Liposarcoma of the leg

Area of Science:

• Surgical Oncology
• Orthopedic Oncology
• Medical Physics

Background:

• Liposarcomas of the leg are malignant soft tissue tumors requiring effective treatment strategies.
• Traditional surgical approaches include wide local excision and amputation, each with limitations.
• The efficacy of regional hyperthermic perfusion in managing extremity liposarcomas remains an area of investigation.

Purpose of the Study:

• To compare the effectiveness of three treatment modalities for leg liposarcomas: wide local excision, amputation, and regional hyperthermic perfusion.
• To evaluate the impact of each treatment on local recurrence rates and distant metastasis.
• To assess the potential for limb salvage and functional preservation with these interventions.

Main Methods:

• Retrospective review of 48 patients diagnosed with liposarcomas of the leg.
• Patients were categorized based on treatment received: wide local excision, amputation, or regional hyperthermic perfusion.
• Analysis of local recurrence rates, distant metastasis, and limb salvage outcomes.

Main Results:

• Distant metastasis rates were comparable across all treatment groups.
• Local recurrence rates were 43% for wide local excision and 29% for amputation.
• No local recurrences were observed in patients treated with regional hyperthermic perfusion.

Conclusions:

• Regional hyperthermic perfusion combined with excision demonstrates superior efficacy in preventing local recurrence of leg liposarcomas.
• This combined approach offers a significant advantage over wide excision or amputation alone.
• Hyperthermic regional perfusion facilitates limb salvage while achieving excellent local tumor control.
