Chondrosarcoma
A slowly growing malignant neoplasm derived from cartilage cells, occurring most frequently in pelvic bones or near the ends of long bones, in middle-aged and old people. Most chondrosarcomas arise de novo, but some may develop in a preexisting benign cartilaginous lesion or in patients with ENCHONDROMATOSIS. (Stedman, 25th ed)
Chondrosarcoma, Mesenchymal
A rare aggressive variant of chondrosarcoma, characterized by a biphasic histologic pattern of small compact cells intermixed with islands of cartilaginous matrix. Mesenchymal chondrosarcomas have a predilection for flat bones; long tubular bones are rarely affected. They tend to occur in the younger age group and are highly metastatic. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1456)
Chondroma
A benign neoplasm derived from mesodermal cells that form cartilage. It may remain within the substance of a cartilage or bone (true chondroma or enchondroma) or may develop on the surface of a cartilage (ecchondroma or ecchondrosis). (Dorland, 27th ed; Stedman, 25th ed)
Bone Neoplasms
Tumors or cancer located in bone tissue or specific BONES.
Enchondromatosis
Benign growths of cartilage in the metaphyses of several bones.
Chordoma
A malignant tumor arising from the embryonic remains of the notochord. It is also called chordocarcinoma, chordoepithelioma, and notochordoma. (Dorland, 27th ed)
Myxosarcoma

Skull Base Neoplasms
Neoplasms of the base of the skull specifically, differentiated from neoplasms of unspecified sites or bones of the skull (SKULL NEOPLASMS).
Exostoses, Multiple Hereditary
Hereditary disorder transmitted by an autosomal dominant gene and characterized by multiple exostoses (multiple osteochondromas) near the ends of long bones. The genetic abnormality results in a defect in the osteoclastic activity at the metaphyseal ends of the bone during the remodeling process in childhood or early adolescence. The metaphyses develop benign, bony outgrowths often capped by cartilage. A small number undergo neoplastic transformation.
Neoplasms, Connective and Soft Tissue

Chondromatosis, Synovial
Rare, benign, chronic, progressive metaplasia in which cartilage is formed in the synovial membranes of joints, tendon sheaths, or bursae. Some of the metaplastic foci can become detached producing loose bodies. When the loose bodies undergo secondary calcification, the condition is called synovial osteochondromatosis.
Proteoglycans
Glycoproteins which have a very high polysaccharide content.
Osteochondroma
A cartilage-capped benign tumor that often appears as a stalk on the surface of bone. It is probably a developmental malformation rather than a true neoplasm and is usually found in the metaphysis of the distal femur, proximal tibia, or proximal humerus. Osteochondroma is the most common of benign bone tumors.
Maxillary Neoplasms
Cancer or tumors of the MAXILLA or upper jaw.
Baltimore
Cartilage, Articular

Analysis of acute vascular damage after photodynamic therapy using benzoporphyrin derivative (BPD). (1/542)

Benzoporphyrin derivative monoacid ring A (BPD-MA, verteporfin) is currently under investigation as a photosensitizer for photodynamic therapy (PDT). Since BPD exhibits rapid pharmacokinetics in plasma and tissues, we assessed damage to tumour and muscle microvasculature when light treatment for PDT was given at short times after injection of photosensitizer. Groups of rats with chondrosarcoma were given 2 mg kg(-1) of BPD intravenously 5 min to 180 min before light treatment of 150 J cm(-2) 690 nm. Vascular response was monitored using intravital microscopy and tumour cure was monitored by following regrowth over 42 days. For treatment at 5 or 30 min after BPD injection, blood flow stasis was limited to tumour microvasculature with lesser response in the surrounding normal microvasculature, indicating selective targeting for damage. No acute changes were observed in vessels when light was given 180 min after BPD injection. Tumour regression after light treatment occurred in all animals given PDT with BPD. Long-term tumour regression was greater in animals treated 5 min after BPD injection and least in animals given treatment 180 min after drug injection. The correlation between the timing for vascular damage and cure implies that blood flow stasis plays a significant role in PDT-induced tumour destruction.  (+info)

The EWS/TEC fusion protein encoded by the t(9;22) chromosomal translocation in human chondrosarcomas is a highly potent transcriptional activator. (2/542)

