Neoadjuvant Hypertermic Isolated Limb Perfusion in Treatment of Undifferentiated Spindle Cell Sarcoma of Lower Limb with Achieved Complete Pathologic Response


Klin Onkol 2019; 32(3): 211-213. DOI: 10.14735/amko2019211.

Background: Hyperthermic isolated limb perfusion uses therapeutic effect of hyperthermia in the bounded compartment of the limb together with increased concentration of chemotherapy effect than what would be achieved in systemic application. Gold standard was melphalan (Alkeran) in combination with tasonermin (Beromun, tumor necrosis factor alpha). The efficacy of this combination has been demonstrated in limb soft tissue sarcomas and in patients with limb isolated bulky disease of malignant melanoma. Case: We describe a case of a 65-year-old female patient with undifferentiated spindle-cell sarcoma treated by a multidisciplinary team at the 2nd Surgical Clinic of Cardiovascular Surgery and Clinic of Oncology General University Hospital in Prague and at the Department of Orthopaedics Na Bulovce Hospital with the aim of preserving the limb despite the advanced disease. The patient underwent hyperthermic isolated limb perfusion with tasonermin and melphalan with partial response on magnetic resonance imaging. Subsequent wide resection was done with complete pathological remission according to histological examination maintaining a fully functional limb. The patient is followed without signs of recurrence. Conclusion: Hyperthermic isolated limb perfusion with tasonermin and melphalan is an important part of a multimodal approach in the treatment of extremity sarcomas with a high percentage of responses that increase the percentage of limbs retaining resections. Multidisciplinary team should consider this option in patients with localized limb sarcomas and should be performed in specialized centers with experience in this procedure.
