摘    要:目的探讨胃黏膜相关淋巴组织(MALT)结外边缘区淋巴瘤t(11;18)(q21;q21)染色体易位的发生情况及相关临床意义。方法采用间期荧光原位杂交(FISH)方法对18例胃MALT淋巴瘤进行检测。结果 3例检测到t(11;18)(q21;q21),发生率16.7%(3/18)。1例黏膜相关淋巴组织淋巴瘤易位基因1(MALT1)拷贝数增加,发生率5.6%(1/18)。结论 t(11;18)(q21;q21)是胃MALT淋巴瘤具有特异性的诊断指标,而间期FISH是检测t(11;18)(q21;q21)有效而可靠的方法。评估MALT1基因数目可能有利于预测胃MALT淋巴瘤患者的临床过程。

Abstract:Objective To examine the incidence of the t (11 ; 18) (q21 ; q21) translocation in gastric extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) and to explore its related clinical significance. Methods Interphase fluorescence in-situ hybridization (FISH) was used to evaluate the translocation in 18 cases of gastric MALT lym- phoma. Results t(11;18)(q21;q21) was detected in 3 of 18 (16.7%) cases. Extra copies of mucosa associated lymphoid tissue lymphoma translocation gene 1 (MALT1) were detected in 1 of 18 (5.6%) cases. Conclusion t(11;18)(q21;q21) occurs specifically in gastric MALT lymphoma; interphase FISH is useful for demonstrating this characteristic translocation. The assessment of copy number of MALT1 may be valuable for predicting the clinical course of patients with gastric MALT lymphoma.
