title: [Tumor infiltrating dendritic cells and Mucin1 gene expression in benign prostatic hyperplasia and prostate cancer].
abstract: OBJECTIVE
  To study the expression of Mucin1 gene and tumor infiltrating dendritic cells(TIDC) in the tissues of benign prostatic hyperplasia (BPH) and prostate cancer.
  
  
  METHODS
  Mucin1 and TIDC were detected in 20 specimens of BPH and 30 specimens of prostate cancer by immunohistochemistry SP method.
  
  
  RESULTS
  MUC1 expressed in both prostate cancer and BPH. The staining patterns were significantly associated with tumor pathological grade (P < 0.001). The number of TIDC was negatively correlated with tumor pathological grade, the higher the grade, the smaller the number of TIDC (P < 0.001).
  
  
  CONCLUSIONS
  The expression pattern of MUC1 and the number of TIDC could be considered as useful markers to evaluate the malignant degree and prognosis of prostate cancer. The decrease of TIDC plays an important role in tumor immune evasion and immune tolerance. Highly expressed MUC1 could lead to the failure of hormonal treatment for prostate cancer, and contribute much to tumor infiltration and metastasis.
