摘要(Abstract):

目的:观察胃肠B细胞性非霍奇金淋巴瘤的临床病理特征,Bcl-2、ki-67、CD5的表达和幽门螺杆菌(Hp)的感染对其临床病理特征及预后的影响。方法:收集18例病人的临床病理资料并进行随访,通过HE及免疫组织化学染色,观察黏膜相关淋巴瘤及氵弥漫大B细胞淋巴瘤的组织学特点,检测Bcl-2、ki-67、CD5及Hp,对所得资料进行统计学分析。结果:CD5、ki-67表达及Hp感染均随着临床分期的增加而增加。Bcl-2阳性组及ki-67表达>30%组的淋巴结累及率要高于Bcl-2阴性组及ki-67表达≤30%组。CD5阳性组的生存状况要好于阴性组,而ki-67表达>30%组及Hp感染组生存状况要差于ki-67表达≤30%组及Hp未感染组。结论:Bcl-2、CD5表达、ki-67高表达及Hp感染可能与晚期淋巴瘤有关,Bcl-2表达、ki-67高表达可能与淋巴结受累有关,而ki-67表达、Hp感染与较差的生存状况相关。
Objective:To observe the clinicopathogical features of gastrointestinal B cell lymphomas,expression of Bcl-2,CD5,Ki-67 and the influence of Helicobacter pylori(Hp) infection to clinicopathogical features and prognosis of patients.Methods:The clinicopathogical data of 18 patients were collected and further follow-up was carried out.The expression of Bcl-2,CD5,Ki-67 and Hp infection were checked by using immunohistochemistry method.All of the data were statistically analyzed.Results:The expression of CD5,and Ki-67,and Hp infection rates increased along with the increasing of the clinical staging of the disease.The rates of lymph node involvement in the groups of Bcl-2-positive and Ki-67 higher(>30%) expression(66.67% and 77.78%) were higher than those in groups of Bcl-2-negative and Ki-67 lower(≤30%) expression(33.33% and 22.22%).The survival rate of CD5-positive group(100%) was higher than that of CD5-negative group(50%),while the survival rates in groups of Ki-67 higher expression and Hp infection-positive(66.67% and 33.33%) were lower than those in groups of Ki-67 lower expression and Hp infection-negative(100% and 83.33%).Conclusion:The advanced stage of the disease seems accompanied by expression of CD5,higher expression of Ki-67 and Hp infection.Lymph node involvement associates with Bcl-2 expression and higher expression of Ki-67.Lower survival rates associate with higher expression of Ki-67 and Hp infection.
