Imaging classification and surgical strategy of retroperitoneal vascular leiomyosarcoma: experience from a single medical center.

ABSTRACT:

Background

Retroperitoneal vascular leiomyosarcoma (RVLMS), which originates from vascular wall smooth muscle cells, typically requires inferior vena cava (IVC) reconstruction during radical surgery.

Methods

A retrospective cohort study was conducted on 24 patients who underwent primary resection of RVLMS from June 2015 to November 2023 in one institution. The patient details, operative management, and follow-up data were assessed.

Results

Regarding the imaging classification of RVLMS, 6 patients were intraluminal type, 9 patients were intermediate type, 4 patients were extraluminal type, and 5 patients were peripheral type. The median tumor size was 80 mm (interquartile range, IQR 63-105 mm). The median operative time was 294 min. The median blood loss was 650 ml. Th
