目的探讨P53,BRCA1在三阴性乳腺癌中的表达及其意义。方法免疫组化检测56例三阴性及72例非三阴性乳腺癌中P53,BRCA1蛋白的表达。结果三阴性乳腺癌和非三阴性乳腺癌中P53的表达率分别为60.7%(34/56),34.7%(25/72),BRCA1的表达率分别为38.9%(24/56),57.1%(44/72),差异均有显著性(P<0.05)。 P53,BRCA1表达与组织分级和腋淋巴结转移相关。结论在三阴性乳腺癌中P53高表达、BRCA1低表达,BRCA1表达与P53过表达呈负相关(P<0.05)。
目的探討P53,BRCA1在三陰性乳腺癌中的錶達及其意義。方法免疫組化檢測56例三陰性及72例非三陰性乳腺癌中P53,BRCA1蛋白的錶達。結果三陰性乳腺癌和非三陰性乳腺癌中P53的錶達率分彆為60.7%(34/56),34.7%(25/72),BRCA1的錶達率分彆為38.9%(24/56),57.1%(44/72),差異均有顯著性(P<0.05)。 P53,BRCA1錶達與組織分級和腋淋巴結轉移相關。結論在三陰性乳腺癌中P53高錶達、BRCA1低錶達,BRCA1錶達與P53過錶達呈負相關(P<0.05)。

Objective To analyze P53 and BRCA1 expression in the triple-negative breast cancer and its significance .Methods The immunohistochemical method was used to detect the expression of P 53 protein and BRCA1 protein in 56 cases of triple-negative and 72 cases.Results The expression rates of P53 were 60.7%(34/56) and 34.7%(25/72),respectively,in the triple-negative and non-triple-negative cases,and those of BRCA1 were 38.9%(24/56) and 57.1%(44/72).There was significant difference (P<0.05).P53,BRCA1 were correlated with the grade of histology and themetastasis of axillary's lymph nodes in breast cancers.Conclusion P53 protein is high ex-pressed in triple-negative breast cancer and BRCA1 protein is low expressed.Expression of BRCA1 protein is negative related to P53 protein's over-expression(P<0.05).
