INTRODUCTION: Anemia is frequently associated with cancer due to the disease itself and antineoplastic treatments. This open-label, uncontrolled, multi-center study evaluated the effects of once-weekly (qw) epoetin alfa 40,000 IU on hemoglobin (Hb) levels and quality of life (QoL) in anemic patients receiving chemotherapy for solid tumors. MATERIALS AND METHODS: A total of 522 patients with Hb level < or =12 g/dL received epoetin alfa 40,000 IU qw subcutaneously for 9-20 weeks to reach and maintain Hb range of 12-14 g/dL. QoL was assessed with the Functional Assessment of Cancer Therapy-Anemia (FACT-An [anemia sub-scale]) and Cancer Linear Analogue Scale (CLAS) at study entry, after two chemotherapy cycles, and at study end. RESULTS: Mean baseline Hb was 10.43 g/dL. Hb increases (g/dL) from baseline after 4, 8, 12 weeks and at study end were 1.07, 1.77, 1.92 and 1.71 g/dL, respectively. Response rates (Hb increase > or =1 and > or =2 g/dL during trial) were 81% and 61%, respectively. Mean increases in the FACT-An score from baseline (mean 55.4) were 3.1 after two chemotherapy cycles and 3.3 at study end; mean increases in the CLAS score from baseline (58.4 mm) were 5.9 mm after two chemotherapy cycles and 6.5 mm at study end. DISCUSSION: The greatest QoL increase was recorded when patients approached Hb level of 12 g/dL, independent of the baseline Hb level. Hb changes from baseline to trial end were related to corresponding changes in the FACT-An score. A positive correlation was also observed in patients with progressive disease. Adverse events were essentially those associated with chemotherapy. Incidence of thrombovascular events (6.7%) did not differ from the expected standard treatment in cancer patients. Epoetin alfa 40,000 IU qw increased Hb levels and improved or preserved QoL.
