Effect of age on hemoglobin levels and quality of life following treatment with epoetin alfa in cancer patients.

A subgroup analysis comparing elderly (age > or =70 years; n=95) with younger (age <70 years; n=390) patients was performed on data from a prospective, multicenter, open-label study assessing the effects of once-weekly epoetin alfa 40,000 International Units (IU) for 16-20 weeks on hemoglobin (Hb) levels and quality of life (QoL) in anemic adult patients undergoing chemotherapy for solid tumors. There were significant increases in mean Hb levels at 4, 8, 12, 16-20 weeks in both age groups (p<0.0001), but no significant differences between groups (p=0.7). No significant difference was observed in terms of blood transfusion rates across the study between elderly and younger patients (3.2% vs 6.7%, p=0.2). Although QoL was lower in elderly patients at baseline, the relative percentage increases in QoL scores during treatment were similar for both age groups. Thus, once-weekly epoetin alfa was equally effective in treating chemotherapy-related anemia in elderly and younger adult patients, with similar tolerability.
