  • Title: [Immunological diagnosis of cancer].
    Author: Mach JP.
    Journal: Schweiz Med Wochenschr; 1975 Oct 11; 105(41):1301-7. PubMed ID: 56032.
    Abstract:
    Two different types of immunological reaction are of assistance in the diagnosis of cancer: The first is detection of a weak immunological response of the patient toward his own tumor cells. Unfortunately the currently available techniques for the demonstration of humoral or cellular immunological reaction against autologous tumor cells are not reproducible enough to be recommended as routine clinical tests. Secondly, it is possible to use antisera, obtained by immunization of animals with human tumor extracts, for the detection of substances released into the blood by the tumor cells. The two major antigens associated with human cancer that can be measured in the blood by very sensitive immunological methods are the alphafetoprotein (AFP) and the carcinoembryonic antigen (CEA). It is very important for the physician to be fully alive to the usefulness and limitations of such tests in order to interpret them correctly. Clinical situations in which the measurement of AFP and CEA can provide useful information are reviewed.
