Biomarkers of cancers are helpful in the diagnosis and treatment of patients with cancers. Biomarkers of lung cancers are rare, and thus deserve further research.Objective: The objective of the present study was to explore the expression of Fascin-1 in human lung cancer and paracarcinoma tissue, its correlation with clinicopathological characteristics in patients with lung cancer, and study the possible relationship between Fascin-1 expression and clinical–biological behavior of lung cancer.Method: This study used the MaxVision two-step immunohistochemical detection method to detect Fascin-1 expression in 84 of lung cancer and paracarcinoma tissues. This study set the expression of Fascin-1 in vascular endothelial cells as the positive control, and used phosphate buffered saline (replacing the primary antibodies) as negative control.Result: Of all the 84 lung cancer tissues and paracarcinoma tissues, positive expression of the Fascin-1 protein were detected in 78 cases (92.9%) and 27 cases (32.1%), respectively, and the difference was statistically significant (P<0.05). Differences in Fascin-1 expression between different age groups, clinical stages, and lymph node metastases were statistically significant (P<0.05), while differences in Fascin-1 expression between sexes, tumor stages, and pathological types demonstrated no statistical significance (P>0.05). The survival times of the patients with different Fascin-1 protein-positive expressions in lung cancer tissues were statistically significant (P<0.05), while the survival times of the patients with different Fascin-1 protein-positive expressions in paracarcinoma tissues were not statistically significant (P>0.05).Conclusion: In lung cancer, Fascin-1 expression was closely related to tumor invasion and metastasis, and the difference in expression of Fascin-1 had a significant effect on the survival time of the lung cancer patients. Therefore, Fascin-1 might be expected to serve as a possible potential biomarker of lung cancer. Keywords: pulmonary carcinoma, Fascin-1 protein, immunohistochemistry, survival time
