目的

探讨唾液酸路易斯X抗原(SLeX)和乳腺癌1号基因(BRCA1)表达与乳腺浸润性导管癌(BIDC)临床病理指标及预后的关系。

方法

收集2014年5月至2015年12月手术切除的BIDC标本80例及距癌灶3 cm的癌旁乳腺组织30例,应用EliVisionTM plus免疫组织化学2步法检测SLeX和BRCA1在癌组织及癌旁乳腺组织中的表达。运用SPSS 22.0软件分析,SLeX和BRCA1阳性率、临床病理指标等计数资料用例(%)表示,组间比较进行χ2检验及相关性分析,P<0.05为差异有统计学意义。

结果

癌组织SLeX和BRCA1阳性率分别为86.3%(69/80)、60.0%(48/80),癌旁乳腺组织分别为20.0%(6/30)和100%(30/30),差异均有统计学意义(P<0.05)。SLeX在TNM分期(T3+T4)、低分化、有淋巴结宏转移和随访5年间有复发转移患者中高表达;BRCA1在年龄>53岁、TNM分期(T3+T4)、低分化、有淋巴结宏转移和随访5年间有复发转移患者中低表达。

结论

SLeX和BRCA1与BIDC的发生发展显著相关,前者表达上调和(或)后者表达下调均预示癌组织分化差、进展快、预后不良。

Objective

To investigate the relationship between the expression of sialic acid Lewis X antigen(SLeX)and BRCA1 gene and clinicopathological indicators and prognosis of invasive ductal carcinoma of breast(BIDC).

Methods

Retrospective study of 80 BIDC patients surgically resected from May 2014 to December 2015 and 30 para-cancer breast tissues 3 cm away from the tumor were collected. EliVisionTM plus two-step immunohistochemical method was used. SPSS 22.0 software was used to analyze the SLeX and BRCA1 positive rate,clinicopathological indicators and other count data(%). χ2 test and correlation were performed between groups. P<0.05 was considered statistically significant.

Results

The positive rates of SLeX and BRCA1 were 86.3%(69/80)and 60.0%(48/80)for cancer tissues and 20.0%(6/30)and 100%(30/30)for paracancerous tissues,respectively,with statistically significant differences(P<0.05). SLeX was highly expressed in patients with high TNM stage(T3 and T4),low differentiation,lymph node macrometastasis,and recurrence and metastasis within 5 years of follow-up;BRCA1 was low expressed in patients aged >53 years,high TNM stage(T3 and T4),low differentiation,lymph node macrometastasis,and recurrence and metastasis within 5 years of follow-up.

Conclusion

SLeX and BRCA1 were significantly associated with the development of BIDC,and either upregulation of the SLeX or downregulation of the BRCA1 predicted poor differentiation,rapid progression and poor prognosis.
