简要总结

Background :

Recurrent/relapsed Ewing’s sarcoma has a poor outcome, especially patients with systemic relapse. Multiple regimens are used at progression, but none have been established as the standard of care. According to a recent ongoing, randomised trial, High dose ifosfamide was found to perform better in terms of a better survival, albeit with higher toxicity rates and treatment discontinuation. The intent of the treatment in a recurrent setting is palliative, and should take into account the side effects. Ifosfamide-etoposide rechallenge, after a treatment free interval is an option, which may be safe and effective, and improve the quality of life of these patients. IE is an established part of treatment in the first line setting, especially for non-metastatic ewing’s, however, there is no data regarding its use in the second line setting, especially in patients who have received VAC/IE in the first line setting. The current study will be done to assess the efficacy and safety of this combination in the indian population.

Methodology

The total sample size will be 42. Patients after an informed consent, Age of 5 to 50 years with Histologically proven Ewing’s sarcoma at initial diagnosis or recurrence with Distant, combined (local plus distant) relapse or isolated local recurrence which is unresectable upfront and with a Treatment free interval with Ifosfamide and etoposide more than 12 months , progressing after one or more lines of chemotherapy with ECOG PS 0-2, and acceptable lab parameters as defined in the inclusion and exclusion criteria will be recruited. They will receive Ifosfamide etoposide every 21 days, with dose modification based on severity of toxicities, according to the mentioned criteria.

Outcomes

Primary endpoint is the Objective Response rate, which will be based on response assessment with repeat Imaging, defined according to the RECIST criteria. Secondary outcomes to be evaluated, include, Duration of Response, Progression Free Rate at 3 months, quality of life and Side effect Profile. Patients with response to the chemotherapy will be given a total of 6 cycles.
