Evolution of hormonal therapy for prostate cancer.

Abstract

Prostate cancer (PCa) is the most common malignancy after skin cancer in men in Australia. Its management varies according to tumour stage. Due to the significant dependence on androgen receptor signalling, agents that interfere with this pathway (most commonly medical castration in the form of androgen deprivation therapy [ADT]) are the mainstay treatment of advanced disease. This review provides a contemporary update on ADT, withfurther discussion of emerging novel therapies for primary care. ADT is currently indicated for the treatment of metastatic prostate cancer, disease recurrence following attempted local curative therapy, as well as combined use with radiotherapy for intermediate/high-risk disease. There has been rapid development of new pharmaceuticals targeting the androgen receptor. These are reviewed historically with an emphasis placed on emerging therapies, their common side effects, and how to managethem in the general practice setting.
