title: Surgical stage, final grade, and survival of women with endometrial carcinoma whose preoperative endometrial biopsy shows well-differentiated tumors.
abstract: OBJECTIVE
  The purpose of our study was to assess the surgical stage, final grade, and survival of women with endometrial carcinoma whose preoperative endometrial biopsy showed well-differentiated (FIGO grade 1) carcinoma.
  
  
  METHODS
  A retrospective study was conducted including all women treated at the University of Vermont between 1992 and 2004 whose preoperative endometrial biopsy was reviewed by the staff at the Pathology Department and diagnosed as FIGO grade 1 adenocarcinoma and who received peritoneal washings, total abdominal (or laparoscopic) hysterectomy, bilateral salpingo-oophorectomy, and pelvic +/- para-aortic lymphadenectomy as part of their surgery.
  
  
  RESULTS
  One hundred eighty-two patients (age: 32-91, median: 60) were enrolled. All patients had total hysterectomy, bilateral salpingo-oophorectomy, peritoneal washings, and bilateral pelvic lymphadenectomy. Fifteen (8.2%) patients had para-aortic lymphadenectomy. There were no operative mortalities. Fourteen patients (7.7%) had major operative or postoperative complications. There was disagreement between the pre- and postoperative grade in 30% of the study group. The surgical stages were: IA: 55 (30.2%), IB: 61 (33.5%), IC: 26 (14.3%), IIA: 9 (4.9%), IIB: 8 (4.4%), IIIA: 10 (5.5%), IIIB: 2 (1.1%), IIIC: 8 (4.4%), and IV: 3 (1.6%). Postoperatively, 131 (72%) patients received no additional treatment, 47 (25.8%) received radiation therapy, 3 (1.6%) received chemotherapy, and 1 (0.5%) received Megace. During a median follow-up period of 6 years, 8 (4.4%) patients had recurrence and 6 (3.2%) died from their disease. The 5-year disease-free and overall survival was 95.2% and 96.4%, respectively.
  
  
  CONCLUSIONS
  Approximately 30% of women with endometrial carcinoma whose preoperative endometrial biopsy shows grade 1 tumors have grade 2 or 3 in the hysterectomy specimen and 12.6% have advanced surgical stage (stage III and IV) disease. Women with preoperative endometrial biopsy showing grade 1 tumors who undergo surgical staging have excellent survival and acceptable operative morbidity.
