[Expression and Clinical Significance of MMSA-8 and MMSA-1 in Bone Marrow of Patients with M2 Acute Myeloid Leukemia].

ABSTRACT

OBJECTIVE: To detect the expression of multiple myeloma-associated antigen (MMSA)-8 and MMSA-1 in bone marrow mononuclear cells of patients with acute myeloid leukemia, and explore their roles in acute myeloid leukemia. METHODS: A total of 83 patients with M2 acute myeloid leukemia in our hospital from January 2019 to January 2020 were selected as research group, during the same period, 15 patients diagnosed iron deficiency anemia were selected as control group. Real-time fluorescence quantitative PCR was used to detect the levels of MMSA-8 and MMSA-1 in bone marrow mononuclear cells. Patients in the research group were divided into remission and non remission according to the clinical curative effect, and were divided into good prognosis, medium prognosis, and poor prognosis according to the prognosis. The relationship between MMSA-8, MMSA-1 and clinical efficacy, prognosis was analyzed. In addition, the general data of patients in the research group were collected, including white blood cell count (WBC), hemoglobin (Hb), platelet count (PLT), and percentage of bone marrow progenitor cells at admission. Pearson method was used to analyze the correlation between MMSA-8, MMSA-1 and clinical data, and MMSA-8 and MMSA-1. RESULTS: The analysis results about mRNA levels of MMSA-8 and MMSA-1 in bone marrow mononuclear cells of patients showed that patients in the research group were significantly higher than those in the control group (P<0.05); In the research group, patients without remission were also significantly higher than those with remission, as well as those with medium and poor prognosis than with good prognosis, while only mRNA level of MMSA-1 in patients with poor prognosis was significantly higher than those with medium prognosis (P<0.05). Pearson analysis showed that MMSA-8, MMSA-1 were positively correlated with WBC (r=0.468, r=0.516), and MMSA-8 was positively correlated with MMSA-1 (r=0.318). CONCLUSION: The levels of MMSA-8 and MMSA-1 in bone marrow mononuclear cells of patients with M2 acute myeloid leukemia are increased, which are closely related to the occurrence and development of the disease, and have certain value for the prognosis.
