Abstract
From January 1986 to December 1988, 85 patients (55 men and 30 women, mean age 59 years) with metastatic liver tumors were treated with hepatic artery embolization (TAE) or infusion (HAI). Sixty-eight patients with successful catheterization were treated with TAE using iodized oil (Lipiodol) mixed with anticancer agent (ACA). In 12 of 68 patients with hypervascular tumors gelatin sponge was added. Patients with unsuccessful catheterization were treated with hepatic artery infusion of ACA. Forty-three patients received oral chemotherapy following TAE or HAI. Overall, the 6-month, and 1- and 2-year survival rates were 69.5, 31.8 and 4.1 per cent, respectively (mean 233 days). A univariate analysis of prognostic factors showed that number of metastases, stage, treatment times and oral chemotherapy were all significant factors (p<0.05). Ascites, jaundice, percentage of hepatic replacement and treatment protocol also had some influence (p<0.1). Sex, age, primary site, elevation of tumor markers, other metastatic lesions, portal vein involvement and difference in anticancer agent had no prognostic significance. A multivariate analysis using Cox's proportional hazard model revealed that the number of treatments had the most important prognostic significance, followed by oral chemotherapy, stage and percentage of hepatic replacement.

Abstract
Computed tomography (CT) was performed in 54 patients with hepatocellular carcinoma three weeks after transcatheter arterial chemotherapy using iodized oil and doxorubicin with or without gelfoam embolization. Patients with iodized oil retention in the tumor greater than 50 per cent of tumor size survived longer than patients with retention of less than 50 per cent. Differences were also found within Okuda stages I and II, but they were significant only in Okuda stage I (p<0.0001). These results suggest a possible relationship between iodized oil retention and survival. In addition to Okuda stage, several factors affected iodized oil retention: tumor vascularity, tumor size, portal thrombosis and Gelfoam embolization. These factors may thus influence the prognosis after transcatheter arterial chemotherapy.

Abstract
Sixty-one patients with liver metastases were treated with hepatic arterial injection of Adriamycin/Mitomycin C oil suspension (ADMOS). The liver metastases originated from the gastrointestinal tract in 41 patients and from other organs in 20 patients. Sixty-nine liver tumors were analyzed in these 61 patients. Computed tomography (CT) after ADMOS injection (Lip-CT) gave more information in 19 cases (31%) than enhanced CT with a water-soluble contrast medium. With Lip-CT, Lipiodol tumor enhancement was observed in 64 of 69 lesions. The patterns of Lipiodol uptake in the tumors were classified into 4 types: Homogeneous accumulation (20%), heterogeneous accumulation (16%); accumulation with a central defect (57%); and no accumulation (7%). A tumor response was achieved in 41 of 69 lesions (59%). Anticancer effects were also shown as a decrease in serum CEA levels. The one year survival rate estimated by the Kaplan-Meier method was 43 per cent and the median survival time was 337 days. The results were better among patients who received multiple doses of ADMOS. Only minimal side effects were associated with ADMOS. The method is considered to be an excellent diagnostic and therapeutic procedure for liver metastases.

Abstract
Since two decades transarterial chemoembolization (TACE) of liver metastases has been investigated in numerous studies. However, no standardized therapeutic procedure exists so far. The present study retrospectively investigated survival, response and side effects after TACE of liver metastases in 21 patients with colorectal cancer and results are compared with previous literature. A total of 68 TACE procedures were performed. A suspension of degradable starch microspheres (DSM, Spherex) and Mitomycin C was applied selectively into hepatic arteries via a transfemoral approach. DSM effect a temporary arterial occlusion. Follow-up studies were performed by contrast enhanced spiral computed tomography (CT). The median survival was 13.8 months. Therapeutic response (according to WHO) was observed only in three patients. The progression free interval was 5.8 months. Patients developed a postembolization-syndrome (abdominal pain, fever, nausea) and increased transaminases in 27-43% of all interventions. A gastric ulcer occurred after four, cholecystitis after two TACE. As already shown in most previous studies, regardless of the used agents, also this investigation underlines the moderate therapeutic effect of TACE on colorectal liver metastases. So far, no significant survival benefit has been shown in the literature and the response rates are rather limited. In general, complications of TACE seem to be rare, but should not to be underestimated. Compared to TACE with long or permanent arterial occlusion, postembolization syndrome seems to be less pronounced using DSM. As TACE is rather a palliative therapeutic approach, DSM therefore might be more suited. Further studies on TACE of liver metastases should focus on to the patients' quality of life.

