Could more chemo stop sarcoma spread? new trial aims to find out

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria : 1. Histologically confirmed soft-tissue sarcoma by the RRePS (Réseau de Référence en Pathologie des Sarcomes et des Viscères) network, as recommended by the French NCI, 2. Grade 2 or 3 according to the FNCLCC grading system, 3. Available archived tumour sample for research purpose, 4. Non-metastatic and resectable disease, 5. No prior treatment for the disease under study, 6. Age ≥ 18 years, 7. Life expectancy ≥ 3 months, 8. Eastern Cooperative Oncology Group (ECOG) performance status (PS) ≤ 1, 9. Patients must have measurable disease (lesion in previously irradiated field can be considered as measurable if progressive at inclusion according to RECIST 1.1) defined as per RECIST v1.1 with at least one lesion that can be measured in at least one dimension (longest diameter to be recorded) as ≥ 10 mm or ≥ 15mm in case of adenopathy, 10. Women of childbearing potential must have a negative serum pregnancy test before study entry. Both women and men must agree to use a medically acceptable method of contraception throughout the treatment period and for one year after discontinuation of treatment. Acceptable methods of contraception include intrauterine device (IUD), oral contraceptive, subdermal implant and double barrier. Subjects of childbearing potential are those who have not been surgically sterilized (e.g., vasectomy for males and hysterectomy for females) or have not been free from menses for ≥ 1 year, 11. Voluntarily signed and dated written informed consents prior to any study specific procedure, 12. Patients with a social security in compliance with the French law. Exclusion Criteria : 1. Soft-tissue sarcoma with the following histological subtypes: well-differentiated liposarcoma, alveolar soft-part sarcoma, dermatofibrosarcoma protuberans, clearcell sarcoma, embryonal and alveolar rhabdomyosarcoma, 2. Prior or concurrent malignant disease diagnosed or treated in the last 2 years except for adequately treated in situ carcinoma of the cervix, basal or squamous skin cell carcinoma, or in situ transitional bladder cell carcinoma, 3. Any other contraindication to anthracycline, ifosfamide or dacarbazine chemotherapy, 4. Participation to a study involving a medical or therapeutic intervention in the last 28 days, 5. Known infection with HIV, hepatitis B, or hepatitis C, 6. Females who are pregnant or breast-feeding, 7. Other medical conditions may interfere with the conduct of the study and, in the judgment of the investigator, would make the patient inappropriate for entry into this study, 8. Individuals deprived of liberty or placed under legal guardianship, 9. Unwillingness or inability to comply with the study protocol for any reason. Additional criteria for randomization : 1. High-risk CINSARC signature, 2. No more than two cycle of neo-adjuvant anthracycline-based chemotherapy before randomization.
