title: [Relationship between the reduction of FHIT expression and the development of cervical carcinoma].
abstract: OBJECTIVE
  To explore the relationship between reduction of FHIT expression of fragile histidine triad (FHIT) and the development of cervical carcinoma.
  
  
  METHODS
  Expression of the FHIT product was detected by immunohistochemistry in 22 normal cervices and 35 cervical intra-epithelial neoplasias (CINs) as well as 60 primary invasive cervical carcinomas.
  
  
  RESULTS
  The rates for loss or reduction of expression of FHIT protein in the squamous epithelium of normal cervices, CIN I-II, CIN III and noninvasive carcinoma and invasive cervical carcinoma were 0% (0/22), 20% (4/20), 53.3% (8/15), 81.7% (49/60) respectively (P<0.05). Among the well differentiated, intermediately differentiated and poorly differentiated invasive cervical carcinoma, the rates for loss or reduction of expression of FHIT protein were 60.0% (6/10), 70.0% (14/20), and 96.7% (29/30) respectively (P<0.05). The rate of the impaired FHIT protein expression in the invasive cervical carcinoma with lymph node metastasis (90.9%) was higher than that without lymph node metastasis (79.6%).
  
  
  CONCLUSIONS
  The impaired FHIT protein expression might be a useful indicator in identifying the possibility of the progression of advanced CINs into invasive cervical carcinoma. FHIT protein expression might indicate the clinical characteristic of cervical carcinoma cells and the prognosis of cervical carcinoma.
