Chronic Lymphocytic Leukemia (CLL) is the most common leukemia in adults. Recently CD38, ZAP70 and hTERT activity have been studied for the evaluation of the prognosis of CLL besides clinical staging and lymphocyte doubling time. There are inconsistent results regarding these markers for the evaluation of the prognosis in CLL patients. In this study CD38, ZAP70 and hTERT values in CLL patients were measured to make comparisons between each other and known prognostic factors. Thirty CLL patients who were included in the study were followed up for 5 years after the initial diagnosis. The mean hTERT value in CLL and control cases were 1.00±1.31 and 3.89±3.58, respectively (p< 0.05). The mean CD38 and ZAP70 were 6.20±7.60 and 5.51±5.67, respectively. No significant association was detected between CD38, ZAP70 and hTERT activity. There was no correlation between those parameters and known prognostic parameters such as Rai staging, peripheral lymphocyte levels, age, and sex of the patients, beta-2 microglobulin and reply to treatment in CLL. The overall five-year survival rate in CLL patients is 96.7%. The overall five-year survival rate in CLL patients is 96.7%. In conclusion, further studies including larger series of patients with longer follow-up periods are recommended.
