Leiomyosarcoma of the Inferior Vena Cava-experience of 2 Cases

ABSTRACT

Leiomyosarcoma of the inferior vena cava (IVC) is a rare malignant tumor originating in the smooth muscle of the media. Though only two hundred and eighteen cases have been reported in International Registry until 1994, it is the most common malignancy of the IVC. Various treatment including adjuvant chemotherapy has been advocated but controversy exists due to lack of a large series and of a long-term follow-up of the published cases. Radical resection with negative margins remains the only hope for cure. Two cases of well documented IVC leiomyosarcoma surgically treated at Asan medical Center are reported.
