The approval of docetaxel chemotherapy in prostate cancer treatment ushered in an era in which improvement in OS became a well-defined, achievable end point. However, resistance still occurs, and responses are limited in men with mCRPC. There is a continuing need to understand varying mechanisms of resistance and ways to overcome them. In order to better understand tumor biology and mechanisms of chemoresistance, pre- and postchemotherapy molecular analyses of tumor genomic material are critical. Additionally, the mechanisms of resistance to chemotherapy following administration of other classes of agents, such as anti-androgen agents, may also be applicable considering the cross-resistance between them. Rational selection of patients is also important to produce large increments and to develop precision medicine.