Abstract
Computed tomography fluoroscopy (CTF) allows real-time display (continuous imaging) and has been increasingly used in interventional procedures. We wished to demonstrate the usefulness of CTF in chemoembolization of the liver. Twenty-one patients with primary or secondary malignant lesions of the liver underwent CTF-guided chemoembolization after angiographic positioning of a catheter in the hepatic artery. Embolization materials such as Lipiodol and mitomycin C were administered under continuous CT scanning. CTF led to a change of the method (correction of catheter position, application of norepinephrine) in nine of 21 cases. There were no fatal complications.

Abstract
BACKGROUND Hepatic artery chemoembolization represents an alternative treatment for patients whose neoplastic lesions are not amenable or have become refractory to other treatment modalities. This project was designed to test the feasibility of regional chemoembolization for patients with colorectal carcinoma metastasis to the liver who had experienced failure with one or more systemic treatments. METHODS Thirty patients who met the study entry criteria underwent one to three hepatic artery chemoembolizations. The chemoembolization regimen consisted of an injection of a bovine collagen material with cisplatin (10 mg/mL), doxorubicin (3 mg/mL), and mitomycin C (3 mg/mL). Repeat treatments were performed at 6- to 8-week intervals. RESULTS Radiologic responses, as measured by a decrease in lesion density of at least 75% of the lesion or a 25% decrease in the size of the lesion, occurred in 63% of the cases. A decrease of at least 25% of the baseline carcinoembryonic antigen level occurred in 95% of the cases. All responses were transient. Median survival for all 30 patients was 8.6 months after the initiation of chemoembolization and 29 months after the initial diagnosis of metastasis to the liver. Common toxicities included a "postembolization syndrome," which consisted of fever > 101 degrees F (83%), pain in the right upper quadrant (100%), nausea, and vomiting. Lethargy was a common occurrence (in 60+% of cases) and lasted up to 6 weeks. Hematologic toxicities included leukocytosis, anemia, and thrombocytopenia. CONCLUSIONS Chemoembolization is a feasible treatment modality for patients with colorectal carcinoma metastasis to the liver who have experienced failure with other systemic treatments. It results in high response rates with transient mild-to-moderate toxicity. Responses are measured in months, however, and all patients have eventual progression of disease. Patients who are able to undergo three or more chemoembolization procedures may receive the most clinical benefit.

Abstract
The purpose of this study was to analyse the biodistribution of rhenium-188 Lipiodol in rats with hepatic tumours following intrahepatic arterial injection to assess the potential of 188Re-Lipiodol as a radiopharmaceutical for the treatment of hepatic tumours in humans. Twelve male rats with hepatic tumours were killed at 1h, 24h and 48h after injection of approximately 7.4MBq of 188Re-Lipiodol via the hepatic artery. Samples of various organs were obtained and counted to calculate the tissue concentration. Radioactivity in the hepatic tumours was very high throughout this study, with a biological half-life of 122.9h. Radioactivity in the normal liver tissue was also high, but was significantly lower than in the tumour. The biological half-life in the normal liver tissue was 31.7h. The ratio of tumour concentration to the normal liver tissue concentration was 5.15 at 1h and rose to 7.7 at 24h and 10.84 at 48h. The level of radioactivity in the lung was high at 1h, and declined rapidly over time. The level of radioactivity in the kidney was moderate throughout the study. The radiation concentrations in muscle, spleen, testis, bone and whole blood were insignificant. We conclude that 188Re-Lipiodol should be considered as a potential radiopharmaceutical for the intra-arterial treatment of hepatic tumours.

Abstract
Meningiomas rarely give rise to metastases despite frequent dural invasion. A rare case of symptomatic hypoglycaemia due to extensive liver metastases from an angioblastic meningioma is described along with the use of hepatic arterial chemo-embolization to effect palliation by reduction in tumour bulk.

Abstract
When injected into the hepatic artery the contrast agent Lipiodol (iodized poppy seed oil) is selectively retained by hepatocellular carcinoma (HCC) for a prolonged period of time. Liver computed tomography (CT) performed after Lipiodol angiography is more sensitive than ordinary CT at imaging HCC. Arterial administration of cytotoxic drugs and radioisotopes conjugated to Lipiodol has been shown to be reasonably safe in patients with irresectable HCC. These therapies, often combined with embolization, provide effective palliation, better tumour response and improved survival compared with other available treatments. Their use as a preoperative adjunct to surgical resection of HCC is controversial.

