Is Use of SLN Biopsy for Uterine Cancer on the Rise?

Am J Obstet Gynecol; ePub 2017 Feb 14; Wright, et al

For endometrial cancer, the use of sentinel lymph node (SLN) biopsy increased from 2011-2015, especially in women who underwent a robotic-assisted hysterectomy, a recent study found. Among the 28,362 patients included in the study, 9,327 (32.9%) did not undergo nodal assessment, 17,669 (62.3%) underwent lymphadenectomy, and 1,366 (4.8%) underwent SLN biopsy. Researchers also found:

  • SLN biopsy was performed in 1.3% of abdominal hysterectomies, 3.4% of laparoscopic hysterectomies, and 7.5% of robotic-assisted hysterectomies.
  • Patients undergoing laparoscopic and robotic-assisted hysterectomy were more likely to undergo SLN biopsy when compared to abdominal hysterectomy.
  • Length of stay and cost were lower for SLN biopsy compared to lymphadenectomy in women who underwent minimally invasive hysterectomy.
