Anemia in patients on combined androgen block therapy for prostate cancer / 中华肿瘤杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of combined androgen block therapy on hemoglobin (Hb) and hematocrit value (Ht) in patients with prostate cancer.</p><p><b>METHODS</b>One hundred and thirty-six patients with adenocarcinoma of the prostate were treated with combined androgen block (orchiectomy and flutamide 250 mg, Tid). Complete blood counts were detected before initiation and after 1, 2, 3, 6, 9 and 12 months of therapy.</p><p><b>RESULTS</b>Hb level declined significantly in all patients from a mean baseline of (136 +/- 14) g/L to (126 +/- 16) g/L, (121 +/- 14) g/L, (120 +/- 15) g/L, (113 +/- 12) g/L, (121 +/- 13) g/L and (123 +/- 15) g/L at 1, 2, 3, 6, 9 and 12 months. Ht decreased from a mean baseline of 0.424 +/- 0.041 to 0.390 +/- 0.038, 0.381 +/- 0.042, 0.378 +/- 0.038, 0.366 +/- 0.041, 0.384 +/- 0.039 and 0.387 +/- 0.040. The differences between Hb, Ht before and after treatment were significant (P < 0.05).</p><p><b>CONCLUSION</b>Patients with prostate cancer being treated with combined androgen block would develop a significant degree of anemia. Hemoglobin and hematocrit level should be monitored periodically. This kind of anemia can be treated by recombinant human erythropoietin.</p>
