Orchiectomy does not selectively increase adrenal androgen concentrations.

L Parker, M Lai, F Wolk

    The Journal of Clinical Endocrinology and Metabolism

    Summary

    Orchiectomy for prostate cancer does not increase adrenal androgens. This study found no evidence that adrenal androgen levels rise after orchiectomy, suggesting it does not promote tumor recurrence.

    Area of Science:

    • Oncology
    • Endocrinology

    Background:

    • Prostatic carcinoma is androgen-dependent, making orchiectomy a common treatment.
    • Adrenal androgen secretion persists post-orchiectomy, raising concerns about potential tumor recurrence.

    Purpose of the Study:

    • To investigate whether adrenal androgen concentrations increase after orchiectomy for prostatic carcinoma.
    • To determine if elevated adrenal androgens post-orchiectomy could theoretically promote tumor recurrence.

    Main Methods:

    • Collected serial blood samples from 10 men before and up to 6 months after orchiectomy.
    • Measured serum testosterone, dehydroepiandrosterone (DHA), dehydroepiandrosterone sulfate (DHAS), and cortisol levels.

    Main Results:

    • Serum testosterone became undetectable post-orchiectomy.

    Related Experiment Videos

  • While three patients showed transient increases in DHA and cortisol due to surgical stress, mean serum DHA and DHAS did not increase overall.
  • Adrenal androgen levels returned to preoperative values in all patients.

    • Conclusions:

    • The study found no evidence to support the hypothesis of increased adrenal androgen concentrations after orchiectomy.
    • Results suggest that orchiectomy does not lead to a significant rise in adrenal androgens that could fuel prostate cancer recurrence.
