[Parameters of humoral immunity in patients with breast carcinoma during therapy with leukocyte interferon].
The values of parameters of humoral immunity, such as concentration of immunoglobulins IgG, IgA, and IgM, as well as the absorbance of patients serum at 450 nm (A4 5 0) in the presence of PEG 6000 (as a measure of the presence of immune complex in circulation, CIC) in a group of breast cancer patients stage T + N0 M0, after surgical tumor resection, and before and after various therapy phases with the leucocyte IFN therapy are given. The IFN (product of Torlak, Belgrade, or Immunological Department Zagreb) therapy was performed in four therapy phases. During the first month (first phase) 3.10(6) U IFN-alpha were administered i.m. every day, during the second month 3.10(6) U were administrated thrice weekly, during the third month 3.10(6) U IFN-alpha were administered i.m.twice weekly, and during the fourth month 3.10(6) U IFN were administered i.m. once a week. The average concentration of IgG, IgA, and IgM fall in the range of normal values during the therapy. Nevertheless, some mild stimulation of the IgG production and transient one for IgA can be noticed. The average value of A4 5 0 for patients was before therapy significantly (P less than 0.05) higher than normal value--at the end of the therapy it was in the range of normal A4 5 0.
