Comparing Robotics and Laparoscopy With Laparotomy/Open Surgery for Endometrial Cancer (GOC2)

This study is ongoing, but not recruiting participants.

The use of robotic surgery in the management of gynecologic cancers has increased exponentially in the United States since the implementation of technology in 2005. In Canada, access to the system is limited because of a lack of government funding. The government has been reluctant to fund this technology because robust data, on the true impact to patient care, is lacking.

This project will prospectively examine outcomes of women, with early stage endometrial cancer, treated surgically. Open surgery will be compared to minimally invasive surgery (MIS) which will include conventional laparoscopy and robotic surgery. The data collected will include detailed assessment of surgical data, peri-operative events, quality of life analysis, health economic evaluation and evaluation of MIS rates.

Cancer of the Endometrium

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: A Prospective Study Evaluating Surgical and Quality of Life Outcomes in Robotics and Laparoscopy Compared to Laparotomy in Early Stage Endometrial Cancer

Further study details as provided by University Health Network, Toronto:

Primary Outcome Measures:
  • Surgical Outcomes [ Time Frame: 6 months ]
    Intraoperative complications as well as perioperative (time to discharge from hospital), early postoperative (<4 weeks) and long-term morbidity (4 weeks to 6 months)

  • Quality of Life Outcomes [ Time Frame: 6 months ]
    Validated quality of life questionnaires to assess the time it takes a patient to return to normal activity or work, the effect of surgery on their day-to-day living, pain, body image, sexuality, social life as well as about the costs associated with their surgery.

  • Cost-effectiveness [ Time Frame: 6 months ]
    Compare cost-effectiveness between MIS (minimally invasive surgery) and open surgery for early stage endometrial cancer, by evaluating lengths of hospital stay, in hospital costs and out of hospital costs

Secondary Outcome Measures:
  • Evolution of MIS rates [ Time Frame: Prior to recruitment of the first patient and every 6 months for the duration of the study ]
    Determine the evolution of MIS rates at each centre participating in this study, including the number of surgeons offering MIS, and the number of patients offered MIS. Evaluate whether the introduction of robotic surgery increases the proportion of patients undergoing MIS. Compare the characteristics of patients undergoing robotic-assisted, laparoscopic or open surgery.

Enrollment: 550

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
New patients in the gynecologic oncology clinic will be offered the surgery that is deemed appropriate by their individual surgeon based on the patient's medical and surgical histories, type of malignancy, and the surgeon's expertise in open surgery, laparoscopy and/or robotic surgery.

Inclusion Criteria:

  • Any type of histologically confirmed early stage (stage 1 or 2) cancer of the endometrium
  • ECOG Performance status of 0-1
  • Suitable candidate for surgery
  • Signed approved informed consent
  • Female, 18 years of age or older
  • Pre-operative health is graded as ASA I-III
  • Patients able to complete baseline questions either on their own or with assistance
  • Patient willing to comply with scheduled visits

Exclusion Criteria:

  • Major abdominal surgery, chemotherapy or radiation within 3 months before the baseline visit
  • Evidence of diffuse peritoneal carcinomatosis by imaging or clinical exam
  • Unfit for surgery: concomitant disorders incompatible with the study or surgery (at the discretion of the investigator)
  • Patients who are breastfeeding or become pregnant during the study
