Circulating Tumor Cells (CTC) in Cancer

March 10, 2025 updated by: University Hospital, Basel, Switzerland
This observational study with circulating tumor cells (CTC) count, isolation and analysis at several time points during disease progression is to investigate the role and biology of CTCs and clusters of CTCs in different cancer types. It also evaluates the role of CTCs as biomarkers, and aims at the identification of key signaling networks that are active in CTCs.
