Abstract
Glucocorticoid receptors (GR) have been suggested to have prognostic significance in patients with CLL treated with chemotherapy containing glucocorticoid. In this study, the GR levels in 65 patients with advanced CLL and immunocytoma (clinical stages III and IV according to Rai) were determined by means of a whole cell assay. The median GR-level was 1,920 bs/c with a range from 0 to 9591. The patients were subsequently treated according to a prospective, randomized trial with either a combination of chlorambucil and prednisolone, or with prednimustine. No significant difference in receptor levels was found between responders (median = 1940 bs/c; n = 47) and non-responders (median = 1950 bs/c; n = 14). To assess the influence of receptor content on prognosis we have analyzed the relationship between GR content and survival time and duration of response. There was no significant difference in duration of response and in survival between those patients with high (> 1920 bs/c) and those with low GR levels (< 1920 bs/c) (log-rank test). Our data suggest that determination of GR provides no reliable indicator for clinical response to regimens with glucocorticoid as a component in patients with CLL and immunocytoma.
