs.org.

EN] Bone metastases are a common complication in some high incidence types of cancer, like prostate or breast cancer. The complications associated with bone metastases include bone pain, fractures and spinal cord compression. Most part of bone metastases are irreversible and treatments are focused on slowing the growth of the lesions. In the United States, 17% of the total direct medical cost was employed treating bone metastases. In order to improve the health of the patients and cut down medical costs, early detection is crucial. Some studies have shown that Whole-Body MRI has the potential to become the best method for diagnosis but there are still some difficulties left. One patient can have multiple bone metastases all over the skeleton in different sizes. This makes diagnosing bone metastases a tough task for the radiologists and because of the irregular shapes of the bone metastases, changes in size are also difficult to measure. The goal of this project is to provide an automatic tool ...

Ablative treatment of metastatic bone tumors and relief of pain associated with metastatic bone tumors is achieved by heat ablation of the bone tumor or tissue near the bone tumor by an ablation probe. In one form the probe is an electrode coupled to a high frequency power supply to provide ablative heating of tissue proximate to an electrode that is placed in or near the bone tumor. Cooling of the electrode by fluid circulation from a cooling apparatus outside the patients body may be used to enlarge the region of high frequency heating around the electrode. Image guidance of the electrode placement may be monitored by an imaging device. Tracking of the electrode by an image-guided navigator helps in placement of the electrode with respect to the configuration of the bone and bone metastasis. A set of tools accommodates biopsy and various shapes of electrodes according to clinical requirements. Several forms of electrodes, energy delivery and cooling apparatus and methods accommodate the specific

Results of the trial were presented today (Sunday) at the 2011 European Multidisciplinary Cancer Congress [1].. Professor Peter Hoskin, consultant clinical oncologist at the Mount Vernon Cancer Centre, Northwood, UK, and Professor of Clinical Oncology at University College, London, and colleagues, randomised 470 patients with primary prostate cancer and painful bone metastases to receive either a single dose of radiation or a single intravenous infusion of the bisphosphonate ibandronate (IB). Patients reported their primary site of pain at entry into the trial, and then at four, eight, twelve, 26 and 52 weeks after treatment.. Those who had not responded to the first treatment at four weeks crossed over to the alternative therapy and received their second treatment no later than week eight. Pain levels were measured at four and twelve weeks by examining analgesic use, using a combination of scoring via the WHO pain ladder [2] and the Mercadante method, which defines analgesic use in morphine ...

This proposal studied the role of TGF Beta signaling in prostate cancer. To summarize, it is a useful target for treatment of prostate cancer bone metastases, provided that the tumor cells are responsive to the factor and show components of osteolytic lesions. TGF Beta inhibitors are not beneficial when the bone metastases phenotype is predominantly osteoblastic. Smad-independent pathways downstream of the TGF Beta receptors, such as p38 MAP kinase, do not appear to be appropriate targets for pharmacological treatment of prostate cancer bone metastases. There is no advantage to combined treatment targeting TGF Beta receptors and p38 MAP kinase. PMEPA1 may be an important target of TGF Beta in prostate cancer cells and responsible for potentiating responsiveness of tumor cells in bone to the local actions of bone-released TGF Beta. Its regulation and isoformspecific effects are complex and will be the subject of future grant proposals. TGF Beta inhibition increases bone mass systemically thru effects to

N2 - Formation of bone metastasis is a hallmark of the progression of several solid cancers, providing example for the organ specificity of the process. Bone metastasis may result in both venous and arterial dissemination. Though the molecular basis of the lytic and plastic bone metastasis formation is different, in reality these organ metastases represent a mixture of the two processes. The basis of bone metastasis formation is the activation of osteoclasts and the resulting bone resorption, initiating a vicious circle by activating the initiator cancer cell. The discovery of osteoclast-bone matrix interaction inhibitor bisphosphonates revolutionized the therapy of bone metastasis. Clarifying the molecular pathways involved in bone metastasis formation identified osteoclast differentiation as another feasible target. This process is under control of the TNF ...

