Interstitial Pneumonitis Related to Granulocyte Colony-Stimulating Factor Administration Following Chemotherapy for Elderly Patients with Non-Hodgkin's Lymphoma.

Abstract

We treated three cases of interstitial pneumonitis (IP) in 26 elderly (≥65 years old) patients with non-Hodgkin's lymphoma (NHL) who received the same chemotherapeutic protocol including granulocyte colony-stimulating factor (G-CSF) administration. Fortunately, all three patients recovered from IP spontaneously by discontinuation of G-CSF alone or with administration of corticosteroid. Because the duration and extent of neutrophilia induced by G-CSF administration was not different between the cases complicated by IP and those without IP, underlying pulmonary damage is suggested to be more involved than neutrophil count in the development of IP.(Internal Medicine 36: 360-364, 1997)
