The purpose of this study is to see if patients undergoing a laparoscopic surgery for removal of ovarian, fallopian tube, or primary peritoneal cancer following neoadjuvant chemotherapy (neoadjuvant- chemotherapy given before surgery) is feasible, safe, and provides similar outcomes as compared to undergoing a large abdominal incision. Minimally invasive, or laparoscopic, surgery is a type of surgery where only small incisions are made on the abdomen and surgical instruments are placed through these incisions to perform the surgery. This type of surgery has been shown to improve outcomes in many types of surgery, including in gynecologic cancer surgery. Specifically, researchers know that patients who have minimally invasive surgery have less pain after surgery, can go home quicker from the hospital, healing time is more rapid, and potentially this can translate into returning to chemotherapy sooner. Specifically, in ovarian, fallopian tube, and primary peritoneal cancer, minimally invasive surgery has not been used as much because these cancers can have tumors all throughout the inside of the abdomen (i.e. wide tumor burden) and located in areas that are sometimes not easily reachable with laparoscopic instruments. However, the reason patients receive neoadjuvant chemotherapy is to shrink the tumor/s to make the surgery less extensive and the recovery easier. It is unknown if minimally invasive surgery can be used in this setting and by studying this, the study team will be able to determine if patient outcomes are improved by implementing (using) this surgical technique.
The objective of this study is to implement, evaluate, and further investigate the role of minimally invasive surgery in patients undergoing interval debulking following neoadjuvant chemotherapy in patients with advanced ovarian cancer.
Primary Objective:
Prospectively evaluate the feasibility and safety of the minimally invasive interval debulking approach
Secondary Objective(s)
Study Design This will be a prospective pilot study to address feasibility and safety to identify a patient population amenable to this surgical approach. This will allow for the future trial to include randomization
Exclusion Criteria:
All patients will undergo a diagnostic laparoscopic assessment of disease following neoadjuvant chemotherapy
Procedure: Diagnostic laparoscopy
The patient will initially undergo a diagnostic laparoscopy by a minimally invasive approach and entry method. The decision of which approach and entry to perform will be dictated by the primary surgeon of record's preference and their assessment of pre-operative patient factors. Once the primary surgeon determines the areas of macroscopic disease, he/she will make an assessment as to the need to convert to a laparotomy or continue laparoscopically. At the completion of the procedure, it will be noted whether an optimal cytoreduction (≤ 1 cm residual disease) or a sub-optimal cytoreduction (\>1 cm residual disease) was performed.
Proportion of patients who undergo minimally-invasive interval debulking surgery (MI-IDS) among all patients enrolled in the study
Feasibility measure
Time frame: 1 day
Percentage of patients experiencing grade 3 or 4 post-operative complications
Accordion Severity Grading system with grade 3-4 scores. Grade 3 and 4 are severe complications or death. Severe complications are those requiring endoscopic or interventional radiologic procedures or re-operation as well as complications resulting in failure of 1 or more organ system. If fewer than 14% of patients have grade 3 or 4 complications, the surgery will be deemed safe.
Time frame: 30 days post-surgery
Percentage of patients with optimal cytoreductive surgery (=< 1cm of disease seen at completion of surgery)
Rate of optimal resection after interval debulking surgery is expected to be between 73%-81%
Time frame: 1 day
Proportion of patients who have a laparoscopy at the outset and remain laparoscopic throughout their surgery
If greater than 13 of the 50 patients planned to be enrolled on the study complete the laparoscopic surgery, the study will be deemed feasible
Time frame: 1 day
Length of hospital stay
Time from the end of surgery to when the patient is discharged
Time frame: Up to 30 days after surgery
Time to return to chemotherapy
From the time of surgery to when the patient returns to chemotherapy treatments. Shorter times between surgery and chemotherapy are positive outcomes
Time frame: 30 days after surgery
Score of the Bristow preoperative predictive index parameters
23 point index where higher scores indicate poorer outcomes
Time frame: 1 day
Score of Suidan preoperative predictive index parameters
17 point index where higher scores indicate poorer outcomes
Time frame: 1 day
Plan to share: Undecided
