[Local cellular immune reactions in cancer patients].

The analysis of 178 cases of stage I-II breast cancer showed morphological features of local cell-mediated immune reactions to be of limited prognostic value. A comparative evaluation of some characteristics of cell surface receptors, such as ability to spontaneous rosette formation with sheep erythrocytes and sensitivity to theophylline, was carried out in lymphocyte samples obtained from tumor tissue and peripheral blood of 76 cancer patients. The said parameters were studied in breast cancer patients with respect to presence or absence of regional metastases. Several patterns of rosette-forming cell reaction to theophylline were identified, the incidence of some of them being determined by the presence or absence of regional metastases. The level and functional activity of surface receptors of tumor mononuclear cells proved to influence prognosis.
