title: [Immunological monitoring of patients with carcinoma of the lung. Study method and preliminary research].
abstract: It is by now an established fact that the status of the immune system stands in some relationship with the onset and evolution of malignancy. To clarify this relationship the authors investigated the immune system of patients with pulmonary carcinoma, with special regard to the functions of the T and B lymphocyte lines. After suitable explanation of their experimental protocol, which involved immunological monitoring and the study of relationships between immunological changes and the extent and histological type of malignancy, and also the effects of any treatments being administered, the authors describe the results obtained in 18 preoperative patients. The study revealed an overall diminution of cell-mediated immune activity: less strongly positive DNCB skin tests, reduced capacity for making E rosettes, reduced blast transformation with PHA. With B lymphocytes the EA rosette test was often depressed, whereas antibody titers were normal or even above normal, and the pokeweed blast test was invariable above normal values. These preliminary results show that at the time of diagnosing malignancy, the greater aggressiveness characteristic of the less differentiated cellular types, or of stages of diffuse malignancy, is associated with overpowering of cell defenses and (within certain limits) enhancement of the humoral response.
