Immunological alterations induced by adjuvant treatment of postoperative colon carcinoma Duke's B or C with levamisole in combination with 5-FU.

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.
