Interest of post-operative chemotherapy in patients with localized uterine leiomyosarcoma suspected to have a high-risk of relapse based on a biologic test performed on the tumor.
EU CTIS ID: 2023-506350-21-00
What this study is testing
To demonstrate that adding 4 cycles of adjuvant post-operative doxorubicin+trabectedin chemotherapy improves relapse-free survival (RFS) as compared with standard management (observation) in patients with resected FIGO stage I uLMS, considered as HR according to CINSARC NanoCind® signature.
- Therapeutic exploratory (Phase II)

Who can take part
You may be able to join if
- Patient must have a histologically confirmed diagnosis of uterine leiomyosarcoma obtained less than 8 weeks from the surgery
- For randomization : Inclusion criteria checked at study entry are all still met at the time of randomization
- For randomization : High-risk CINSARC signature
- For randomization : Patient must have a diagnosis of uterine leiomyosarcoma confirmed by a local sarcoma expert pathologist from RRePS (Sarcoma Pathology Refernce Netword from NETSARC +) locally or by the study central RRePS expert pathologist.
- For randomization : Adequate hematologic organ function: - absolute neutrophil count ≥ 1.5 Giga/ L - hemoglobin ≥ 9 g/dL - platelets ≥ 100 Giga/L
- For randomization : Adequate renal function: serum creatinine ≤ 1.5 mg/dL (≤ 132.6 μmol/L) or calculated creatinine clearance ≥60 mL/min (by the Cockcroft and Gault formula)
You likely can't join if
- All other histology types of uterine sarcoma (adenosarcoma, endometrial sarcoma, undifferentiated uterine sarcoma)
- For randomization : More than 13 weeks have elapsed since the surgery procedure.
- Prior or concurrent malignant disease diagnosed or treated in the last 5 years except for adequately treated in situ carcinoma of the cervix, basal or squamous skin cell carcinoma, or in situ transitional bladder cell carcinoma
- Planned pelvic post-operative radiation therapy
- Metastatic or measurable disease on CT-Scan
- Known hypersensitivity to doxorubicin or trabectedin or to any of the excipients
