Finding treatments for breast cancer is a major goal for scientists.1,2 Some classes of drugs show more promise than others. Gradishar evaluated taxanes as a class.3 Other scientists have investigated individual drugs within this class, including Andre and Zielinski 2 and Joensuu and Gligorov. 4 Mita et al's investigation of cabazitaxel 5 seems to indicate a new role for this class of drugs.
