Myoblast cell cycle exit and differentiation are mediated in part by down-regulation of cyclin D1 and associated cyclin-dependent kinase (Cdk) activity. Because rhabdomyosarcoma may represent a malignant tumor composed of myoblast-like cells failing to exit the cell cycle and differentiate, we considered whether excess Cdk activity might contribute to this biology. Cyclin D-dependent Cdk4 and C...
Treatment of childhood rhabdomyosarcoma is limited by recurrent disease and the development of multidrug resistance. Therefore, novel treatment options are desirable. Photodynamic therapy (PDT) using the photodynamic agent hypericin is proposed as an alternative approach for intraoperative visualization and treatment of this disease. The aim of this study was to investigate in vitro effects of ...
Rhabdomyosarcoma is the most common soft tissue sarcoma affecting children, and the overall cure rate of children with metastatic disease remains below 30%. The CXC chemokine receptor-4 (CXCR4)/stromal cell-derived factor-1 (SDF1) axis has been implicated in the promotion of metastatic potential in several tumors. In this study, we developed a novel anti-CXCR4 mAb, CF172, and investigated its a...
Uterine rhabdomyosarcoma is rare, with only 60 reported cases. We describe an asymptomatic patient with metastatic uterine rhabdomyosarcoma manifested as extensive mediastinal lymphadenopathy. This 73-year-old woman had been previously treated for endometrial rhabdomyosarcoma and was referred to us when a right hilar density was seen on a chest radiograph; computed tomography showed a nodule in...
CONTEXT Alveolar rhabdomyosarcoma are rare malignancies. These lesions typically metastasize to the lungs, liver, and bone marrow. Pancreatic metastases from alveolar rhabdomyosarcoma are exceptionally uncommon. CASE REPORT An 18-year-old man with a history of right orbital alveolar rhabdomyosarcoma, which had been treated with neoadjuvant therapy, surgery and adjuvant chemotherapy developed ...
Interleukins-6 (IL-6)/GP130 signaling pathway represents a promising target for cancer therapy due to its critical role in survival and progression of multiple types of cancer. We have identified Bazedoxifene, a Food and Drug Administration (FDA)-approved drug used for the prevention of postmenopausal osteoporosis, with novel function as inhibitor of IL-6/GP130 interaction. In this study, we in...
UNLABELLED Rhabdomyosarcoma is the most common soft tissue sarcoma in children. Metastatic rhabdomyosarcoma in children has a 5-year event-free survival rate of <30%, and a recent clinical trial with irinotecan, a topoisomerase I inhibitor, failed to improve outcome. Therefore, it was surmised that failure of irinotecan may be the result of overexpression of the DNA repair enzyme tyrosyl-DNA ph...
Rhabdomyosarcoma is a malignant neoplasm of primitive mesenchyme exhibiting skeletal muscle differentiation. Rhabdomyosarcoma, which can histopathologically be of embryonal, alveolar, botryoid and pleomorphic types; is a rare tumor in children, with an annual incidence of 4.3 cases per million. Pleomorphic rhabdomyosarcomas is a rare variant, occurring more commonly in adults. We report a rare ...
BACKGROUND Embryonal rhabdomyosarcoma of the prostate in an adult is a very rare event with only a few cases published. Diagnosis usually occurs with advanced disease frequently already with metastatic spread. In adults prognosis is very poor, therefore early diagnosis is crucial. To date, only three cases of spindle cell subtype of embryonal rhabdomyosarcoma of the prostate in an adult have be...
Rhabdomyosarcoma is the most common soft tissue sarcoma in infants and children. The peak incidence of rhabdomyosarcoma occurs in children between 2 and 5 years of age, and a second peak is seen in teenagers between 15 and 19 years of age. In the final report of 686 patients from the First Intergroup Rhabdomyosarcoma Study (IRS), the median age at diagnosis for a child presenting with rhabdomyo...
