title: Management and prognosis of endometrioid borderline tumors of the ovary.
abstract: BACKGROUND
  The Endometrioid Borderline ovarian tumor (EBOT) is the third most common histological subtype of borderline ovarian tumors. Very little is known about the prognosis and management of this entity. This paper consists of a review of the literature and an analysis of clinical series.
  
  
  METHODS
  A review of the literature on this topic was conducted identifying series reporting consecutive cases of EBOT using 2 search engines (MEDLINE and Pubmed). Personal data on this topic have been included and concern a series of patients treated between 1985 and 2009 for EBOT. These cases included in this series had complete data concerning patient management and follow-up > 12 months.
  
  
  RESULTS
  16 patients were studied: 7 had been treated conservatively and 9 radically. All 16/16 patients had stage I disease at the initial diagnosis but one patient had also developed synchronous endometrioid adenocarcinoma of the uterine corpus. After a median time of 24 months (range, 12-132) post treatment, one (1/16) patient had developed two recurrences. She remains disease-free 42 months after the end of treatment of the last recurrence. These data were compared to the results of 4 series previously reported in the literature. In fact, the present series reports on the first recurrence in EBOT (which was an invasive lesion).
  
  
  CONCLUSIONS
  Endometrioid borderline ovarian tumors carry a good prognosis. Most EBOT tumors are stage I, therefore surgical staging is not necessary in most of the cases. However, uterine curettage is required in cases of uterine preservation.
