Replica tumors show promise for personalized drug treatment

Recently published in Science, researchers at The Institute of Cancer Research (London, UK) and The Royal Marsden NHS Foundation Trust (London, UK) have demonstrated how growing replica tumors in the lab could personalize drug treatment.

The study, led by Nicola Valeri (The Institute of Cancer Research), first took biopsy samples from 71 patients with advanced bowel, gastro-esophageal or bile duct cancers, whose tumor had metastasized round the body.
