目的 探讨乳腺浸润性微乳头状癌(invasive micropapillary carcinoma, IMPC)和浸润性癌(非特殊型)(invasive carcinoma of no special type, NST)的临床病理特征差异及其与腋窝淋巴结转移的相关性。方法 回顾性分析2010年8月至2013年8月北京协和医院92例IMPC手术患者的临床病理资料,随机选取368例同期手术的NST患者作为对照组。比较IMPC和NST的临床病理特征并分析其腋窝淋巴结转移的影响因素。结果 IMPC与NST在肿瘤大小[(2.9±1.9)cm比(2.1±1.4)cm,P=0.001]、脉管浸润率(85.9%比6.0%,P<0.001)、腋窝淋巴结转移率(71.7%比47.3%,P<0.001)及转移个数(8.2±9.9比2.9±5.7,P<0.001)、孕激素受体表达(P=0.047)、人类表皮生长因子受体2(human epidermal growth factor receptor-2, HER-2)表达(P=0.009)、Ki-67指数(P<0.001)以及TNM分期(P<0.001)、分子分型(P<0.001)方面的差异均具有统计学意义。肿瘤组织中IMPC成分≤24%、25%~49%、50%~75%以及≥76%者淋巴结转移率分别为73.9%、56.3%、72.2%和77.1%,IMPC的腋窝淋巴结转移率与其在肿瘤中所占比例无关(P=0.347),与肿瘤T分期(P=0.001)、HER-2表达(P=0.029)、分子分型(P=0.003)、P53表达(P=0.003)以及Ki-67指数(P=0.045)相关。NST的腋窝淋巴结转移与肿瘤T分期(P<0.001)、组织学分级(P=0.001)、脉管浸润(P<0.001)、雌激素受体α (P=0.007)、孕激素受体(P=0.031)、HER-2表达(P=0.008)及分子分型(P<0.001)均相关。结论 IMPC是一种具有高脉管侵袭性、高腋窝淋巴结转移率的浸润性乳腺癌,具有与NST不同的病理特征。IMPC成分的多少并不影响腋窝淋巴结转移的程度,其腋窝淋巴结转移的影响因素明显少于NST。 相似文献

目的:探讨乳腺浸润性微乳头状癌超声声像图的特点。方法:回顾分析10例经病理证实的乳腺浸润性微乳头癌的超声图像资料。结果:10例乳腺浸润性微乳头状癌的最大径为15~44 mm,平均28 mm;其超声表现呈不规则形(90%)或卵圆形(10%);边界模糊(80%)或清晰(20%);10例肿块内均为不均质低或稍低回声,60%瘤内见微小钙化灶;血供中等(80%)或少量(20%),阻力指数0.62~0.77,平均0.71;超声弹性成像中3个(50%)肿块评分为4分,3个(50%)肿块评分为2~3分。80%病灶超声诊断为乳腺恶性肿瘤,20%被误诊为乳腺病。超声诊断同侧腋窝淋巴结癌转移的敏感性、特异性、阳性预测值、阴性预测值及准确性分别为100%、83%、80%、100%和90%。结论:乳腺浸润性微乳头状癌的典型超声表现为形态不规则、边界模糊、不均匀低或稍低回声。浸润性微乳头状癌不伴钙化时容易被误诊为乳腺病。超声对腋窝淋巴结癌转移的诊断有较高价值。 相似文献

The purpose of this study was to analyze the clinicopathological and ultrasound characteristics of triple-negative breast cancers (TNBCs) and compare these findings with those for hormone receptor-positive (HR-positive)/human epidermal growth factor receptor-2-negative (HER-2-negative) tumors. Seventy-five TNBCs and 135 HR-positive/HER-2-negative breast cancers were reviewed. Data from conventional ultrasound, Doppler vascularity and elastography were included in the analysis. TNBCs had a higher histologic grade and Ki-67 level. On ultrasound, TNBCs often appeared as microlobulated, markedly hypo-echoic masses with an abrupt interface boundary, posterior acoustic enhancement, absence of calcifications and more characteristics of surrounding tissue. Results from multivariate regression analysis revealed that margin, posterior acoustic features and surrounding tissue features of tumors were independent predictive factors in differentiating TNBCs from HR-positive/HER-2-negative tumors. Our results suggest that a thorough evaluation of sonographic findings might be useful in discriminating between TNBCs and HR-positive/HER-2-negative tumors, which may provide accurate evidence for clinical early diagnosis. 相似文献

目的评价超声、钼靶摄影以及二者综合对乳腺导管内癌的诊断准确性。
方法分析经病理证实的83例乳腺导管内癌的钼靶摄影和超声表现,并比较其诊断准确性。
结果(1)超声表现腺体内低回声实性病变52例(62.7%),导管内实性结节16例(19.3%),囊性病变或乳腺导管扩张7例(8.4%),阴性8例(9.6%);(2)钼靶摄影表现簇状微小钙化53例(63.9%),软组织结节或局部密度增高50例(60.2%),未发现明确病变者9例(10.8%);(3)分类比较超声、钼靶摄影和二者综合分类为可能恶性者分别为47例、53例、67例,2种方法准确率差异无统计学意义(56.6%和63.9%,P=0.169);综合2种方法后诊断准确率高于钼靶摄影(80.7%和63.9%,P〈0.001)。
结论超声和钼靶摄影诊断导管内癌的准确率较低。综合应用2种检查方法可提高诊断准确率。 相似文献

