Cancer cells, like non-malignant cells, are dependent on folate uptake for growth. However, cancer cells are much more reliant on folate receptors (FRs) and particularly FRα for folate uptake than non-malignant cells. In this Review, the authors describe the available data on the role of FRα as a biomarker and as a target of imaging probes, and of targeted therapies in patients with solid tumours.
