About this trial
This study compares carbon ion therapy, surgery, and proton therapy to determine if one has better disease control and fewer side effects. There are three types of radiation treatment used for pelvic bone sarcomas: surgery with or without photon/proton therapy, proton therapy alone, and carbon ion therapy alone. The purpose of this study is to compare quality of life among patients treated for pelvic bone sarcomas across the world, and to determine if carbon ion therapy improves quality of life compared to surgery and disease control compared with proton therapy.
Eligibility criteria
Qualifiers
Males and females >= 15 years of age
Newly diagnosed, histologic confirmation of pelvic chordoma, chondrosarcoma, osteosarcoma, Ewing sarcoma with bone involvement, rhabdomyosarcoma (RMS) with bone involvement or non-RMS soft tissue sarcoma with bone involvement
No evidence of distant sarcoma metastases as determined by clinical examination and any form of imaging
Eastern Cooperative Oncology Group (ECOG) performance status (PS) =< 2
Disqualifiers
Patients receiving palliative treatment
Recurrent disease
Males and females < 15 years of age
Previous radiation therapy to the site of the sarcoma or area surrounding it such that it would be partially or completely encompassed by the radiation volume needed to treat the current sarcoma. In other words, treatment on this study would require re-irradiation of tissues