Abstract
Thirteen patients undergoing selective coeliac angiography before insertion of an indwelling hepatic arterial cannula underwent injection of 3 ml radiolabelled Lipiodol (2 MBq 131I) into the hepatic artery at the end of the procedure. At subsequent laparotomy 1-9 days later, biopsies were taken from normal liver and metastases. The radioactivity of this material was measured to establish the tumour:liver ratios. Two patients with large metastases (> 10 cm in diameter) had low ratios. In the remainder, the median ratio at 24 h was 1.5:1 (range 1.1-2.5:1; n = 5) and 2.6:1 (range 1.5-64.0:1; n = 6) at 3-9 days. Four patients underwent single photon emission computed tomography, which confirmed selective retention of Lipiodol in small metastases, although no activity was detected in a large deposit (> 15 cm) 10 days after injection. The tumour:liver ratio in the other three patients increased from 3.0-5.6:1 on day 1 to 4.5-7.2:1 on day 6. This study suggests that Lipiodol may be a useful therapeutic delivery agent to small colorectal liver metastases.

Abstract
From January 1987 to December 1989, we performed a prospective study of transcatheter arterial chemoembolization therapy with iodized oil (Lipiodol) mixed with an anticancer agent. A new oil-soluble modification of FUdR, FUdR-C8 ester, was developed and dissolved in Lipiodol as an embolic material, which was administered to 36 patients with hepatomas. Water-soluble adriamycin emulsified in Lipiodol was used as control in 67 patients with hepatomas. Initial effects on tumors were observed as decrease of tumor size in 25.0% for the FUdR group and 17.9% for the control group. Alpha-fetoprotein decreased more than half in 41.9% of the FUdR group, and 16.1% of the ADM group. Six-month and one-year survivals were 74.2% and 46.8% for the FUdR group (median survival 317 days), whereas the control group yielded 61.0% and 28.3% survivals, respectively (median survival 191 days).

Abstract
Liver tumours frequently present at a late stage and only a minority of patients are likely to benefit from resection or transplantation. Inoperable tumours carry a grave prognosis. External beam irradiation of the liver is dose-limited by the radiosensitivity of hepatocytes, particularly in the presence of cirrhosis, but internal radiation using radio-isotope sources can achieve more selective irradiation of the chosen field. Sealed sources are dose-limited by their effects on surrounding tissues, whereas with unsealed sources the dose of radio-isotope administered is limited by bone marrow suppression. Iridium-192 wires are most frequently employed as a sealed intracavitary source. They may be inserted surgically, transhepatically or endoscopically. Doses of up to 60 Gy can be delivered to a malignant biliary stricture without damage to the surrounding parenchyma. The incidence of cholangitis is low if treatment is administered after insertion of an endoprosthesis. Unsealed radio-isotope sources may be injected directly into the tumour, administered embolically via the hepatic artery in the form of microspheres or lipid droplets, or given via parenteral infusion attached to tumour-specific antibodies. Of these vehicles, the lipid agent Lipiodol appears to be the most effective and can deliver a potentially lethal dose of radiation to small tumours. Host reaction to the injected antibody remains a major drawback to the use of monoclonal antibodies as targeting agents. Iodine-131 is a beta- and gamma-emitter, producing a local tumoricidal effect and allowing accurate dosimetry by means of external scintigraphy. Yttrium-90 is a pure beta-emitter with a greater maximum beta energy and cytotoxic range; however, it is retained in bony tissues, resulting in a dose-related risk of marrow suppression. Bone absorption cannot be measured by external imaging owing to the absence of gamma emission. This lack of accurate dosimetry, coupled with the toxic side-effects of yttrium treatment, make iodine-131 the current isotope of choice.

Abstract
The route, distribution and clearance of intraarterially administered Lipiodol in the liver has been the subject of much speculation. The hepatic microcirculation was therefore studied by in vivo microscopy after injection of Lipiodol into the hepatic artery and the portal vein in rats. After intraarterial injection, Lipiodol rapidly entered the portal branches through arterio-portal communications. Lipiodol also passed through the sinusoids from the portal into the hepatic veins and then into the systemic circulation. Sinusoidal congestion occurred when the oil droplets filled the liver microcirculation and resolved as the oil was cleared. It is of clinical significance to note the passage of the oil into the systemic circulation after arterial injection.

Abstract
Intraarterial injection of Lipiodol has been recommended to differentiate hepatocellular carcinoma from benign lesions such as cavernous hemangioma, because uptake and prolonged retention of the contrast medium is a characteristic of the malignant tumors. In two cases of cavernous hemangioma of the liver in which we injected Lipiodol, uptake and retention up to 3 months was demonstrated. We conclude that the intraarterial injection of Lipiodol may not be reliable in differentiating hepatocellular carcinoma from cavernous hemangioma of the liver.
