AU - Nicoletti, G.. AU - Prodi, G.. AU - Scotlandi, K.. AU - Nanni, P.. PY - 1989. Y1 - 1989. N2 - The effect of various antineoplastic drugs (1-β-D-arabinofuranosylcytosine, 5-azacytidine, cisplatin, dactinomycin, epirubicin, vincristine, and the activated metabolite of cyclophosphamide, mafosfamide) on cell differentiation in vitro was investigated using a human alveolar rhabdomyosarcoma cell clone, RMZ-RC2. These cells are able to differentiate spontaneously from small mononuclear proliferating elements to terminal, extremely elongated multinuclear structures resembling myotubes; morphological differentiation is accompanied by the expression of myosins, in particular the embryonic isoform, which is used in this study as a specific marker of myogenic differentiation. The proportion of differentiated ...

There is a constant need of features able to characterize potentially metastatic cells among the heterogeneous cell subpopulations which constitute a tumor. Image cytometry of metastatic tumor cells give rise to variable results, partly because of a heterogeneous origin of cells, or potential drug effects. The aim of this work was to characterize nuclear changes observed in metastatic cell clones issued in vitro from the same parental cell population The nuclear phenotypes of 6 cell sublines isolated from a rat rhabdomyosarcoma cell line and differing in their metastatic ability were evaluated by image cytometry on Feulgen-stained preparations. Densitometric [5], geometric [3] and textural [9] features were computed from each nuclear image. For each cell subline, a metastatic score, ranging from 0 to 10, was calculated on the basis of in vivo invasivity data, by measuring the number of pulmonary metastases observed after s.c. graft of tumor cells in rats. Data obtained were compared to ...

The International Classification of Rhabdomyosarcoma includes botryoid and spindle cell RMS as superior-risk groups, embryonal RMS as an intermediate-risk group, and alveolar RMS as an unfavorable-risk group. The 2013 World Health Organization (WHO) classification of skeletal muscle tumors modified the histologic classification of RMS to include sclerosing RMS as a type of spindle cell RMS separate from embryonal RMS. The current WHO classification ...

Childhood rhabdomyosarcoma is a disease in which malignant (cancer) cells form in muscle tissue. Rhabdomyosarcoma is a type of sarcoma. Sarcoma is cancer of soft tissue (such as muscle), connective tissue (such as tendon or cartilage), or bone. Rhabdomyosarcoma usually begins in muscles that are attached to bones and...

Neoplastic meningitis can result from leptomeningeal dissemination of a variety of cancers. We now report the development of animal models of human neoplastic meningitis and activity of intrathecal 4-hydroperoxycyclophosphamide (4-HC) against the human rhabdomyosarcoma cell line 11 -671 and the human glioma cell line D-54 MG grown in the subarachnoid space of athymic rats. The injection of 5 x IO II-67I or D-54 MG cells resulted in leptomeningeal tumor growth from the base of the brain to the cauda equina. Daily weights and neurological exami nations revealed progressive neurological deficits and weight loss, with death occurring between Days 21 and 27 for II,-671 and Days 14 and 26 for D-54 MG. 4-HC toxicity in non-tumor-bearing rats was assessed at dose levels of 2.0,10.0,15.0, and 20.0 HIM,with clinical and histolÃ3gica! evidence of neurotoxicity observed at the 2 highest dose levels. Intrathecal treatment with 4-HC on Day 8 following injection of TE-671 resulted in an increase in median survival

The risk of myopathy and rhabdomyolysis is considerably increased in statin users with end-stage renal failure (ESRF). Uremic toxins, which accumulate in patients with ESRF, exert cytotoxic effects that are mediated by various mechanisms. Therefore, accumulation of uremic toxins might increase statin-induced cytotoxicity. The purpose of this study was to determine the effect of four uremic toxins-hippuric acid, 3-carboxy-4-methyl-5-propyl-2-furanpropionate, indole-3-acetic acid, and 3-indoxyl sulfate-on statin-induced myopathy. Differentiated rhabdomyosarcoma cells were pre-treated with the uremic toxins for seven days, and then the cells were treated with pravastatin or simvastatin. Cell viability and apoptosis were assessed by viability assays and flow cytometry. Pre-treatment with uremic toxins increased statin- but not cisplatin-induced cytotoxicity (p < 0.05 vs. untreated). In addition, the pre-treatment increased statin-induced apoptosis, which is one of the cytotoxic factors (p < 0.05

