简要总结
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.
详细描述
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)
- Identify the patient population for which the minimally invasive interval debulking approach will offer comparable, if not improved, outcomes as the laparotomic interval debulking technique
- Validate previously identified preoperative imaging computed tomography (CT) criteria and CA-125 values to predict optimal cytoreduction in laparotomic primary cytoreductive surgery and apply it towards the prediction of optimal cytoreduction (≤ 1 cm residual disease) following minimally invasive interval debulking surgery
- Validate the previously identified laparoscopic scoring system for primary cytoreductive surgery and apply it towards the prediction of optimal cytoreduction (≤ 1 cm residual disease) following minimally invasive interval debulking surgery
- Monitor the number of hospital days in the first 30 days postoperatively (length of stay after interval debulking including any days of readmission)
- Evaluate the oncologic safety as it relates to time to return to chemotherapy in patients who undergo laparoscopic minimally invasive interval debulking surgery
- Evaluate the complications as assessed by incidence of a composite of major complications and a second composite of minor complications

结局指标
主要结局
Proportion of patients who undergo minimally-invasive interval debulking surgery (MI-IDS) among all patients enrolled in the study
时间窗: 1 day
Feasibility measure
Percentage of patients experiencing grade 3 or 4 post-operative complications
时间窗: 30 days post-surgery
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.
次要结局
- Length of hospital stay(Up to 30 days after surgery)
- Score of Suidan preoperative predictive index parameters(1 day)
- Percentage of patients with optimal cytoreductive surgery (=< 1cm of disease seen at completion of surgery)(1 day)
- Proportion of patients who have a laparoscopy at the outset and remain laparoscopic throughout their surgery(1 day)
- Time to return to chemotherapy(30 days after surgery)
- Score of the Bristow preoperative predictive index parameters(1 day)
