title: [Dendritic cell infiltration in lung adenocarcinoma and its effect on prognosis].
abstract: OBJECTIVE
  To study the infiltration degree of dendritic cells in lung adenocarcinoma and its effect on prognosis.
  
  
  METHODS
  S-100 protein was used as the specific marker for dendritic cells, and immunohistochemistry was employed to detect the distribution of dendritic cells in lung adenocarcinoma.
  
  
  RESULTS
  Among 46 cases of lung adenocarcinoma, 19 were markedly infiltrated by dendritic cells, the five-year survival rate being 61%; 27 showed slight infiltration, the five-year survival rate being 21%. Among the 46 cases of adenocarcinoma, 26 were low differentiated adenocarcinoma, in which 10 were infiltrated markedly by dendritic cells, five-year survival rate being 57%; and 16 were slightly infiltrated, five-year survival rate being 16%. These data were evaluated with the log-rank test, which showed a significant difference between the markedly infiltrated group and the slightly infiltrated group.
  
  
  CONCLUSIONS
  The prognosis of lung adenocarcinoma which markedly infiltrated by dendritic cells is better than that of slightly infiltrated by dendritic cells.
