Limb-salvage procedure in two patients with spindle cell carcinoma of the lower extremities using isolation perfusion

Two patients with extensive squamous cell carcinoma of the lower extremities, candidate for demolitive surgery, were treated by hyperthermic antiblastic perfusion in extracorporeal circulation. The temperature reached was 41 degrees C and the drug used was methotrexate at the dosage of 500 mg. Radical excision of the ulcer was possible in the 2 patients. Both tumors underwent extensive necrosis, and histology done 1 month after perfusion on surgical specimens showed limited areas of residual malignancy. These 2 patients suggest that hyperthermic antiblastic perfusion may be a limb salvage procedure in the multimodal management of extended squamous cell carcinoma of the extremities.
