摘要： 目的 探讨前B细胞集落增强因子（PBEF）基因在结直肠癌中的表达情况，分析其与结直肠癌临床病理特征的关系以及诊断和预后价值。方法 采用免疫组织化学SP法，检测68例结直肠癌组织标本及其癌旁正常组织中PBEF的表达水平，分析PBEF表达水平与肿瘤病理特征及预后之间的相关性。结果 结直肠癌组织和正常肠黏膜组织中PBEF的表达阳性率分别为80.9%（55/68）和29.4%（20/68），两组间差异有统计学意义(χ2=36.41，P＜0.05)。结直肠癌组织中PBEF表达水平与患者年龄（χ2=0.11，P>0.05）、性别（χ2=0.39，P>0.05）、组织学类型（χ2=0.54，P>0.05）、是否穿透浆膜（χ2=1.55，P>0.05）无关，但与分化程度（χ2=6.29，P<0.05）、淋巴结转移（χ2=4.32，P<0.05）、远处转移（χ2=4.16，P<0.05）及临床分期（χ2=7.58，P<0.05）有关。PBEF蛋白表达阳性、阴性患者的5年生存率分别为73.3%、81.8%，两组差异无统计学意义（χ2=0.315，P>0.05）。结论PBEF异常高表达可能与结直肠癌的发生、发展密切相关。

Abstract: ObjectiveTo explore the expression of preBcell colony enhancing factor (PBEF) in colorectal cancer, and analyze the relationship between PBEF expression and the clinical pathological characteristics and its diagnostic and prognostic value. MethodsSixtyeight human colorectal tumor and normal colorectal tissues were collected, and the expression of PBEF was detected by immunohistochemical method. The relationship between the expression level of PBEF and the characteristics of tumors and prognosis was analyzed. ResultsThe positive expression rate of PBEF in colorectal cancer tissues was 80.9%, higher than that in normal colorectal tissues, which was 29.4% (χ2=36.41, P<0.05). The expression level of PBEF had no relationship with age (χ2=0.11, P>0.05), sex (χ2=0.39, P>0.05), histology type (χ2=0.54, P>0.05) or penetrating serosa (χ2=1.55, P>0.05), but significantly associated with the degree of differentiation (χ2=6.29, P<0.05), metastasis of lymph node (χ2=4.32, P<0.05), distant metastasis (χ2=4.16, P<0.05) and clinical stage (χ2=7.58, P<0.05). The 5 year survival rates of patients with positive and negative expression of PBEF were 73.3% and 81.8%, and the difference was not statistically significant (χ2=0.315, P>0.05). ConclusionThe abnormal high expression of PBEF may be closely related to the occurrence and development of colorectal cancer.