The EWS/TEC gene fusion generated by the t(9;22) chromosomal translocation found in extraskeletal myxoid chondrosarcomas encodes a fusion protein containing the amino-terminal domain of the EWS protein fused to the whole coding sequence of the orphan nuclear receptor TEC. We have compared the DNA-binding and transcriptional activation properties of various TEC isoforms and the corresponding EWS/TEC fusion proteins. Band-shift experiments show that the full-length TEC receptor can efficiently bind the NGFI-B Response Element (NBRE), whereas an isoform lacking the entire carboxyl-terminal domain of the receptor binds much less efficiently the NBRE. Addition of the amino-terminal domain of EWS to either isoforms does not alter significantly their DNA-binding properties to the NBRE. Co-transfection experiments of COS cells and human chondrocytes indicate that whereas TEC moderately activates transcription from a NBRE-containing promoter, the corresponding EWS/TEC fusion protein is a highly potent transcriptional activator of the same promoter, being approximately 270-fold more active than the native receptor. EWS/TEC may thus exert its oncogenic potential in chrondrosarcomas by activating the transcription of target genes involved in cell proliferation.  (+info)

Sulphation heterogeneity in the trisaccharide (GalNAcSbeta1, 4GlcAbeta1,3GalNAcS) isolated from the non-reducing terminal of human aggrecan chondroitin sulphate. (3/542)

We report here the isolation and sulphation isomer analyses of trisaccharides GalNAcS(beta1,4)GlcA(beta1,3)GalNAcS (in which S indicates sulphate) derived from the non-reducing termini of aggrecan chondroitin sulphate. Rat chondrosarcoma and human aggrecans were digested for 1 h at 37 degrees C with 30 micro-units of endo-chondroitinase ABC per microgram of chondroitin sulphate, and trisaccharides were isolated from the digests by ToyoPearl HW40S gel-filtration chromatography. Four trisaccharide species were identified; their sulphation isomer compositions, as determined by digestion with chondroitinase ACII and fluorescence-based ion-exchange HPLC, were GalNAc4Sbeta1,4GlcAbeta1,3GalNAc4S, GalNAc4Sbeta1,4GlcAbeta1,3GalNAc6S, GalNAc4,6Sbeta1,4GlcAbeta1, 3GalNAc4S and GalNAc4,6Sbeta1,4GlcAbeta1,3GalNAc6S. The abundances of such sequences in chondroitin sulphate on aggrecan from normal (foetal to 72 years of age) and from osteoarthritic human knee cartilages were also established. The results showed that non-reducing terminal GalNAc4S or GalNAc4,6S can be linked to either a 4-sulphated or a 6-sulphated disaccharide, suggesting that the sulphation of the last disaccharide might not have a direct effect on the specificity of chondroitin sulphate terminal GalNAc sulphotransferases. Furthermore, for each aggrecan preparation examined, the 4S-to-6S ratio of all chain interior disaccharides was equivalent to that in the last repeating disaccharides at the non-reducing terminus, suggesting that neither chondroitin 4-sulphotransferase nor chondroitin 6-sulphotransferase shows preferential activity near the chain terminus.  (+info)

EXT-mutation analysis and loss of heterozygosity in sporadic and hereditary osteochondromas and secondary chondrosarcomas. (4/542)

Osteochondromas occur as sporadic solitary lesions or as multiple lesions, characterizing the hereditary multiple exostoses syndrome (EXT). Approximately 15% of all chondrosarcomas arise within the cartilaginous cap of an osteochondroma. EXT is genetically heterogeneous, and two genes, EXT1 and EXT2, located on 8q24 and 11p11-p12, respectively, have been cloned. It is still unclear whether osteochondroma is a developmental disorder or a true neoplasm. Furthermore, it is unclear whether inactivation of both alleles of an EXT gene, according to the tumor-suppressor model, is required for osteochondroma development, or whether a single EXT germline mutation acts in a dominant negative way. We therefore studied loss of heterozygosity and DNA ploidy in eight sporadic and six hereditary osteochondromas. EXT1- and EXT2-mutation analysis was performed in a total of 34 sporadic and hereditary osteochondromas and secondary peripheral chondrosarcomas. We demonstrated osteochondroma to be a true neoplasm, since aneuploidy was found in 4 of 10 osteochondromas. Furthermore, LOH was almost exclusively found at the EXT1 locus in 5 of 14 osteochondromas. Four novel constitutional cDNA alterations were detected in exon 1 of EXT1. Two patients with multiple osteochondromas demonstrated a germline mutation combined with loss of the remaining wild-type allele in three osteochondromas, indicating that, in cartilaginous cells of the growth plate, inactivation of both copies of the EXT1 gene is required for osteochondroma formation in hereditary cases. In contrast, no somatic EXT1 cDNA alterations were found in sporadic osteochondromas. No mutations were found in the EXT2 gene.  (+info)

