Recent studies have identified a high prevalence of the L265P mutation in lymphoplasmacytic lymphoma (LPL)/Waldenstrom macroglobulinemia (WM) cases, whereas low frequencies have been observed in other B cell non-Hodgkin lymphomas (NHLs).
We evaluated the sensitivity of the mutant enrichment 3'-modified oligonucleotide (MEMO)-PCR technique, a new detection method. We examined the L265P mutation in a series of Korean patients with LPL/WM and other B cell NHLs in bone marrow aspirates, using the MEMO-PCR technique.
The sensitivity of MEMO-PCR was estimated to be approximately 10-16.7%. L265P was detected in 21 of 28 LPL cases (75%) and only three of 69 B cell NHL cases (4.3%).
Although MEMO-PCR had relatively low sensitivity, we confirmed the high prevalence of the L265P mutation in Korean LPL patients. Our study suggests the diagnostic value of L265P for differentiating B-cell NHLs.
近期研究发现，L265P突变在淋巴浆细胞淋巴瘤（LPL）/华氏巨球蛋白血症（WM）病例中普遍存在，而在其他B细胞非霍奇金淋巴瘤（NHL）中发生率较低。
我们评估了一种新的检测方法——突变富集3'-修饰寡核苷酸（MEMO）-PCR技术的敏感性。我们使用MEMO-PCR技术检测了一系列韩国LPL/WM患者及其他B细胞NHL患者骨髓穿刺液中的L265P突变。
MEMO-PCR的敏感性估计约为10-16.7%。28例LPL病例中有21例（75%）检测到L265P突变，而69例B细胞NHL病例中仅3例（4.3%）检测到该突变。
尽管MEMO-PCR的敏感性相对较低，但我们证实了韩国LPL患者中L265P突变的高发生率。我们的研究表明L265P对鉴别B细胞NHL具有诊断价值。
