Five-year survival after retroperitoneal oncologic resection with and without vascular surgeon intervention

Abstract

Objectives Retroperitoneal tumor resection commonly disturbs major vessels; therefore, surgical teams can recruit vascular surgeons to prevent injuries and improve the prognosis of oncologic patients. The objective of the present study is to establish long-term survival after retroperitoneal tumor resection surgery with an emphasis on the potential impact of preventing or repairing major vessel injuries when tumors are adjacent to the aorta or vena cava. Methods Retrospective case series including all cases of surgical removal of retroperitoneal tumors between 2007 and 2020 in a highly specialized hospital in Mexico City. Long-term survival was defined as 5 years after surgical intervention. Descriptive statistics, group-comparison tests, and regression analysis were performed using Stata 16. Results From a total of 70 cases, vascular injury occurred in 30 (42.8%) and the vascular surgeon intervened in 19 (27.1%) of them, 4 (21%) were performed by a vascular surgeon with planned intervention, and in 9 (47.3%) cases the vascular surgeon was called to join the surgery due to emergency. Intraoperative bleeding was 2-fold greater in the group with an emergent participation of vascular surgery in contrast with the planned intervention group (4, 235 mL vs 2, 035 mL, p = 0.04). The regression model revealed a significant association between the intervention of a vascular surgeon and long-term survival (OR 59.3, p = 0.03) after adjusting for sociodemographic and characteristics of oncologic nature. Conclusions Planned intervention of vascular surgeons in retroperitoneal tumor resection may have a positive impact not only in trans-operatory period, but also on long-term survival.

Venous Reconstruction in Extremity Soft Tissue Sarcoma Is Not Essential

“…12 Importance of planned assistance of vascular surgeons was emphasized in another recent study with a positive impact on outcomes. 13 The objective of our study at this time was to update and re-evaluate the outcomes of vascular reconstructions in extremity STS based on a large group of patients from 2 tertiary centers. This study showed a high limb salvage rate of 89.4% at 24 months after surgery.…”
