AIM To identify the clinical features of gastric mucosaassociated lymphoid tissue(MALT)lymphoma with extra copies of MALT1.METHODS This is a multi-centered,retrospective study.We reviewed 146 patients with MALT lymphoma in the stomach who underwent fluorescence in situ hybridization analysis for t(11;18)translocation.Patients were subdivided into patients without t(11;18)translocation or extra copies of MALT1(Group A,n=88),patients with t(11;18)translocation(Group B,n=27),and patients with extra copies of MALT1(Group C,n=31).The clinical background,treatment,and outcomes of each group were investigated.RESULTS Groups A and C showed slight female predominance,whereas Group B showed slight male predominance.Mean ages and clinical stages at lymphoma diagnosis were not different between groups.Complete response was obtained in 61 patients in Group A(69.3%),22 in Group B(81.5%),and 21 in Group C(67.7%).Helicobacter pylori(H.pylori)eradication alone resulted in complete remission in 44 patients in Group A and 13 in Group C.In Group B,14 patients underwent radiotherapy alone,which resulted in lymphoma disappearance.Although the difference was not statistically significant,event-free survival in Group C tended to be inferior to that in Group A(P=0.10).CONCLUSION Patients with t(11;18)translocation should be treated differently from others.Patients with extra copies of MALT1 could be initially treated with H.pylori eradication,similar to patients without t(11;18)translocation or extra copies of MALT1. 展开更多

Taji et al . have reported in their study on 13 patients with gastric mucosa-associated lymphoid tissue (MALT) lymphomas an aggressive tumor course in trisomy 3 positive cases. The authors analyzed only stage I patients with classical low-grade marginal zone lymphoma of the MALT type and detected the trisomy 3 using an alphasatellite DNA probe directed to the centromere. Their data support the observation that trisomy 3 is the most frequent cytogenetic aberration in MALT lymphomas . 展开更多

Trisomy 18 (Edwards Syndrome) was first reported in 1960 by Edward et al. in a newborn with multiple abnormalities, and is a broad clinical presentation involving more than 130 different abnormalities. Most cases die during the embryonic or fetal life. Only 5% - 10% of the live-born cases survive the first year of life. Prenatal diagnosis is possible. However, the prenatal detection compels parents to make a difficult decision. After the birth of the baby, it also places a material and moral burden on both the family and the national economy due to multiple congenital abnormalities and limited lifespan. On the other hand, pediatricians experience difficulties in making a decision on interventions, especially cardiac surgery and resuscitation, due to the comorbid abnormalities in the neonatal intensive care units, in which medical ethics arises for discussion. The current study presents a case diagnosed with trisomy 18 by chromosome analysis, who was found to have multiple abnormalities with ultrasonography (USG) during the prenatal period and born because the patient’s mother, who was advised to have amniocentesis, decided to continue with the pregnancy. 展开更多

目的:采用血清三联[甲胎蛋白(AFP)、游离雌三醇(uE3)、总β人绒毛膜促性腺激素(Total-βHCG)]筛查19 730名孕中期妇女,以探讨三联筛查对唐氏综合征和18三体综合征诊断的临床价值。方法:检测2008年5月至2010年4月间19 730名单胎孕中期妇... 目的:采用血清三联[甲胎蛋白(AFP)、游离雌三醇(uE3)、总β人绒毛膜促性腺激素(Total-βHCG)]筛查19 730名孕中期妇女,以探讨三联筛查对唐氏综合征和18三体综合征诊断的临床价值。方法:检测2008年5月至2010年4月间19 730名单胎孕中期妇女的血清AFP、uE3、Total-βHCG水平,取其中位数倍数(multiple of median,MoM),并结合孕妇体重,计算胎儿发生唐氏综合征及18三体综合征的风险率。根据唐氏综合征和预期分娩年龄(expected date of delivery,EDD)为35.5岁时的自然发生率约为1∶380,本研究将唐氏综合征三联筛查的临界值(cut-off)设定为1∶380,将18三体综合征筛查的临界值设定为1∶334。对风险率大于临界值的孕妇行羊水细胞染色体分析。结果:19 730名孕妇中,唐氏综合征风险率大于临界值者有1 130名,阳性率为5.73%,对1 130名唐氏综合征风险率大于临界值的孕妇进行羊水细胞染色体核型分析,发现有6例胎儿为唐氏综合征,其中EDD<35.5岁以下者有4例;唐氏综合征三联筛查风险率小于临界值的18 600名孕妇中共产下4例唐氏综合征患儿,假阴性率为40.0%(6例检出,4例漏检),其中EDD<35.5岁的孕妇有3例;18三体综合征筛查风险率大于临界值者有102名,占0.52%,经羊水细胞染色体核型分析,结果有3例胎儿为18三体综合征,18三体综合征筛查阴性的孕妇中无18三体综合征患儿出生。结论:孕中期行血清三联(AFP、uE3、Total-βHCG)筛查,对于EDD<35.5岁的孕妇有较高的胎儿唐氏综合征和18三体综合征筛出率,但也漏检了3例EDD<35.5岁的孕妇。对于漏检孕妇的数据进行回顾分析可发现,75%的漏检孕妇筛查结果提示风险率大于1∶1 000,而如血清三联筛查采用临界值为1∶700,则能使将检出唐氏综合征胎儿数提高到9例。 展开更多
