Abstract

Granulopoiesis at the diagnosis of solid tumors has not been previously reported. The purpose of this study is to detect the changes of granulopoiesis of patients with solid tumors in different clinical stages. Granulocyte-macrophage colony-forming unit (CFU-GM) assays and liquid suspension cultures of bone marrow and peripheral blood were studied in 90 children with newly diagnosed solid tumors, including 5 benign tumors and 85 malignant tumors. The malignant tumors were categorized into nonadvanced, advanced, or marrow-invaded ones. Bone marrow from children with immune thrombocytopenic purpura and peripheral blood from adult volunteers were used as controls. Granulocyte-macrophage colony formation from bone marrow in benign or nonadvanced malignant tumor was not significantly different from that of controls. However, granulocyte-macrophage colony formation from bone marrow in advanced or marrow-invaded malignant tumor was significantly less than that of controls or nonadvanced malignant tumor. Furthermore, the bone marrow of patients with advanced malignant tumor occasionally had a defective proliferation pattern and the bone marrow of those with marrow-invaded malignant tumor often had a defective proliferation pattern. Peripheral blood in marrow-invaded malignant tumor had colony and cluster formations in very wide ranges. As a malignant tumor progresses into advanced stages, irrespective of marrow infiltration, bone marrow CFU-GM levels may decline and defective granulopoiesis may occur.
