title: [Radioimmunologic determination of beta 2-microglobulin and carcinoembryonic antigen in the diagnosis of recurrences of rectal cancer].
abstract: The paper is concerned with the results of the determination of beta 2-microglobulin (beta 2-MG) and CEA concentrations in rectal cancer patients to improve diagnosis of recurrences. The CEA content was shown to be the most specific indicator reflecting the course of a recurring tumor process whereas the beta 2-MG test was found inappropriate for the purpose though it might be used in suspected involvement of the urinary organs in a tumor process.
