Chemotherapy for prostate cancer: implementing early systemic therapy to improve outcomes

Prostate cancer remains a significant health concern for men in the USA as it is a leading cancer diagnosis and a cause of death. With the use of prostate-specific antigen or screening, a stage migration has occurred with an increase in the number of men diagnosed with early-stage disease. The optimal primary management of these men is evolving, but despite adequate local treatment a significant percentage will develop either biochemical or clinical evidence of recurrent disease. Several criteria for risk stratification have been developed, thus, improving the ability to identify a high-risk population. Small studies have been reported demonstrating the feasibility of neoadjuvant or adjuvant chemotherapy in conjunction with either radiation or radical prostatectomy in this high-risk population, and large phase III studies are ongoing. With the advent of life-prolonging chemotherapy in the hormone-refractory setting, attention must now also be given to early-stage disease so as to develop multi-modality approaches with the hope of increasing survival and ultimately providing a cure.
