Percutaneous transhepatic portography was performed in 22 patients with liver cirrhosis and portal hypertension. All patients had bled or were bleeding from presumed esophageal varices. One or more veins feeding esophageal varices were occluded with bucrylate. Follow-up examination in eight patients 1-12 months later showed recanalization of previously obliterated veins in six; however, these veins were markedly smaller than before the procedure. In patients where veins were still occluded, new veins had opened up and carried blood to the esophageal varices, which were filled to a lesser degree than before. In our experience, bucrylate is superior to Gelfoam, thrombin, and Etolein in producing venous occlusion.

Hepatocellular carcinoma was treated with slow injection of an emulsion containing 40 to 60 mg of adriamycin and 3.5 to 12 ml of Lipiodol into the portal vein via a segmental hepatic artery. During and after the injection, the portal branches of the segment were demonstrated. Six patients with resectable hepatocellular carcinoma received this treatment, which in 3 of them was followed by embolization with Gelfoam of the segmental artery. In these 3, all main tumors and daughter nodules became completely necrotic, but some infarction developed in the non-tumorous area. Those without Gelfoam had complete necrosis of all daughter nodules, but incomplete response of the main tumor. This combined treatment may be recommended for patients with localized lesions which are nonresectable due to cirrhosis, or for other reasons.

We have investigated the effects of preoperative Lipiodol-Transcatheter arterial embolization (Lp-TAE) on both the nuclear DNA content of noncancerous liver cells by DNA-cytofluorometry (using NIKON SPM-RF1-D), and the histopathological findings of liver lesions. Lp-TAE through the hepatic artery was performed on ten primary hepatocellular carcinoma patients using Gelfoam in combination with adriamycin (40 mg) or mitomycin C (20 mg), emulsified in Lipiodol (10 ml) and 60% Urografin (2 ml). And hepatic resection was carried out after one or two months later in each case. Histologically, primary hepatocellular carcinoma lesions showed various patterns of necrosis, while the non-cancerous liver cells did not show hepatocellular infarction in the liver cirrhosis. The results of the nuclear DNA content showed an increase in the fractions of poliploid cells in the non-cancerous lesions treated with Lp-TAE compared with that in the normal age-matched controls. But we found no remarkable differences in the ploidy patterns between Lp-TAE treated patients and untreated patients with liver cirrhosis. In conclusion, preoperative Lp-TAE does not induce any remarkable histological hepatocellular damage of non-cancerous lesion and does not affect nuclear DNA content of non-cancerous liver cells.

Effects of lipiodol (LPD) on liver functions were examined in 130 patients with primary and metastatic liver cancer who underwent TAE or intraarterial chemotherapy between May 1984 and March 1988 at our department and were available for follow-up studies. Effects of anticancer agents, particularly Adriamycin (ADM), were also evaluated. Large-dose intraarterial infusion of LPD had little effect on the liver functions of patients without liver cirrhosis but often caused a deterioration in liver functions of those with cirrhosis. A combination of this therapy with TAE using Gelfoam sponge caused only a temporary elevation in the transaminase level. The dose of ADM showed little association with the degree of liver disorders, unlike the case of cardiotoxicity or bone marrow suppression. Although the therapeutic effects of intraarterial infusion of ADM-LPD emulsion for advanced cancer (e.g., H4 and Vp3) such as improvements in the Vp factor are remarkable, the dose must be carefully determined, especially when liver cancer is complicated by liver cirrhosis.

