In advanced cancer patients a cell-mediated immunological impairment, both at baseline and during postoperative period, is often found and is associated with poor prognosis. Cortisol is strictly involved in the response to major surgical stress, is an immunosuppressor and causes a redistribution of immunological population cells in different tissues. The aim of the study was to verify serum levels and circadian rhythm of cortisol in patients with colorectal cancer at baseline before surgery and in the postoperative period, and relate it to the immune status.
