Critical appraisals of approaches for predictive designs in anticancer drugs.
The present review provides a critical appraisal of the most important areas in cancer drug research and, ultimately, in clinical oncology and therapy, with emphasis on the elucidation of possible predictive designs for the development of new anticancer drugs. These assessments encompass the well-established anticancer drugs and congeners which have been employed over the years in clinical therapy, and the more recent exploratory agents still requiring further rigorous scrutiny in the clinical environment. These areas mainly include the bioreversible redox carriers, the boron neutron capture compounds, some new mitosis-interactive agents, cell cycle modifiers, biological-response mpdifiers, oncogene inhibitors, drug-antibody conjugates, cancer cell suppression and destruction agents, antiangiogenesis and antimetastasis agents, apoptosis-promoting agents, and gene therapy and vaccines.
