Summary
The purpose of this study is to determine which of the most common chemotherapies used to treat recurrent or primary refractory Ewing Sarcoma is most beneficial.
Who is it for?
People may be eligible for this study if they 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 (by chance) to one of the available treatment groups.
Before treatment starts, the following routine tests will be performed:
- Physical check-up, including measuring height and weight
- Blood tests, and possibly 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 are needed depending on where the tumour is located.
- A quality of life questionnaire will also be completed before treatment commences.
During trial treatment
While participants are having chemotherapy treatment, they will be carefully monitored using the same routine tests that would be used if they were having chemotherapy but were not in the trial. These routine tests will include blood and urine tests, scans and GFR. These tests are to ensure people are fit to continue chemotherapy. In addition, if someone has had a PET-CT scan before treatment, they will have another PET-CT scan after 4 cycles of chemotherapy.
Participants 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.
