title: [Association of dendritic cell infiltration with prognosis and lymph node metastasis of renal cell carcinoma].
abstract: OBJECTIVE
  To investigate the relation of dendritic cell (DC) infiltration to the prognosis and lymph node metastasis of renal cell carcinoma.
  
  
  METHODS
  The tissue specimens were obtained from 69 patients with renal cell carcinomas, who were treated surgically from 1994 to 2000 in our hospital and followed up for over 2 years. ABC immunohistochemical method using S-100 protein antibody was employed to examine the tumor tissues and the DCs was counted.
  
  
  RESULTS
  The patients showing no signs of tumor recurrence within 2 years postoperatively had significantly greater number of S-100(+) DCs in the tumor tissues than that of patients with recurrence in 2 years (61.3 +/- 14.7/mm(2) vs 31.4 +/- 11.6/mm(2)). The number of S-100(+) DCs of the group with lymph node metastasis was much lower than that of the group without the metastasis (28.8 +/- 10.4/mm(2) vs 62.6 +/- 13.5/mm(2)).
  
  
  CONCLUSIONS
  The density of DC infiltration is closely related to the prognosis and lymph node metastasis, which may be used as a good indicator for prognostic assessment of renal cell carcinoma.
