Testosterone therapy may be linked to prostate cancer development. Early detection through digital rectal exams and PSA testing is crucial for men on testosterone supplementation.

Area of Science:

  • Urology
  • Oncology
  • Endocrinology

Background:

  • The association between testosterone supplementation and prostate cancer remains debated.
  • Increased use of testosterone therapy necessitates evaluating its safety in at-risk populations.

Purpose of the Study:

  • To raise awareness of potential prostate cancer risks associated with testosterone supplementation.
  • To report on a series of patients who developed clinically significant prostate cancer presumed to be related to exogenous testosterone use.

Main Methods:

  • Retrospective review of medical records from six urology practices.
  • Identification of men diagnosed with prostate cancer after initiating testosterone supplementation for sexual dysfunction or rejuvenation.
  • Analysis of clinical and pathological parameters of prostate cancer presentation.

Main Results:

  • Twenty men were diagnosed with prostate cancer post-testosterone initiation, with detection within two years in 55% of cases.
  • Tumors were predominantly of moderate to high grade (Gleason sum 6-10).
  • Median prostate-specific antigen (PSA) levels were often low (5.1 ng/ml), with digital rectal examination proving more sensitive for detection.

Conclusions:

  • Prostate cancer can manifest within months to years of starting testosterone treatment.
  • Digital rectal examination is vital for detecting these cancers.
  • Frequent PSA testing and digital rectal examinations are recommended for patients on testosterone supplementation.
