Nineteen patients with metastatic liver tumor (9 of gastric cancer, 5 of colon cancer, 2 of pancreatic cancer, one each of mammary cancer, cholecystic cancer, carcinoid of biliary tract) and one patient with primary liver cancer were treated by endogenously induced LAK therapy consisting of transhepatic arterial infusion with ADM or MMC for induction therapy and OK-432 and rIL-2 (TGP-3) for immunotherapy. The following results were obtained. 1) Clinical response for liver tumor showed no CR but 8 cases of PR, for an overall response rate of 42.1%. 2) Reduced tumor marker value was noted in 76.5% cases, and 50% survival term became 349 days after the therapy. 3) Many CD4 and CD8 positive mononuclear cells had infiltrated around liver tumor after therapy by immuno-histochemical staining of surface marker. 4) NK activity of peripheral blood lymphocytes was markedly reduced soon after the therapy and continued for about 4-7 days, while in cases of combined subcutaneous administration with OK-432, NK activity showed only a slight decrease.

In order to improve therapeutic efficacy for metastatic liver cancer, intermittent transarterial administration of BRM in combination with anticancer drugs was performed by use of reservoir apparatus. A total of 22 patients (12 cases of gastric cancer, 6 of colon cancer, 2 of pancreas cancer, 1 of gall bladder cancer and 1 of biliary tract carcinoid) were treated according to the following schedule: both 10 mg of ADM (or MMC) and 0.5 KE (or 1.0 KE) of OK-432 were administered on day 1 and 40 x 10(4) JRU of recombinant interleukin 2 (r-IL 2) on day 4, 7 and 11. The treatment was repeated as many times as possible. In terms of direct antitumor effect and decrease of tumor marker, the response rate was 43% (6 cases out of 14) and 75% (9 cases out of 12), respectively. As for performance status, improvement, no change and deterioration were seen in 4 cases, 8 cases and 3 cases, respectively. Even though 13 patients died, 8 of them survived more than 300 days. In the case of gastric cancer patients with liver metastasis, 50% survival time of 12 cases was 334 days, while that of 30 cases, who were administered anticancer drugs only systemically, was 144 days. In 3 cases the decrease in the size of tumors located in both liver and the other metastases also was seen. Every case developed high grade fever, but an antifebrile was effective. Otherwise severe side effects were not seen. These results indicated that intermittent arterial infusion immunochemotherapy was feasible for the treatment of metastatic liver cancer.

Six cases of primary hepatic carcinoid tumors were studied with combined immunocytochemical and electron microscopic techniques. Positive tumor immunostaining with PHE5, LK2H10, neuron-specific enolase (NSE), serotonin, gastrin, and insulin antibodies was observed. At the ultrastructural level, cytoplasmic dense granules were seen in all the cases tested. This finding supports a putative origin of these carcinoids found in the liver from a pluripotential stem cell. The clinical course and follow-up of these cases suggests that this unusual hepatic neoplasm has a more favorable prognosis than other forms of hepatic cancer.

As a broad generalization, there appears to be little intrinsic difference in the biological behaviour of the common malignant liver tumours in respect of presentation, clinical course, clinical features and prognosis. Whatever the tumour's origin, patients present with some combination of abdominal pain, hepatomegaly, weight-loss and general malaise and death occurs within 3 years of the onset of symptoms. It is the state of the non-tumorous liver (cirrhotic/non-cirrhotic) and the anatomical site of the tumour (as with hilar cholangiocarcinomas) that are responsible for any significant differences. Metastatic carcinoid tumours, epithelioid haemangioendotheliomas, stage IV-S neuroblastomas and the fibrolamellar variant of HCC are exceptions to this rule with a genuinely better prognosis.

39 patients with metastases to the liver from colorectal cancer were treated with liver resection. The average survival time was 25 months. 11 patients are alive after 10 to 102 months. 18 patients had liver resection for primary liver cancer. The average survival time was 27 months. 4 patients are alive after 27 to 84 months. 16 patients had temporary dearterialisation for carcinoid. All the surviving patients were free from symptoms for at least 6 months.

Polyclonal antibodies directed towards synaptophysin were raised against a synthesised peptide corresponding to amino acids 246 to 260 of the human synaptophysin sequence. The antibodies, when applied for immunocytochemical staining, showed a staining pattern identical to that of the commercially available monoclonal antibody SY-38. A radioimmunoassay for measurements of synaptophysin was developed using these antibodies and the peptide as standard and tracer. The radioimmunoassay was used for optimising the conditions for purification of synaptophysin from rat brain. No synaptophysin was detected in blood plasma in humans, not even during an embolisation treatment of tumour metastases in the liver, which induced tumour cell necrosis, in a patient with carcinoid tumours. By radioimmunoassay, synaptophysin was detected in cell homogenate from the PC-12 (160 ng/mg) and LCC-18 (40 ng/mg) cell lines and in the cell culture media. In the LCC-18 cell line the synaptophysin immunoreactivity was found in the plasma membrane, and the presence of synaptophysin was confirmed both by radioimmunoassay measurements and by the Northern blot technique. These data indicate that measurements of synaptophysin using this radioimmunoassay are reliable and that the assay can serve as a useful tool in further explorations of the biological effects of synaptophysin.

