An understanding of the basic mechanisms responsible for the pathogenesis of liver neoplasms is needed in order to develop better therapeutic strategies. The present study utilized a pharmacogenetic mouse model to assess the role of cytochrome P4501A1 (Cyp1a1) in modulating genetic damage to oncogenic and tumor suppressor loci following in utero exposure to the polycyclic aromatic hydrocarbon, ...

Neuroendocrine neoplasms (NENs) predominantly arise within the intestinal tract, pancreas, and lung, but may develop in various organs commonly metastasize, especially to liver. Cross-sectional imaging (ultrasound, computed tomography, magnetic resonance imaging) play a central role detection, characterization, management, follow-up of NENs. Imaging features tumors significantly vary as per sit...

Few data are available on patient management in jaundice caused by liver metastases of solid tumors (nonbreast and noncolon origin). We report the first patient series consecutively treated with cisplatin weekly in patients with severe jaundice and liver failure due to underlying metastatic neoplasms. In 4 out of 8 cases, liver function tests were reversed and jaundice disappeared, permitting s...

In a series of related experiments to evaluate the relative toxicity of inhaled radionuclides, beagles were exposed to aerosols containing relatively soluble (chloride) or relatively insoluble (fused clay) forms of 144-Ce and 90Sr. With the solubled 144-CeCl3, significant radiation doses were delivered to the lungs, liver, and skeleton whereas, after 90-SrCl2 exposure, the radiation dose was de...

Cystic neoplasms of the liver are divided into two types: mucinous cystic neoplasm and cystic intraductal papillary neoplasm of the bile duct. We herein report two cases of cystic and papillary neoplasm of the liver which differed from the abovementioned types. Case  1. A 70-year-old man. Radiologically, a cystic tumor measuring 20 mm in diameter was found at the hepatic hilum. Right hepatectom...

Increased serum concentration of alpha-fetoprotein (AFP) can be found in benign and malignant liver diseases, in yolk sac tumors, and in several nonhepatic neoplasms at advanced stage. The frequency and level of elevated serum AFP are highest in hepatocellular carcinoma (HCC) and yolk sac tumors. Most levels of serum AFP in HCC are greater than 500 ng per mL, whereas the serum AFP in most of th...
