The study aims to evaluate the production of interleukin-2 in patients with gastrointestinal cancer compared to healthy controls.
Measured interleukin-2 levels in 60 control subjects and 45 gastrointestinal cancer patients (14 localized, 31 advanced).
Assessed peripheral blood T cell subsets using monoclonal antibodies.
Compared IL-2 production across groups using statistical analyses.
Advanced cancer patients produced significantly less IL-2 (26.5 +/- 7) compared to controls (61.1 +/- 9, P<0.0001) and localized cancer patients (59.4 +/- 13, P<0.02).
Impaired IL-2 production could not be restored by in vitro irradiation of lymphocytes, indicating potential intrinsic deficiencies.
Similar T cell subset percentages were noted across all groups, suggesting that helper T cell function deficits underlie IL-2 production issues.
