Promising but preliminary

Circulating tumour cell-derived xenograft as a preclinical platform for metastatic breast cancer

A patient's circulating tumor cells successfully grew into tumors in mice and responded to specific drugs, demonstrating a potential personalized drug-testing platform.

A CTC-derived xenograft from a single metastatic breast cancer patient was successfully established, enriched in breast cancer stem cells, and showed sensitivity to carboplatin and vandetanib in vitro and in vivo. While a promising preclinical platform concept, this is a single patient derivation with no clinical outcomes data.

Why it surfaced

Preclinical model development from single patient. British Journal of Cancer. Too preliminary for pipeline-ready insights. Score capped at 5 for non-human study (xenograft in mice); further reduced to 4 given single-patient source.
