OBJECTIVE
To determine the efficacy of Arsenic trioxide combined with other chemo agents in patients with metastatic osteosarcoma and Ewing sarcoma.
METHODS
From December 2002 to June 2005, 32 patients with metastatic osteosarcoma and Ewing sarcoma were treated with chemotherapy comprised Arsenic
Ewing's sarcoma is the second most frequent primary malignant bone tumor, mainly affecting children and young adults. The notorious metastatic capability of this tumor aggravates patient mortality and remains a problem to be overcome. We investigated the effect of arsenic trioxide (As₂O₃) on the
Ewing sarcoma (ES), a highly malignant pediatric tumor, is consistently associated with translocations that fuse the EWS gene with a member of the ETS family gene, most commonly FLI-1. Despite significant advances with multiagent chemotherapy, surgery and radiotherapy, about 40% of ES patients still
Ewing sarcomas (ES) are rare mesenchymal tumours, most commonly diagnosed in children and adolescents. Arsenic trioxide (ATO) has been shown to efficiently and selectively target leukaemic blasts as well as solid tumour cells. Since multidrug resistance often occurs in recurrent and metastatic ES,
Arsenic and arsenious acids, cacodylic acid, atoxyl, and neosalvarsan fail to influence markedly the growth of the Rous chicken sarcoma.
Arsenic trioxide was tested against the PPTP in vitro panel (1.0 nM to 10 µM) and against the PPTP Ewing sarcoma in vivo panel administered intraperitoneally at a dose of 2.5 mg/kg daily × 5 per week for a planned treatment duration of 3 weeks. Arsenic trioxide showed a median relative IC(50) value
Arsenic trioxide (As(2)O(3)) induces both the differentiation and apoptosis of acute promyelocytic leukemia cells in a concentration dependent manner. We assessed the effects of As(2)O(3) in CADO-ES Ewing's sarcoma (ES), JK-GMS peripheral primitive neuroectodermal tumor (PNET), and SH-SY5Y
Ewing sarcomas (ES) are highly malignant mesenchymal tumors, which most often occur in children and adolescents. The current treatment of choice comprises wide resection in combination with multimodal chemotherapy including etoposide (Eto). Due to the serious side effects associated with common
Sarcoma is a rare form of cancer that differs from the much more common carcinomas because it occurs in a distinct type of tissue. Many patients of sarcoma have poor response to chemotherapy and an increased risk for local recurrence. Arsenic trioxide (ATO) is used to treat certain types of
BACKGROUND
Acute promyelocytic leukemia (APL) is a curable subtype of acute myeloid leukemia. APL is currently treated with combination of all-trans retinoic acid (ATRA) and arsenic trioxide (ATO) resulting in the induction of apoptosis and differentiation of the leukemic cells. Differentiation
