[Expression Level of S100A6 mRNA in MM and Its Clinical Significance].

Objective: To investigate the expression level of S100A6 mRNA in MM and to its clinical significance, and to evaluate its significance.

Methods: The expression level of S100A6 mRNA in MM patients was determined by real time quantitative PCR(RQ-PCR), and its relationship with the clinical features and outcomes of patients was analyzed by statistic method.

Results: S100A6 mRNA was detected in 20 MM patients. Compared with normal persons, the S100A6 mRNA expression in MM patients was higher. In different groups, the S100A6 mRNA expression in MM patients of 3 stages was higer than that in patients of 1 and 2 stages. MM patients with higher S100A6 mRNA expression had poor prognosis and higer extramedullary metastasis rate.

Conclusion: The high expression of S100A6 mRNA is associated with poor prognosis and may be a prognostic molecular marker of MM.
