ABSTRACT
Objective@#To investigate the expression of fragile-site associated tumor suppressor (FATS) in non-small cell lung cancer and its relationship with clinicopathological features and prognosis.@*Methods@#A total of 140 non-small cell lung cancer (NSCLC) cases and 30 adjacent normal tissues were used to detect the expression level of FATS protein, and to analyze the relationship of FATS protein expression and clinicopathological features and prognosis of NSCLC.@*Results@#Western blot showed that the expression of FATS in adjacent normal tissues was significantly higher than that in non-small cell lung cancer tissues. The results of immunohistochemistry showed that the high expression rate of FATS in 140 cases of NSCLC was 40.0%, and the high expression rate of FATS in 30 cases of adjacent tissues was 73.3%. The difference was statistically significant (P=0.01). Further analysis showed that the TNM stage (P=0.044) and lymph node metastasis (P=0.022) were significant difference between FATS high expression group and low expression group. The 6-year overall survival (OS) rates of NSCLC patients with FATS high-expression and low-expression were 57.1% and 23.8%, respectively, and the 6-year disease-free survival (DFS) rates were 53.6% and 21.4%, respectively, with statistically significant differences (P=0.001). In Cox multivariate analysis, we found gender (HR=1.658, P=0.028; HR=1.684, P=0.023), TNM staging (HR=2.327, P=0.019; HR=2.332, P=0.013) and FATS expression (HR=0.532, P=0.010; HR=0.538, P=0.009) were independent prognostic factors for both OS and DFS of NSCLC patients.@*Conclusions@#The expression of FATS protein is associated with the development and is an independent prognostic factor of NSCLC patients. The detection of FATS protein is expected to be a new biomarker for evaluating the prognosis of NSCLC patients.
