Recombinant Human Erythropoietin Treatment in Elderly Cancer Patients with Cisplatin–Associated Anemia

Abstract
The efficacy of recombinant human erythropoietin (rHuEPO) on the increase in hemoglobin levels was assessed in patients with cisplatin (CDDP)-induced anemia older than 70 years. Furthermore, we compared the results obtained in this group of patients with those observed in other patients receiving rHuEPO for a CDDP-associated anemia with similar clinical features (chemothera-peutic regimen, primary tumor; CDDP cumulative dose) but of an age less than 70 years. Twenty patients older than 70 years with a CDDP-associated anemia (hemoglobin levels < 90 g/l) received rHuEPO at the dose of 100 U/kg subcutaneously, three times a week. The control group consisted of 20 younger patients, anemic after CDDP chemotherapy, treated with rHuEPO. All patients were evaluable for response and toxicity. Hemoglobin concentrations showed a statistically significant increase after the 3rd, 6th and 9th week of therapy in both older (93.1 ± 10.7,103.5 ± 8.2 and 102.7 ± 8.2, respectively, vs. baseline, 84.6 ± 4.9) and younger patients (95.3 ± 11.7,101.5 ± 13.4and 101.9 ± 8.7, respectively, vs. baseline, 86.6 ± 4.0). Furthermore, 30% of older patients required blood transfusions versus 35% of younger patients, with the mean unit of blood transfused per patient being 0.7 U in elderly and 0.65 U in younger patients. Treatment was well tolerated with no significant side effects. The CDDP-induced anemia seems to be corrected by rHuEPO also in elderly patients, without differences with respect to younger patients.