Tumors that grow in the active muscles of the body are called rhabdomyosarcoma. They occur in the head, neck, and pelvis, arms, or legs. The two most common types of Rhabdomyosarcoma are Embryonal Rhabdomyosarcoma. Found in children under 15, commonly in the head and neck region and genitourinary tract. Alveolar Rhabdomyosarcoma. A very aggressive, rare tumor that involves the muscles of the extremities or trunk. The most least common form of Rhabdomyosarcoma: Botryoid Rhabdomyosarcoma: A variant of the embryonal type arising as a grape-like lesion in mucosal-lined hollow organs such as the vagina and urinary bladder. Pleomorphic Rhabdomyosarcoma: Seen primarily in adults and arises in muscles of the extremities.

TY - JOUR. T1 - In Situ Selection of a Human Rhabdomyosarcoma Resistant to Vincristine with Altered β-Tubulins. AU - Houghton, Janet A.. AU - Houghton, Peter J. AU - Hazelton, Bonni J.. AU - Douglass, Edwin C.. PY - 1985/6/1. Y1 - 1985/6/1. N2 - In order to simulate more closely conditions in which resistance to vincristine (VCR) is selected in human solid tumors, a human rhabdomyosarcoma grown as a xenograft in immune-deprived mice has been selected for resistance in situ. Karyotype analysis showed the resistant line, HxRh18/VCR-3, to have a diploid modal number, with no apparent translocations, whereas the predominant population in the parental, sensitive HxRh18 xenograft demonstrated a modal number near-tetrapbid with many marker chromosomes. From the rapid rate at which resistance was selected and from karyotypic evidence, data strongly suggest that HxRh18/VCR-3 was a subpopulation within the parent tumor. When grown in the same host, HxRh18/VCR-3 tumors accumulated less drug, and the rate ...

The accumulation of weakly basic drugs into acidic organelles has recently been described as a contributor to resistance in childhood cancer rhabdomyosarcoma (RMS) cell lines with differential sensitivity to a novel topoisomerase II inhibitor, AS-DACA. The current study aims to explore the contribution of the endocytic pathway to AS-DACA sequestration in RMS cell lines. A 24-fold differential in AS-DACA cytotoxicity was detected between the RMS lines RD and Rh30. The effect of inhibitors of the endocytic pathway on AS-DACA sensitivity in RMS cell lines, coupled with the variations of endosomal marker expression, indicated the late endosomal/lysosomal compartment was implicated by confounding lines of evidence. Higher expression levels of Lysosomal-Associated Membrane Protein-1 (LAMP1) in the resistant RMS cell line, RD, provided correlations between the increased amount and activity of these compartments to AS-DACA resistance. The late endosomal inhibitor 3-methyladenine increased AS-DACA sensitivity

Rhabdomyosarcoma comprises two major subtypes, fusion positive (PAX3-FOXO1 or PAX7-FOXO1) and fusion negative. To investigate the significance of DNA methylation in these subtypes, we analyzed methylation profiles of 37 rhabdomyosarcoma tumors and 10 rhabdomyosarcoma cell lines, as well as 8 normal tissues. Unsupervised clustering of DNA methylation clearly distinguished the fusion-positive and fusion-negative subsets. The fusion-positive tumors showed substantially lower overall levels of methylation compared with fusion-negative tumors. Comparison with the methylation pattern of normal skeletal muscle and bone marrow indicates that fusion-negative rhabdomyosarcoma is more similar to these normal tissues compared with fusion-positive rhabdomyosarcoma, and suggests that many of the methylation differences between these subtypes arise from aberrant hyper- and hypomethylation events in fusion-positive rhabdomyosarcoma. Integrative methylation and gene expression analysis revealed that ...

This procedure is also called computed tomography, computerized tomography, or computerized axial tomography ...

