title: Implementation of assisted reproductive technologies following conservative management of FIGO grade I endometrial adenocarcinoma and/or complex hyperplasia with atypia.
abstract: OBJECTIVE
  The objective was to report a series of infertility therapy outcomes following conservative management of endometrial adenocarcinoma and/or complex hyperplasia with atypia.
  
  
  METHODS
  A retrospective review of the University of Iowa assisted reproductive technology database was performed. All women presenting with International Federation of Obstetrics and Gynecology (FIGO) grade I uterine adenocarcinoma and/or complex hyperplasia with atypia were assessed for type and duration of medical management, initial, interim treatment, and preinfertility treatment endometrial biopsy (BX) findings. Assessment of infertility treatment outcomes and postinfertility endometrial biopsy findings were performed. All of the pathology samples were re-reviewed at the Gynecologic Oncology Tumor Board to confirm the diagnosis by a pathologist with a particular expertise in gynecologic pathology.
  
  
  RESULTS
  Four infertile women, three nulligravid and one primigravid, were evaluated with the diagnosis of FIGO grade 1 endometrial adenocarcinoma and/or complex hyperplasia with atypia desiring to preserve fertility. Two women with FIGO grade 1 endometrial adenocarcinoma were successfully treated with high-dose progestational agents resulting in normal proliferative endometrium. In addition, both women with complex hyperplasia with atypia were successfully treated with progestins and/or ovulation induction. Successful pregnancy outcomes were achieved for three of the four women with assisted reproductive technology. A total of five successful pregnancies and eight healthy live-born infants were achieved among three women. One of the four women was unable to conceive despite three cycles of in vitro fertilization. Hysterectomy was performed for recurrent complex hyperplasia with atypia. In our series, we found it can take 3-10 months (mean, 6.25 months; median, 6 months) to obtain benign endometrium preceding infertility therapy.
  
  
  CONCLUSIONS
  This report demonstrates that conservative management of well-differentiated endometrial adenocarcinoma and/or complex hyperplasia with atypia followed by aggressive assisted reproduction is an option to highly motivated and carefully selected women.