The purpose of this series was to evaluate the sonographic features of invasive cribriform carcinoma of the breast. Between 2004 and 2010, 3 patients had confirmed invasive cribriform carcinoma of the breast in our institution, and all of them underwent sonography. Sonograms showed masses with an oval (n = 2) or irregular (n = 1) shape, partially microlobulated (n = 2) or well‐circumscribed (n = 1) margins, and a hypoechoic (n = 2) or an isoechoic (n = 1) internal echo texture. Sonographic assessments were classified as Breast Imaging Reporting and Data System category 4 in all 3 cases. Although invasive cribriform carcinoma is a rare breast malignancy, awareness of its sonographic features will be helpful for the diagnosis. 相似文献

A photoacoustic volume imaging (PAVI) system was designed to study breast cancer detection and diagnosis in the mammographic geometry in combination with automated 3-D ultrasound (AUS). The goal of the work described here was to validate the design and evaluate its performance in human breast tissues for non-invasive imaging of deeply positioned structures covering such geometry. The good penetration of near-infrared light and high receiving sensitivity of a broad-bandwidth, 572-element, 2-D polyvinylidene fluoride (PVDF) array at a low center frequency of 1 MHz were used with 20 channel simultaneous acquisition. Pseudo-lesions filled with dilute blood were imaged in three human breast specimens at various depths up to 49 mm. With near-infrared light illumination and 256-sample averaging, the extrapolated maximum depth in imaging a 2.4-mm blood-rich lesion with a 3-dB contrast-to-noise ratio in a compressed breast was 54 mm. Three-dimensional photoacoustic volume image stacks of the breasts were co-registered with 3-D ultrasound image stacks, suggesting for the first time that PAVI, based on the intrinsic tissue contrast, can visualize tissue interfaces other than those with blood, including the inner skin surface and connective tissue sheets. With the designed system, PAVI revealed satisfactory imaging depth and sensitivity for coverage of the entire breast when imaged from both sides in the mammographic geometry with mild compression. 相似文献

目的:研究乳腺非特殊类型浸润性癌(invasive carcinoma of no special type, ICNST)组织中性别决定区Y框蛋白(sex determining region Y-box 2, SOX-2)的免疫组织化学(免疫组化)表达, 并分析其与临床病理参数及乳腺癌分子分型间的关系。方法:收集正常乳腺组织标本30例及2005年1月至2012年12月期间在南京军区南京总医院诊治的179 例ICNST患者的病理标本及完整临床病理资料, 通过免疫组化检测ICNST组织中SOX-2及雌激素受体(estrogen receptor, ER)、孕激素受体(progesterone receptor, PR)、人类生长因子受体2(human epidermal growth factor receptor 2, Her-2)、Ki-67蛋白表达情况, 分析包括年龄、临床分期、月经状态、淋巴结转移、组织学分级、复发、死亡情况及ER、PR、Her-2、Ki-67表达结果与SOX-2表达间的关系。结果:SOX-2在乳腺ICNST癌组织中的表达率(34.6%, 62/179)比正常乳腺中明显升高(P<0.05), 且SOX-2蛋白表达与乳腺癌是否复发、淋巴结转移及临床分期有关(P<0.05), 而与组织学分级、年龄、绝经状态、肿瘤直径、Her-2、Ki-67、ER、PR及乳腺癌分子分型无关;Kaplan-Meier法分析显示, SOX-2阳性组较阴性组的无病生存时间及总生存时间缩短(P<0.05);COX回归分析显示, SOX-2表达水平是影响乳腺癌患者无病生存期的独立预后影响因素(P<0.05)。结论:SOX-2的表达与ICNST的发生、进展、复发和转移密切相关, 可能成为评价乳腺癌预后的重要分子生物学标志物, 并为乳腺癌的研究等提供新思路。 相似文献

Objective. To compare the shape of the sonographic image of invasive breast cancer with the shape of the corresponding histopathologic section stained for components of the extracellular matrix, hyaluronan, and collagen. Methods. We studied 22 cases of breast carcinoma. Among them, 13 were visible on both sonography and mammography, whereas 9 were visible only on sonography. We compared the sonographic images with the histologic sections of the same carcinomas after staining with alcian blue for hyaluronan and Masson trichrome for collagen. Results. We have shown that the shape of the sonographic image of breast cancer is similar to the shape of its hyaluronan extracellular matrix. Conclusions. This finding explains why breast sonography is so sensitive for detection of invasive carcinoma and why some invasive cancers are not visible on mammography. 相似文献

目的 探讨雄激素受体(AR)表达阳性与阴性的三阴乳腺癌(TNBC)的钼靶X线表现特征。方法 回顾性分析112例TNBC患者的临床和钼靶X线资料,比较AR阳性与AR阴性TNBC肿瘤分化程度和钼靶X线表现的差异。结果 AR阴性TNBC肿瘤分化程度低于AR阳性TNBC(χ2=6.206,P=0.045)。AR阳性TNBC钼靶X线表现为肿块型17例(17/30,56.67%),钙化型12例(12/30,40.00%),结构扭曲1例(1/30,3.33%);AR阴性TNBC钼靶X线表现为肿块型66例(66/82,80.49%),钙化8例(8/82,9.76%),不对称性致密8例(8/82,9.76%),二者差异有统计学意义(χ2=18.593,P < 0.001)。肿块型病变中,AR阳性TNBC以不规则形为主,而AR阴性者以不规则形和圆形或椭圆形为主,二者差异有统计学意义(χ2=11.615,P=0.003)。AR阳性与AR阴性TNBC间钙化类型无明显差异(χ2=0.108,P=0.743),均以细小多形性钙化为主。结论 AR阴性TNBC分化较差,乳腺X线片表现不典型,肿块外形不规则和伴钙化可列入鉴别AR阴性与AR阳性TNBC的要点。 相似文献
