BACKGROUND: Leiomyosarcoma of the inferior vena cava (IVC) is an uncommon tumor that many believe portends a poor prognosis compared with leiomyosarcoma with similar histology at other anatomic sites. Because of the limited international experience with this disease, the optimal management of these patients is unknown. METHODS: From October 1978 to January 1997, 14 patients with leiomyosarcoma of the IVC were treated at the University of California-Los Angeles Medical Center. Wide resection was attempted in all patients. The characteristics of each patient were documented and compared with those of patients with leiomyosarcoma of the stomach (n = 13), small intestine (n = 18), retroperitoneum (n = 19), and uterus (n = 10) who were treated during the same time period. RESULTS: Age, gender, tumor size, tumor grade, and lymph node status did not impact survival of patients with leiomyosarcoma of the IVC. Patients with positive surgical margins fared significantly worse (P < 0.03) compared with those who underwent complete resection. Radiation therapy diminished local recurrence and may improve median survival (6 months [n = 2] vs. 51 months [n = 12]) in this patient population. Patients who received combined chemotherapy and radiation lived longer than those who did not (P < 0.05). The 5-year cumulative survival rate (Kaplan-Meier method) was 53% for patients with leiomyosarcoma of the IVC, 47% for those with leiomyosarcoma of the stomach, 43% for those with leiomyosarcoma of the small intestine, 56% for those with leiomyosarcoma of the retroperitoneum, and 65% for those with leiomyosarcoma of the uterus. CONCLUSIONS: Despite having a tumor that originates from the IVC, patients with this tumor type can enjoy reasonably long term survival. It appears that these patients benefit from radiation therapy to control local disease. Survival of these patients is no worse than of patients with leiomyosarcomatous lesions of other origin. Aggressive surgical management combined with adjuvant therapy offers the best treatment for patients with leiomyosarcoma of the IVC.
