[Possible approaches to the study of the immunological status of cancer patients and healthy people].

The paper is a review of the investigations on the immunological status in patients and healthy people in the light of old and new ideas of immunological surveillance in cases of malignant growth. A discrepancy between peculiarities of malignant growth and changes in the immunological function of the organism is estimated. Some data are given in favour of the importance of revealing nonspecific immunological mechanisms of surveillance when malignant cells appear. The author shows her methods of determining the immunological status of an individual by means of normal antibodies to one of common enterobacterial antigens and the number of leukocytes and lymphocytes in peripheral blood. The immunological functions of the organism are classified. The tests and classification may be suitable for determining the immunological status of population. The last stage of the work can be carried out by means of a suitable mathematical model.