Another remarkable property of the 8H9 antigen is its expression on tumors of diverse lineage, neuroectodermal and mesenchymal tumors, and to a lesser degree, epithelial tumors. No mAb to date has the binding spectrum described with 8H9. This broad distribution provides mAb 8H9 the potential of being a generic tumor antigen for targeted therapy. Of particular interest is its expression on 28 of 29 rhabdomyosarcoma tumors and the rhabdomyosarcoma cell lines tested by indirect immunofluorescence. Disseminated and high-risk rhabdomyosarcomas have a very poor prognosis with a ,40% long-term survival rate (27) . Although the MyoD family of oncofetal proteins is specific to rhabdomyosarcoma, oncofetal proteins are nuclear antigens and therefore unlikely candidates for antibody-based therapy (19) . In a preliminary report, cross-reactivity of the mAb BW575 raised against small cell lung carcinoma with rhabdomyosarcoma cell lines and 2 of 2 rhabdomyosarcoma sections was described. However, this antibody ...

N2 - Rhabdomyosarcoma (RMS) is a soft tissue sarcoma and is most frequently found in children. In RMS, there are two major subtypes, that is, embryonal RMS and alveolar RMS (ARMS). ARMS has exclusively the worse prognosis and is caused by formation of the chimeric PAX3-FOXO1 gene. Regarding cancer, the Warburg effect is known as a feature of cancer-specific metabolism. Polypyrimidine tract-binding protein 1 (PTBP1), a splicer of pyruvate kinase muscle (PKM) mRNA, is a positive regulator of cancer-specific energy metabolism. We investigated the expression and effects of muscle-specific miR-1 and miR-133b on RMS cells (RD, KYM-1, Rh30, and Rh41) from the view of ...

Rhabdomyosarcoma (RMS) is a highly malignant pediatric cancer that is the most common form of soft tissue tumors in children. RMS cells have many features of skeletal muscle cells, yet do not differentiate. Thus, our studies have focused on the defects present in these cells that block myogenesis. Protein and RNA analysis identified the loss of MEF2D in RMS cells. MEF2D was expressed in RD and RH30 cells by transient transfection and selection of stable cell lines, respectively, to demonstrate the rescue of muscle differentiation observed. A combination of techniques such as proliferation assays, scratch assays and soft agar assays were used with RH30 cells expressing MEF2D to demonstrate the loss of oncogenic growth in vitro and xenograft assays were used to confirm the loss of tumor growth in vivo. Here, we show that one member of the MEF2 family of proteins required for normal myogenesis, MEF2D, is largely absent in RMS cell lines representing both major subtypes of RMS as well as primary cells

Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in children. The name is derived from the Greek words rhabdo, which means rod shape, and myo, which means muscle.

The main purpose of this study is to see if using proton beam radiation therapy instead of photon beam radiation therapy can reduce side effects from radiation treatment for rhabdomyosarcoma. Photon beam radiation is the standard type of radiation for treating most rhabdomyosarcoma and many other types of cancer. Photon beam radiation enters the body and passes through healthy tissue, encounters the tumor, then leaves the body through healthy tissue. A beam of proton radiation enters the body and passes through healthy tissue, encounters tumor, but then stops. This means that less healthy tissue is affected by proton beam radiation than by photon beam radiation ...

Human rhabdomyosarcoma cells express membrane epidermal growth factor receptor (EGF-R), which could confer responsiveness to EGF and transforming growth factor-α (TGF-α) of autocrine or paracrine origin. To study the role played by this growth factor circuit in the proliferation and differentiation of myogenic noeplastic cells, human rhabdomyosarcoma EGF-R-expressing cells (RD/18 clone) have been transfected with a plasmid containing a fragment of the EGF-R cDNA in the antisense orientation. in vitro growth and differentiative ability were studied on six antisense-transfected clones (AS) in comparison to parental RD/18 cells and to cells transfected with the plasmid containing only the neomycin resistance gene (NEO). A reduced EGF-R membrane expression was found in AS clones by decreased immunofluorescence with an anti-EGF-R monoclonal antibody. All AS transfectants had a greatly impaired proliferative ability, even when cultured in fetal bovine serum-containing medium. Proliferation of AS ...

