title: Platelet-derived endothelial cell growth factor as a prognostic factor for radiotherapy outcome in patients with adenocarcinoma of the uterine cervix.
abstract: OBJECTIVE
  The aim of this study was to evaluate the platelet-derived endothelial cell growth factor (PD-ECGF) and VEGF expressions of tumor cells as prognostic factors for radiotherapy outcome in patients with adenocarcinoma of the uterine cervix.
  
  
  METHODS
  In 47 formalin fixed, paraffin-embedded tissues from adenocarcinoma of the uterine cervix which had been treated with radiation (1970-1995), PD-ECGF and VEGF expressions were determined using immunohistochemistry, and the relationships between PD-ECGF or VEGF expressions and local control or survival were assessed.
  
  
  RESULTS
  PD-ECGF and VEGF expressions were successfully detected in the cytoplasm and/or nucleus of adenocarcinoma cells of the uterine cervix. Of the 47 patients, 44.6 (21/47 cases) and 57.4% (27/47 cases) were positive for PD-ECGF and VEGF, respectively. There was no correlation between PD-ECGF or VEGF expressions and age, grade, or histologic subtypes. Stage and high expression of PD-ECGF showed a significant correlation to local control (P = 0.0025, P = 0.0057, respectively) and were significant independent prognostic factors for 5-year survival in multivariate analysis (P = 0.0039, P = 0.0032, respectively).
  
  
  CONCLUSIONS
  This study demonstrated that PD-ECGF expression was a significant prognostic factor for radiotherapy outcome in patients with adenocarcinoma of the uterine cervix. Preradiation assessment of PD-ECGF expression may be helpful in selecting high-risk patients, providing them with opportunities to receive more sophisticated and individualized treatments.
