Efficacy of Darbepoetin alfa in Anemia Developed during Chemotherapy for Lung Cancer / 결핵및호흡기질환

ABSTRACT

BACKGROUND: Anemia is quite common in lung cancer patients and known to decrease the quality of life. Darbepoetin alfa is an erythropoiesis-stimulating protein approved for administration to cancer patients. This study examined the efficacy and safety of darbepoetin alfa in lung cancer patients with a hemoglobin concentration 10 g/dl. The efficacy and safety were measured by comparing the hemoglobin concentration and assessing the adverse events. RESULTS: After chemotherapy, the hemoglobin concentration decreased to 9.03+/-0.64 g/dl. With the darbepoetin alfa treatment, the hemoglobin concentration increased to 10.09+/-1.17 g/dl after 4 weeks reaching a peak hemoglobin concentration of 10.45+/-1.18 g/dl. The changes in hemoglobin after 4 and 8 weeks with treatment were 1.08+/-1.24 g/dl and 1.38+/-1.59 g/dl (p<0.01). At least a 1 g/dl or more increase in hemoglobin was observed in 62.4% of patients. There were no serious adverse effects except for some mild reactions. CONCLUSION: Darbepoetin alfa administered to lung cancer patients appears to be an effective, well-tolerated treatment for chemotherapy induced anemia.
