The immunological and clinical significance of EAI was studied. Considering the activity of EAI being corretated with serum CH50 orimmune complex level measured by “Raji cell method”, the activity of EAI is mainly attributed to blood immune complexes.
In addition, concentration of EAI was not correlated with non-specific cellular immunity. However, in the patients with high serum EAI level, the rate of peripheral lymphocytic transformation stimulated with PHA tend to be lower, but that with Con A tend to be higher.
These observation suggested that suppressor T cell was activated by binding with immune complex.
Serum EAI level was studied in patients with 74 gastric cancer and 70 with colon cancer before and after treatment.
The results obtained revealed that EAI was frequently detected in pretreatment cases and it was decreased after operation or immunochemotherapy.
Ultimately, EAI could be one of the specific parameter for diagnosis and treatment of cancer patients from immunological aspects.