While prostate cancer metastatic lesions are the result of dysregulated activities of osteoclasts and osteoblasts, osteoblasts remain the key drivers in prostate cancer progression. Radiological evidence indeed shows osteoblastic lesions found located near osteoblast areas (6) and thus rationalizes an osteoclast-free approach in the first instance, as also highlighted by others (13).. Various models of bone metastasis/metastases have emerged in the past few decades, targeting different aspects of bone metastasis. They include 2D Transwell cocultures, multicellular spheroids (scaffold-free) (26), cell-encapsulated bioprinted/engineered matrices (scaffold-based) (27, 28), and ex vivo cultures (29) and can be used in static or dynamic modes (13). While every model comes with its pros and cons, only a few models have been used to answer relevant biological questions, such as assessing the effects of current or new drugs in the bone tumor microenvironment. An exception is the work by Fong et al. ...

Introduction: Bone metastases are the most common cause of cancer-related pain in various primary malignant tumors, most often, breast and prostate. 188Re-hydroxyethylidene diphosphonate (188Re-HEDP) is a new and less expensive bone seeking radiopharmaceutical with favorable physical characteristics of the radionuclide such as short half life of 16.9h, maximal β energy of 2.1 MeV with a 15% γ-component of 155 keV and easily available from an in-house 188W/188Re generator. The aim of this study is to evaluate the therapeutic efficacy and safety profile of bone palliative therapy following administration of 188Re-HEDP. Methods: Twenty patients with painful metastatic bone lesions secondary to breast, prostate, multiple myeloma, ampulla of vater and lung cancers received 1 mCi/kg of 188Re-HEDP. Four hours after treatment, post-therapy scintigraphy was performed. All patients were interviewed using a standard set of questions (visual analogue scale: VAS) concerning their pain relief before, and after

Primary malignant bone tumours, osteosarcomas, and Ewing sarcomas are rare diseases which occur mainly in adolescents and young adults. With the current therapies, some patients remain very difficult to treat, such as tumour with poor histological response to preoperative CT (or large initial tumour volume for Ewing sarcomas not operated), patients with multiple metastases at or those who relapsed. In order to develop new therapies against these rare tumours, we need to unveil the key driving factors and molecular abnormalities behind the malignant characteristics and to broaden our understanding of the phenomena sustaining the metastatic phenotype and treatment resistance in these tumours. In this paper, starting with the biology of these tumours, we will discuss potential therapeutic targets aimed at increasing local tumour control, limiting metastatic spread, and finally improving patient survival.

The microenvironment at the site of tumor metastasis plays a key role in determining the fate of the metastasizing tumor cells. This ultimately has a direct impact on the progression of cancer. Bone is the preferred site of metastasis of breast cancer. Painful, debilitating osteolytic lesions are formed as a result of crosstalk between breast cancer cells and cells in the bone, predominantly the osteoblasts and osteoclasts. In this paper, we have discussed the temporal and spatial role of hedgehog (Hh) signaling in influencing the fate of metastatic breast cancer cells in bone. By virtue of its secreted ligands, the Hh pathway is capable of homotypic and heterotypic signaling and consequently altering the microenvironment in the bone. We also have put into perspective the therapeutic implications of using Hh inhibitors to prevent and/or treat bone metastases of breast cancer.

Bone metastasis, or the development of secondary tumors within the bone of cancer patients, is a debilitating and incurable disease. Despite its morbidity, the biology of bone metastasis represents one of the most complex and intriguing of all oncogenic processes. This complexity derives from the intricately organized bone microenvironment in which the various stages of hematopoiesis, osteogenesis, and osteolysis are jointly regulated but spatially restricted. Disseminated tumor cells (DTCs) from various common malignancies such as breast, prostate, lung, and kidney cancers or myeloma are uniquely primed to subvert these endogenous bone stromal elements to grow into pathological osteolytic or osteoblastic lesions ...

