Prazosin but Not Tamsulosin Sensitises PC-3 and LNCaP Prostate Cancer Cells to Docetaxel.

Summary of "Prazosin but Not Tamsulosin Sensitises PC-3 and LNCaP Prostate Cancer Cells to Docetaxel."

Docetaxel is currently the first-line chemotherapeutic agent available for the treatment of patients with advanced prostate cancer (PCa). While docetaxel has been shown to modestly improve survival times for patients; they also experience significant docetaxel-induced toxicities. If treatment failure occurs, there are currently limited alternatives that show survival benefits for patients and therefore there is an urgent need for adjunct therapies. Some quinazoline-based alpha1-adrenoceptor (ADR) antagonists have previously been shown to have cytotoxic actions in PCa cells, but there is no research into their effects on docetaxel-induced toxicity. Therefore, the aim of this study was to determine if the quinazoline ADR, prazosin influenced the sensitivity of PCa cells to docetaxel in vitro. We hypothesised that prazosin, but not tamsulosin, in combination with docetaxel would possess synergistic cytotoxic actions on PC-3 and LNCaP PCa cells.
