We report the results of transcatheter intraarterial perfusion of liver with the emulsion of iodized oil and cytostatics performed as palliative treatment in three patients with hepatic metastases of pancreatic endocrine tumors. Two patients had insulinoma and one patient had glucagonoma. They were also treated by medical therapy from the time the diagnosis was made. Intraarterial perfusion of the liver was achieved by Lipiodol emulsified with streptozotocin and 5-fluorouracil. Regarding these three patients therapeutic responses were different in duration of hormone secretion decrease. Relief of hypoglycemic attacks and a significant decrease of plasma immunoreactive insulin concentration within 12 months without any additional therapy was observed in the patient with insulinoma (case no. 2). This patient had slightly increased immunoreactive glucagon concentration from the time of diagnosis. A decrease of immunoreactive insulin levels in other patient with insulinoma and an increase in plasma glucose to the euglycemic range during two months allowed a reduction of doses of somatostatin analogue and diazoxide. Due to rapid progression of the disease, intraarterial perfusion of liver was repeated three months later with the same results. Remission of symptoms was partial in the case of glucagonoma. Immunoreactive glucagon levels were not changed and there was no significant benefit of the treatment. Intraarterial perfusion of liver with iodized oil and cytostatics could be an effective, safe and repeatable method of palliating symptoms of malignant pancreatic tumors, especially in inoperable but nonterminal cases. It could allow reduction of additional medical therapy, but success of the treatment is not predictable.

Hepatocellular carcinoma is responsible in France for approximately 5,500 deaths per year. Incidence rates are growing and the general status of patients is improving mainly because of earlier diagnosis and improvement in the treatment of complications of liver cirrhosis. In most of the cases the severity of the underlying liver disease is the prominent prognostic factor. Its treatment remains a difficult challenge for oncologists. Unfortunately surgery is usually contraindicated. Most trials of systemic chemotherapy are disappointing with poor response rates and severe side effects; new drugs and direct delivery in the hepatic artery appear to be of interest. Results with interferon are interesting but requires more studies. The lack of efficacy of antiandrogenic and antiestrogenic treatments were recently demonstrated; a recent randomized study showing the interest of somatostatin requires confirmation. Reports on radiotherapy are anecdotals. A lot of studies using liver directed therapies were conducted worldwide. Percutaneous ethanol injections (PEI) are well tolerated and are highly effective in small solitary tumors (> 70% of complete necrosis) but less in larger tumors; recurrences are frequent. No randomized trial have been performed concerning PEI but survival rates seem similar to those of surgery. A randomized controlled trial recently demonstrates that injection of acetic acid is more effective than injection of ethanol. Chemoembolization was extensively studied because of the demonstration of objective responses but all trials failed to demonstrate an improvement in survival. Intraarterial injection of radioactive Lipiodol achieves the same response rate and the same survival than chemoembolization but is significantly best tolerated. This treatment is superior to best supportive cares in patients with portal vein thrombosis. In conclusion, despite the fact that this disease is very frequent we have currently too many treatment options and are lacking of simple rules. The best treatment remains prevention, and the efficacy of hepatitis B vaccination was recently demonstrated in Taiwan.

Our objective was to report the outcome in patients with liver metastasis from endocrine tumors who underwent transarterial chemoembolization (TACE) as first-line non-surgical treatment. From January 1990 to December 2000, 14 patients with progressive unresectable liver metastases from digestive neuroendocrine tumor were treated with TACE (mean of 3.6 sessions) before any non-surgical treatment (somatostatin analogue, chemotherapy or interferon). Liver involvement was less than 50% in 11 patients. Size of the largest lesion ranged from 1.5 to 10 cm. Ten patients presented with carcinoid symptoms. The TACE was performed with Doxorubicin emulsified in Lipiodol and gelatin sponge particles. Symptomatic response upon flushes and/or diarrhea was complete in 7 of 10 cases and partial in 2 of 10 cases. An objective morphologic response was noted in 12 of 14 cases. The 5- and 10-year survival rate from diagnosis was 83 and 56%, respectively. Six patients were alive at the end of the study after 27-100 months from first TACE and 38-142 months from diagnosis. Three of them were successfully palliated for 55, 69, and 100 months with only TACE as treatment. Long-term palliation is possible in unresectable liver metastases from digestive neuroendocrine tumors with a few sessions of TACE as first-line and eventually exclusive treatment.

Chylothorax is a rare but generally severe complication of surgery of congenital heart disease. The authors report the clinical history of a young boy with complex congenital heart disease operated on several occasions and who developed severe and recurrent unilateral chylothorac after a bicavo-bipulmonary derivation. Conservative treatment followed by continuous somatostatin infusion was ineffective. Diagnostic Lipiodol lymphography was required before the chylothorax was cured. The authors describe management of this difficult case and discuss the therapeutic possibilities with reference to a brief review of the literature.