Osteosarcoma is a malignant bone tumor with a high potential for lung metastasis, and the prognosis for patients with metastatic disease is very poor. The interaction between fibronectin (FN) and integrin αvβ3 in soft-tissue sarcoma promotes cell migration, invasion, and lung metastasis. This study aimed to investigate the prognostic significance of FN and αvβ3 in osteosarcoma. Immunohistochemistry and western blotting were used to detect the expression of FN and αvβ3 in 60 osteosarcoma specimens and in 30 osteochondroma specimens. Furthermore, correlations of FN and αvβ3 with the clinicopathological features of osteosarcoma patients were analyzed using the χ2 test and Fishers exact test. Disease-free survival and overall survival of osteosarcoma patients were assessed using the Kaplan-Meier method and Cox proportional hazards model. The predictive accuracy of the model was determined by the Harrell concordance index. FN (P | 0.05) and αvβ3 (P | 0.05) were overexpressed in osteosarcoma

We will conduct a prospective trial to verify the validity of indices utilizing TGF-b1, NF-kB, PET/CT, and MRS for predicting response to neoadjuvant chemotherapy in osteosarcoma patients. We assume that changes in plasma TGF-b1 levels, PET/CT and magnetic resonance spectroscopy (MRS) findings during the period of neoadjuvant chemotherapy as well as the initial nuclear NF-kB expression status of tumor biopsy specimen either alone or in combination may predict a chemotherapeutic response determined by histopathologic necrosis fractions of tumors removed. To test this, we will obtain TGF-b1 levels, PET/CT and MRS findings at diagnosis and at follow-up (after first and second/third chemotherapy cycle). Tumor will then be removed. Chemotherapy regimen comprised of various combination of cisplatin, adriamycin, and high-dose methotrexate, ifosfamide, and etoposide. Indices derived from TGF-b1, PET/CT, MRS predicting greater than 90% necrosis fractions will be sought utilizing statistical methods ...

Osteosarcomas are the most common primary malignant bone tumor that occurs in children and adolescents, and they frequently occur around the knee. In the past, amputation or joint disarticulation was the standard of care. Currently, more than 90% of osteosarcoma resections are limb-sparing procedures because of advancements in chemotherapeutic regimens and three-dimensional imaging studies, including CT and MRI. In addition, joint-sparing surgery is possible in select patients. To preserve the joint structure for good limb function in patients with osteosarcoma, we have been performing epiphyseal or metaphyseal osteotomy and biologic reconstruction via frozen autograft treated with liquid nitrogen. Several advantages are expected with the use of the freezing technique. This strategy involves simple surgical technique without specialized devices. A perfect fit is achieved because the managed bone is the patients own and bone strength is maintained postoperatively. Satisfactory bone union and

Abstract: Many patients with cancer develop symptomatic skeletal metastases at an advanced stage of their disease. Skeletal metastases are often complicated by pain. They cause considerable morbidity and mortality. Besides analgesics, treatment options include external beam radiotherapy, bisphosphonates, chemotherapy, surgery and bone seeking radiopharmaceuticals. Pain palliation with bone seeking radiopharmaceuticals has proved to be an effective treatment modality in patients with metastatic bone pain. Radiopharmaceuticals bind to the bone ...

TY - JOUR. T1 - Secondary osteosarcoma. T2 - Is there a predilection for the chondroblastic subtype?. AU - Barker, Jordan P.. AU - Monument, Michael J.. AU - Jones, Kevin B.. AU - Putnam, Angelica R.. AU - Randall, R. PY - 2015/5/1. Y1 - 2015/5/1. N2 - Osteosarcoma is the most common form of primary bone cancer in the adolescent and young adult patient population. Outcomes in patients with secondary osteosarcoma are inferior compared with outcomes in patients with primary osteosarcoma. The goal of this study was to investigate whether there is a predilection for the chondroblastic histologic subtype in secondary osteosarcoma. A retrospective chart review was performed to identify cases of secondary osteosarcoma treated at 1 institution from 1991 to 2012. Histologic subtypes were evaluated by a pathologist, and a review of the literature was also performed to identify the histologic subclassification of additional series of secondary osteosarcomas. Of a total of 131 cases of osteosarcoma, 9 ...

