Özet
Aims: We determined plasma levels of dickkopf-1 (DKK-1) and osteopontin (OPN) which have roles in the Wnt pathway in chronic lymphocytic leukemia (CLL) and non-Hodgkin lymphoma (NHL) patients and in healthy controls. We also tested whether DKK-1 and OPN levels could be of clinical or prognostic significance in CLL and NHL. Methods: We included 36 CLL, 24 NHL patients, and 21 healthy controls. Patients' clinical and demographic features, treatment modalities, and response to treatment were recorded. DKK-1 and OPN levels in plasma obtained at initial diagnosis were determined with enzyme-linked immunosorbent assay. Results: CLL patients had significantly lower DKK-1 levels than NHL and control groups (P levels, respectively, 0.048 and 0.017). OPN level was significantly higher in NHL group than in CLL and control groups (P values, 0.017 and <0.001). CLL patients with early and late Rai stages of disease had similar DKK-1 and OPN levels. After a median follow-up of 48 months, 13 CLL patients died. Univariate analysis showed that advanced Rai stages and older age were significantly poor prognostic factors. DKK-1 level in CLL patients who have died was significantly lower than those who were alive (P = 0.035). NHL patients with extranodal involvement had significantly higher OPN levels than those with no involvement (P = 0.04). Conclusions: Our results demonstrated that the Wnt pathway inhibitor DKK-1 was decreased in CLL. OPN was increased in NHL and associated with extranodal involvement. In order to reveal the pathogenic and clinical roles of DKK-1 and OPN in CLL and NHL, larger studies need to be conducted.
