摘要
Background/Aim: In chronic lymphocytic leukemia (CLL) the absolute neutrophil count (ANC) has generally been reported to be within normal limits and leukocytosis is due to absolute lymphocytosis. However, other cell types such as neutrophils and monocytes may also exceed the normal range in this disorder. The aim of this retrospective study was to evaluate the frequency and prognostic value of neutrophilia defined as an ANC>7x 10(9)/l and monocytosis- an absolute monocyte count (AMC)>1x 10(9)/l in 113 patients with chronic lymphocytic leukemia (CLL). Materials and Methods: We analyzed clinical and laboratory data from the records of patients with CLL followed in the Hematology unit of a tertiary hospital in Israel. Patients were categorized according to their ANC and AMC before treatment and their data compared. Results: In 24 (21%) patients, neutrophilia was present at diagnosis while 40 (35%) had monocytosis. We identified that 9% of cases had neutrophilia with normal AMC. This subgroup of patients had a better prognosis with lower mortality rate, longer time-to-treatment interval and a higher rate of complete or partial response to treatment compared to patients without neutrophilia or monocytosis. Conclusion: The presence of neutrophilia without monocytosis before treatment appears to be associated with a more favorable prognosis in CLL. These observations still need to be confirmed and validated in a larger cohort of patients.
