[Experiments concerning the value of immunoglobulin-determinations (IgG, IgM, IgA) with respect to the immunological reactions of patients suffering from malignant tumors (author's transl)]. / Untersuchungen über die Wertigkeit von Immunglobulinbestimmungen (IgG, IgM und IgA) zur Beurteilung der immunologischen Reaktivität bei Tumorerkrankungen.

The present paper is a report on the determination of G, M and A serum immunoglobulins of 177 patients (98 men and 79 women) at the age of 19 to 78 years with malignant tumors and of 100 healthy controls of the same setup with respect to age and sex. The results were evaluated by cross-section and longitudinal examinations dependent upon localization, TNM classification, histological differentiation and the therapy of the tumor. The results show that the G, M and A immunoglobulins are not suitable for statements on the situation of the reaction of the organism of tumor bearers and on the prognostic course. Neither is it possible to use the determination of the concentration of serum immunoglobulins for the regulation of a therapy.
