Objective To explore a safe and effective hyperthermia interventional therapy temperature for hepatic carcinoma. Methods Eight swines were divided into four groups according to trans-arterial hyperthermic perfusion temperature, 45 ?C , 50 ?C ,55 ?C , and 60 ?C (catheter flowing temperature) groups. The hepatic and renal functions and blood coagulation function were examined before and after the procedur and then all swines were sacrificed and the livers were pathologically analysed,simultoneously with the evaluation of the safe hyperthermic temperature 35 hepatic carcinomas were carried out under this interventional hyperthermochemotherapy via the arterial catheter (80 cm, 5F) placed into the tumoral artery with the perfusion agents warmed to 60~65 ?C (catheter flowing temperature was 47.55?0.44 ?C ). Results The hyperthermic coagulation necrosis, hepatic dysfunction level and fever were found after 55 ?C and 60 ?C hyperthermic perfusion while those of 45 ?C and 50 ?C groups basically remained normal. The tumor growth rate and total efficacy rate were -(0.35?0.32) and 79.2%, respectively, and 0.5, 1, 1.5 year survival rates were 100%, 80%, 60% respectively after follow-up. The adverse effects of the interventional hyperthermochemotherapy was similar to the routine TACE. Conclusions 45 ?C and 50 ?C (catheter flowing temperature) hyperthermochemotherapy for hepatic carcinoma is safe and effective.
