 AB    BACKGROUND: Postoperative 5-FU combined with levamisole increases 5 year
       survival in colon cancer patients (Duke C) by 30% (1). In order to
       investigate the potential immunological mechanism, we determined
       lymphocyte subtypes and markers of immune activation in 22 patients
       before and during one year of postoperative adjuvant treatment. METHODS:
       Before and regularly during treatment, according to the scheme described
       by Moertel (1), major lymphocyte subsets were quantified by flow
       cytometry. Serum neopterin, soluble IL2-receptors, beta 2-microglobulin,
       TNF-alpha and interferon-gamma were determined by Elisa. RESULTS: The
       CD4/CD8 ratio increased significantly after levamisole was added to the
       treatment, as did the levels of soluble IL2-receptors. The percentages
       of T-cells expressing the interleukin 2 receptor followed a similar
       trend. The levels of neopterin tended to decrease during the combined
       treatment course. This was paralleled by a progressive fall in the
       proportion of T-cells expressing HLA-DR. CONCLUSIONS: The treatment
       induced significant and consistent alterations in major immunological
       mediators and lymphocyte subtypes. It remains to be established whether
       these changes are related to the therapeutic effect.
