Copper and copper-binding protein in liver tumors.
|
| Abstract |
The presence of copper and copper-binding protein was histochemically investigated in 39 hepatocellular carcinomas, 24 metastatic tumors of the liver, and eight benign hepatic tumors. None of the hepatocellular carcinomas was fibrolamellar. The presence of copper (demonstrated by rhodanine) and of copper-binding protein (demonstrated by modified orcein) was simultaneously observed in 11 of the 39 hepatocellular carcinomas (28%). Deposition was mild in three cases, moderate in two cases, and marked in six cases, and it was significantly related to the presence of bile within the tumor. Copper and copper-binding protein granules were not found in metastatic tumors of the liver, and were observed in two of the eight cases of benign hepatic tumors. These results suggest that the presence of copper and copper-binding protein in tumor cells may be found in all variants of hepatocellular carcinomas and not only in fibrolamellar carcinomas as previously suggested, and might be helpful in differentiating primary from secondary liver tumors.