Chemical modification and site-directed mutagenesis of conserved HXXH and PP-loop motif arginines and histidines in the murine bifunctional ATP sulfurylase/adenosine 5'-phosphosulfate kinase. (5/542)

The sulfurylase domain of the mouse bifunctional enzyme ATP sulfurylase/adenosine 5'-phosphosulfate (APS) kinase contains HXXH and PP-loop motifs. To elucidate the functional importance of these motifs and of conserved arginines and histidines, chemical modification and site-directed mutagenesis studies were performed. Chemical modification of arginines and histidines with phenylglyoxal and diethyl pyrocarbonate, respectively, renders the enzyme inactive in sulfurylase, kinase, and overall assays. Data base searches and sequence comparison of bifunctional ATP sulfurylase/APS kinase and monofunctional ATP sulfurylases shows a limited number of highly conserved arginines and histidines within the sulfurylase domain. Of these conserved residues, His-425, His-428, and Arg-421 are present within or near the HXXH motif whereas His-506, Arg-510, and Arg-522 residues are present in and around the PP-loop. The functional role of these conserved residues was further studied by site-directed mutagenesis. In the HXXH motif, none of the alanine mutants (H425A, H428A, and R421A) had sulfurylase or overall activity, whereas they all exhibited normal kinase activity. A slight improvement in reverse sulfurylase activity (<10% residual activity) and complete restoration of forward sulfurylase was observed with R421K. Mutants designed to probe the PP-loop requirements included H506A, R510A, R522A, R522K, and D523A. Of these, R510A exhibited normal sulfurylase and kinase activity, R522A and R522K showed no sulfurylase activity, and H506A had normal sulfurylase activity but produced an effect on kinase activity (<10% residual activity). The single aspartate, D523A, which is part of the highly conserved GRD sequence of the PP-loop, affected both sulfurylase and kinase activity. This mutational analysis indicates that the HXXH motif plays a role only in the sulfurylase activity, whereas the PP-loop is involved in both sulfurylase and kinase activities. Residues specific for sulfurylase activity have also been distinguished from those involved in kinase activity.  (+info)

Up-regulation of MDC15 (metargidin) messenger RNA in human osteoarthritic cartilage. (6/542)

OBJECTIVE: The aim of the study was to investigate the messenger RNA (mRNA) expression of the disintegrin metalloproteinase MDC15 (metargidin, or ADAM-15) in normal and osteoarthritic (OA) articular cartilage. METHODS: In situ hybridization experiments and reverse transcription-polymerase chain reaction (RT-PCR) were performed on tissue samples of adult normal and OA articular cartilage. RESULTS: MDC15 mRNA could be detected in normal articular cartilage by RT-PCR using tissue-extracted total RNA as a template. However, the mRNA level remained below the sensitivity of in situ hybridization. In contrast, in situ hybridizations of OA cartilage revealed an intense staining with the MDC15-specific riboprobes. The extension of the analysis to chondrosarcomas showed a strong up-regulation of MDC15 mRNA in these malignant transformed cells. CONCLUSION: Our results demonstrate a markedly strong up-regulation of MDC15 in adult OA and neoplastic cartilage compared with adult normal articular cartilage, indicating a potential role of the disintegrin metalloproteinase in cartilage remodeling.  (+info)

Reconstruction and limb salvage after resection for malignant bone tumour of the proximal humerus. A sling procedure using a free vascularised fibular graft. (7/542)

We assessed the intermediate functional results of eight patients after wide resection of the proximal humerus for malignant bone tumour. We used a free vascularised fibular graft as a functional spacer and a sling procedure to preserve passive scapulohumeral movement. Scapulohumeral arthrodesis was not carried out. Five patients had osteosarcoma, two achondrosarcoma and one a malignant fibrous histiocytoma of the bone. The mean duration of follow-up was 70 months (median, 76) for the seven patients who were still alive at the time of the latest follow-up. One patient died from the disease 12 months after surgery. There were no local recurrences. The functional results were described and graded quantitatively according to the rating system of the Musculoskeletal Tumour Society. Our results were satisfactory with regard to pain, emotional acceptance and manual dexterity. Function and lifting ability were unsatisfactory in two patients. One patient had delayed union between host and graft, but this united after six months without further surgery. Radiographs of the shoulder showed absorption or collapse of the head of the fibula in four of the eight patients and a fracture in another. No functional problems related to absorption or fracture of the head of the fibula were noted. There was no infection or subluxation of the head. We conclude that this is a reasonably effective technique of limb salvage after resection of the proximal humerus.  (+info)

