effect of chemotherapy on serum level of ccl2 in acute myeloid leukemia patients with monocytic differentiation

Background and objectives: acute myeloid leukemia (aml) is a malignancy that involves the bone marrow and peripheral blood. some chemokines play a role in the progression, migration and tumor initiation and are therefore associated with poor prognosis. ccl2 promotes tumor growth and is associated with poor prognosis in aml patients. we investigated effects of chemotherapy on serum level of ccl2 in aml patients. methods: throughout this case-control study, blood samples were collected from 25 healthy individuals and 25 aml (m4 and m5) patients before and after the first stage of the current chemotherapy regimen (7+3). serum level of ccl2 was measured using commercial elisa kits. data were analyzed in spss 22 using the two-sample t-test and paired t-test. results: before chemotherapy, serum level of ccl2 was significantly higher in the patients than in the healthy controls. following chemotherapy, the serum level of ccl2 reduced significantly to a level comparable to that of the healthy controls. conclusion: the current chemotherapy (7+3) can effectively inhibit ccl2 in aml patients.
