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...

UNLABELLED Rhabdomyosarcoma is the most common form of soft tissue sarcoma in young children. In soft tissue sarcomas, isolated metastases are seen in the lung, soft tissue, and bone. The optimal management of these tumors depends on the site, size, and grade of the local growth, and accurate staging of the disease when first seen. Although detection of the primary site of disease is usually ac...

AIMS To assess the impact of treatment for embryonal rhabdomyosarcoma on spinal growth and limb length and examine the response of these parameters to growth hormone (GH) treatment. METHODS We conducted a retrospective case note review of 17 survivors of head and neck rhabdomyosarcoma followed up at a single institution. All children had been treated with chemotherapy and local radiotherapy. ...

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...

Rhabdomyosarcoma is the most commonly occurring soft-tissue sarcoma in childhood. Most rhabdomyosarcoma falls into one of two biologically distinct subgroups represented by alveolar or embryonal histology. The alveolar subtype harbors a translocation-mediated PAX3:FOXO1A fusion gene and has an extremely poor prognosis. However, tumor cells have heterogeneous expression for the fusion gene. Usin...

Paratesticular embryonal rhabdomyosarcoma (RMS) is a rare tumor arising from the mesenchymal tissues of the spermatic cord, epididymis, testis and testicular tunics. We report three cases of adult paratesticular RMS, two embryonic and one pleomorphic rhabdomyosarcoma. All the patients underwent diagnostic orchidectomy. The work up investigations revealed lung metastases. Chemotherapy with Ifosf...

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)...

We report the case of a 29 year-old male who presented with hemospermia. A biopsy revealed an embryonal rhabdomyosarcoma of the prostate and the patient was treated with pre-operative chemotherapy according to the pediatric protocol IVAD (Ifosfamide Actinomycin Doxorubicin – Vincristine) followed by prostatectomy. Pathologic examination of the prostate showed the persistence of an immature tera...

Introduction: Primary embryonal rhabdomyosarcoma of prostate (ERMP) is an extremely rare pathological and clinical entity in adults. It’s characterized by extensive loco-regional spread and a tendency to metastasize by blood stream and regional lymphatics. In adult patients, data available on the management of ERMP are limited and mostly derived from the pediatric clinical trials on rhabdomyosa...