Fusion of the EWS-related gene TAF2N to TEC in extraskeletal myxoid chondrosarcoma. (8/542)

Extraskeletal myxoid chondrosarcomas (EMCs) are characterized by a recurrent t(9;22)(q22;q12) translocation, resulting in the fusion of the EWS gene in 22q12 and the TEC gene in 9q22. Here we report that a third member of the EWS, TLS/FUS gene family, TAF2N, can replace EWS as a fusion partner to TEC in EMC. Two tumors, one with a novel t(9;17)(q22;q11) variant translocation and one with an apparently normal karyotype, expressed TAF2N-TEC fusion transcripts. In both cases, the chimeric transcripts were shown to contain exon 6 of TAF2N fused to the entire coding region of TEC. This transcript is structurally and functionally very similar to the EWS-TEC fusions. The exchange of the EWS NH2-terminal part with the TAF2N NH2-terminal part in EMC further underscores the oncogenic potential of these protein domains as partners in fusion genes.  (+info)

Chondrosarcoma is a type of highly malignant tumor with a potent capacity to invade locally and cause distant metastasis. Chondrosarcoma shows a predilection for metastasis to the lungs. Interleukin-8 (IL-8), a chemokine with a defining CXC amino acid motif, is known to possess tumorigenic and proangiogenic properties. Over-expression of IL-8 has been detected in many human tumors. However, the effects of IL-8 in migration and integrin expression in chondrosarcoma cells are largely unknown. In this study, we found that IL-8 increased the migration and the expression of αvβ3 integrin in human chondrosarcoma cells. Activations of phosphatidylinositol 3-kinase (PI3K), Akt, and AP-1 pathways after IL-8 treatment were demonstrated, and IL-8-induced expression of integrin and migration activity was inhibited by the specific inhibitor and mutant of PI3K, Akt, and AP-1 cascades. Taken together, our results indicated that IL-8 enhances the migration of chondrosarcoma cells by increasing αvβ3 integrin ...

Intracellular proteoglycan core protein precursor was purified from cell lysates by immunoprecipitation with polyclonal antibodies against the hyaluronic acid-binding region, followed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The core precursor was eluted from the gels and treated with alkaline borohydride in order to convert serine residues substituted with xylose or N-acetylgalactosamine to alanine (or with alkaline sulfite to convert them to cysteic acid). After acid hydrolysis, the proportions of labeled serine and alanine (or cysteic acid) were determined by high performance liquid chromatography, and the results were compared with those obtained for the completed proteoglycan molecules isolated from the same cultures. In the completed proteoglycans, about 55% of the serine residues were substituted ...

OBJECTIVE: To determine whether, in human fibroblasts and chondrosarcoma cells, the regulation of interleukins (IL)-6, 8, and 11 and matrix metalloproteinases (MMP)-1, 3, and 13, and their tissue inhibitor TIMP-1, depends on the transcription factor nuclear factor-kappaB (NF-kappaB). METHODS: Fibroblasts and chondrosarcoma cells were effectively infected with an adenovirus encoding human IkappaBalpha, and inhibition of NF-kappaB function was observed. The induction of MMP and IL-6, 8, and 11 by various stimuli was assessed by ELISA. RESULTS: The induction of IL-6 and IL-8 clearly depended on NF-kappaB in both fibroblasts and chondrosarcoma cells, irrespective of stimulus, but IkappaBalpha overexpression had little effect on IL-11. MMP-1, -3, and -13 were also inhibited, but TIMP-1 was unaffected. CONCLUSION: NF-kappaB appears to play an important and selective role in MMP induction in human fibroblasts and chondrosarcoma cells. This suggests there are NF-kappaB dependent mechanisms of cartilage ...

Cyclooxygenase (COX)-2, the inducible isoform of prostaglandin (PG) synthase, has been implicated in tumor metastasis. Interaction of COX-2 with its specific EP receptors on the surface of cancer cells has been reported to induce cancer invasion. However, the effects of COX-2 on migration activity in human chondrosarcoma cells are mostly unknown. In this study, we examined whether COX-2 and EP interaction are involved in metastasis of human chondrosarcoma. We found that over-expression of COX-2 or exogenous PGE2 increased the migration of human chondrosarcoma cells. We also found that human chondrosarcoma tissues and chondrosarcoma cell lines had significant expression of the COX-2 which was higher than that in normal cartilage. By using pharmacological inhibitors or activators or genetic inhibition by the EP receptors, we discovered that the EP1 receptor but not other PGE receptors is involved in PGE2-mediated cell migration and α2β1 integrin expression. Furthermore, we found that human

