摘要
目的:探讨乳腺导管原位癌c-erbB-2、孕激素受体(progesterone reieptor,PR)表达与肿瘤组织学及预后的关系。材料和方法:选取无浸润成分的纯导管原位癌56例,通过免疫组化测定其c-erbB-2、PR表达情况,然后分析其阳性表达与肿瘤组织学和预后的关系。结果:56例中低分化导管原位癌28例,中分化15例,高分化13例。高分化组 c-erbB-2、PR的阳性率分别为 7.69%, 92.31% ;中分化组分别为 20%, 46.67%;低分化组分别为 70.43%,10.71%。高、低分化组相比c-erbB2及PR表达均具有显著性差异(P<0.01)。56例中24例行单纯乳腺切除,17例行改良根治术,病人术后无一例复发,5年存活率为100%。15例局部切除病例中,5例术后半年至16个月内复发,其中低分化DCIS 3例,高、中分化各 1例,5例复发病例中 c-erbB-2阴性 1例,阳性4例。结论:导管原位癌组织学分级与 c-erbB-2、PR的表达具有密切关系:高分化DCIS PR表达率较高,而低分化DCIS c-erbB-2表达率较高。肿瘤预后与手术方式、组织学分级、c-erbB-2、PR表达均密切相关?
Objective: To clarify whether the prognosis of breast ductal carcinoma patient and histology related to expression of c-erbB-2, progesterone receptor(PR) of the tumor. Methods: A total of 56 cases of breast pure ductal carcinoma in situ(DCIS)were histologically and immunohistochemically studied. Results: Among 56 DCIS, 28 were poorly-differelltiated, 15 were intermediately-differentiated and 13 were well-differentiated. The positive expression rates of c-erbB-2 and PR were 7.69% and 92.31% in well-differentiated DCIS; 20% and 46.67% in intermediately-differentiated DCIS; 70.43% and 10.71% in poorly-differentiated DCIS, respectively. The positive rate was significently different between the poorly and well differentiated tumor (P<0.01). There were 24 cases received simple mastectomy and 17 underwent modified radical mastectomy. There were no recurrences among these patients and the 5-year survival rate was 100%. In 15 local excision cases, 5 had recurrence between 6-16 months following operation, in which 3 were poorly-differentiated, 1 intermediatelyand 1 well-differentiated. The expression of c-erhB-2 in the five recurrences were positive in 4 cases and negative in 1 cases. Conclusion:The histologic grade of DCIS correlates with the expression of c-erbB-2 and PR. The prognosis was closely related with histologic grade, surgical method and c-erhB-2, PR expression.
