  Purpose

Local recurrence after surgical resection is a complex phenomenon. An important predictive factor is the response to chemotherapy. Central site of disease may be a second independent predictive factor (Lin et al. 2007). Patients with more than 10% viable tumour cells at surgery following neo-adjuvant chemotherapy had a less favourable outcome with an Event-free Survival [EFS] of 47% after 10 years. Patients with good histological response (< 10% viable tumour cells) after chemotherapy alone had a prognosis of about 70% after 10 years.

However, further studies are necessary to determine the merit of adjuvant radiation for high-risk patients (poor responders). Taking into consideration that the toxicity and morbidity of combined surgery and radiation is greater than either alone and must be closely monitored.

Primary Outcome Measures:
  • improved Local Relapse-free Survival (LRFS) [ Time Frame: five year event free survival ] [ Designated as safety issue: No ]
    Determine whether the administration of post-operative radiotherapy for poor responder Ewing Sarcoma patients to neo-adjuvant chemotherapy and radical surgery, leads to improved Local Relapse-free Survival (LRFS).
