Anticancer effects and biodistribution of a new lipophilic anticancer agent, estradiol-chlorambucil (KM2210), dissolved in lipiodol (LPD) were investigated as an intra-arterial chemotherapy (IAC) on Walker 256 carcinosarcoma grown in the liver of 136 Wistar rats. All rats treated with KM2210 (10 mg)-LPD survived for 90 days after administration, whereas none of the rats with LPD alone were alive for more than 19 days. Histological examination revealed that there was no viable tumor cell in the encapsulated necrotic tumor at 21 days after administration. There was no significant liver dysfunction or leukopenia due to KM2210. The biodistribution study using [14C, 3H]KM2210-LPD solution showed that KM2210 accumulated selectively in tumor and that the tumor-to-normal-liver and tumor-to-blood ratios were 10 and 1,000, respectively, at 21 days after administration. These results suggest that KM2210 has potential clinical application in the treatment of human liver cancer.

The antitumor effect of an angiogenesis inhibitor, TNP-470 (AGM-1470, 6-0-(N-chloroacetylcarbamoyl)-fumagillol), administered via the hepatic artery in a medium-chain triglyceride (MCT) solution, in which TNP-470 is very stable, was examined in rats bearing Walker 256 carcinosarcoma in the liver. The MCT solution containing 0.1 mg of TNP-470 completely suppressed tumor growth after a single arterial injection, and the solutions containing 0.5 approximately 5 mg of TNP-470 caused tumor regression function. These antitumor effects lasted for at least 2 weeks. Moreover, the administration of the MCT solution containing 5 mg of TNP-470 also caused remarkable regression of well-developed enlarged tumors 2 weeks after inoculation, indicating potential in the treatment of unresectable hepatic cancer. When the MCT solution containing radiolabeled TNP-470 was injected via the hepatic artery, the initial radioactivity in the tumor was 22 times that in the normal part of the liver and 5.7 times that in the tumor when an aqueous solution of radiolabeled TNP-470 was injected. Also, in the case of the MCT solution, the radioactivity in the tumor was maintained at a relatively high level for over 2 weeks after injection. These results indicate that the remarkable antitumor effect resulted from the selective delivery and prolonged retention of TNP-470 at the tumor site.

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.

Non-hepatocellular carcinoma (non-HCC) with macroscopic bile duct tumor thrombus (BDTT) formation is rare, few radiological studies have been reported. In this case report, we retrospectively analyzed the imaging findings of three cases of non-HCC with macroscopic BDTT on dynamic enhanced multislice computed tomography (MSCT) scan. One case of primary hepatic carcinosarcoma was presented as a solitary, large well-defined tumor with significant necrotic changes. One case of liver metastasis from colon cancer was presented as a lobulated, large ill-defined tumor. One case of intraductal oncocytic papillary neoplasm involved the entire pancreas, presented as a cystic and solid mass with multilocular changes (the individual loculi were less than 5.0 mm in diameter). The bile duct was dilated due to expansible growth of the BDTT in all three patients. The BDTT was contiguous with hepatic or pancreatic tumor, and both of them showed the same enhancement patterns on dynamic contrast-enhanced computed tomography scan: early enhancement in the hepatic arterial phase and a quick wash-out of contrast agent in the portal and equilibrium phases. Macroscopic BDTT in non-HCC patient is rare, dynamic enhanced MSCT scan may be valuable in the diagnosis of non-HCC with BDTT.

Primary liver carcinosarcoma is rare. Here we report an unusual case of liver carcinosarcoma containing combined hepatocellular cholangiocarcinoma. A mass in the right liver lobe of a 45-year-old man was accidentally discovered by ultrasonic inspection and computed tomography (CT) scan. Surgical resection was performed following a diagnosis of primary liver cancer. Micropathologically, both carcinomatous and sarcomatous elements were present, and diagnosis of liver carcinosarcoma was confirmed. The carcinomatous element consisted of hepatocellular carcinoma and foci of cholangiocellular carcinoma. The sarcomatous element was composed of spindle cells and bizarre cells, as well as foci of osteosarcoma and chondrosarcoma. Hepatocellular carcinoma cells diffusely expressed both hepatocyte specific markers cytokeratin (CK) 8/18 and cholangiocyte specific markers CK19, and sarcoma cells were positive for vimentin. Interestingly, both carcinomatous and sarcomatous cells expressed epithelial membrane antigen. CD117-positive ductular reactions and small undifferentiated cells were observed. A liver progenitor cell origin of the liver carcinosarcoma was proposed.

Egyptian fruit bats (Rousettus aegyptiacus) are one of many species within zoologic collections that frequently develop iron storage disease. The goals of this retrospective multi-institutional study were to determine the tissue distribution of iron storage in captive adult Egyptian fruit bats and the incidence of intercurrent neoplasia and infection, which may be directly or indirectly related to iron overload. Tissue sections from 83 adult Egyptian fruit bats were histologically evaluated by using tissue sections stained with hematoxylin and eosin, trichrome, and Prussian blue techniques. The liver and spleen consistently had the largest amount of iron, but significant amounts of iron were also detected in the pancreas, kidney, skeletal muscle, and lung. Hepatocellular carcinoma (HCC; 11) was the most common neoplasm, followed by cholangiocarcinoma (4). Extrahepatic neoplasms included bronchioloalveolar adenoma (3), pulmonary carcinosarcoma (1), oral sarcoma (1), renal adenocarcinoma (1), transitional cell carcinoma of the urinary bladder (1), mammary gland adenoma (1), and parathyroid adenoma (1). There were also metastatic neoplasms of undetermined primary origin that included three poorly differentiated carcinomas, a poorly differentiated sarcoma, and a neuroendocrine tumor. Bats with hemochromatosis were significantly more likely to have HCC than bats with hemosiderosis (P = 0.032). Cardiomyopathy was identified in 35/77 bats with evaluable heart tissue, but no direct association was found between cardiac damage and the amount of iron observed within the liver or heart. Hepatic abscesses occurred in multiple bats, although a significant association was not observed between hemochromatosis and bacterial infection. To the authors' knowledge, this is the first publication providing evidence of a positive correlation between hemochromatosis and HCC in any species other than humans.
