RECOMBINANT-HUMAN-ERYTHROPOIETIN TREATMENT IN ELDERLY CANCER-PATIENTSWITH CISPLATIN-ASSOCIATED ANEMIA

The efficacy of recombinant human erythropoietin (rHuEPO) on the incre ase in hemoglobin levels was assessed in patients with cisplatin (CDDP )-induced anemia older than 70 years. Furthermore, we compared the res ults obtained in this group of patients with those observed in other p atients receiving rHuEPO for a CDDP-associated anemia with similar cli nical features (chemotherapeutic regimen, primary tumor; CDDP cumulati ve 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) rec eived rHuEPO at the dose of 100 U/kg subcutaneously, three times a wee k. The control group consisted of 20 younger patients, anemic after CD DP chemotherapy, treated with rHuEPO. All patients were evaluable for response and toxicity. Hemoglobin concentrations showed a statisticall y significant increase after the 3rd, 6th and 9th week of therapy in b oth older (93.1 +/- 10.7, 103.5 +/- 8.2 and 102.7 +/- 8.2, respectivel y, vs. baseline, 84.6 +/- 4.9) and younger patients (95.3 +/- 11.7, 10 1.5 +/- 13.4 and 101.9 +/- 8.7, respectively, vs. baseline, 86.6 +/- 4 .0). Furthermore, 30% of older patients required blood transfusions ve rsus 35% of younger patients, with the mean unit of blood transfused p er patient being 0.7 U in elderly and 0.65 U in younger patients, Trea tment was well tolerated with no significant side effects. The CDDP-in duced anemia seems to be corrected by rHuEPO also in elderly patients, without differences with respect to younger patients.