Prostate cancer metastases primarily localize in the bone where they induce a unique osteoblastic response. Elevated Notch activity is associated with high-grade disease and metastasis. To address how Notch affects prostate cancer bone lesions, we manipulated Notch expression in mouse tibia xenografts and monitored tumor growth, lesion phenotype, and the bone microenvironment. Prostate cancer cell lines that induce mixed osteoblastic lesions in bone expressed 5-6 times more Notch3, than tumor cells that produce osteolytic lesions. Expression of active Notch3 (NICD3) in osteolytic tumors reduced osteolytic lesion area and enhanced osteoblastogenesis, while loss of Notch3 in osteoblastic tumors enhanced osteolytic lesion area and decreased osteoblastogensis. This was accompanied by a respective decrease and increase in the number of active osteoclasts and osteoblasts at the tumor-bone interface, without any effect on tumor proliferation. Conditioned medium from NICD3-expressing cells enhanced osteoblast

Osteosarcoma, a primary bone cancer. The osteosarcoma is one of the primary cancers of the bone, that is to say developed from bone cells, cartilage or fibrous tissue, as opposed to secondary cancers of the bone metastases that are of cancer in another organ. The osteosarcoma is primary bone cancer the most common, before the chondrosarcoma, Ewings sarcoma and multiple myeloma . Of unknown cause, osteosarcoma usually occurs in children and young adults, between 10 and 25 years. The bones are usually affected long bones near the knee or shoulder: tibia, femur and humerus. We traditionally distinguish two forms of osteosarcoma: one attacks the central part of the bone (medullary bone), the other in the peripheral zone of the bone, destroying the periosteum, the membrane that surrounds the bone and is responsible for its growth in thickness. You should also remember that osteosarcoma can spread through the bloodstream and invade the lungs causing pulmonary metastases.. The first signs of ...

Eight patients presented without any evidence of metastatic disease; 4 of them had advanced local disease, including large tumour mass with soft-tissue compromise, neurovascular encasement and pathological fracture. Limb salvage was performed in 2/8 patients who presented without metastatic disease, both of whom had a proximal tibial tumour, and underwent wide resection and megaprosthesis total knee replacement.. Three of the patients were older than expected for primary osteosarcoma, aged 40, 51 and 53 years, respectively. Two of these patients were HIV-1 infected; further research is being conducted to determine the causality, if any, between osteosarcoma and HIV-1 infection.. Discussion. Osteosarcoma is a primary malignant bone tumour that is characterised by the proliferation of malignant mesenchymal cells capable of the direct production of osteoid.3,4,6,9 The World Health Organizations histological classification further divides osteosarcoma into medullary and surface tumours, which are ...

ISSN 2309-8309. http://dx.doi.org/10.17159/2309-8309.. BACKGROUND: Primary bone tumours of the spine are a group of rare tumours that include both benign and malignant lesions. Resection is associated with a high morbidity rate. METHODS: We retrospectively reviewed all the primary bone tumours of the spine that were surgically treated at our unit between 2005 and 2012 (haematological malignancies were excluded. RESULTS: Fifteen cases were included that presented at a median age of 36 years (range 8 to 65 years). Pain was the most common presenting symptom. Three patients had significant neurological deficits at time of presentation and in two cases there was an improvement after surgery. The median delay in diagnosis was 7 months (range 1 to 36 months). A variety of surgical strategies was employed with the use of adjuvant radio- ...

To estimate the costs (paid amounts) of palliative radiation episodes of care (REOCs) to the bone for patients with bone metastases secondary to breast or prostate cancer. Claims-linked medical records from patients at 98 cancer treatment centers in 16 US states were analyzed. Inclusion criteria included a primary neoplasm of breast or prostate cancer with a secondary neoplasm of bone metastases; ≥2 visits to ≥1 radiation center during the study period (1 July 2008 through 31 December 2009) on or after the metastatic cancer diagnosis date; radiation therapy to ≥1 bone site; and ≥1 complete REOC as evidenced by a |30-day gap pre- and post-radiation therapy. The total number of REOCs was 220 for 207 breast cancer patients and 233 for 213 prostate cancer patients. In the main analysis (which excluded records with unpopulated costs) the median number of fractions per a REOC for treatment of metastases was 10.

