Differential expression of miRNAs as biomarkers for predicting the outcomes of diffuse large B-cell lymphoma patients.

Biosci Rep 2021 Jun 10. Epub 2021 Jun 10.

Anhui Provincial Hospital, Hefei, China.

Background: Diffuse large B-cell lymphoma used to be defined as germinal center B-like and non-germinal center B-like subtypes, associated with different prognoses, but the conventional classification does not meet the needs of clinical practice because of diffuse large B-cell lymphoma heterogeneity, a problem that might be improved by selection of miRNAs as biomarkers.

Methods: Twelve patients with diffuse large B-cell lymphomas were used to screen out the aberrant miRNA profile using miRNA microarray technology in 2 patient subtypes (6 germinal center B-like and 6 non-germinal center B-like patients). The potential biomarkers were further analyzed using the quantitative reverse transcription-polymerase chain reaction method in 95 diffuse large B-cell lymphoma patients to investigate relationships between expression levels of potent miRNA, clinicopathological features, and survival rates of patients.
