Clinical Trial: Post-operative Radiotherapy in Poor Responders Ewing's Sarcoma Patients
Study Status: Withdrawn
Recruit Status: Withdrawn
Study Type: Interventional
Official Title: Post-operative Radiotherapy Randomization in Poor Responders Ewing's Sarcoma Patients
Brief Summary:
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.
