title: Gestational throphoblastic diseases in North East of Iran: 10 years (2001-2010) prospective epidemiological and clinicopathological study.
abstract: BACKGROUND
  Many aspects of epidemiological and clinicopathological features of gestational trophoblastic disease (GTD), one of the important subject in gynecology oncology, needs to be defined so as to recommend the best approach and management toward it. In the present study, we evaluated 10-years incidence of throphoblastic diseases in north east of Iran in prospective epidemiological and clinicopathological study.
  
  
  METHODS
  We reviewed the registered histopathology database archive (120 records) related to throphoblastic diseases of the Ghaem Hospital, Mashhad University of Medical Sciences from 2001 to 2010.
  
  
  RESULTS
  Evaluation of the pathological reports revealed 5 (4.2%) choriocarcinom and 115 (95.8%) of hydatidiform mole (HM), with complete and partial HM diagnosis in 29 (25.2%) and 86 (74.8%) patients, respectively. The pregnancy rate of HM patients (2.72 ± 1.86) and choriocarcinoma patients (3.56 ± 2.8) was not significantly different (P = 0.61). There was no statistical significant difference between the number of pregnancies in HM (2.90 ± 3.13) and choriocarcinoma (3.84 ± 3.80) patients (P = 0.46). The ratio of complete to partial mole increased with age, although this correlation was not significant. Most patients in both the groups had no history of abortion. O positive was the predominant blood group among the studied patients.
  
  
  CONCLUSIONS
  Throphoblastic diseases occur during the fertility age mostly, and there is an increased risk with more previous pregnancies; ultrasound sonography is a useful method for primary diagnosis of this disease. Further pathological studies are needed to define the mole type.
