Recent investigations in several laboratories have shown that the glycoprotein trophic hormones TSH, LH, hCG, and FSH, are composed of two biologically inactive subunits: a common, nearly identical alpha subunit and a beta subunit that confers specificity on the complete biologically active molecule. In the course of screening serums of cancer patients for ectopic placental protein production, we found a case with isolated production of the beta subunit of hCG (a 75-year-old man with mixed epidermoid-adenocarcinoma of the pancreas; serum hCG-β, 300 ng/ml) and another with isolated production of the alpha subunit (a 27-year-old woman with typical gastric carcinoid; serum