BACKGROUND Transforming growth factor beta (TGF-beta) plays an essential role in the regulation of normal physiologic processes of cells. TGF-beta has been shown to regulate several mitogen-activated protein kinases (MAPK) pathways in several epithelial cells. However, the effects of TGF-beta on soft tissue sarcoma are seldom reported. Our previous studies suggested that there should be some other signal transduction pathways besides Smads, which are important to regulate the growth of human embryonal rhabdomyosarcoma (RMS) cells. In the present study, we examined the expression and functional relations of extracellular signal-regulated kinase 2 (ERK2) and Smad4 in human RMS tissue and a RMS cell line, RD. METHODS RD cells and normal human primary skeletal myoblasts (Mb) were treated with TGF-beta1 to establish the expression profile of ERK2 at the mRNA and protein levels detected by RT-PCR and immunofluorescence. Immunohistochemistry was used to detect the expression of ERK2 and Smad4 in 50 tissue

Retroperitoneal lymph node dissection (RPLND) was used in 121 Intergroup Rhabdomyosarcoma Study (IRS) III patients with nonmetastatic paratesticular (PT) rhabdomyosarcoma (RMS) to assess retroperitoneal lymph node (RPLN) involvement so as to determine the need for x-ray therapy (XRT). Clinical node evaluation (CNE) was accomplished by a computed tomography (CT) scan in 105 and a sonogram in six. Pathological node evaluation (PNE) was performed in 113: lymphadenectomy (9 bilateral, 85 unilateral) and biopsy in 19. Vincristine and actinomycin D were used for 1 year postoperatively in 89%; all patients who had positive PNE received RPLN XRT. This study compares CNE with PNE and evaluates predictors of relapse and survival. Findings: There were clinically negative nodes (cN0) in 81% of the 121 patients. Among cN0 patients, 14% had positive nodes (pN1). Of the clinically positive (cN1) patients, 94% had pN1. RPLN relapse occurred in only two of the 121 patients. Initially both had cN0 and one had PNE ...

The disorder is a disease in which malignant cells begin growing in muscle tissue. Rhabdomyosarcoma is a type of a sarcoma, which means a cancer of the bone, soft tissues, or connective tissue (e. g. , tendon or cartilage). Rhabdomyosarcoma begins in the soft tissues in a type of muscle called striated muscle. It can occur anywhere in the body. Rhabdomyosarcoma accounts for more than half of all diagnosed sarcomas in children and is much more likely in males than in females. Rhabdomyosarcoma has many symptoms that depend upon where the sarcoma is located upon the body.. If your sarcoma is locates in the neck or head areas, then you would be visibly able to see a lump or a discoloration of the skin with possibly swelling in the neck and adams apple region. Malignant cells that are located in the nose and sinus area would be marked by a difference in the voice, heavy nosebleeds, headaches, difficulty breathing and disruption of the swallowing process. Prostate seated sarcomas would leave traces of ...

Adjusting to life after treatment for childhood rhabdomyosarcoma is different for each child. Learn how to cope with the late effects for rhabdomyosarcoma.

Rhabdomyosarcoma (RMS) is the most common malignant soft tissue tumor in children and is highly resistant to all forms of treatment currently available once metastasis or relapse has commenced. As it has recently been determined that the acetylcholine receptor (AChR) γ-subunit, which defines the fetal AChR (fAChR) isoform, is almost exclusively expressed in RMS post partum, we recombinantly fused a single chain variable fragment (scFv) derived from a fully human anti-fAChR Fab-fragment to Pseudomonas exotoxin A to generate an anti-fAChR immunotoxin (scFv35-ETA).While scFv35-ETA had no damaging effect on fAChR-negative control cell lines, it killed human embryonic and alveolar RMS cell lines in vitro and delayed RMS development in a murine transplantation model. These results indicate that scFv35-ETA may be a valuable new therapeutic tool as well as a relevant step towards the development of a fully human immunotoxin directed against RMS. Moreover, as approximately 20% of metastatic malignant melanomas

Rhabdomyosarcoma mimicking Wilms tumor.: A case of a 6 year old child, with a pleomorphic rhabdomyosarcoma involving simultaneously the leg muscles and the kid

Rhabdomyosarcoma is the most common soft tissue sarcoma in childhood. Its clinical, biological and pathological characteristics vary considerably. Rhabdomyosarcoma is almost exclusively a pediatric malignancy with two age peaks 2 - 6 years (usually head and neck and genitourinary tract sites) and 15 - 19 years (usually extremity, trunk, and paratesticular sites). Rhabdomyosarcoma derives from primitive mesenchymal cells which demonstrate muscle differentiation on histological, immunochemical or electron microscopic evaluation. There are four histological types in decreasing order of frequency: embryonal, alveolar, undifferentiated and botryoidal. The alveolar type tends to affect the extremities and have a poor prognosis. Rhabdomyosarcomas of the trunk present most often as a painless mass. Rhabdomyosarcoma most commonly spreads to regional lymph nodes and less commonly to the lung, bone and bone marrow. Rhabdomyosarcoma and other soft tissue sarcomas have been shown to be FDG avid and ...

