In this episode, Ted provides insights into the role testosterone plays, or doesn't play, in the initiation and progression of prostate cancer. He unpacks the findings and limitations of the recent TRAVERSE trial, exploring the complex relationship between testosterone and prostate cancer. Ted delves into the molecular nature of prostate cancer, explaining the androgen receptor saturation theory and the potential impact of testosterone on cancer growth. He also discusses the use of the Decipher test to predict cancer aggressiveness and guide targeted treatment. Furthermore, Ted shares how he counsels patients regarding testosterone replacement therapy (TRT), including its safe administration in patients with low-grade prostate cancer. Additionally, he highlights advancements in prostate cancer therapies and biomarkers that help develop precise treatment strategies while minimizing the need for broad androgen deprivation therapy.
