Bilateral orchiectomy, a prostate cancer treatment, significantly lowers hemoglobin levels in men, potentially causing normocytic anemia. This finding helps avoid unnecessary diagnostic tests for anemia post-surgery.

Area of Science:

  • Urology
  • Hematology
  • Endocrinology

Background:

  • Bilateral orchiectomy reduces testosterone production.
  • Testosterone reduction may lead to normocytic anemia.
  • The effect of orchiectomy on hemoglobin is not well-documented.

Purpose of the Study:

  • To determine the impact of bilateral orchiectomy on hemoglobin concentration.
  • To investigate the incidence of normocytic anemia following orchiectomy.
  • To inform clinical practice regarding anemia in patients undergoing orchiectomy.

Main Methods:

  • Retrospective analysis of 64 prostate cancer patients undergoing bilateral orchiectomy.
  • Inclusion criteria: normal preoperative blood counts, normal creatinine, no disease progression, and normal mean corpuscular volume post-surgery.

  • Hemoglobin, prostate-specific antigen, and creatinine levels measured preoperatively and postoperatively (>90 days).

    • Main Results:

    • A median decrease of 1.2 g/dL in hemoglobin concentration was observed post-orchiectomy.
    • Statistically significant reductions in hemoglobin were noted at all postoperative intervals.
    • The decrease in hemoglobin was both clinically and statistically significant.

    Conclusions:

    • Bilateral orchiectomy causes a significant decrease in hemoglobin concentration.
    • This decrease can lead to normocytic anemia in men.
    • Awareness of this effect can prevent unnecessary diagnostic workups for anemia after orchiectomy.
