Androgen deprivation for prostatic carcinoma: a rationale for choosing components

Abstract

Ever since prostatic carcinoma was discovered to be dependent on the hormone androgen for its proliferation, androgen deprivation has been the treatment of choice for advanced cases of prostate cancer. Originally, treatment was limited to surgical castration or estrogen therapy. However, the introduction of luteinizing hormone-releasing hormone analogues, antiandrogens, and newer treatment modalities, such as combined androgen blockade, has made choosing a treatment strategy more complex. Assuming that each modality is equally effective, emphasis should be placed on increasing patient tolerance and compliance by the use of long-acting, nontoxic treatments with simple dosing regimens and minimal side effects. This review focuses on the factors influencing the final choice of treatment strategy.
