Adult rhabdomyosarcoma (RMS) in the urinary bladder is rare, and is the subject of case reports and small series. It consists of sheets of small round blue cells with high nuclear cytoplasmic ratio, brisk mitosis and apoptosis. In this study, we reported one case of pure rhabdomyosarcoma and two cases of urothelial carcinomas with extensive rhabdomyosarcomatous differentiation. In addition, the...
Multimodal treatment has improved the outcome of many solid tumors, and in some cases the use of radiosensitizers has significantly contributed to this gain. Activation of the extracellular signaling kinase pathway (MEK/ERK) generally results in stimulation of cell growth and confers a survival advantage playing themajor role in human cancer. The potential involvement of this pathway in cellula...
BACKGROUND The aim of the study is to investigate the clinical features, treatments, and prognosis of stage 1 embryonal rhabdomyosarcoma of the female genital tract. METHODS A retrospective analysis was performed on nine cases of stage 1 embryonal rhabdomyosarcoma of the female genital tract. Clinical characteristics, treatments, recurrence, and prognosis were analyzed. RESULTS Of the nine ...
Carcinoembryonic antigen (CEA) is a highly glycosylated cell surface glycoprotein belonging to the immunoglobulin superfamily. CEA has been involved in vitro in adhesion mechanisms, but little is known about the function of this glycoprotein in vivo in normal tissue differentiation and malignancy. With regard to the relationship between CEA expression and tissue differentiation, it has been rep...
The Hippo effector YAP has recently been identified as a potent driver of embryonal rhabdomyosarcoma (ERMS). Most reports suggest that the YAP paralogue TAZ (gene symbol WWTR1) functions as YAP but, in skeletal muscle, TAZ has been reported to promote myogenic differentiation, whereas YAP inhibits it. Here, we investigated whether TAZ is also a rhabdomyosarcoma oncogene or whether TAZ acts as a...
Sphingolipids is the collective term ascribed to components of the sphingomyelin cycle. Modulation of the cellular levels of individual sphingolipids can induce a diverse range of cellular responses including apoptosis, proliferation, and cell cycle arrest. We present data showing that rhabdomyosarcoma cell lines, independent of lineage (alveolar rhabdomyosarcoma and embryonal rhabdomyosarcoma)...
Rhabdomyosarcoma is the most common soft tissue sarcoma of childhood and adolescence. Despite advances in therapy, patients with a histologic variant of rhabdomyosarcoma known as alveolar rhabdomyosarcoma (ARMS) have a 5-year survival of <30%. ARMS is characterized by a chromosomal translocation generating the PAX3-FKHR fusion gene. However, ectopic expression of PAX3-FKHR often induces inhibit...
Background: Rhabdomyosarcoma (RMS) is one of the common malignant tumors in infants and children, but it is extremely rare in the kidney. In this paper, we present a case of RMS the kidney of a child. Case presentation: A 6-month old girl presented with agitation, low fever and abdominal distention which started 5 days ago. On physical examination, the infant had a large and firm soft tissue ma...
Pediatric sarcomas are rare malignancies accounting for about 10% of solid tumors in childhood. Sarcomas represent a heterogeneous group malignancies, especially they include Rhabdomyosarcoma (RMS) and Non-Rhabdomyosarcoma Type (STSNR). Therapeutic management pediatric is challenging. Multidisciplinary approach including chemotherapy, surgery radiotherapy the treatment choice. The correct affec...
