BACKGROUND: Between 1990 and 1999, we performed radio-hyperthermo-chemotherapy (RHC) in 44 patients with high-grade soft-tissue sarcomas of the limbs.
METHODS: Radiotherapy involved the delivery of radiation at a dose of 2 Gy once daily on 16 days, to give a total dose of 32 Gy. Hyperthermia was conducted once a week, with a total of five sessions. Chemotherapy was performed by implanting a reservoir and administering cisplatin (3 mg/kg) three times, and pinorubin (an adriamycin derivative; 1 mg/kg) twice by intra-arterial infusion, at weekly intervals. These drugs were administered alternately during hyperthermia sessions.
RESULTS: Tumor shrinkage was observed in 98% (43/44) of the patients. Of the 36 patients with M0 tumors, 30 were disease-free at final follow-up, 2 had no evidence of disease, 1 was alive with disease, and 3 had died of the disease. Amputation was required only in the first patient, and the affected limb was preserved in the other 43 patients. The surgical margin was wide in 9 patients and marginal in 29 patients, and intralesional excision was performed in 5 patients. There was recurrence in only 1 of the 44 patients.
CONCLUSION: RHC is currently the most potent and relatively safe treatment method for high-grade soft-tissue sarcomas that is available clinically.
