title: Expressions of p53, proliferating cell nuclear antigen, and Ki-67 in gestational trophoblastic diseases.
abstract: OBJECTIVE
  This study was done to determine whether the expressions of p53, PCNA, and Ki-67 could differentiate spontaneous abortions with hydropic changes from gestational trophoblastic diseases.
  
  
  METHODS
  Twenty partial hydatidiform moles, 21 complete hydatidiform moles, nine invasive hydatidiform moles, three choriocarcinomas and 19 first trimester hydropic spontaneous abortions were evaluated by means of immunohistochemical methods with antibodies to p53, PCNA, and Ki-67 in this study.
  
  
  RESULTS
  The Ki-67, PCNA, and p53 immunoreactivity was significantly higher in the gestational trophoblastic disease group than in the spontaneous abortion group with hydropic changes. None of the three parameters provided reliable discrimination among gestational trophoblastic disease subgroups.
  
  
  CONCLUSIONS
  Our findings suggest that expressions of Ki-67, proliferating cell nuclear antigen and p53 can be used to differentiate between spontaneous abortion with hydropic changes and gestational trophoblastic disease when all three markers are used together.
