title: [Expressions of key molecules affiliated cytoskeleton in laryngeal squamous cell carcinoma and their implications for prognosis].
abstract: OBJECTIVE
  To study the expressions of key assemblies of cytoskeleton, Fascin-1, Ezrin and Paxillin, in laryngeal squamous cell carcinoma (LSCC) and their correlation with clinicopathologic characteristics, cancer recurrence and survival of patients with LSCC.
  
  
  METHODS
  The expressions of Fascin-1, Ezrin and Paxillin proteins were detected by immunohistochemistry in 199 cases of LSCC. Unconditional Logistic regression model or Cox proportional hazards model was used for the analyses of recurrent risks and prognostic factors.
  
  
  RESULTS
  Significantly increased expression of Fascin-1, Ezrin or Paxillin expression was showed in the LSCC with poorly differentiated, positively cervical lymph nodal metastasis, and clinical stage III + IV respectively (P < 0.05). The expressions of three kinds of proteins in the recurrent cases were higher than those in non-recurrent cases respectively (χ(2) were 42.479, 43.673 and 22.261, P < 0.05). The highest recurrence rate (69.1%) was observed in group of cases with the highly co-expression of the three kinds of proteins (P < 0.05). The expression of Fascin-1 (OR = 7.89, 95%CI 2.26 - 27.53, P = 0.001), or Ezrin (OR = 2.51, 95%CI 1.18 - 5.32, P < 0.001) was independent risk for recurrence. Five-year disease-free survival rates of patients with high expression of Fascin-1, Ezrin or Paxillin were lower than those of patients with negative or low expressions for the proteins (P < 0.05). Patients with highly co-expression of three kinds of proteins showed the poorest survival prognosis, with a 5-year disease free survival (DFS) of only 26.4% (P < 0.05), and expressions of three proteins were independent prognostic factors for 5-year DFS (P < 0.05).
  
  
  CONCLUSIONS
  Fascin-1, Ezrin, and Paxillin were correlative with LSCC progression and might be potential predictors for cancer recurrence and survival of patients with LSCC, as well as therapeutic targets for LSCC.
