Objective: Our study aimed to investigate the correlation of long noncoding RNA maternally expressed gene 3 expression with clinical features, treatment response, and survival profiles in patients with acute myeloid leukemia. Methods: Bone marrow samples of 122 de novo patients with acute myeloid leukemia (prior to treatment) and 30 healthy donors (after enrollment) were collected, and long noncoding RNA maternally expressed gene 3 expression was detected by reverse transcription quantitative polymerase chain reaction. According to median value of long noncoding RNA maternally expressed gene 3 expression in patients with acute myeloid leukemia, they were divided into long noncoding RNA maternally expressed gene 3 high expression and low expression patients (which were further categorized as low---, low--, and low- expression patients). Results: Long noncoding RNA maternally expressed gene 3 expression was decreased in patients with acute myeloid leukemia compared to healthy donors. Besides, receiver operating characteristic curve displayed that long noncoding RNA maternally expressed gene 3 distinguished patients with acute myeloid leukemia from healthy donors. In patients with acute myeloid leukemia, long noncoding RNA maternally expressed gene 3 low expression was associated with poor-risk stratification but was not correlated with age, gender, French-American-Britain classification, or white blood cell level. For prognosis, complete remission rate was lowest in long noncoding RNA maternally expressed gene 3 low--- expression patients, followed by long noncoding RNA maternally expressed gene 3 low-- expression patients, long noncoding RNA maternally expressed gene 3 low- expression patients, and was highest in long noncoding RNA maternally expressed gene 3 high expression patients; Kaplan-Meier curves displayed that lower long noncoding RNA maternally expressed gene 3 expression was associated with reduced event-free survival and overall survival; Cox regression analysis showed that lower long noncoding RNA maternally expressed gene 3 expression independently predicted decreased event-free survival and worse overall survival in patients with acute myeloid leukemia. Conclusion: Long noncoding RNA maternally expressed gene 3 may function as a novel marker for effective surveillance and management of acute myeloid leukemia.