N2 - Osteosarcoma is the most common bone cancer in children and adolescents. Although 70% of patients with localized disease are cured with chemotherapy and surgical resection, patients with metastatic osteosarcoma are typically refractory to treatment. Numerous lines of evidence suggest that cytotoxic T lymphocytes (CTLs) limit the development of metastatic osteosarcoma. We have investigated the role of PD-1, an inhibitory TNFR family protein expressed on CTLs, in limiting the efficacy of immune-mediated control of metastatic osteosarcoma. We show that human metastatic, but not primary, osteosarcoma tumors express a ...

The reciprocal interaction between cancer cells and the tissue-specific stroma is critical for primary and metastatic tumor growth progression. Prostate cancer cells colonize preferentially bone (osteotropism), where they alter the physiological balance between osteoblast-mediated bone formation and osteoclast-mediated bone resorption, and elicit prevalently an osteoblastic response (osteoinduction). The molecular cues provided by osteoblasts for the survival and growth of bone metastatic prostate cancer cells are largely unknown. We exploited the sufficient divergence between human and mouse RNA sequences together with redefinition of highly species-specific gene arrays by computer-aided and experimental exclusion of cross-hybridizing oligonucleotide probes. This strategy allowed the dissection of the stroma (mouse) from the cancer cell (human) transcriptome in bone metastasis xenograft models of human osteoinductive prostate cancer cells (VCaP and C4-2B). As a result, we generated the osteoblastic

Deregulation of microRNA (miRNA) transcript levels has been observed in many types of tumors including osteosarcoma. Molecular pathways regulated by differentially expressed miRNAs may contribute to the heterogeneous tumor behaviors observed in naturally occurring cancers. Thus, tumor-associated miRNA expression may provide informative biomarkers for disease outcome and metastatic potential in osteosarcoma patients. We showed previously that clusters of miRNAs at the 14q32 locus are downregulated in human osteosarcoma. Human and canine osteosarcoma patients samples with clinical follow-up data were used in this study. We used bioinformatics and comparative genomics approaches to identify miRNA based prognostic biomarkers in osteosarcoma. Kaplan-Meier survival curves and Whitney Mann U tests were conducted for validating the statistical significance. Here we show that an inverse correlation exists between aggressive tumor behavior (increased metastatic potential and accelerated time to death) and the

Ewings sarcoma: a primary bone cancer. Ewing sarcoma is one of the primary tumors of bone, that is to say that cancer cells originate from bone, and that are not met static cancer located elsewhere in another organ. Ewing sarcoma is unique in touch more often men than women. It also develops mainly in children between 10 and 15 years , more rarely in young adults up to age 25. Cancer cells usually reach the long bones like the femur and tibia. Thus Ewing sarcoma most often for the arms and legs, even though this cancer can affect any bone.. Bone cancer: what are the symptoms of Ewings sarcoma?. The symptoms are typically those of bone cancer: bone cancer is painful and swollen. Moreover, it is fragile and may break at the slightest shock. When the tumors grew, they can sometimes go up to affect the bone throughout its length. The diagnosis of Ewings sarcoma is based on the radiograph but also require a confirmatory biopsy. It depletes cells in the suspicious area for examination and to ...

Osteolytic bone metastases are frequent in patients with advanced cancer of the breast, lung, and (to a lesser extent) the prostate. Roentgenography, bone scintigraphy, and bone biopsies are commonly used for the early identification and follow-up of these conditions. These methods have though marked shortcomings as they are all static methods giving a picture of the current situation in bone but not telling about rate of changes taking place in bone. Metabolic bone markers have been shown to be a useful tool for monitoring metastatic bone activity.. It has been shown that there are two different pathways of bone resorption: the cathepsin K-mediated pathway, which is active during physiological resorption of bone, and the matrix metalloproteinase pathway, which functions mainly in pathological situations. ICTP specifically reflects matrix metalloproteinase-mediated pathological degradation of bone collagen (1, 2). ICTP is thus a highly specific marker of bone degradation in bone metastasis and ...

