SERUM IMMUNOGLOBULIN LEVELS IN CANCER-PATIENTS .2. SERUM IMMUNOGLOBULINS AND STAGE OF TUMOR PROGRESS

Abstract

A study of the IgG [immunoglobulin G] IgA and IgM levels in relation to the clinical course of tumors revealed the IgG values to correlate with the progress of the disease. Their levels rose from stage I to stage III of the classification according to tumor progress, the difference between these stages being of statistical significance. A similar trend, though statistically nonsignificant, was also noted in IgA levels, but these were higher than the values reported for the apparent normal population. The rising tendency in the IgG, and the less striking one in the IgA levels, were also confirmed by a comparison of the mean values of collections separated by a definite time interval in the same patients for the deteriorated and unchanged cases, but not for improved patients.
