13号染色体异常与多发性骨髓瘤

 近年随着荧光原位杂交（FISH）等技术的应用，多发性骨髓瘤（MM）染色体异常检出率明显提高，其中13号染色体异常最为常见，约占50%。定位于13号染色体上的肿瘤抑制基因和微小RNA在MM的发病机制中发挥重要作用。在过去的10年里研究者普遍认为13号染色体缺失（△13）是MM的独立预后不良因素，但目前越来越多的研究证实其预后价值有赖于其他染色体的异常，且随着新型药物的不断应用，其不良预后可以被逆转。

Chromosome 13 abnormalities and multiple myeloma

With the development of FISH and other technique, the detection rate of chromosome abnormalities in multiple myeloma (MM) were increased. Chromosome 13 abnormalities is most common feature (about 50 %). The tumor suppressor gene and micro RNA on chromosome 13 play an important role on pathogenesis of MM. In the last decade, it is widely believed that chromosome 13 abnormalities is independent poor prognosis factor, but the recent more studies conform that its prognosis value is dependent on the other chromosome abnormalities. It is found that the new drugs such as bortezomib appear to reverse the poor prognosis conferred by chromosome 13 deletion.