BACKGROUND: Cancer-induced bone pain (CIBP) is a severe chronic pain that is less than adequately controlled by conventional analgesics. Prostatic acid phosphatase (PAP) has been considered as a diagnostic marker for prostate cancer and its transmembrane isoform has been reported to play an antinociceptive effect in neuropathic and inflammatory pain. However, it remains unknown whether it has an analgesic effect on CIBP and what are the underlying mechanisms.. OBJECTIVE: In the present study, we tested whether PAP could alleviate the pain symptoms induced by bone cancer in a rat model.. STUDY DESIGN: A randomized, double blind, and controlled rat animal trial.. METHODS: We first established a rat CIBP model and observed the spinal expression of PAP by immunofluorescence histochemistry and Western blot. Then, PAP (0.1, 0.3, or 1 μg) was intrathecally administered in the CIBP rats in a repeated manner from 15 to 18 days (once per day) after inoculation of tumor cells. On postoperative day (POD) ...

N2 - Cyclin-dependent kinase 2 (CDK2) has been reported to be essential for cell proliferation in several human tumours and it has been suggested as an appropriate target to be considered in order to enhance the efficacy of treatment regimens based on the use of DNA damaging drugs. We evaluated the clinical impact of CDK2 overexpression on a series of 21 high-grade osteosarcoma (OS) samples profiled by using cDNA microarrays. We also assessed the in vitro efficacy of the CDKs inhibitor roscovitine in a panel of drug-sensitive and drug-resistant human OS cell lines. OS tumour samples showed an inherent overexpression of CDK2, and high expression levels at diagnosis of this kinase ...

Limb salvage surgery has become the standard treatment for malignant primary bone tumors in the extremities. Limb salvage represents a challenge in skeletally immature patients. Several treatment options are available for limb reconstruction after tumor resection in children. We report our results using the technique of epiphyseal sparing and reconstruction with frozen autograft bone in 18 children. The mean follow-up period for the all patients included in this study is 72 ± 26 m. Eight patients remained disease-free, seven patients lived with no evidence of disease, two were alive but with disease, and one patient died of the disease. Five- and ten-year rates of survival were 94.4%. Graft survival at 5 and 10 years was 94.4%. Functional outcome using the Enneking scale was excellent in 17 patients (94.4%) and poor in one patient (5.5%). Complications include 2 nonunions, 2 fractures, 2 deep infections, 1 soft tissue recurrence, and leg length discrepancy in 7 cases.

AIM Since the introduction of chemotherapy, survival in localised high-grade osteosarcoma has improved considerably. However, there is still no worldwide consensus on a standard chemotherapy approach. In this systematic review evidence for effectiveness of each single drug and the role of response guided salvage treatment of adjuvant chemotherapy are addressed, whereas in a meta-analysis the number of drugs in current protocols is considered. METHODS A systematic literature search for clinical studies in localised high-grade osteosarcoma was undertaken, including both randomised and non-randomised trials. Historical clinical studies from the pre-chemotherapy era were included for comparison purposes. RESULTS Nine historical studies showed a long-term survival of 16% after only local treatment. Fifty single agent phase II studies showed high response rates for adriamycin (A, 43%), ifosfamide (Ifo, 33%), methotrexate (M, 32%), cisplatin (P, 26%) but only 4% for etposide (E). In 19 neo-adjuvant studies

