[Noradrenaline-assisted selective chemoembolization of hepatocellular carcinoma].

Despite the postulated tumour affinity of Lipiodol is liver dysfunction after chemoembolization of hepatic malignancies common. Vasoconstricting action of noradrenaline to protect non malignant tissue was studied. 70 patients with unresectable HCCs (UICC IV: 61%) were treated via percutaneous catheter. After noradrenaline (0.1-0.8 mg) induced and documented vessel constriction a suspension of Lipiodol (5-8 ml) and Mitomycin C (10-20 mg) was injected. In addition minced dehydrated dura suspended in Lipiodol occluded the major tumour feeding vessels. 120 (73%) of a total of 164 chemoembolizations were performed after intrahepatic noradrenaline (0.1-0.8 mg) bolus injection. Arterial perfusion of non malignant liver parenchyma was significantly reduced in 95%. 24 hours later selective tumor retention of lipiodol was noticed in 67%. Side effects were fever (79%), thoracoabdominal pain (67%), nausea and emesis (43%) and tachycardia (15%). There were two treatment related deaths: one each from liver failure and cardiac arrest. By WHO response criteria there were 17 (23%) partial remissions (PR), 34 (49%) stable diseases (SD) and 20 (28%) patients had progression (PD). The median survival time from initiation of treatment was 312 days. Bilobal and multiple tumors reduced survival time (90 days). These findings suggest that noradrenaline guided chemoembolization is feasible in Europe and even in patients with pylethrombosis well tolerated.
