title: [Surgical treatment of precancer and cancer of endometrium].
abstract: OBJECTIVE
  Our aim was to evaluate occult presence of endometrial cancer in patients with atypical glandular hiperplasia and to compare the histological prognostic factors according to the status of the lymph nodes and the grading of the occult tumour.
  
  
  METHODS
  306 patients were evaluated retrospectvely for the period of 1990-2007. They were operated one month after the hostological diagnostic atypical glandular hiperplasia obtained by D&C. All patients were with vaginal bleeding. The patients who had concomitant presence of endometrial hyperplasia and endometrial cancer were excluded from the study. One hundred patients (group A) with atypical glandular hyperplasia were compared with 206 patients (group B) without atypical glandular hyperplasia obtained by D&C. Mann and Witney test and chi-square test were used for statistical evaluation..
  
  
  RESULTS
  There was no difference between the age and the menopausal status in the two groups, only there was higher parity in group B. In group A patients with atypical glandular hyperlasia we found in 50% endometrial cancer intraoperatively, in 40% endometrial hyperplasia and in 10% normal endometrium. In the second group B were included the patients without atypical hyperplasia from D&C. In group B were found in 6% endometrial cancer in 44% endometrial hyperplasia and in 50% normal endometrium. In 30 patients was performed complete surgical staging. Six patients were with metastatic lymph nodes. All of them were with grading 2 (4 patients) and grading 3 (2 patients), and also with infiltration in the lymph-vascular spaces. Four patients were with nonendometrioid tumours (type 2 endometrial cancer).
  
  
  CONCLUSIONS
  The careful preoperative and intraoperative evaluation of the endometrium is very important in patients with atypical glandular hyperplasia. It is reasonable to use frozen section in the time of hysterectomy for patients with atypical glandular hyperplasia. If tumour with grading 2/3 nonendometrioid cancer with lymph-vascular space invasion, is found-complete surgical staging is needed.
