Primary venous leiomyosarcoma: a rare but lethal disease

Area of Science:

• Vascular Surgery
• Surgical Oncology
• Rare Cancers

Background:

• Primary venous leiomyosarcoma is exceptionally rare, with limited reported cases.
• Understanding diagnosis, treatment, and outcomes is crucial for improving patient survival.
• This study reviews institutional experience with this rare malignancy.

Purpose of the Study:

• To analyze the diagnostic methods, surgical treatments, and clinical outcomes of primary venous leiomyosarcoma.
• To identify factors influencing survival and recurrence in patients with venous leiomyosarcoma.
• To evaluate the effectiveness of surgical interventions for venous leiomyosarcoma.

Main Methods:

• Retrospective review of 13 patients treated for primary venous leiomyosarcoma over 35 years.
• Analysis of surgical procedures, including local excision and venous reconstruction.
• Evaluation of tumor characteristics, perioperative mortality, and long-term survival data.

Main Results:

• The study included 13 patients (12 female, 1 male; mean age 55 years).
• Tumors originated from the inferior vena cava, iliac, ovarian, or greater saphenous veins.
• Perioperative mortality was 15%; median survival for early survivors was 3.5 years, with 5 patients currently alive (4 tumor-free).
• Recurrence was observed in 6 of 8 deceased patients, unaffected by tumor grade, size, or adjuvant therapy.

Conclusions:

• Wide local excision with selective venous reconstruction is the primary treatment for prolonged survival.
• Early detection through advanced imaging may improve outcomes.
• Despite aggressive treatment, venous leiomyosarcoma has a significant recurrence rate and challenging prognosis.
