Purpose: Fascin-1 promotes the formation of filopodia, lamellipodia, and microspikes of cell membrane after its cross-linking with F-actin, thereby enhancing the cell movement and metastasis and invasion of tumor cells. This study explored the fascin-1 protein’s expression in non-small cell lung cancer (NSCLC) tissues and its relationship with clinical pathology and prognostic indicators.
Methods: Immunohistochemical analysis was used to determine the expression of fascin-1 in NSCLC tissues. We used quantitative real-time polymerase chain reaction and western blot analysis to further verify the results. The fascin-1 expression and statistical method for clinical pathological parameters are examined by χ 2. Kaplan–Meier method is used for survival analysis. Cox’s Proportional Hazard Model was used to conduct a combined-effect analysis for each covariate.
Results: In 73 of the 128 cases, NSCLC cancer tissues (57.0%) were found with high expression of fascin-1, which was significantly higher than the adjacent tissues (35/128, 27.3%). The results suggested that the high expression of fascin-1 was significantly correlated with lymph node metastasis (=0.022) and TNM stage (=0.042). The high fascin-1 expression patients survived shorter than those NSCLC patients with low fascin-1 expression (<0.05). Univariate analysis revealed that lymph node metastasis, TNM stage, and fascin-1 expression status were correlated with the overall survival. Similarly, lymph node metastasis, TNM stage, and fascin-1 expression status were significantly associated with the overall survival in multivariate analyses by using the Cox regression model.
Conclusion: The fascin-1 protein may be a useful prognostic indicator and hopeful new target for NSCLC patients.
