title: Ovarian and hepatic metastases of gastric carcinoma associated with high serum levels of human chorionic gonadotropin (hCG), alpha-fetoprotein (AFP), and carcinoembryonic antigen (CEA): a case report.
abstract: A 45-year-old woman who underwent gastrectomy for gastric carcinoma which had metastasized to the liver and ovaries, showed high serum levels of hCG, AFP and CEA. To locate the source, an immunohistochemical technique was utilized. HCG-producing cells were detected in poorly differentiated adenocarcinoma of a primary tumor and an ovarian metastatic site, and AFP-producing cells in poorly differentiated adenocarcinoma forming a medullary pattern of primary site and metastatic foci. CEA-producing cells were found diffused in primary tumor and metastatic foci. From the viewpoint of oncodevelopmental gene expression (Cancer Res 36:3423, 1976), it is interesting that the serum levels of these three tumor markers (hCG, AFP, CEA) were elevated simultaneously.