Human chondrosarcomas do not respond to current chemotherapies or radiation therapy, and their size and histological appearance do not reliably predict the risk of local recurrence and metastases, making selection of surgical treatment difficult. Identifying mechanisms responsible for the proliferation and invasive behavior of these tumors would be of immense clinical value. We hypothesized that telomerase expression is one of these mechanisms. We detected telomerase expression in 7 of 16 chondrosarcomas, but cells cultured from telomerase-negative chondrosarcomas acquired strong telomerase activity and lost tumor suppressor activity after their establishment in culture. These changes were associated with accelerated indefinite cell proliferation, morphological transition, and increased invasive activity, indicating that telomerase activation and loss of cell cycle control leads to the emergence of aggressive cells from chondrosarcoma cell populations. These observations may lead to better ...

In this study, we investigated the anticancer effects of a new benzimidazole derivative, 1-benzyl-2-phenyl -benzimidazole (BPB), in human chondrosarcoma cells. BPB-mediated apoptosis was assessed by the MTT assay and flow cytometry analysis. The in vivo efficacy was examined in a JJ012 xenograft model. Here we found that BPB induced apoptosis in human chondrosarcoma cell lines (JJ012 and SW1353) but not in primary chondrocytes. BPB induced upregulation of Bax, Bad and Bak, downregulation of Bcl-2, Bid and Bcl-XL and dysfunction of mitochondria in chondrosarcoma. In addition, BPB also promoted cytosolic releases AIF and Endo G. Furthermore, it triggered extrinsic death receptor-dependent pathway, which was characterized by activating Fas, FADD and caspase-8. Most importantly, animal studies revealed a dramatic 40% reduction in tumor volume after 21 days of treatment. Thus, BPB may be a novel anticancer agent for the treatment of chondrosarcoma.

Clear cell chondrosarcoma is a rare tumor that can be easily confused with benign tumors. The aim of this report is to present a case that is rare, initially diagnosed as aneurysmal bone cyst and then chondroblastoma, and has an interesting extension pattern. A 41-year-old male patient was treated for an apparently benign cystic lesion of the right proximal femur by intralesional excision and bone grafting. The pathological diagnosis was aneurysmal bone cyst. Two years later, the patient presented with a pathological fracture at the same site and a total hip arthroplasty was performed. The pathological specimen was diagnosed as chondroblastoma. Three years later, clinical and radiological examination of the patient revealed a large mass located on the intrapelvic side of the acetabulum. There was no evidence of distant metastases. Both tumors were resected with a wide margin on the femoral side and a marginal margin on the intrapelvic side. The extremity was reconstructed with a resection-type ...

Functional genomic analyses of the impact of global hypomethylation an by Christopher Allan HammFunctional genomic analyses of the impact of global hypomethylation an by Christopher Allan Hamm
Chondrosarcomas are malignant cartilage tumors that do not respond to traditional chemotherapy or radiation. The 5-year survival rate of histologic grade III chondrosarcoma is less than 30%. To achieve a greater understanding of chondrosarcoma tumorigenesis, a model for human chondrosarcoma has been established in a rat system. The model, known as the Swarm rat chondrosarcoma (SRC), resembles human chondrosarcoma and provides a system to study tumor growth and progression. Here we examined the influence of the tumor microenvironment and the impact of genome-wide hypomethylation on the behavior of SRC tumors, two factors known to contribute fundamentally to the development and progression of solid tumors. Previous studies with SRC revealed that tumor microenvironment can significantly influence chondrosarcoma malignancy, but the underlying biologic mechanisms have not been defined. To address this issue we carried out epigenetic and gene expression studies on the SRC tumors that were initiated at

Primary chondrosarcoma of the breast, although very rare, has been reported previously.1 An extensive review of 132 636 cases of breast cancer between 1973 and 1998, in the Netherlands,2 identified 34 cases of concurrent breast cancer and cartilaginous tumours. There were 28 osteochondromas in the same group as well but a statistically similar incidence of concurrent osteochondromas was observed in patients with lung cancer. Out of the 34 cases, 18 were enchondromas and 15 chondrosarcomas, and involved mostly the femur or humerus (65%). All 34 had histological and immunohistochemical survey performed and cluster analysis did not reveal any associations with known syndromes or genetic traits. Their findings support the existence of a new hitherto unrecognised syndrome, characterised by an increased risk to develop breast cancer and also centrally originating cartilaginous tumours. There have been sporadic reports of concurrent breast carcinoma as well as bone chondrosarcoma in the literature.3 ...

