The role of taxane-based chemotherapy in the treatment of prostate cancer.

Overview

PURPOSE OF REVIEW: Indications for chemotherapy have increased in prostate cancer (PCA), many of which are shared with new hormonal agents (NHA). With no head to head comparison available, defining the optimal sequence and identifying biomarkers to predict response, has been a focus of intense research in PCA. We aim to summarize the best currently available evidence in all stages of disease to help guide therapy. RECENT FINDINGS: In metastatic castration-resistant prostate cancer, Cabazitaxel has shown improved radiographic progression-free survival over another NHA after Docetaxel and one NHA. For hormone sensitive PCA (mHSPC) multiple meta-analyses have shown combination therapy with Docetaxel or an NHA to be superior to androgen deprivation therapy alone, yet no clear benefit over each other. For peri-interventional chemotherapy with local therapy, there is currently only one positive prospective trial, for very high-risk disease. SUMMARY: Cabazitaxel is underutilized and should be used earlier. NHAs should not be used in succession as there is significant cross resistance. Combination therapy should be used in mHSPC, yet there is no clear benefit for any combination. Peri-interventional chemotherapy might have a benefit for a small group of patients with very high-risk disease, yet this must be carefully evaluated, and side effects must be taken into account.
