Summary

After more than two decades of extensive use, drugs based on platinum continue to have a major role in cancer treatment. Although systematic approaches to the development of new analogues have produced agents with less toxicity and novel mechanisms of action, to date such approaches have not achieved more cures than can be achieved with the parent compound, cisplatin. Greater gains might be expected from accumulating knowledge about what makes cancer cells sensitive or resistant to platinum-based chemotherapy. Recent information on drug-efflux pathways, including expression of multidrugresistance protein 2, and on how tumour cells behave when their DNA is distorted by a platinum adduct, suggests new avenues for translational research. The prospects include modulation of cellular handling of platinum compounds and individualised therapy based on expression of molecules that determine platinum sensitivity.