Two hundred sixty-six cases of hepatocellular carcinoma (HCC) were treated between June 1980 and October 1985 (4 years and 4 months) at our hospital. Hepatectomy was performed in 118 patients, 82 of which had received transcatheter arterial embolization with iodized oil (Lipiodol) 58 of then with an intraarterial catheter. HCC tumors were often multiple when they were combined with liver cirrhosis and smaller than 3 cm in diameter. For this reason treatment of HCC by surgery alone has limitations for prolongation of life. A multidisciplinary treatment is therefore necessary. We have found hepatectomy and transarterial embolization to be the most effective treatment for HCC. In order to perform repeated embolizations after hepatectomy, we developed a heparinized catheter with notches to permit safe fixation. This is suitable for long-term intraarterial use. While previous arterial catheters only permitted infusion of drugs due to their small diameters, our new catheter can be used for embolizations with Lipiodol and Gelfoam and for angiography. It is inserted through the right gastroepiploic artery into the gastroduodenal artery so that its tip lies at the level of the hepatic artery. It is brought out through the abdominal skin and flushed at two-week intervals with heparin-urokinase. The indications for the use of the catheter have been repeated embolizations 1) for prevention of tumor recurrence (surgical adjuvant therapy), and 2) after absolutely non-curative operations. For the first indication, we have found that multiple tumors and tumors larger than 5 cm frequently recur within 1 year after surgery. We have, since July 1983, used the catheter treatment to prevent recurrence in 30 such cases. Embolization with Lipiodol + Adriamycin followed by Gelfoam cubes is performed at three-month intervals for one year after surgery, starting one month after surgery, as a rule. The preliminary results indicate an improved survival rate after the treatment.

Many patients with cirrhosis and portal hypertension demonstrate a right-to-left shunt, caused by development of anastomoses connecting the high-pressure periesophageal veins with the low-pressure bronchial and/or pulmonary veins at the level of the pulmonary hili. These anastomoses from the pathway by which small Gelfoam particles injected into the coronary or short gastric veins may embolize the systemic arterial circulation. Such embolization could have serious consequences, but reports of such complications have not been found by the authors.

Transcatheter chemoembolization, in conjunction with various drugs, has been widely used for palliative treatment of hepatocellular carcinoma. A phase II study was carried out on mitoxantrone chemoembolization. High risk cirrhotic patients were excluded from this study. Fourteen mg/m2 mitoxantrone and up to 20 ml Lipiodol were injected, followed by Gelfoam embolization as indicated. Thirty-seven patients (33 with cirrhosis) were treated. Sixty-nine cycles were delivered, with mean (+/-SD) Lipiodol and emulsified mitoxantrone doses of 11.3+/-3.8 ml and 11.8+/-5.2 mg, respectively. Thirteen, 16, and 8 patients received one, two, and three cycles, respectively, with time intervals of 123+/-60 days. Thirty patients received Gelfoam embolization at the first cycle, 9 at the second and 4 at the third. No treatment-related deaths occurred. Complications were mild and transient, including nausea/vomiting in most cases, fever over 38 degrees C 67%, pain 74%, ascites 8%, jaundice 3%, bleeding 3%, pancreatitis 3%, myelosuppression 44%, diarrhea 5%. Treatment response rate was 49% (including 16% minor responses) with 16% early progressions. With a median follow-up of 12 months, the 12-month response duration and survival rates were 56% and 79% respectively. Transcatheter chemoembolization with mitoxantrone appears to be a promising method for the palliation of advanced hepatocellular carcinoma, and deserves to be evaluated in well controlled randomized studies.

Cumulative recurrence after surgical resection for hepatocellular carcinoma (HCC) is very high. Several retrospective analyses have shown that liver transplantation was more effective than resection for patients with HCC at early tumor stages. Consequently, in January 1990, we decided to prospectively indicate orthotopic liver transplantation (OLT) as the first surgical treatment for small, localized HCC in cirrhotic patients without nodal involvement independently of the degree of liver function. The aim of this prospective cohort study was to analyze prognosis, recurrence rate, and survival after liver transplantation in patients in whom the main indication was HCC with cirrhosis. Thirty-eight patients in whom the main indication for liver transplantation was HCC and hepatic cirrhosis were compared with 136 transplantations because of cirrhosis without tumor, performed in our unit from January 1990 to December 1995. HCC arising in noncirrhotic livers and those incidently discovered after OLT were excluded from the study. Chemoembolization using doxorubicin, lipiodol, and Gelfoam was performed before OLT in 31 patients with good liver function. There were no differences in gender, but HCC patients were older (57 +/- 7 vs. 50 +/- 10 years [P < .001]). Liver function was better in HCC (Child-Pugh score: 6.9 +/- 2 vs. 8.6 +/- 1.8; P < .001), and hepatitis C virus antibody was positive in 31 (82%) vs. 51 (37%) (P < .007). Seven tumors had bilobar involvement (18%). Capsule was present in 22 (58%). The mean size of the tumor was 3.4 +/- 2 cm. Seventeen tumors (45%) were larger than 3 cm, and 4 (11%) were larger than 5 cm. The average number of nodules was 2 +/- 1. The tumor-node-metastasis stage of the tumors was pT1 in 6 patients (16%), 11 were pT2 (29%), 12 were pT3 (31%), and 9 were pT4 (24%). Seven patients were retransplanted in the HCC group (18%) and 19 (14%) in the nontumor group (not significant). Tumor recurrence was detected in three patients (8%). One, 3-, and 5-year survival rates were 82% vs. 79%, 75% vs. 71%, and 63% vs. 68%, respectively, for patients with and without HCC, and no differences were found between the two groups (P = .84). Survival was significantly reduced in patients with a macroscopic vascular invasion and tumors greater than 5 cm in diameter. Recurrence and mortality after liver transplantation in cirrhotic patients with carefully selected HCC are similar to the results in cirrhotic patients without tumor.

