The treatment of chemotherapy-induced anemia in lung cancer patients

Abstract

Anemia is common among patients with malignant tumors, due to the disease and chemotherapy. Active oncotherapy, combination chemotherapy of lung cancer is accompanied with many side effects which may impair the patient's quality of life and compromise the effectiveness of chemotherapy, the most frequent one of them being chemotherapy-induced anemia. Anemia decreases not only the patient's quality of life, but also worsens the dose-intensity of chemotherapy. One of the potential treatments of chemotherapy-induced anemia is erythropoietin-stimulating agents (ESAs) for the appropriate indications. Several national and international studies have shown that ESA therapy effectively increases hemoglobin level. However, more recently, contradictory results were published on ESA treatment in terms of survival and tumor progression. The reason for this may be that the tumor cells and endothelial cells may as well express erythropoietin receptor, the role of which has not yet been fully elucidated in tumor progression.
