Summary
Brief summary
The purpose of this study is to determine which of the most commonly used chemotherapy used in recurrent and primary refractory Ewing sarcoma is most beneficial.

Who is it for?
You may be eligible for this study if you are aged 2 years or above and have been diagnosed with relapsed or refractory Ewing sarcoma.

Study details:
Participants in this trial will be randomly allocated to one of the available treatment groups. These groups include Topotecan and Cyclophosphamide (TC), Carbonplatin and Etoposide (CE) and high dose Ifosfamide (IFOS).
Before treatment starts the following routine tests will be performed:
Physical check-up including measuring height and weight
Blood tests +/- urine tests
Assessment of kidney function called a GFR.
Scans (which may include CT, PET-CT, MRI, bone scan, x-ray). The doctor will decide which type of scans needed depending on where the tumour is located.
A quality of life questionnaire will also be completed before treatment commences.

During trial treatment
While you are having chemotherapy treatment you will be carefully monitored using the same routine tests that would be used if you were having chemotherapy but were not in the trial. These routine tests will include blood +/- urine tests, scans and GFR. These tests are to ensure that you are fit to continue chemotherapy. In addition if you have had a PET-CT scan before treatment, you will have another PET-CT scan after 4 cycles of chemotherapy.
You will be asked to complete two more quality of life questionnaires, one on completion of cycle 2 and one on completion of cycle 4.

All treatments in this study are those which are currently used routinely for treatment of Ewing sarcoma.

It is hoped that this research will help to determine which of the treatments is most effective in improving overall survival, side effects, tumour shrinkage, quality of life and days spent in hospital.
