The study of mitotic transduction of the signal showed that overexpression of pAkt and reduction in pERK expression would be associated a biological relapse. For tumors T1-3 N0M0 at the high risk of local relapse after prostatectomy, an immediate radiotherapy compared with a differed radiotherapy (at the time of PSA relapse), showed a significant reduction in the rate of local relapse and an ameliorated progression free survival. The effectiveness of the docetaxel was confirmed in two phase III randomized clinical trials : TAX-327 with 3 arms compared docetaxel every 21 days, docetaxel every 7 days and mitoxantrone. All arms were prednisone-based. An increase in overall survival, PSA progression free survival, PSA response rate and a pain reduction were highlighted in the docetaxel arm every 21 days. Docetaxel obtained at the end of this study the marketing authorization in this indication and became the treatment of reference. The SWOG 99-16 study compared the docetaxel estramustine association with the same arm of reference, mitoxantrone and prednisone, with similar results. The addition of estramustine to the docetaxel seems to improve the PSA response rate and progression free survival, but with a greater embolic toxicity. The addition of an antiangiogenic agent, the thalidomide, to docetaxel, improves progression free survival and overall survival. PSA responses were observed with an inhibitor of the proteasome, the bortezomib, in monotherapy, contrary to the imatinib which in monotherapy didn't have any effectiveness. Studies in association with docetaxel are ongoing. Some biological responses were observed with a vaccine anti MUC-1 and must be confirmed on a greater series of patients. The docetaxel impact on localized disease is actually evaluated.

Most men with metastatic prostate cancer respond to various types of androgen ablation but progress to castration-resistant disease. The TAX 327 and Southwest Oncology Group (SWOG) 99-16 clinical trials established docetaxel-based chemotherapy as preferred first-line treatment for most men with symptomatic metastatic castration-resistant prostate cancer (mCRPC). However, only about half receive benefit from docetaxel, and those who respond initially progress and eventually die of (or with) mCRPC. Both cellular mechanisms and the tumor microenvironment are implicated in the development of resistance to docetaxel. New agents are being evaluated for men with mCRPC, either as first-line treatment in combination with docetaxel, or in men progressing during or after treatment with docetaxel. Thus far, agents evaluated in phase III trials in combination with docetaxel have not improved outcome, including the vaccine GVAX, high-dose vitamin D (DN-101), and the antiangiogenic agent bevacizumab. In contrast, cabazitaxel, a taxane that is not cross-resistant to docetaxel, substantially improved the outcome of men progressing during or after treatment with docetaxel-based chemotherapy when compared with mitoxantrone and prednisone. However, translation of benefit of cabazitaxel demonstrated in the TROPIC (Treatment of Hormone-Refractory Metastatic Prostate Cancer) trial into general oncologic practice will be challenging because this agent may cause serious toxicity. With the approval of less toxic hormonal agents (eg, abiraterone acetate) in the setting of docetaxel-resistant mCRPC, clinicians will have an opportunity to balance benefits and harms of new agents in an individual patient and may be able to use different agents in sequence.