ChondrosarcomaChondrosarcoma
Imaging studies - including radiographs (x-rays), computerized tomography (CT), and magnetic resonance imaging (MRI) - are often used to make a presumptive diagnosis of chondrosarcoma. However, a definitive diagnosis depends on the identification of malignant cancer cells producing cartilage in a biopsy specimen that has been examined by a pathologist. In a few cases, usually of highly anaplastic tumors, immunohistochemistry (IHC)is required.. There are no blood tests currently available to enable an oncologist to render a diagnosis of chondrosarcoma. The most characteristic imaging findings are usually obtained with CT.. Nearly all chondrosarcoma patients appear to be in good health. Often, patients are not aware of the growing tumor until there is a noticeable lump or pain. Earlier diagnosis is generally accidental, when a patient undergoes testing for another problem and physicians discover the cancer. Occasionally the first symptom will be a broken bone at the cancerous site. Any broken ...

Chondrosarcoma - CowChondrosarcoma - Cow
Chondrosarcoma are a relatively rare neoplasia observed in cattle. The disease involves neoplastic changes to chondrocytes involved with cartilage growth, maintenance and remodeling of cartilage. In abattoir surveys, the frequency of malignant or benign cartilaginous neoplasms in cattle has been found to be less than 1% of all neoplasms[1]. The cause of this disease is unknown but likely to involve genetics. Chondrosarcoma usually affect axial bones rather than appendicular ones, and flat bones are involved more often than long bones. Chondrosarcoma have been commonly reported in the scapula of cattle with no apparent breed predilection[2]. Other sites include the nasal turbinates[3] and extraskeletal sites such as the mesenchyme[4]. Lameness is usually the first presenting clinical sign, and as the condition worsens, obvious swelling around the tumour becomes apparent. In tumours involving the nasal turbinates, a nasal discharge and dyspnea may be apparent. Diagnosis can only be made after ...

A Study Of Chondrosarcoma, Bone And Cartilage Derived Cancer - Natural Height GrowthA Study Of Chondrosarcoma, Bone And Cartilage Derived Cancer - Natural Height Growth
As for the genetics and causes of the cancer, it has been rather hard to find sources which can determine the cause of it, from the website…. The genetic changes specific to chondrosarcoma continue to be investigated extensively. Although studies have not yet established a specific or recurrent karyotypic feature for any of these tumors, different chondrosarcomas have demonstrated anomalies in several tumor suppressor genes, oncogenes, and transcription factors, including TP53, RAS, EXT1, EXT2, and Sox9. Available cytogenetic and comparative genomic hybridization (CGH) studies reveal changes in some chondrosarcomas, but fail to do so in others. These studies are thus far difficult to interpret.. Based on the available studies, it is likely that chondrosarcomas are generated by a coordinated, multi-step process involving primarily tumor suppressor genes. In fact, the complexity and variety of genetic changes seen in chondrosarcomas may indicate several distinct genetic pathways. Some of the ...

Lirias: Intramuscular mixed tumour with clonal chromosomal changesLirias: Intramuscular mixed tumour with clonal chromosomal changes
A case of an entirely intramuscular mixed tumour occurred in an 82-year-old man, who presented with a large mass in the region of the right triceps muscle. A lobulated tumour was seen, with plump, round epithelioid cells embedded in a chondromyxoid stroma. Immunohistochemical examination showed strong S100 protein and pancytokeratin positivity in most of the tumour cells. Cytogenetic analysis revealed complex clonal chromosomal changes: 47, XY, +i(2) (q10), -15, der(17) t(15; 17) (q11; p12), +r. Differential diagnosis against extraskeletal myxoid chondrosarcoma (EMC) may be problematic, particularly in an incisional biopsy. Chromosomal analysis can be very helpful in solving this problem, since EMC shows a specific reciprocal chromosome translocation characterised as t (9;22) (q22-31) (q11-12 ...

Purpose: Chondrosarcomas are notoriously resistant to cytotoxic chemotherapeutic agents. We sought to identify critical signaling pathways that contribute to their survival and proliferation, and which may provide potential targets for rational therapeutic interventions. Experimental Design: Activation of receptor tyrosine kinases (RTKs) was surveyed using phospho-RTK arrays. S6 phosphorylation and NRAS mutational status were examined in chondrosarcoma primary tumor tissues. Small interfering RNA or small molecule inhibitors against RTKs or downstream signaling proteins were applied to chondrosarcoma cells and changes in biochemical signaling, cell cycle, and cell viability were determined. In vivo anti-tumor activity of BEZ235, a phosphoinositide-3-kinase (PI3K)/mammalian target of rapamycin (mTOR) inhibitor, was evaluated in a chondrosarcoma xenograft model. Results: Several RTKs were identified as critical mediators of cell growth, but the RTK dependencies varied among cell lines. In ...

