Innovative therapies for prostate cancer treatment.
Androgen ablation is effective therapy for metastatic prostate cancer, but the majority of men eventually become refractory to this intervention. Cytotoxic chemotherapy offers palliation to symptomatic patients with hormone-refractory prostate cancer (HRPC); however, no chemotherapy regimen has yet been shown to prolong survival. There is a clear need for new agents and drug targets for the treatment of HRPC. A number of innovative therapeutic approaches that are rationally based and target driven are under investigation. This article reviews the development of antisense oligonucleotides that inhibit the anti-apoptotic bcL-2 protein. Approaches that target the epidermal growth factor receptor, the platelet derived growth factor receptor, and nuclear factor kappa-B are also discussed. There is much expectation that these therapies alone or in combination with cytotoxic chemotherapy will impact the clinical outcome of patients with HRPC.
