From a chemotherapy standpoint, all stages of Ewing Sarcomas are approached the same way. There are differences in surgical approach between localized disease versus metastatic disease. We give VAC alternating with IE for six cycles, each. Since this is resected, this regimen should be given in the ...

The general consensus would be to treat with SOC systemic therapy. This typically is the alternative VAC/IE regimen (or VAI for some) with the caveat that renal function needs to be acceptable, especially if the patient has already had a nephrectomy. The duration answer may differ a bit between pedi...

The COG AEWS1031 protocol allowed the use of C/E - cyclophosphamide/et...
