目的:探讨B7-H4蛋白在弥漫大B细胞淋巴瘤(DLBCL)患者淋巴组织中的表达情况及其与临床特征的相关性。方法选取2007年3月至2011年9月在浙江大学医学院附属第一医院血液内科就诊的164例患者,其中142例为DLBCL患者(DLBCL组),9例患者为正常淋巴结(对照组),13例患者为炎症性淋巴结(炎症组),对所有患者淋巴结组织进行样本采集,采用免疫组化方法测定B7-H4蛋白表达,分析B7-H4在三组患者中的表达情况。将DLBCL组按照B7-H4的表达情况分为高表达组与低表达组,分析其表达高低与DLBCL患者临床特征及预后的关系。结果 DLBCL在三组患者中阳性率表达的比较差异有统计学意义(χ2=36.946,P<0.001)。与对照组相比,DLBCL组B7-H4表达水平较高,DLBCL组与炎症组相比表达水平增高,差异均有统计学意义(P<0.001,P=0.002)。DLBCL组的高表达组与低表达组在年龄(χ2=0.009,P =0.932)、性别(χ2=0.007,P =0.925)、临床分期(χ2=0.534,P =0.465)及结外侵犯(χ2=1.932,P=0.165)方面的比较差异均无统计学意义。对患者中位随访40个月,Kaplan-Meier生存分析显示,无论经联合或未联合利妥昔单抗的CHOP化疗,低表达组与高表达组的生存时间比较,差异均无统计学意义(χ2=0.345,P=0.557;χ2=1.001,P=0.317)。结论 DLBCL 患者的肿瘤组织中 B7-H4表达明显增高,提示 B7-H4的表达与DLBCL的发生可能有一定的相关性。
目的:探討B7-H4蛋白在瀰漫大B細胞淋巴瘤(DLBCL)患者淋巴組織中的錶達情況及其與臨床特徵的相關性。方法選取2007年3月至2011年9月在浙江大學醫學院附屬第一醫院血液內科就診的164例患者,其中142例為DLBCL患者(DLBCL組),9例患者為正常淋巴結(對照組),13例患者為炎癥性淋巴結(炎癥組),對所有患者淋巴結組織進行樣本採集,採用免疫組化方法測定B7-H4蛋白錶達,分析B7-H4在三組患者中的錶達情況。將DLBCL組按照B7-H4的錶達情況分為高錶達組與低錶達組,分析其錶達高低與DLBCL患者臨床特徵及預後的關繫。結果 DLBCL在三組患者中暘性率錶達的比較差異有統計學意義(χ2=36.946,P<0.001)。與對照組相比,DLBCL組B7-H4錶達水平較高,DLBCL組與炎癥組相比錶達水平增高,差異均有統計學意義(P<0.001,P=0.002)。DLBCL組的高錶達組與低錶達組在年齡(χ2=0.009,P =0.932)、性彆(χ2=0.007,P =0.925)、臨床分期(χ2=0.534,P =0.465)及結外侵犯(χ2=1.932,P=0.165)方麵的比較差異均無統計學意義。對患者中位隨訪40箇月,Kaplan-Meier生存分析顯示,無論經聯閤或未聯閤利妥昔單抗的CHOP化療,低錶達組與高錶達組的生存時間比較,差異均無統計學意義(χ2=0.345,P=0.557;χ2=1.001,P=0.317)。結論 DLBCL 患者的腫瘤組織中 B7-H4錶達明顯增高,提示 B7-H4的錶達與DLBCL的髮生可能有一定的相關性。

staining in all the patients. The expression levels of B7-H4 were compared in the three groups, and then patients in the DLBCL group were divided into the high expression subgroup and low expression subgroup. The relationship between B7-H4 expression and clinical features, prognosis in DLBCL patients were analyzed. Results There were significant differences of positive expression of B7-H4 in the three groups ( χ2 = 36.946, P < 0.001). Compared with the normal nodes group, B7-H4 was over-expressed in the DLBCL group (P<0.001). The expression of B7-H4 in DLBCL patients were higher than that in the inflammatory group (P = 0.002). There were no statistical differences in age ( χ2= 0.009, P =0.932), gender ( χ2=0.007, P =0.925), clinical stages ( χ2=0.534, P= 0.465) and extranodal infiltrations ( χ2 = 1.932, P = 0.165) between the high expression subgroup and the low expression subgroup. After a median of 40-month follow-up, the Kaplan-Meier survival analysis showed the expression levels of B7-H4 had no effect on the survival time of the patients with DLBCL, no matter whether rituximab joint the CHOP chemotherapy or not ( χ2=0.345, P=0.557; χ2=1.001, P=0.317). Conclusions The B7-H4 over expressed in DLBCL patients, therefore B7-H4 might be related with the incidence of DLBCL.
