ABSTRACT
<p><b>OBJECTIVE</b>To explore the expression of CC-chemokine Receptor 7 (CCR7) in adult acute leukemia patients, and to analyze the relationship of CCR7 expression with the clinical characteristics of patients.</p><p><b>METHODS</b>The expression of CCR7 in bone marrow samples from adult acute leukemia patients were detected by flow cytometry (FCM), the relationship of CCR7 expression with the clinical characteristics of patients such as sex, age, WBC count, blast cell ratio, CD56 expression, molecular biology, cell genetics, risk stratification, extramedullary infiltration was analyzed.</p><p><b>RESULTS</b>The expression rate of CCR7 in adult ALL and AML patients was 36.8% and 9.6%, respectively, and the expression level of CCR7 in ALL patients was higher than that in AML patients (P < 0.05). The extramedullary infiltration rate was 100% and 41.7 % for CCR7 positive and negative groups of ALL, respectively (P < 0.05). While the mean fluorescence intensity (MFI) in extramedullary infiltration group of ALL was higher than that in none-extramedullary infiltration group of ALL (50.00 ± 10.42 vs 18.14 ± 1.39), respectively (P < 0.05).</p><p><b>CONCLUSION</b>CCR7 is higher expressed in adult acute leukemia cells, moreover its expression rate in ALL is higher than that in AML, and the expression of CCR7 is related with extramedullary infiltration in ALL.</p>
