Abstract
BACKGROUND
Soft-tissue sarcomas represent approximately 1% of adult malignancies. When they involve the lower limbs (LLs) and come into contact with blood vessels, the therapeutic choice was historically a primary amputation. Today, radical surgical resection with wide margins of safety is the primary therapeutic option for multidisciplinary limb-salvage surgery. The aim was to compare the morbidity and mortality results of an oncologic resection of LL soft-tissue sarcomas with arterial replacement (AR) to that obtained with arterial subadventitial dissection (ASD).
METHODS
All consecutive patients with arterial close contact soft-tissue sarcomas of LL were included. Two groups were formed: an AR group where AR was performed following surgical resection and an ASD group in which the artery in contact with the tumor was preserved by ASD. Fisher's exact test was used.
RESULTS
Eighteen patients with a median age of 61.50 (interquartile range [IQR] 54.25-69.75) years underwent oncovascular surgery with orthopedic and vascular surgeons between August 2013 and May 2022. Sarcomas were all located in the thigh. Nine patients were enrolled in each of the 2 groups. The 6-month survival rate was 77.78% in the AR group and 100% in the ASD group (P = 0.4). In the AR group, 2 patients presented local recurrence, with a median recurrence-free time of 24.48 (IQR 14.08-34.87) months, and 2 patients presented distant metastases, with metastasis-free time of 13.45 (IQR 8.12-35.11) months. In the ASD group, no local recurrence was observed, and 2 patients presented metastases with a median metastasis-free time of 3.90 (IQR 3.18-4.61) months. Six patients in the AR group and 7 in the ASD group required surgical revision (P = 0.017). No major amputation was necessary.
CONCLUSIONS
Oncovascular surgery for LL sarcomas with ASD is certainly more locally morbid perioperatively than that with AR but provides patients with better medium-term survival.
