To monitor the electron beam therapy some immunological parameters of breast cancer patients previously undergone surgery were tested before, during and after irradiation. Immune complex levels measured by complement consumption technique were not altered by irradiation. Killer cell activity tested in so-called antibody dependent cellular cytotoxicity (ADCC) capacity assay showed a marked decrease in some cases. Based on the phagocytic capacity of the granulocytes the patients could be divided into two groups: one with declining activity and another with rising activity: The majority of the patients (22/45) were humoral leukocyte adherence inhibition (H-LAI) negative before and during irradiation. Those showed positive H-LAI indices before electron therapy had unchanged (7/45) or decreasing (9/45) tendencies during the observation period. Further study is needed to establish the clinical relevance of these in vitro assays used by us.
