Clinical Trial Summary

Pilot, prospective, monocentric study aimed at evaluating the rate of patients with circulating "cancer cell/macrophage" hybrid cells in the peripheral blood and the evolution of this rate over time.

The study will be conducted on a population of patients with leiomyosarcoma and treated in the context of routine care. 20 patients will be included:

• 10 patients with localized disease.

• 10 patients with metastatic disease.

For each included patient, blood samples will be collected during baseline visit and up to 24 months after inclusion.

2. Associated pathology(ies) that may interfere with the study procedure

3. Pregnant or breastfeeding woman

4. Any psychological, family, geographical or sociological condition that does not allow for compliance with the medical follow-up and/or procedures provided for in the study protocol.

5. Patient who has forfeited his/her freedom by administrative or legal award or who is under legal protection (curatorship and guardianship, protection of justice).

Intervention

Other:
• Blood samples will be collected at different times.
For patients with localized leiomyosarcoma, samples will be collected: At Baseline. Before surgery (for patients who have had neoadjuvant treatment (external radiotherapy and/or chemotherapy)). After surgery. At each control visit. At local or metastatic recurrence (or at 24 months post inclusion if no progression). For patients with metastatic leiomyosarcoma, samples will be collected: At Baseline. At each therapeutic line. At progression (or at 24 months post inclusion if no progression).

Type	Measure	Description	Time frame	Safety issue
Primary	The longitudinal evolution of rate of patients with "cancer cell / macrophage" hybrid cells in peripheral blood.		24 months after the end of inclusions.
Secondary	Quantification of circulating hybrid cells in peripheral blood by automatic measurement (Cell Counter Corning) and expressed in number of cells / millilitre of blood.		24 months after the end of inclusions.
