Background: In acute leukemia, many associations have been identified between prognosis and some factors, such as individual antigen expression, cytogenetics, gender, age, high leukocyte level (WBC), platelet count (PLT), and lactate dehydrogenase (LDH), but few are consistent. In this study, we aimed to investigate the cell surface markers and other clinical pathological features for prognosis determination in acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) patients in our population.
Methods: This cross-sectional study was performed from January 2017 to December 2023 in İstanbul Training and Research Hospital and included 113 patients (86 AML and 27 ALL) newly diagnosed with AML (non-APL) and ALL. The following tests were fulfilled for the included patients: complete blood count (CBC), LDH, and flow cytometric analysis using a blood sample or bone marrow aspirate. The effects of surface markers, gender, age, WBC, PLT, and LDH on 24-month survival were evaluated retrospectively.
Results: Among the investigated parameters, lack of CD13 expression and positive CD10, cTdT expressions were associated with poor prognosis in AML patients (p = 0.01, p = 0.04, and p = 0.04, respectively). We have found no association between the surface markers and other parameters with prognosis in ALL patients. Age > 65 years was associated with poor prognosis in both AML and ALL patients (p < 0.001).
Conclusions: CD10, cTdT positivity, and CD13 negativity may predict poor prognosis for AML and can be considered as prognostic biomarkers for AML patients.
