Testosterone Therapy in Men with Prostate Cancer – new research

Testosterone Therapy in Men with Prostate Cancer – new research

Testosterone Therapy in Patients with Treated and Untreated Prostate Cancer: Impact on Oncologic Outcomes. Ory J, Flannigan R, Lundeen C, Huang JG, Pommerville P, Goldenberg SL. J Urol. 2016;196(4):1082-1089.

Historically, prostate cancer – both active and treated - has been an absolute contraindication to testosterone therapy and – from a regulatory perspective – still is. The incidence of prostate cancer is higher in older men, in whom prostate cancer accounts for one in five new cancer diagnoses. Thanks to improvement in early detection and treatment of prostate cancer, prostate cancer mortality has decreased 50% during the past two decades, and more men are living with a history of prostate cancer.

The aging of the male population and the increasing number of prostate cancer survivors have resulted in a significant increase in the number of men presenting with hypogonadism and treated prostate cancer. Therefore, it is important to consider the growing number of recent studies which have challenged the long-standing belief that prostate cancer is an absolute contraindication to testosterone therapy. Here we summarise the results of a notable study which investigated the effects of testosterone therapy in men with treated and untreated prostate cancer, and conclude with the latest recommendations on managing testosterone deficiency in men with history of prostate cancer.

Key Points

  • An initial increase in PSA when starting testosterone therapy is normal and is not synonymous with prostate disease progression.
  • Emerging research shows that testosterone therapy in men after radical prostatectomy or radiation, and in men on active surveillance, in most cases does not cause prostate cancer recurrence or worsening.
  • The risk of prostate cancer recurrence appears to be lower after radical prostatectomy than after radiation.

Testosterone and Prostate Cancer - a paradigm shift

Testosterone and Prostate Cancer - a paradigm shift

"Bye-bye Androgen Hypothesis, Welcome Saturation Model"

A new era of testosterone and prostate cancer: from physiology to clinical implications. Khera M, Crawford D, Morales A, et al., Eur Urol 2014; 65(1): 115-23.

A long-held belief is that testosterone stimulates development of prostate cancer (PCa) and/or accelerates its growth. This summary gives an overview of an in-depth review of current literature regarding the relationship of serum testosterone and PCa and the effect of testosterone replacement therapy (TRT) on PCa progression and recurrence. Key studies which have refuted the old belief that testosterone has harmful effects on the prostate are presented, along the new testosterone-prostate paradigm known as the saturation model.
