Abstract:
Objective:To detect the expression of CRLF2 in adult Ph negative acute B lymphocytic leukemia (B-ALL) in newly diagnosed cases, and to investigate the relationship between CRLF2 and the general clinical characteristics, efficacy and prognosis.
Methods:103 cases of newly diagnosed adult B-ALL patients were investigated from Apr 2016 to Dec 2017 in the Department of Hematology, Henan Cancer Hospital. Bone marrow samples was used to detect the expression of CRLF2 in leukemic cells. The expression of CRLF2 ≥20% was defined as CRLF2-high group and <20% was defined as CRLF2-low group. The clinical characteristics and prognosis of the two groups were compared.
Results:The Median overall survival (OS) and disease free survial (DFS) in CRLF2-high group were 9.0 months and 4.25 months, respectively. CRLF2-low group were 15.5 months and 10.25 months, respectively. There was a statistically significant difference in median OS and DFS between the two groups (P=0.007, P=0.000) . The 18-month OS and DFS in CRLF2-high group were 38.6% and 25.1%, respectively. CRLF2-low group were 57.8% and 42.3%, respectively. Multivariate analysis showed high expression of CRLF2 was an independent risk factor for OS (HR=2.991, 95% CI 1.429-6.261, P=0.004) and DFS (HR=2.374, 95%CI 1.146-4.960, P=0.041) in patients.
Conclusion:Patients with high expression of CRLF2 had poor prognosis.
