Chemohormonal and immunohormonal approaches in advanced prostatic carcinoma.

The standard palliative treatment for patients with advanced prostate cancer has for the past 50 years been androgen withdrawal. However, owing to the presence of hormone-insensitive cell clones, the benefits of this approach have now appeared to reach their optimum. It is now generally believed that further major therapeutic advances in the treatment of prostate cancer are unlikely, unless consideration is given to these hormonally independent cells. Two possible alternative strategies which address this problem are chemohormonal and immunohormonal approaches, both of which are discussed in detail in this article.