Osteosarcoma is among the most frequently occurring primary bone tumors, primarily affecting adolescents and young adults. Despite improvements in osteosarcoma treatment, more specific molecular targets are needed as potential therapeutic options. One target of interest is α-Ca2+/calmodulin-dependent protein kinase II (α-CaMKII), a ubiquitous mediator of Ca2+-linked signaling, which has been shown to regulate tumor cell proliferation and differentiation. Here, we investigate the role of α-CaMKII in the growth and tumorigenicity of human osteosarcoma. We show that α-CaMKII is highly expressed in primary osteosarcoma tissue derived from 114 patients, and is expressed in varying levels in different human osteosarcoma (OS) cell lines [MG-63, N-methyl-N′-nitro-N-nitrosoguanidine (MNNG)/HOS, and 143B). To examine whether α-CaMKII regulates osteosarcoma tumorigenic properties, we genetically inhibited α-CaMKII in two osteosarcoma cell lines using two different α-CaMKII shRNAs delivered by ...

Osteosarcoma (OS) is the most common, non-hematopoietic, primary malignant bone tumor. OS is characterized by its aggressive local growth and systemic dissemination. Although combination of surgical operation and adjuvant chemotherapy greatly improved the prognosis, more than 20% of patients still cannot get long-term survival. Therefore, novel therapeutic approaches should be expected to be developed. Previously, we developed an OS mouse model by overexpressing c-MYC in bone marrow stromal cells derived from Ink4a/Arf knockout mice. We isolated highly tumorigenic cells (designated AXT cells) from tumors after serial transplantation. Inoculation of AXT cells into syngeneic C57BL/6 mice results in the development of lethal OS with metastatic lesions including lung, which pathologically and clinically mimics human osteoblastic osteosarcoma. To obtain the novel therapeutic agents for OS, we performed drug screening using existing drug collections and found that statins strongly suppressed AXT cell ...

In this study, we showed that TGF-β signaling in prostatic fibroblasts contributed to subsequent prostate cancer bone metastasis through paracrine interactions. Conditioned medium prepared from koPFs promoted the early development and growth of prostate cancer mixed bone lesions in the tibiae of mice. This effect was, in part, mediated by elevated expression of cytokines CXCL16 and CXCL1 present in the koPFCM, which stimulated prostate cancer cell adhesion to the bone matrix and induced proliferation at an early stage.. It is well established that stromal TGF-β signaling is important for prostate tissue development as well as prostate cancer initiation and progression (9, 26-29). TGF-β is abundant in the bone matrix, and that the release of TGF-β from the matrix is a critical component for the vicious cycle of osteoclastic bone metastasis (12). Inhibition of TGF-β with small-molecule inhibitors or neutralizing antibodies has previously been shown to decrease osteolytic bone lesion ...

It has also been demonstrated that VEGF regulates both the expression of CXCR4 and invasiveness in breast cancer cell lines. We compared the immunohistochemical expression of CXCR4 and VEGF between the primary site and a concordant pulmonary metastatic site in 30 osteosarcoma patients, all of which had undergone thoracotomy. Microvessel density (MVD) as shown by immunostaining of CD34 and proliferative activity with MIB-1 monoclonal antibody was ...

18 Apr 2017. When cancer metastases, bone unwittingly offers a friendly place for tumour cell growth--only to have its hospitality betrayed by pathologic fractures, spinal cord compression, the need for bone surgery or irradiation, and an increased risk of death.. In the largest-known study on bone metastases in thyroid cancer, researchers at the University of Michigan Comprehensive Cancer Center found that patients with follicular and medullary thyroid cancer had the highest rate of cancer-related bone lesions and fractures and an increased risk of death.. We know that metastases are bad.. But patients in our study who had bone metastases had a worse survival rate compared to patients who had metastases at other distant sites, says Megan Haymart, M.D., assistant professor of medicine at Michigan Medicine and one of the researchers on the study.. This suggests that bone metastases are a uniquely poor prognostic indicator.. However, patients with localised or regional thyroid cancer---without ...

