Summary
Brief summary (as posted)
This trial is a pilot, prospective, single-center study conducted in a population of patients with metastatic breast cancer (whatever the immunohistochemical subtype) or metastatic prostate cancer. The aim of this exploratory study is to compare the sensitivity of three different techniques (CellSearch®, Parsortix® and SmartCatch®) in detecting circulating tumor cells (CTCs). After the patient's agreement, and before starting anti-tumor treatment, a blood sample will be taken using the 3 different CTC detection techniques. Each patient will participate in the study for one day. A total of 54 evaluable patients (36 patients with metastatic breast cancer and 18 patients with metastatic prostate cancer) will be included in this interventional study.
