Abstract:
Objective To investigate the detection of monocyte chemotactic protein 1 (MCP-1),macrophage stimulating protein (MSP) and carcinoembryonic antigen (CEA) in differential diagnosis of pulmonary tuberculosis and lung cancer.Methods Thirty four patients with pulmonary tuberculosis,45 patients with pathologically confirmed lung cancer admitted in Quzhou People' s Hospital during December 2009 and December 2011,and 30 healthy controls were enrolled in the study.MCP-1 and MSP in serum and pleural effusion were determined by enzyme linked immunosorbent assay (ELISA),and CEA was detected by chemiluminescence method.Receiver operating characteristic method was used to determine the cut-off values of MCP-1,MSP and CEA in diagnosis of pulmonary tuberculosis or lung cancer.Results Serum MCP-1,MSP and CEA levels in pulmonary tuberculosis patients and lung cancer patients were higher than those in healthy controls.Compared with lung cancer patients,patients with pulmonary tuberculosis had higher serum MCP-1 and lower CEA levels (t =2.69 and 0.89,P ＜ 0.05),but there was no significant difference in serum MSP levels between two groups (t =2.89,P ＞ 0.05).While in pleural effusion,patients with pulmonary tuberculosis had higher MCP-1 level (t =3.54,P ＜ 0.05),lower MSP and CEA levels than those with lung cancer (t =3.47 and 3.48,P ＜ 0.05).Serum MCP-1 level was of the highest specificity (95.6％) with the cut-off value of 240 pg/mL in diagnosis of pulmonary tuberculosis,while MSP level in pleural effusion was of the highest specificity (94.1％) with the cut-off value of 1100 pg/mL in diagnosis of lung cancer.Conclusion Detection of MCP-1,MSP and CEA in serum and pleural effusion can be used for the differential diagnosis of pulmonary tuberculosis and lung cancer.
