Resectability and Vascular Management of Retroperitoneal Gynecological Malignancies: A Large Single-institution Case-Series

Background/Aim: To report on morbidity and oncological outcomes in a consecutive series of gynecological malignancies involving the vascular district. Patients and Methods: We retrospectively evaluated a consecutive series between 1/2015 and 1/2017 with suspicious gynecological malignancies involving the vascular district. Peri-operative data and survival rates were computed. Results: Eight-hundred-four women with gynecological malignancies were admitted for major oncologic surgery during the study period, and among them, 50 cases (6.2%) showed vascular involvement. Twenty-seven and 23 patients were submitted to minor and major vascular procedures, respectively. R0 resection was achieved in 44 patients. There were no perioperative mortalities. Major postoperative complications occurred in 6 patients (12.0%). The 2-year disease free survival (DFS) was 67% if R0 resection was achieved. In patients with positive pathological margins (n= 2), the 2-year DFS was 33%. Conclusion: Vascular procedures can be safely performed with a proper pre-operative planning and may not be an impediment to major gynecological oncological surgery.