AIMS: Subclassification of rhabdomyosarcoma (RMS) has clinical relevance, as the two major subclasses embryonal (ERMS) and alveolar (ARMS) rhabdomyosarcoma differ greatly in terms of aggressiveness and prognosis. However, histological analysis is not always sufficient for an unequivocal subclassification of RMS. Furthermore, clinical presentation of ARMS has been reported to mimic other tumour types, specifically lymphoma. The aim was to determine the role of four biomarkers in the diagnosis of rhabdomyosarcoma. METHODS AND RESULTS: Recently, we identified four potential biomarkers to subclassify RMS with high sensitivity and specificity. These included epidermal growth factor receptor (EGFR) and fibrillin-2 as markers for ERMS, and AP2beta and P-cadherin as markers for translocation-positive ARMS. Here, we further validate the potential of these four markers in a second, independent patient cohort by immunohistochemistry on 80 sections of RMS biopsy specimens as well as a tissue microarray ...

There is strong evidence supporting a critical role of IGF-IR in tumorigenesis, tumor survival, and metastasis in a wide variety of human cancers including pediatric tumors (3, 6). Our present study showed that SCH 717454, a fully human neutralizing monoclonal antibody specific for IGF-IR, inhibits tumor growth as a single agent. In addition, its combination with conventional chemotherapeutic agents (cyclophosphamide and cisplatin) results in a greater antitumor effect than that observed for either single agent alone in neuroblastoma, osteosarcoma, and rhabdomyosarcoma tumor xenograft models. SCH 717454 inhibits rhabdomyosarcoma xenograft growth only partially while inhibiting the growth of neuroblastoma and osteosarcoma tumors almost completely. This finding is consistent with the reported existence in rhabdomyosarcoma cells of redundant growth factor autocrine loops (14) and suggests that the IGF/IGF-IR loop represents a dominant mechanism in the growth of neuroblastoma and osteosarcoma ...

Recently several studies have described the in vivo gene expression profiles of rhabdomyosarcoma, with the aim of associating specific genes that distinguish subtypes of rhabdomyosarcoma either for tumor diagnosis or for tumorigenesis (4, 6, 12-18, 30). Our study represents the first attempt to identify novel therapeutic targets by directly measuring the inhibitory effect of siRNA libraries on the growth of rhabdomyosarcoma cells. As a result, we have identified 16 phosphatases and 50 kinases that play significant roles in the growth control of rhabdomyosarcoma cells. Some of these genes are implicated in rhabdomyosarcoma cells for the first time, whereas others have previously been linked to this disease, including CDK4, PDGFRA, PRKCD, PRKCQ, SKP2, etc. (Table 2; refs. 4, 22, 25, 31). Overall these examples illustrate the power of using an unbiased genome-wide screening strategy to identify novel targets, particularly when the results confirm more traditional candidate gene approaches. The ...

In order to better understand cellular responses to viral infection at the transcriptional level, we employed differential display RT-PCR to analyze mRNAs from RD rhabdomyosarcoma cells following infection with a neurovirulent enterovirus 71 (EV71) strain, compared with mRNAs from uninfected cells. Of 250 expressed sequence tags (ESTs) isolated, sequenced, and identified, all were of cellular origin except 1 that was of viral origin. Of these, 156 were individual distinctive clones, comprising 45 mRNAs showing unaltered expression and 111 mRNAs exhibiting upregulation or downregulation. Of the 45 uniformly expressed mRNAs, 14 represented unknown genes. Of the 111 differentially expressed mRNAs, 63 did not match any known genes. Forty-eight of the 111 mRNAs modified by EV71 infection matched known genes, including those encoding components of cell cycle, cytoskeleton, and cell death mediators; protein degradation mediators; mitochondrial-related proteins; components of protein translation and ...

