[Granulocyte macrophage-colony stimulating factor (GM-CSF) in diagnosis and monitoring of non-small cell lung cancer].
Serum tumor markers may be helpful in early diagnosis of cancer, in the initial assessment of the extent of the disease, and in monitoring the tumor growth or tumor volume reduction once cancer has been diagnosed and treatment started. Recent studies have focused on a new family of markers -hematopoietic growth factors, especially on granulocyte-macrophage colony-stimulating factor (GM-CSF). A number of investigations have shown autologous production of GM-CSF in various human cell lines derived from melanoma, gastric or ovarian cancer, and in certain tumors of nonhematopoietic origin. In this study serum level of GM-CSF was measured using a sensitive sandwich ELISA system in 34 patients with non-small cell lung cancer (NSCLC) before and 10, 30, 90, 180 and 270 days after surgical operation. Additionally common accepted tumor markers such as CEA and CYFRA 21.1 were also assayed. Preoperative level of GM-CSF was significantly increased in cancer patients relative to the normal sera (p < 0.02). Concentration of GM-CSF and CYFRA 21.1 were decreased on 10th day, but CEA on 30th day after surgical treatment, although upon comparison of pre- and postoperative tumor markers serum levels significant difference was observed for CYFRA 21.1 (p < 0.05). Levels of GM-CSF were increased in 85%, CEA in 62% and CYFRA 21.1 in 51%. The diagnostic sensitivity and serum levels of GM-CSF were related to the stage of the disease and the combined use of two markers increased the sensitivity compared with the use of only one. These results suggest that GM-CSF, especially in the combination with CYFRA 21.1., may be useful in the diagnostic and monitoring of patients with NSCLC.
