Abstract: Objective To monitor dynamically serum lactate dehydrogenase (LDH) levels in acute leukemia (AL) patients,and to investigate the clinical significance on the monitoring of pathogenetic condition and prognosis evaluation. Methods The LDH levels of 2 170 times from 1 184 de novo AL patients were analyzed retrospectively. The relationship of LDH levels with disease progression and AL prognosis was evaluated.The relationships between LDH levels and blood cell counts,the proportion of bone marrow leukemia cells,cytogenetic abnormality, flow cytometry immunophenotyping and the other related diagnostic markers were analyzed. Results LDH levels of AL patients in different stages of the disease were different. The LDH levels of incipient and relapse stages in AL patients were significantly higher than those of remission stage in AL patients and those in healthy controls (P<0.05). The LDH levels of remission stage in AL patients reduced, but were still significantly higher than those in healthy controls (P<0.05). The LDH levels of acute lymphoblastic leukemia (ALL) patients were significantly higher than those of acute myeloid leukemia (AML) patients (P<0.05). Compared with the other diagnostic and prognostic indicators of AL, LDH levels had correlation with the proportion of bone marrow leukemia cells,cytogenetic abnormality and flow cytometry immunophenotyping (P<0.05). Conclusions The serum LDH levels of AL patients in different stages and different subtypes are different significantly. The LDH levels can be used as a supplementary indicator of AL diagnosis, disease progression and therapeutic effect evaluation.