To evaluate the performance of three different advanced treatment techniques on a group of complex paediatric cancer cases. CT images and volumes of interest of five patients were used to design plans for Helical Tomotherapy (HT), RapidArc (RA) and Intensity Modulated Proton therapy (IMP). The tumour types were: extraosseous, intrathoracic Ewing Sarcoma; mediastinal Rhabdomyosarcoma; metastastis of base of skull with bone, para-nasal and left eye infiltration from Nephroblastoma of right kidney; metastatic Rhabdomyosarcoma of the anus; Wilms tumour of the left kidney with multiple liver metastases. Cases were selected for their complexity regardless the treatment intent and stage. Prescribed doses ranged from 18 to 53.2 Gy, with four cases planned using a Simultaneous Integrated Boost strategy. Results were analysed in terms of dose distributions and dose volume histograms. For all patients, IMP plans lead to superior sparing of organs at risk and normal healthy tissue, where in particular the integral

The over-all tabulation of all primary tumors, benign and malignant, contains about 500 cases, of which about 50% are myxomas.1 In 1945 Straus and Merliss2 quoted statistics indicating a frequency of primary heart tumors of only 0.001% in 480,331 autopsies. In 1931 Yater3 compiled 46 primary sarcomas of the heart. During the next 10 years Weir and Jones4 found 29 additional cases. In 1945 Mahaim5 published his extensive monograph and included 87 cases to that date. By 1949 Whorton6 was able to increase the number of primary sarcomas to 100, and in ...

N2 - Rhabdomyosarcoma (RMS) is the most common type of soft tissue sarcoma in children. Circulating tumor cells in peripheral blood or disseminated to bone marrow, a concept commonly referred to as minimal residual disease (MRD), are thought to be key to the prediction of metastasis and treatment efficacy. To date, two MRD markers, MYOD and MYOGENIN, have been tested; however, MRD detection continues to be challenging mainly owing to the closeness of the detection limit and the discordance of both markers in some samples. Therefore, the addition of a third marker could be useful for more accurate MRD assessment. The PAX3 gene is expressed during embryo ...

Embryonal rhabdomyosarcoma (ERMS) is a rare histological form of cancer of connective tissue wherein the mesenchymally-derived malignant cells resemble the primitive developing skeletal muscle of the embryo. It is the most common soft tissue sarcoma occurring in children. ERMS is the more common of two major subtypes of rhabdomyosarcoma, the other being alveolar rhabdomyosarcoma. It has been informally classified as a small round blue cell tumor because of the characteristic microscopic appearance of its cells after histological staining with hematoxylin and eosin. The prognosis for rhabdomyosarcoma has improved greatly in recent decades, with over 70% of patients surviving for five years after diagnosis.

A human tumor cell line designated RMS-GR was established from an embryonal rhabdomyosarcoma. The monolayer cells were polygonal, round or spindle-shaped. The RMS-GR cell line became stable with a doubling time of 42 h. Tumorigenicity of the cells was confirmed by hetero-transplantion into nude mice. Electron microscopic images showed typical cytoplasmic inclusion of aggregated intermediate filaments and myofibril-like thin filaments. The expression of desmin, vimentin, actin and human myoglobin was recognized by cytofluorometric analyses, and a large fraction of CK-MM and small fractions of CK-BB and MCK-1 isoenzymes were found. Chromosomal analysis showed that the modal chromosome number was consistently near triploid with structural abnormalities mostly involving chromosomes 1, 3 and 8, and additional unidentified markers. No alteration of chromosome 2 was observed. The RMS-GR cell line may provide a system to identify genes which are involved in the pathogenic mechanism of rhabdomyosarcomas, ...

The orbital rhabdomyosarcoma is one of the most frequent malignant orbital tumours in children. At this age, the common histological types are the embryonal and alveolar type. The onset is mainly under the age of 16. Without a recent and correct treatment it can give metastasis in lung and bone. The hereby paper presents one clinical case of a teenager presented at the ophthalmological consultation for a small tumor located in the superomedial part of the orbit. Computed tomography (CT) and magnetic resonance imaging (MRI) supported the diagnosis revealing the location and extension of the tumor. During the surgery, we discovered two small tumors and the histological examination revealed an embryonal type of orbital rhabdomyosarcoma. After the surgery, the patient followed an oncological treatment consisting of chemotherapy and local radiotherapy. The prognosis for life was favorable, linked with the recent diagnosis and treatment, the histological type and the good response at the oncological ...

