Comparison Between 155 Cases of Robotic vs. 150 Cases of Open Surgical Staging for Endometrial Cancer

Each year in the United States, 40,100 new cases of endometrial cancer are diagnosed. Surgery alone is often adequate for care and five-year survival rates top 96 percent for localized cancer. Laparoscopic staging has been found to be as effective as larger-incision laparotomy. A minimally invasive robotic system offers even more advantages over “open” surgery for endometrial cancer, including less blood loss, fewer perioperative complications, shorter length of operative stay, and faster return to normal activity, with the same lymph node yield.

When researchers compared data for 155 patients who underwent robotic-assisted staging by a single surgeon with 150 patients who were surgically staged via laparotomy by another surgeon, they found:

  • Blood loss—119 ml in robot group versus 185 ml in the open surgery group
  • Operative time—127 minutes in robot group versus 141 in the open group
  • Complications—10 percent in the robot group versus 27 percent in the open group
  • Cardiopulmonary complications—3.2 percent in the robot group versus 14.7 percent in the open group

The authors conclude that an experienced surgical team can reduce operative time with robotics and that robotic-assisted surgery is a “worthy alternative to laparotomy for endometrial cancer confined to the uterus.”
