Multidisciplinary management and molecular characterization of inferior vena cava leiomyosarcoma: a case report.

ABSTRACT: Leiomyosarcoma of the inferior vena cava (IVC) is a rare and aggressive malignancy, with poor prognosis and no universally accepted treatment protocol. We present the case of a 69-year-old male with an IVC leiomyosarcoma, which extended from the common iliac veins to the right renal vein. Initial imaging showed a retroperitoneal mass with suspected IVC involvement. Histopathological examination confirmed leiomyosarcoma, and the patient underwent four chemotherapy cycles with doxorubicin, followed by surgical resection. A multidisciplinary approach, including general, vascular, and urologic surgeons, was employed. The tumor was excised en bloc with the IVC and right kidney. No prosthetic IVC reconstruction was necessary due to the lack of hemodynamic changes after clamping. Postoperative re
