title: [Value of fractional curettage of prehysterectomy in endometrial neoplasms].
abstract: OBJECTIVE
  To evaluate the value of fractional curettage in the histologic type, histologic grade and cervical involvement of the endometrial carcinoma.
  
  
  METHODS
  A total of 691 cases of endometrial carcinoma in fractional curettage specimen were analyzed retrospectively, patients with no carcinoma postoperatively in the removed uterus were excluded from the study. Those endocervical curettages with adenocarcinoma according the histologic relationship between tumor tissue and endocervical tissue were divided into 4 main groups.
  
  
  RESULTS
  (1) The inaccurate rate of histologic type in prehysterectomy curettage was 8.83% (61/691). About a half poorly differentiated adenocarcinomas were undergraded in the prehysterectomy curettage. (2) In 691 cases of endometrial carcinomas, 159 (23.01%) cases were determinated cervical involvement by tumor in the hysterectomy specimen, of which 88 cases had tumor tissue in the prehysterectomic curettage. In a variety of histologic appearances of endocervical curettage, the ratio of cervical involvement by tumor in hysterectomy was respectively group I 30.30% (10/33), group II 9 cases (9/9), group III 100.00% (40/40), group IV 46.88% (29/63), those without tumor tissue in the endocervical curettage 12.68% (71/560).
  
  
  CONCLUSIONS
  (1) The reliability of histologic type of endometrial carcinoma based on the findings of the fractional curettage specimen in related to the tumor type. The diagnosis of poorly differentiated adenocarcinomas in the prehysterectomy specimen is limited. (2) Determinating the presence or absence of cervical involvement can't only depend upon the endocervical curettage with or without tumor tissue. It is suggested that those endocervical curettage with tumor tissue be divided into 4 main groups according the histologic relationship between tumor tissue and endocervical tissue, group II and group III are good predictors of cervical involvement by tumor.