Chondrosarcoma of the Thorax - Semantic ScholarChondrosarcoma of the Thorax - Semantic Scholar
Although a rare entity, chondrosarcoma is the most common malignant tumor of the chest wall. Most patients present with an enlarging, painful anterior chest wall mass arising from the costochondrosternal junction. CT scan with intravenous contrast is the gold standard radiographic study for diagnosis and operative planning. Contrary to previous dictum, resection may be performed in an appropriate surgical candidate based on imaging characteristics or image-guided percutaneous biopsy results; incisional biopsy is rarely required. The keys to successful treatment are early recognition and radical excision with adequate margins, as chondrosarcoma is relatively resistant to radiotherapy and conventional cytotoxic chemotherapy. Overall survival is excellent in most surgical series from experienced centers. Complete excision with widely negative microscopic margins at the initial operation is of the utmost importance, as local recurrence portends systemic metastasis and eventual tumor-related mortality.

BACKGROUND: notch receptors are critical determinants of cell fate in a variety of organisms. Notch signaling is involved in the chondrogenic specification of neural crest cells. Aberrant Notch activity has been implicated in numerous human diseases including cancers; however its role in chondrogenic tumors has not been clarified. METHOD: tissue samples from a case of primary chondrosarcoma of the maxilla and its recurrent tumor were examined immunohistochemically for Notch1-4 and their ligands (Jagged1, Jagged2 and Delta1) expression. RESULTS: both primary and recurrent tumors were histopathologically diagnosed as conventional hyaline chondrosarcoma (WHO Grade I). Hypercellular tumor areas strongly expressed Notch3 and Jagged1 in spindle and pleomorphic cells suggesting up-regulation of these protein molecules at sites of tumor proliferation. Expression patterns were distinct with some overlap. Differentiated malignant and atypical chondrocytes demonstrated variable expression levels of ...

Week 257: Case 2 | Johns Hopkins Surgical Pathology Unknown ConferenceWeek 257: Case 2 | Johns Hopkins Surgical Pathology Unknown Conference
Answer: Chondrosarcoma. Histology: none provided. Discussion: Chondrosarcomas are malignant proliferations of cartilage which tend to occur in the axial skeleton of older people. The radiograph in this case is helpful to diagnose a malignant tumor because of its destructive and aggressive permeative pattern. Histologically the cartilage shows atypical nuclei and a permeative growth pattern around native trabeculae. This permeative growth pattern is diagnostic of malignancy in most primary bone tumors. The radiograph, however, is a most important tool leading to the diagnosis of chondrosarcoma.. Although metastatic carcinoma is the most common bone tumor in this age group, there is no evidence of epithelial cells in this case.. Enchondromas occasionally occur in the pelvis. Occasionally, the cartilage of enchondroma can show atypia. However, the destructive and aggressive radiographic pattern precludes the diagnosis of an enchondroma. Therefore, the radiograph should always be consulted when ...

Depending on the type of chondrosarcoma, it may spread slowly or very rapidly. Its presently unknown what causes this type of cancer. This is partially because it is so unusual that there are not a lot of cases to study. A higher incidence of nasal CSAs among cats living in urban areas may indicate a link to air pollution. The type affecting bones has been found to contain viruses in the cells of the tumor, suggesting a viral connection. Some bone tumors develop on the site of a previous fracture, which may mean theres a link with the bodys cells that heal a broken bone.

Magnetic resonance imaging demonstrated a large, intensely enhancing extra-axial mass, which appeared to originate from the right side of the falx cerebri with significant mass effect. A presumptive diagnosis of meningioma was made. INTERVENTION: The patient underwent preoperative embolization of the lesion ...

Myxofibrosarcoma (MFS) is characterized by abundant myxoid stroma, a wide spectrum of cytological atypia, and frequent local recurrence. Some soft tissue tumors with myxoid stroma can histologically mimic MFS, but have different biological behaviors. Here we sought to identify a useful diagnostic marker for MFS. After our analysis of the gene expression dataset from the Gene Expression Omnibus database, we focused on claudin 6 (CLDN 6). The status of CLDN 6 was assessed by immunohistochemistry in 61 samples of MFS and other (benign) myxoid soft tissue tumors (28 myxoma samples, 12 nodular fasciitis samples), 18 low-grade fibromyxoid sarcoma, 30 myxoid liposarcoma, 29 extraskeletal myxoid chondrosarcoma and 27 dedifferentiated liposarcoma with myxoid feature samples ...

