Abstract:
Objective To explore the expression and significance of MTSS1 ( metastasis suppressor 1) in hepatocellular carcinoma.Methods MTSS1 expression was detected by immunohistochemistry in hepatocellular carcinoma, liver cirrhosis and normal liver tissues.Single-factor analysis was used to study the relationship with clinicopathological factor.Correlations between MTSS1 expression and TNM stage were analyzed with Spearman rank correlation analysis.Postoperative 5-year survival was evaluated using Kaplan-Meier survival curve analysis.Results The expression of MTSS1 in hepatocellular carcinoma was higher than normal liver tissue ( U = 168.000, P < 0.05), and liver cirrhotic tissue ( U = 106.000, P < 0.05); MTSS1 expression was correlated with TNM stage of hepatocellular carcinoma patients, lymph vascular invasion and tumor capsule ( separately U = 259.000, 258.500, 202.000, all P < 0.05).MTSS1 expression in hepatocellular carcinoma was not correlated with patients age, gender, tumor size, AFP level, and hepatitis B surface antigen.MTSS1 expression and TNM stage of liver cancer patients was negatively correlated ( rs = - 0.383 , P < 0.05 ).Postoperative 5-year survival of hepatocellular carcinoma patients with MTSS1 positive expression was significantly poorer than patients with negative and weakly positive expression (respectively 34.1% and 52.3% , x2 =6.386, P < 0.05).Conclusions MTSS1 high expression may play an important role in the early hepatocellular carcinoma progression, indicating a poor prognosis.
