Abstract
The distribution of carcinoembryonic antigen (CEA), secretory component (SC), fat globule membrane antigens (FGMA), and keratin was determined immunohistochemically in 22 invasive adenocarcinomas of various types and in 9 adenocarcinomas in situ of the uterine cervix. In the invasive adenocarcinomas 77% were positive for CEA, 47% for SC, 89% for keratin, and 77% for FGMA. In adenocarcinomas in situ 67% were positive for CEA, 11% for SC, and 44% for keratin. The location of the markers was variable in the cells, and the cells in a tumor were irregularly positive. For a given histologic type there were several phenotypes. No correlation was found between histologic types of invasive adenocarcinomas and the various phenotypes. It remains to be shown whether a particular phenotype has a particular biological behavior. The detection in the serum of the markers shown in histologic preparations could be useful in the postsurgical monitoring.
