Study in Localized and Disseminated Ewing Sarcoma

Plain-language summary

Ewing Sarcoma Primary objectives: Standard Risk R1: in a randomised trial, to examine whether add-on treatment with zoledronic acid in addition to induction and maintenance chemotherapy improves event-free survival in patients with localised Ewing sarcoma and good histological response or with initial tumour volume \<200 mL compared to no add-on treatment. \*High Risk R2: in a randomised trial, to examine whether high-dose chemotherapy using busulfan-melphalan with autologous stem cell reinfusion, compared with standard chemotherapy, improves event-free survival in patients with localised Ewing sarcoma and poor histological response or tumour volume ≥200 mL (R2loc). In patients with pulmonary metastases high dose busulfan-melphalan chemotherapy with autologous stem cell reinfusion is randomised versus standard chemotherapy plus whole lung irradiation (R2pulm). Very High Risk R3: in a randomised trial, to examine whether the addition of high dose chemotherapy using treosulfan-melphalan followed by autologous stem cell reinfusion to eight cycles of standard adjuvant chemotherapy, compared to eight cycles of standard adjuvant chemotherapy alone, improves event-free survival in patients with primary disseminated disease. \*R2 accrual discontinued on December 1st 2015.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Diagnosis: Histologically confirmed Ewing sarcoma of bone or soft tissue. * Age and sex: Either sex, age \>48 months (for GPOH patients) and \<50 years at the date of diagnostic biopsy. Younger or elderly patients may be reported to the appropriate office (see section 1.4) but are not included in this study. * Registration: ≤ 45 days after diagnostic biopsy/surgery. * Start of chemotherapy: ≤ 45 days after diagnostic biopsy/surgery. * Informed consent: Must be signed prior to study entry. * Performance status: Lansky or Karnofsky score \> 50%, may be modified for handicapped patients. * Haematological parameters: * Haemoglobin \> 8 g/dl (transfusion allowed), * Platelets \> 80.000/µl (transfusion allowed), * WBC \> 2000/µl. * Cardiac values: LVEF \> 40%, SF \> 28%. Exclusion Criteria: * More than one cycle of other chemotherapy prior to registration * Second malignancy * Pregnancy and lactation * Concurrent treatment within any other clinical trial, except trials with different endpoints that due to the nature of their endpoints must run parallel to EWING 2008 e.g. trials on antiemetics, antimycotics, antibiotics, strategies for psychosocial support, etc... * Any other medical, psychiatric, or social condition incompatible with protocol treatment

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
