[Expression of lymphocyte activation markers in patients with gastrointestinal tumors at different stages]

Patients with gastrointestinal tumors revealed relatively high levels of activated lymphocytes. CD25 expression at later stages was much higher than at earlier ones (I-II). A relationship between CD25, CD71 and CD95 expression was established for metastatic spread of gastrointestinal tumors as well as a correlation between CD71 and CD98 expression for favorable course. A distinct activation phenotype can be identified for peripheral blood lymphocytes in burgeoning tumor which should be taken into account in prognosis.
