Hyperthermic isolated limb perfusion with cisplatin in four patients with sarcomas of soft tissue and bone

The value of hyperthermic isolated limb perfusion (HILP) with cisplatin in the management of locally advanced soft tissue sarcomas or metastatic bone sarcoma was studied. Four patients were treated with HILP under mild hyperthermia (39–40°C) with 20–30 mg cisplatin/l perfused limb volume. Toxicity in the perfused limbs was moderate, and the erythema and oedema that occurred resolved spontaneously within 7–14 days as did the slight motor and sensory neuropathy over a longer period of time. Clinically, a reduction of pain was observed in all patients. Two weeks after perfusion, tumour biopsies were taken to evaluate tumour response. Two patients showed a pathological complete response, one patient showed >90% necrosis and one patient showed no response. Currently patients are treated with tumour necrosis factor and melphalan as perfusion agents. The above-mentioned results make the combination of tumour necrosis factor with cisplatin in the isolated limb perfusion setting an interesting option.
