Gene-directed enzyme prodrug therapy involves tumor-specific delivery of a gene encoding a drug-metabolizing enzyme allowing metabolism of a non-toxic prodrug to a toxic species directly within tumor cells. This review covers the wide range of enzyme-prodrug combinations currently under preclinical and clinical investigation. Issues of tumor specificity and enhanced cytotoxicity through bystander effects will be discussed.
