CARMMYC: Circulating Cancer Cells/Macrophage HYbrid Cells in Patients With Breast Cancer.
Study Details
Study Description
Brief Summary
Pilot, prospective, monocentric study aimed at evaluating the rate of patients with circulating cancer cell/macrophage hybrid cells in the peripheral blood.
The study will be conducted on a population of patients with breast cancer (regardless of stage of the disease and the immunohistochemical subtype).
For each included patient, blood samples will be taken and tumor specimens will be collected for the study.
At the end of the blood collection, the patient will have completed his participation in the study.

Other: Patients with breast cancer (stage I, II III or IV)
Blood samples will be collected at different times:
at Baseline for all patients with breast cancer: before initiation of treatment (i.e. before initiation of planned treatment for stage I to III patients and before any new line of treatment for stage IV patients);
at the time of disease progression (or at 12 months in absence of progression) for patients with metastatic breast cancer (stage IV)
For each patient a tumor sample from the initial diagnosis of the disease (i.e. primary tumor +/- biopsy of a metastasis) will be collected (archived tumor block) for the study.

Outcome Measures
Primary Outcome Measures
- Rate of patients with cancer cell / macrophage hybrid cells in peripheral blood defined as the ratio of the number of patients with hybrid cells to the total number of patients. [20 months after the study start]
Secondary Outcome Measures
- Quantification of circulating hybrid cells in peripheral blood by automatic measurement (Cell Counter Corning) and expressed in number of cells / millilitre of blood. [20 months after the study start]
- Progression-free survival (PFS) defined as the time from the date of inclusion to the date of progression or death from any cause. [20 months after the study start]
