title: Laparoscopic systemic retroperitoneal lymphadenectomy for women with low-risk early endometrial cancer.
abstract: BACKGROUND
  There is no consensus on the extent of lymphadenectomy and the appropriate patients for lymphadenectomy in low-risk patients with endometrial cancer. This study aimed to evaluate the feasibility and effectiveness of laparoscopic lymphadenectomy for low-risk patients with endometrial cancer.
  
  
  METHODS
  From January 2004 to May 2008, we reviewed the medical records of 28 patients with low-risk, endometrial cancer; endometrioid type, grade 1 or 2, and with a depth of myometrial invasion of less than one-half of the myometrium. All patients underwent laparoscopically-assisted staging surgery.
  
  
  RESULTS
  The median age and body mass index were 56 years (range, 28 to 75) and 25.5 kg/m(2) (range, 21.3 to 37.2). The median operating time, estimated blood loss, and length of hospital stay were 142 minutes (range, 110 to 410), 215 mL (range, 100 to 700), and 7 days (range, 3 to 19), respectively. No conversion to laparotomy was noted. The median number of harvested lymph nodes was 21 (range, 10 to 48) pelvic nodes and 12 (range, 4 to 21) para-aortic nodes. One (3.6%) patient presented pelvic lymph node metastasis and 2 (7.1%) presented isolated para-aortic lymph node metastasis. The complication rate was 14.3%. No recurrence in the vaginal vault, distant metastasis, port site metastasis was noted up to the last follow-up.
  
  
  CONCLUSIONS
  Systemic pelvic and para-aortic lymphadenectomy should be considered in all low-risk patients with endometrial cancer until it is concluded to be clinically insignificant through large-scale prospective research in the future. However, it will be difficult to explain statistical differences in survival rates according to lymphadenectomy, because the increase of the survival rate resulting from lymphadenectomy will fall within the margin of statistical error.