Introduction: Rhabdomyosarcoma is an uncommon tumor seen in young adolescents and adults that metastasizes to the peritoneum. Case Report: Here we report a case of 18-year-old female who had alveolar rhabdomyosarcoma of nose and was treated with chemoradiotherapy. After one year, she presented with ascites. Ascitic fluid cytology revealed deposits of rhabdomyosarcoma. Immunohistochemistry done to support the diagnosis. This case report highlights the cytological features of rhabdomyosarcoma cells, which were large pleomorphic with high nuclear cytoplasmic ratio, coarse chromatin and scant cytoplasm. A small population of cells was almost the size of mesothelial cells, which could be mistaken for a reactive mesothelial cells. Conclusion: Awareness of rare metastases of rhabdomyosarcoma in peritoneum and recognition of the cytological features of these malignant cells supported by specific immunostains helps in the diagnosis.

Initial magnetic resonance images showed signs of low-grade glioma in the frontal lobe. Stereotactic biopsy was performed, and a diagnosis of diffuse astrocytoma was confirmed. Three months later, the patient presented with a high-grade tumor as seen on imaging studies. He underwent total resection of the tumor and histopathological tests identified an undifferentiated sarcoma. The patient died eight months later due to massive tumor bleeding. To the best of our knowledge, this is the first report of undifferentiated sarcoma arising from ...

It is believed that some rhabdomyosarcoma tumors begin developing in the fetus. Rhabdomyoblasts are the cells at the initial stages of development of an unborn baby. These cells will mature and develop into muscles. There has been much research into the gene structure of these rhabdomyoblasts and possible detection of a gene error that can produce the disease later in development.. Rhabdomyosarcomas usually have some type of chromosome abnormality in the cells of the tumor, which are responsible for the tumor formation. In children with an embryonal rhabdomyosarcoma, there is usually an abnormality of chromosome 11. In alveolar rhabdomyosarcoma, a rearrangement in the chromosome material between chromosomes 2 and 13 is usually present. This rearrangement changes the position and function of genes, causing a fusion of genes referred to as a fusion transcript. Patients have an abnormal fusion transcript involving two genes known as PAX3 and FKHR. This important discovery has led to improvements in ...

The exfoliative cytology of rhabdomyosarcomas in body fluids has not been described in detail. However, FNA studies have shown that the cytomorphology of rhabdomyosarcomas is characterized by the presence of a dual cell population; the first cell type is small, non-descript, with scant cytoplasm, hyperchromatic nuclei, and inconspicuous nucleoli, and resembles large lymphocytes, and a more differentiated second population is of rhabdomyoblasts with distinctive cytological features. These include strap-cells with cross-striations, reflecting myotubule differentiation, tadpole or ribbon-shaped cells with abundant, deeply eosinophilic cytoplasm.[9] Alveolar rhabdomyosarcomas and embryonal rhabdomyosarcomas differ in the relative proportion of more differentiated, distinctive rhabdomyoblastic cells. Such cells are common in embryonal rhabdomyosarcomas and may be completely absent in ARM. ARM has been reported to show more frequent binucleated or giant multinucleated cells, alveolar structures, ...

Often times when I lay out what I know to people its as if they go into brain lock because it does not fit in what they are told by the medical establishment which is controlled & manipulated by the drug companies who profit from long term sickness & drug sales so never getting at the cause and the inexpensive cure does not support that industry.. Most people dont know how to properly use keywords to get to the truth. I want to show you something. Due to my studies pertaining to vaccines and Corporate lies I have learned to always use the keyword vaccines in my searches so my first google search was vaccine induced Undifferentiated Sarcoma. That was very interesting to find articles on Undifferentiated Sarcoma in cats caused by vaccines and that it can occur within days or up to 10yrs from the vaccine. Keep doing research along this line. If your son had any vaccines within the past 10 years there definitely could be a link but if you ask an MD he will automatically deny any relation to ...

Since publication of the classic descriptions by Riopelle and ThÉRiault (1956) and Enzinger and Shiraki (1969) the morphology of alveolar rhabdomyosarcoma (aRMS) has been well known. RMS presenting with clear and unequivocal (pseudo)alveolar spaces can be recognized at first sight as the alveolar (sub-)type of RMS. On the other hand, a diagnosis of aRMS may be difficult in cases which display neither significant evidence of rhabdomyogenesis in conventionally stained slides nor unambiguous alveolar spaces. In such cases the diagnosis of RMS must be confirmed by special staining including immunohistochemistry. ...

