摘要

Are current cancer drugs targeted at the wrong kinds of cells? A pioneering approach to the development of treatments uses a mathematical model to follow how different types of tumour cells respond to therapy. In this issue, Michor and colleagues (page 1267)' address the vexing problem that although many cancer drugs dramatically reduce the size of tumours, most cancers will eventually recur, often fatally. The authors model the dynamic changes in populations of cancer cells during treatment, and their data fit with the theory that there is a small population of cells - 'cancer stem cells' - that are ultimately responsible for the growth of tumours and are resistant to current therapies. Furthermore, the results imply that these cells may provide areservoir for the generation and propagation of mutant cells that are also resistant to therapy. This innovative modelling strategy should allow prospective evaluation of drugs aimed at eradicating cancer stem cells.