In the present study, repeated hepatic dearterialization combined with intra-arterial infusion chemotherapy was performed in patients with unresectable tumors of the liver. Of 36 patients, 16 had primary liver tumors (13 hepatocellular carcinomas and 3 cholangiocellular carcinomas), while 20 had metastatic tumors (7 gastric carcinomas, 10 colon carcinomas, 2 pancreatic carcinomas, and 1 gastric carcinoid). A significantly better survival outcome was found in those with intra-arterial infusion chemotherapy and those without cirrhosis. In the HCC cases, those with the therapy tended to show a better survival as compared with the natural history. Remarkable tumor regression was found in four (67%) of six patients with metastases of gastric cancer.

Three hundred ninety patients who underwent thymectomy for myasthenia gravis (MG) were followed up to investigate the development of associated malignancies. There were 102 patients with thymoma and 288 without thymoma. Malignant neoplasms were detected in ten patients, four of whom already had the tumor at the time MG was diagnosed. Thus, malignancy developed after thymectomy in six patients. Malignant fibrous histiocytoma (MFH) developed in three patients, as well as gastric cancer, gastric leiomyosarcoma, rectal cancer, liver cancer, lung cancer, breast cancer, and thymic carcinoid in one patient each. Nine of the ten malignancies developed in the thymoma group, and only one in the non-thymoma group. The predicted number of patients with malignancy was 2.63 in the thymoma group and 2.65 in the non-thymoma group. Our findings suggest that the presence of thymoma facilitates the occurrence of extrathymic malignancy, and that thymectomy never enhances the occurrence of malignancy but possibly inhibits it.

The use of helical CT, infusing pump and non-ionic contrast media has enabled the evaluation of different hepatic circulatory phases during contrast injection. Starting the acquisition of scans 20 to 30 seconds after the injection at a rate of 3 to 4 ml/sec the arterial enhancing of the liver is depicted. THROMBOSIS OR COMPRESSION OF THE PORTAL VEIN: Hypervascular triangle-shaped was with peripheral base can be seen, secondary to the increased arterial flow to compensate for the diminished portal flow. ARTERIOPORTAL SHUNTS: This condition can be caused by tumors such hepatocellular adenocarcinomas and hemangiomas, trauma, interventional procedures, cirrhosis, AVMs and surgery. INFLAMMATORY LESIONS: Hypervascular areas can be seen during the arterial phase in abscesses or cholecystitis, returning to their normal condition in the arterial phase. ANATOMIC VARIANTS: Third veins coming from the periphery (capsular veins, accessory cystic vein and an aberrant gastric vein) supply enhanced blood earlier than the portal circulation. OTHER CAUSES: In liver cirrhosis diffuse hyperattenuated areas can be seen during the arterial circulation. In right-sided heart failure, pericardial disease and Budd-Chiari Syndrome, "mosaic areas" can also be noted. In other patients these perfusion disorders were considered unknown. TUMORS: The well-differentiated hepatocellular carcinoma is a lesion with a predominant arterial blood supply, thus appearing in general hyperdense in this phase. Hemangiomas may appear as highly hyperdense lesions in the arterial phase and can be misinterpreted as HCC if smaller than 2 cm. (30% of cases). Focal nodular hyperplasia is a benign lesion (vascular malformation associated with focal nodules of hepatocellular hyperplasia) with increased arterial blood supply. Hepatic adenomas show an important hypervascularity during the arterial phase and, if large, they may present a small central scar and or capsule. Low or high-grade dysplastic nodules can sometimes be seen as hypervascular areas during the arterial phase. Although most metastasis are depicted as hypodense lesions sometimes they can show arterial hypervascularity such as carcinoid and pancreatic islet cell metastasis.

Though the results of treatment of primary liver cancer depend on many circumstances, the opportunity to perform a curative liver resection remains the main point in prognosis on survival. The aim of the study was to examine our first experience in the treatment of liver cancer. From 1996 to 2001 we observed 54 patients with liver cancer: 46 hepatocellular and 6 cholangiocellular carcinomas, 1 malignant carcinoid, and 1 carcinosarcoma. In presence of liver cirrhosis (21 patients, 38.8%) hepatic function was evaluated using Child Pugh classification. Lesions were multiple in 28 cases and single in 26 cases. Ten patients (18.5%) were radically resected, 12 patients (22.2%) were managed by laparotomy and biopsy, 2 by percutaneous ethanol injections, 1 by trans-ileocolic portal vein embolization + hepatic artery embolization. There were 7 deaths (28%) and 18 complications (72%) after the surgical treatment. The survival results of patients who underwent resection were better (median 240 days) compared with palliative treatment group (median 113.3 days); by Log-Rank test p=0.208. CONCLUSION. The use of liver resections in patients affected by single or monolateral liver cancer is effective and potentially radical treatment. Mortality and morbidity rate is high. Alternative therapies can be conveniently considered in case of multicentric Child B-C patients.
