The management of recurrent ovarian carcinoma is complex and depends on the time of recurrence after surgery and tumor burden. Treatment options include chemotherapy and radical cytoreductive surgery. Surgery is usually indicated in patients with good physical performance and a long interval from primary treatment. Recently, two clinical trials have suggested that secondary surgery extends survival in this setting. The results of the SOC1/SGOG-Ov2 and AGO DESKTOP III/ENGOT-ov20 clinical trials were presented at the American Society of Clinical Oncology 2020 annual meeting [
1,
2]. The gold standard approach is laparotomy for the resection of all diseases (R0). Such a complex operation may require a large incision and is associated with an increased risk of adverse events such as bleeding, blood transfusion, incisional hernia, infection, and prolonged hospital stay. Recently, roboticassisted surgery has been described by single- and multiinstitution experiences.
The first three generations of the robotic da Vinci® platform (da Vinci®, da Vinci S®, and da Vinci Si® [da Vinci® Intuitive Surgical Inc., Sunnyvale, CA, USA]) had limitations in performing abdominal and pelvic surgery because it required additional maneuvers. In 2014, the da Vinci Xi® platform (Intuitive Surgical, Inc. Sunnyvale, CA, USA) was introduced to the global market, and our practice implemented the platform in 2016. Our objective was to describe a robotic approach using the Xi platform.
A 62-year-old female with a history of stage IIC high-grade serous carcinoma of the right ovary underwent robotic-assisted radical cytoreductive surgery on December 7, 2017. Surgery included diagnostic laparoscopy, complete cytoreductive surgery (R0), radical hysterectomy, right parametrectomy, bilateral salpingo-oophorectomy, bilateral pelvic lymph node dissection, para-aortic lymph node dissection, and infracolic omentectomy. Her cancer antigen (CA)-125 level at the time of diagnosis was 51 U/mL. After surgery, the patient received six cycles of adjuvant chemotherapy with carboplatin plus paclitaxel. Genetic testing revealed a RAD51D mutation.
During surveillance, the patient’s CA-125 level ranged from 8-26 U/mL, but on April 13, 2021, it rose to 46 U/mL. A computed tomography scan showed a new mass in the right pericaval lymph node measuring 2.7×2.3 cm, which raised suspicions of recurrent disease. There were no other areas of recurrent disease (
Fig. 1). The patient was asymptomatic, with a body mass index (BMI) of 24.53 kg/m
2. Her medical history included gastroesophageal reflux disease, high cholesterol levels, and osteoarthritis. Her surgical history included prior cytoreductive surgery and left hip arthroplasty. She had a family history of breast cancer, high cholesterol, diabetes, coronary artery disease, and uterine and colon cancer. This case was presented to our multidisciplinary tumor board. The options discussed included chemotherapy and surgery.
Step 1: Diagnostic laparoscopy was performed. A 5-mm port was placed in the upper left quadrant. A systematic review of the abdomen and pelvis revealed no gross disease.
Step 2: Four robotic trocars, 8 mm in size, were placed as the following locations. The robotic camera trocar was placed in the midline and 1 cm below the umbilicus. Two trocars were placed 6 and 12 cm from the midline trocar. A fourth robotic trocar was placed in the left flank, 10 cm from the midline trocar. All robotic trocars were at the same level (Fig. 2). The Xi robot was docked in a standard fashion (left lateral docking).
Step 3: The peritoneum was incised and dissected cephalad along the aorta. The landmarks for the dissection were the following: superiorly, peritoneal reflection of the duodenum and Gerota fascia; inferiorly, the right common iliac artery; laterally, the right ureter; and medially, the aorta. The bulky tumor was sequentially dissected with a combination of blunt and sharp dissection with monopolar and bipolar cautery. The lymphatic channels and fellow veins were isolated and sealed with cautery. The specimen was removed intact in one piece, placed and secured in a 10-mm laparoscopic endobag, and removed through the infraumbilical port. Two additional para-aortic lymph nodes and cysts were removed. At the end of the procedure, no gross residual disease (R0) was observed. A fibrin sealant (10 mL) was placed along the inferior vena cava.
Step 4: The peritoneum was reapproximated using three robotic clips (Fig. 2). The estimated blood loss was 20 mL, and the operative time was 146 minutes.
The patient was admitted for observation and discharged home on postoperative day 1. Pathological assessment identified a specimen of 5.1×3.1×2.3 cm in size, with metastatic high-grade serous carcinoma consistent with the patient’s known primary.
The risk of recurrent ovarian cancer is high, and the management is complex. Recently, three clinical trials have been presented to evaluate the role of surgery. The Desktop and SOC-1 trials suggest that cytoreductive surgery plays a role in improving survival. The GOG 213 clinical trial did not find a survival advantage of surgery when compared to chemotherapy [
3]. Laparoscopy and robotic-assisted surgery have been introduced in many institutions as an alternative to open surgery for secondary cytoreductive surgery, but published data are limited [
4-
8]. The National Comprehensive Cancer Network guidelines suggest that minimally invasive techniques can be used for selected patients for interval debulking procedures. Patients who are unwilling to be optimally debulked using minimally invasive techniques should be converted to open procedures [
9].
The advantages of the da Vinci Xi® (Intuitive Surgical Inc.) are its versatility for multi-quadrant surgery with very simple maneuvers, thinner arms, increased range of motion, and same-size trocars that enable camera placement in any port. The Xi platform allows the surgeon to perform pelvic surgery and then move to upper abdominal surgery by rotating the pivot boom without changing the patient cart location.
With simple and reproducible steps, our video showed the feasibility and safety of robot-assisted surgery with the benefits of low blood loss, low levels of surgical pain, and short hospital stays. Features of the ideal candidate for consideration for robotic-assisted surgery for recurrent ovarian cancer may include the presence of an isolated tumor, absence of ascites and carcinomatosis, adequate exposure, and access to the tumor. A standard open approach should be reserved for patients with extensive adhesions and multiple sites of recurrence. Since there is no prospective or randomized trial that compared open surgery to robotic-assisted surgery, a tumor registry or more publications are needed to confirm the safety of the procedure. A longer follow-up period of survival is also warranted. Robotic-assisted surgery is safe and feasible for selected patients with isolated recurrent ovarian cancer or for laparotomy in selected patients.
