Combined Therapies with Taxane-Based Chemotherapeutic Drugs in Prostate Cancer: Novel Insights and Future Directions

Oncologic disease is a significant global health issue that causes thousands of deaths annually, and it has a significant impact on the quality of life of patients. Prostate cancer (PCa) is the second most diagnosed cancer and the fourth leading cause of cancer-related death in men in the Western world. Delineation of pathogenetic pathways and key driver molecular alterations involved in PCa development has provided a roadmap for the evaluation of biomarkers in predicting disease outcome and to identify potential therapeutic targets. Chemotherapeutic agents introduced from the 1990s include the taxanes (paclitaxel, docetaxel, and cabazitaxel), which are the anticancer drugs used most frequently for PCa treatment. This review presents the current knowledge about the onset and development of PCa, the state of the art of the use of taxane-based therapy, and their combination with targeting different transmembrane oncoproteins in PCa. The silencing of some transmembrane proteins can improve taxane sensitivity, and therefore may be a mechanism to improve the effectiveness of these drugs in PCa treatment. This combined therapy needs to be explored as a potential therapeutic agent for reducing cell proliferation, migration, and invasiveness in PCa.
