[Study of various serum proteins in lung cancer. Immunoglobulins A, G, M, haptoglobin, alpha-1-antitrypsin, alpha-2-macroglobulin]

Abstract

A statistical study of the plasma concentration of immunoglobulin, alpha-1-antitrypsin, haptoglobin, and alpha-2-macroglobulin in 153 patients with primary carcinoma of the lung showed a strong increase in alpha-1-antitrypsin, haptoglobin and A and C immunoglobulins, whilst alpha-2-macroglobulin increases very moderately, and IgM does not vary. The relationships between variables are also modified, thus there appears a correlation between IgA and IgG to the detriment of the IgG/IgM relationship. Furthermore the coefficient of the correlation IgG/alpha-2-macroblobulin is lower in cancer patients.
