Background: This study aimed to investigate the value of miR-671-5p in multiple myeloma (MM) in diagnostics and prognosis and developed a potential biomarker to improve the prognosis of MM.
Methods: Plasma cells were isolated from bone marrow samples of 80 MM patients, in which miR-671-5p levels were determined. The correlation between miR-671-5p expression with serum creatinine, β-2-microglobulin, lactate dehydrogenase, bone lesions, International Staging System staging, chromosomal abnormalities, and albumin was analyzed. The association between miR-671-5p expression with progression-free survival and overall survival in MM patients was determined.
Results: miR-671-5p expression was reduced and predicted an increased risk of MM. miR-671-5p expression was negatively correlated with serum creatinine, β-2-microglobulin, lactate dehydrogenase, bone lesions, International Staging System staging, and chromosomal abnormalities, and positively correlated with albumin. miR-671-5p expression was augmented in complete response patients and overall response rate patients, and differentiated CR and ORR patients from Non-CR and Non-ORR patients. Furthermore, miR-671-5p low expression was associated with unfavorable progression-free survival and overall survival in MM patients.
Conclusions: In a word, miR-671-5p is associated with worsening clinical properties, increased ISS staging, unfavorable chromosomal abnormalities, and poor prognosis in MM patients.
