Major vessel resection for complete cytoreduction in primary advanced and recurrent ovarian malignancies: A case series and systematic review of the literature - pushing the boundaries in oncovascular surgery.

Oncovascular surgery (the removal of major blood vessels infiltrated by cancer) is challenging but can be key to achieve complete cytoreduction in patient with advanced ovarian cancer. The aim of this study was to review the literature on oncovascular surgery in ovarian cancer and to report the details of all the cases performed at our institution. We retrospectively reviewed the database of ovarian cancer patients who underwent debulking surgery at the Department of Obstetrics and Gynecology of Verona University between January 2021 and 2023. Patients with at least one major vessel resection during cytoreduction were identified. We then systematically review the literature searching Pubmed and Embase from inception to January 2023 to report all cases of surgery for ovarian cancer with concomitant major vessel resection. Five patients with advanced/recurrent ovarian cancer underwent major vascular resection at our institution. Vascular involvement was preoperatively identified in all cases and no case of vascular resection was performed after accidental injury. The major vessels removed were the inferior vena cava (n = 2), the common iliac veins (n = 2), the external iliac arteries (n = 2), the left common iliac artery (n = 1), and the left external iliac vein (n = 1). All patients underwent other non-gynecological cytoreductive procedures prior to vessel removal and had R0 obtained. Three (60%) patients experienced one or more postoperative complications. The literature search identified a total of seven cases of major vessels resection in ovarian cancer surgery. A single or multiple major vessels were removed in two (28.6%) and five (72.4%) cases, respectively. All the seven patients underwent vascular reconstruction. Four (57.1%) patients reported postoperative complications. Overall, 66.7% of the 12 total identified patients were free from disease at the last follow-up [median 15.5 months (range 5-25)]. Oncovascular surgery is feasible in selected patients with ovarian cancer, provided that a multidisciplinary approach with customized care is available.