The cause of rhabdomyosarcoma is unknown. How should it be treated? It affects soft, connective tissue, and can hit many systems of the body.

Alveolar rhabdomyosarcoma (ARMS) is an aggressive paediatric cancer of skeletal muscle with poor prognosis. A PAX3-FOXO1 fusion protein acts as a driver of malignancy in ARMS by disrupting tightly coupled but mutually exclusive pathways of proliferation and differentiation. While PAX3-FOXO1 is an attractive therapeutic target, no current treatments are designed to block its oncogenic activity. The present work shows that the histone acetyltransferase P/CAF (KAT2B) is overexpressed in primary tumours from ARMS patients. Interestingly, in fusion-positive ARMS cell lines, P/CAF acetylates and stabilizes PAX3-FOXO1 rather than MyoD, a master regulator of muscle differentiation. Silencing P/CAF, or pharmacological inhibition of its acetyltransferase activity, down-regulates PAX3-FOXO1 levels concomitant with reduced proliferation and tumour burden in xenograft mouse models. Our studies identify a P/CAF-PAX3-FOXO1 signalling node that promotes oncogenesis and may contribute to MyoD dysfunction in ...

Suppression of the hosts immune system plays a major role in cancer progression. Tumor signaling of programmed death 1 (PD1) on T cells and expansion of myeloid-derived suppressor cells (MDSCs) are major mechanisms of tumor immune escape. We sought to target these pathways in rhabdomyosarcoma (RMS), the most common soft tissue sarcoma of childhood. Murine RMS showed high surface expression of PD-L1, and anti-PD1 prevented tumor growth if initiated early after tumor inoculation; however, delayed anti-PD1 had limited benefit. RMS induced robust expansion of CXCR2+CD11b+Ly6Ghi MDSCs, and CXCR2 deficiency prevented CD11b+Ly6Ghi MDSC trafficking to the tumor. When tumor trafficking of MDSCs was inhibited by CXCR2 deficiency, or after anti-CXCR2 monoclonal antibody therapy, delayed anti-PD1 treatment induced significant antitumor effects. Thus, CXCR2+CD11b+Ly6Ghi MDSCs mediate local immunosuppression, which limits the efficacy of checkpoint blockade in murine RMS. Human pediatric sarcomas also ...

Rhabdomyosarcoma is a primitive neoplasm with a poorly understood etiology that exhibits features of fetal skeletal muscle. of both and PA-824 through promoter and manifestation analyses suggested that increased resistance to apoptosis was associated with the inhibition of the Wnt signaling pathway. These results suggest that altered AP-1 activity that leads to PA-824 the down-regulation of the Wnt pathway may contribute to the inhibition of myogenic differentiation and resistance to apoptosis in ERMS cases. Efforts to unravel the molecular events underlying the origin of different types of cancer have contributed to obtaining treatments for these diseases. However, largely left behind in this effort are tumors with poorly comprehended etiologies like rhabdomyosarcoma (RMS). RMS explains a heterogeneous group of poorly differentiated pediatric sarcomas that display features of developing muscle.1 Representing 60% PA-824 of all pediatric sarcomas and accounting for 5% to 10% of all childhood ...

July 9, 2012 -- There may be some association between dental x-rays and certain types of cancer, according to a review by the Canadian Agency for Drugs and Technologies in Health (CADTH; Journal of the Canadian Dental Association, 2012; 78:c79).. Based on data from eight case-control studies that assessed the association between exposure frequency to dental x-rays and brain tumors (five reports), thyroid cancer (one report), breast cancer (one report), or pediatric cancer of connective tissues (one report), the CADTH review presents some evidence that dental x-rays may increase the risk for cancer, the agency noted.. There is some evidence of an association between exposure to dental x-rays and meningioma, and thyroid cancer or breast cancer, when shielding with a lead apron is not used, the CADTH wrote. An association between pediatric rhabdomyosarcoma and maternal exposure to x-rays was also detected. No association between gliomas or acoustic neuromas and dental x-rays were ...