BACKGROUND: The finding of a cytogenetic-pathologic correlation between complex karyotypes and high grade cartilaginous tumors has been reported. However, few cytogenetic reports exist regarding benign or low grade lesions. A subset of low grade malignant cartilaginous tumors is characterized by locally aggressive behavior but no metastatic potential. Because the histopathologic distinction between benign, borderline, or low grade malignant cartilaginous lesions can be difficult, the finding of additional tumor markers associated with the clinical behavior of borderline cartilaginous lesions could be clinically significant.. METHODS: Four cartilaginous tumors, including an osteochondroma (OC), a chondromyxoid fibroma (CF), an enchondroma (EC), and a dedifferentiated chondrosarcoma (DCS), were cultured and harvested using short term, in situ culture techniques. Chromosome analysis was performed by conventional G-banding and fluorescence in situ hybridization was used to confirm ...

Chondroid tumors are predominantly lesions of the axial skeleton but can infrequently have an extraskeletal origin. Primary intracranial chondrosarcomas constitute ,0.16% of all brain tumors, an overwhelming majority of which are skull base tumors (1, 2). They are thought to arise from undifferentiated cells from cartilaginous synchondroses (1-3, 6, 7). Much less common sites include the falx, choroid plexus, and convexity. The histogenesis at this site is uncertain but is thought to arise from the pluripotent cells of the meninges.. Primary chondrosarcomas can be classified as mesenchymal, myxoid, or classical based on their cytoarchitecture. In the series published by Korten et al (2), which included 15 case reports plus 177 cases from a review of the literature, no sex dominance was shown. Ages varied from 3 months to 76 years, with a mean age of 37 years. Considering the rarity of occurrence of intracranial chondrosarcomas, it was difficult to establish a clear demographic pattern; however, ...

TBX3, a member of the T-box family of transcription factors, is essential in development and has emerged as an important player in the oncogenic process. TBX3 is overexpressed in several cancers and has been shown to contribute directly to tumour formation, migration and invasion. However, little is known about the molecular basis for its role in development and oncogenesis because there is a paucity of information regarding its target genes. The cyclin-dependent kinase inhibitor p21WAF1 plays a pivotal role in a myriad of processes including cell cycle arrest, senescence and apoptosis and here we provide a detailed mechanism to show that it is a direct and biologically relevant target of TBX3. Using a combination of luciferase reporter gene assays and in vitro and in vivo binding assays we show that TBX3 directly represses the p21WAF1 promoter by binding a T-element close to its initiator. Furthermore, we show that the TBX3 DNA binding domain is required for the transcriptional repression of p21WAF1

In most cases, an x-ray examination is sufficient to determine the diagnosis, but not always.. Biopsy : taking a sample of bone tissue for morphological examination. It is considered the most reliable method of investigation. The procedure is quite painful, and some veterinarians refuse to perform a biopsy with obvious signs of a bone tumor obtained by radiography. With a controversial interpretation of the results of the examination, a biopsy allows you to make a final diagnosis.. Sometimes, around the tumor develops a significant inflammatory process and requires several samples of pathological tissue. Taking samples is not dangerous and does not lead to the formation of a pathological fracture.. Also check out Osteosarcoma causes and symptoms on credihealth.. If this is not an osteosarcoma?.

Chondrosarcoma of Bone | LUMCChondrosarcoma of Bone | LUMC
Chondrotumors of bone are the most frequent bone tumors. The majority is asymptomatic and recognised by accident. In the long bones the incidence of low grade sarcoma is regardless the radiological findings very common. Because the incidence of metastasis in these low grade tumors is extremely low research is undertaken to find the treatment with minimal surgery and a high chance of cure. Application of local adjuvant (phenol / alcohol) on a cartilage cell layer is tested in vitro studies. The clinical application in combination with curettage and adjuvant is followed in an at random group of patients. The goal is to establish the recurrences and complications and change in grading by follow up for many years clinically, histology if available and by dynamic MRI. The second part of this study is the study for Ollier disease in the major centres devoted to bone tumors in Europe all members of the EMSOS. The collected data are screened for incidence, presentation and malignant transformation as ...