Osteogenic sarcoma (also called osteosarcoma) is the most common tumor of bone. Approximately 1,000 cases of osteogenic sarcoma are seen in the United States each year. A second peak of incidence of osteosarcoma occurs in the eighth decade of life, typically associated with Paget bone disease. Osteosarcoma typically affects adolescents and generally occurs in bones around the knee joint, though any bone of the body can be affected. Treatment typically involves chemotherapy and surgery to try to achieve the best cure rate. Standard drugs include doxorubicin and cisplatin in adults and the same two drugs with high-dose methotrexate in children, adolescents, or young adults.. Recurrences typically occur in the lungs. Surgical removal of lung metastases from a primary osteosarcoma is a standard of care when there is a small number of lung nodules that can be removed safely, and can be associated with a 30-35% cure rate. Osteosarcomas occur commonly in familial syndromes associated with sarcoma, such ...

The present study demonstrates that a high level of YY1 protein expression increases the risk of metastasis (4.69-fold) and poor survival (8.35-fold) in osteosarcoma patients independently of covariates such as age, gender, histotype, and chemonecrosis. We report that the highest range of YY1 expression is a statistically significant prognostic factor setting the 5-year survival rate to 34% in patients with osteosarcoma. These results are in line with literature data and with the tumor necrosis rate which is currently the strongest clinical prognostic factor after chemotherapy [2, 23, 24].. Overall, the molecular complexity of osteosarcoma makes the known prognostic markers of limited utility [12, 25]. A multiple panel of biomarkers in addition to clinical parameters would be useful for predicting prognosis [25]. In this setting, YY1 is the first osteosarcoma marker whose overexpression has been correlated with low metastasis-free and poor overall survival in a higher frequency of cases (61% in ...

Alkaline Phosphatase, serum Bone-specific alkaline phosphatase (BAP.) When alkaline phosphatase is measured, it is actually the sum of the bone-specific and liver-specific components (isoenzymes.) BAP can indicate excess osteoblastic cell activity which may indicate bone metastases. Metra Systems, Inc., says that Bone Alkaline Phosphatase is an osteoblast membrane-bound molecule which is involved in bone formation. Levels of this enzyme are thought to be indicative of the activity of osteoblasts. Another description of AlkPhos is that it is an enzyme that is found on the surface of osteoblasts(the cells that build bone) and as such is used as a serum marker of increased osteoblast activity. Since bone is being added at prostate cancer bone metastases, an increased alkaline phosphatase can mean increased bone met formation. A recent paper by MR Smith et al in Urology discussed BAP and NTx in their role as predictors of skeletal complications in HRPC patients (MR Smith, et al, Urology 70: 315-319, ...

Breast cancer is the second leading cause of cancer-related death in women in the United States. During the advanced stages of disease, many breast cancer patients suffer from bone metastasis. These metastases are predominantly osteolytic and develop when tumor cells interact with bone. In vivo models that mimic the breast cancer-specific osteolytic bone microenvironment are limited. Previously, we developed a mouse model of tumor-bone interaction in which three mouse breast cancer cell lines were implanted onto the calvaria. Analysis of tumors from this model revealed that they exhibited strong bone resorption, induction of osteoclasts and intracranial penetration at the tumor bone (TB)-interface. In this study, we identified and used a TB microenvironment-specific gene expression signature from this model to extend our understanding of the metastatic bone microenvironment in human disease and to predict potential therapeutic targets. We identified a TB signature consisting of 934 genes that were

Cryoablation, a form of low-temperature thermal ablation, has a long history in the treatment of primary and metastatic neoplasms of the kidney, liver, lung, and prostate. Cryoablation is a relatively new technique in the palliative treatment of bone metastases, with the first prospective trial reported in 2006 demonstrating its safety and efficacy.. Argon gas flowing through a sealed probe creates an ice ball due to rapid expansion of the pressurized gas in the sealed probe tip, resulting in a temperature drop to -100C within seconds (Joules-Thomson effect). Helium gas is then used to attain active thawing of the ice ball. The size of the ablation depends on the diameter of the cryoprobe, the length of the uninsulated tip, and the time of freezing.. A single freeze-passive thaw-freeze cycle is performed for 10-5-10 minutes, respectively. Unlike that for RF ablation, the ablation zone in cryoablation can be monitored directly with computed tomography (CT) as a low attenuation elliptical region ...
