雌、孕激素受体和Her-2阴性乳腺癌的临床病理特征

Objective To study the clinicopathologic characteristics of triple-negative breast cancer (TNBC) and its value in the prediction of prognosis. Method In this study,500 cases of female breast cancers were examined immunohistochcmically for the TNBC. The clinicopathologic characteristics of the 243 TNBC cases were inspected. Results TNBC accounted for 17.6% (88/500) of the 500 breast cancers. The histological types of the TNBC included mainly infihrative ductal carcinoma, metaplastic carcinoma and medullar carcinoma. Among those, histological grade Ⅲ accounted for 72.7% (64/88) of all the TNBC and was more common than that in hormone receptor positive breast cancers (HR+ group ) and Her-2 overexpression breast cancers (Her-2 group)(P=0.000). The positive rates of CK5/6 and EGFR in the TNBC were 30.7% (27/88) and 34.1% (30/88), respectively. The positive rates of ERCC1 and KIT in the TNBC were 28.4% (25/88) and 34.1% (30/88), respectively, Both of which were higher than those in the HR + group and Her-2 group, respectively (P=0.032 and P=0.026). 3-year survival rate of the TNBC was 71.5% and it was lower than that of HR group (P=0.021) and not significantly different from that of Her-2 group (P=0.474). Conclusions TNBC is the breast cancer with high aggressive pathologic futures and poor prognosis. EGFR and ERCC1 expression were positive in a portion of TNBC cases.     

雌、孕激素受体和Her-2阴性乳腺癌的临床病理特征

目的 评价雌、孕激素受体和Her-2表达均阴性乳腺癌(triple-negative breast cancer,TNBC)的临床病理特征及其对预后的影响.方法 500例乳腺癌采用免疫组化筛选TNBC,观察TNBC的临床病理特征,并对其中243例乳腺癌进行临床随访. 结果 500例乳腺癌中TNBC占17.6%(88/500).组织学类型主要为浸润性导管癌(NOS)、化生性癌和髓样癌.组织分级Ⅲ级占72.7%(64/88),高于激素受体阳性组和Her-2高表达组(P=0.000).TNBC中CK5/6阳性率30.7%(27/88),EGFR阳性率34.1%(30/88).TNBC中ERCC1和KIT阳性率分别为28.4%(25/88)和34.1%(30/88),均分别高于激素受体阳性组和Her-2高表达组(P=0.032和P=0.026).TNBC 3年累积生存率为71.5%,低于激素受体阳性组(P=0.021),与Her-2高表达组差异无统计学意义(P=0.474). 结论 TNBC是一类具有高侵袭性病理特征和预后不良的乳腺癌;部分病例表达EGFR和ERCC1.

多房囊性肾细胞癌12例临床病理分析

多房囊性肾细胞癌(multilocular cystic renal cell carcinoma,MCRCC)是一种少见的临床亚型,2004年WHO将其命名为一种独立的肾癌类型.病理学定义为完全由囊腔构成的肿瘤,囊腔间隔内有小灶状透明细胞,与Ⅰ级透明细胞性肾细胞癌不能区别.在多房囊性肾细胞癌中癌细胞数量很少,诊断困难,通过免疫组化检查,囊腔间隔内的透明细胞上皮性标记物CK、EMA阳性,而组织细胞标记物CD68阴性,有助于提高疾病诊断的准确性.

乳腺间质CD34和平滑肌肌动蛋白免疫组化检测在乳腺癌诊断中应用

目的 :评价免疫组化检测乳腺间质纤维细胞CD34和平滑肌肌动蛋白 (SMA)表达在乳腺癌诊断中价值。方法 :6 7例乳腺活检组织进行CD34和SMA免疫组化检测 ,其中乳腺癌 4 2例 ,乳腺良性病变 2 5例。观察各类乳腺病变间质的CD34和SMA表达状况 ,并分析CD34和SMA表达的相关性。结果 :2 5例良性病变中CD34表达 10 0 % (2 5 / 2 5 ) ,SMA表达 4 8% (12 / 2 5 )。 34例浸润性乳腺癌 (不包括 8例单纯导管内癌 )CD34全部缺乏表达 (0 /34) ,SMA表达 10 0 % (34/ 34)。CD34和SMA表达在乳腺浸润性癌和乳腺良性病变中表达的差异均具有显著性 (P<0 .0 1和P <0 .0 1)。导管内癌 (单纯导管内癌 8例和伴有浸润性癌的导管内癌成分 13例 )导管周围间质的纤维细胞CD34和SMA表达不均一 ,呈现为不同程度丢失CD34表达和获得SMA表达 ,并且CD34和SMA的表达呈负相关 (r= 0 .931,P <0 .0 1)。结论 :本研究结果表明乳腺间质纤维细胞CD34表达缺乏是浸润性乳腺癌间质改变的一项敏感指标。导管内癌管周间质的纤维细胞CD34和SMA表达不均一体现了从原位癌向浸润性癌发展的过程 ,因此 ,导管内癌管周间质丢失CD34 纤维细胞同时出现SMA 肌纤维母细胞反应可能是癌细胞向间质浸润的前兆。
