Abstract:Objective To study the effect of immunohistochemical staining indexes of cytokeratin 5/6, P63 protein, cytokeratin 7 and thyroid transcription factor 1 in the diagnosis of non-small cell lung cancer.Methods From October 2018 to October 2020, 40 cases of bronchoscopic biopsy of lung lesions of patients with non-small cell lung cancer and 40 cases of bronchoscopic biopsy of lung lesions of patients with chronic obstructive pulmonary disease confirmed by treatment in Jiangxi Chest Hospital were selected, and 40 cases of bronchoscopic biopsy of normal lung tissue of patients were selected, which were divided into the study group 1, the study group 2 and the control group.Immunohistochemical staining was used to detect the positive expression of cytokeratin 5/6, P63 protein, cytokeratin 7 and thyroid transcription factor 1 in the three groups, and the detection results of the four indexes of cytokeratin 5/6, P63 protein,cytokeratin 7 and thyroid transcription factor 1 were compared among the three groups.Results The positive expression rates of cytokeratin 5/6, P63 protein, cytokeratin 7 and thyroid transcription factor 1 in the study group 1 were higher than those in the study group 2, the differences were statistically significant (P<0.05).The positive expression rates of cytokeratin 5/6, P63 protein, cytokeratin 7 and thyroid transcription factor 1 in the study group 2 were higher than those in the control group, the differences were statistically significant (P<0.05).Conclusion The positive expression rate of cytokeratin 5/6, P63 protein, cytokeratin 7 and thyroid transcription factor 1 in patients with non-small cell lung cancer are significantly higher than those in patients with chronic obstructive pulmonary disease and healthy people,which can be used as an important basis for screening and diagnosis of non-small cell lung cancer.
