A review by researchers from Hôpital Sud, Rennes, France, and McGill University, Montreal showed that surgery by robot—rather than traditional open surgery—may improve outcomes in elderly patients with pelvic cancer, however the research is sparse. For instance, only 6 published studies specifically address surgery in the elderly with endometrial cancer, the most common gynecologic malignancy in the western world. However, because surgery is challenging for these often-frail patients, minimally invasive (or minimal access) surgery could be the answer. When comparing robotics to standard laparoscopy in treating endometrial cancer, the data suggest significantly less blood loss, reduced operative time, and higher node counts.

Similar to many others, the researchers’ academic center was slow to adopt minimally invasive standard (MIS) laparoscopy. But within 2 years of the introduction of robotic surgery in 2007, more than 95% of patients requiring surgery to treat endometrial cancer undergo MIS. Now, the surgery is offered to each operable patient unless the cancer cannot be extracted intact or in a 15-cm diameter endobag via the vagina.

The researchers note that the MIS procedure has some unique risks. For example, once the patient is “docked” to the robot, the Trendelenburg position can’t be reversed without undocking. This may adversely affect the respiratory and cardiovascular system. Despite case reports about such adverse effects, though, the researchers say most data support the safety of robotic surgery in the elderly. Moreover, the newest versions of robots allow for multiple quadrant access without the need to undock.

The oncologic safety of robotic surgery seems similar to that of open surgery or laparoscopic surgery. After 2 years of follow-up in 1 study, rates of progression-free survival were similar for the different methods. The researchers advise surgeons to work toward improving preoperative frailty assessments that will help tailor the right surgery for the right subgroup of elderly patients.