Transcatheter chemoembolization with various drugs is employed for palliative treatment of hepatocellular carcinoma. Thirty-seven patients (33 with Child A or B cirrhosis) were treated with 14 mg/m2 of Mitoxantrone and up to 20 ml of Lipiodol, followed by Gelfoam embolization as indicated. Sixty-nine cycles were given, with mean (+/-SD) Lipiodol and emulsified Mitoxantrone doses of 11.3 +/- 3.8 ml and 11.8 +/- 5.2 mg, respectively. Thirteen, 16, and 8 patients received one, two, and three cycles, respectively, with time intervals of 123 +/- 60 days. Thirty patients had Gelfoam embolization at the first cycle, 9 at the second and 4 at the third. At the first cycle, 10 patients underwent serial measurements of serum Mitoxantrone up to two hours after a full dose of emulsified drug. Drug levels resulted much lower than those reported after plain arterial infusion, with AUC levels (+/-SE) of 5924 +/- 1015 and 4381 +/- 429 ng/ml x 120 min in 6 and 4 cases treated with and without Gelfoam, respectively. No treatment related deaths occurred. Complications were mild and transient, including nausea vomiting in most cases, fever > 38 degrees C 67%, pain 74%, ascites 8% jaundice 3%, bleeding 3%, pancreatitis 3%, myelosuppression 44%, diarrhea 5%. Treatment response rate was 49% (including 16% minor response) with 16% early progressions. With a median follow-up of 12 months, the 12-month response duration and survival rates were 56% and 79% respectively. Transcatheter chemoembolization with Mitoxantrone deserves further evaluation in randomized studies.

There is no well-defined curative treatment for advanced and unresectable hepatocellular carcinoma. The widely used transarterial chemoembolization (TACE) with a doxorubicin-Lipiodol emulsion has not been shown to improve survival in randomized studies. Further, obstruction of the hepatic artery used in the procedure is badly tolerated in patients with cirrhosis. Drugs with a more rapid penetration into the cancer cells are likely to eliminate the need for obstruction of the hepatic artery. We therefore compared the cytotoxicity of another anthracycline pirarubicin with that of the commonly used doxorubicin. In this report, we show that pirarubicin has a greater in vitro cytotoxic effect than doxorubicin on the HepG2 and Hu-H7 human hepatoma cell lines. Pirarubicin emulsion with Lipiodol is more stable at 37 degrees C than doxorubicin-Lipiodol. Moreover, pirarubicin accumulates at a greater extent in the oil phase, permitting Lipiodol to act as a slow-releasing vector for the anthracycline. Further, amiodarone, a multidrug resistance inhibitor, was shown to decrease the intrinsic resistance of HepG2 and Hu-H7 cells to both anthracyclines, and the presence of polysorbate 80 in the amiodarone preparation increased the stability of the anthracycline-Lipiodol emulsions. We therefore conclude that pirarubicin is a better candidate for TACE than doxorubicin. The rapid and increased cytotoxicity of pirarubicin on hepatoma cancer cells and the stability of the pirarubicin-Lipiodol amiodarone emulsion could avoid the complete obstruction of the hepatic artery by Gelfoam sponges, and provide a better tolerated method of TACE in patients with latent liver insufficiency.
