We performed prospective research to assess the accuracy and effectiveness of ex vivo ultrasound for detecting sentinel node metastasis during the operation. Methods: 183 fresh sentinel lymph nodes from 30 breast cancer patients had sonographic examination performed on them by a specialized radiologist immediately after surgical resection. The sonographic criteria for malignant lymph nodes were uneven cortical thickness, a node more than 3 mm in diameter, the absence of the hilum and a round hypoechoic node. After sonographic evaluation, the speci-men were delivered to the department of pathology for frozen biopsy and permanent staining. Results: Among 133 lymph nodes that were examined on frozen sectioning, 12 (9.0%) were revealed as metastatic nodes and 121 (90.9%) were revealed as benign. On US examination, 150 (81.9%) among the detected 183 nodes were read as benign and 33 (18.1%) were read as metastatic. Among 150 benign nodes, four (2.6%) were proven as metastasis on permanent pathology, and 20 (60.6%)
结论:体外超声检查在乳腺癌手术中发现前哨淋巴结有助于判断淋巴结的程度目的:淋巴结转移是否存在是决定是否进行根治性腋窝清扫的关键因素。我们进行了前瞻性研究,以评估手术中体外超声检测前哨淋巴结转移的准确性和有效性。方法:30例乳腺癌患者的183个新鲜前哨淋巴结在手术切除后立即由专业放射科医师对其进行超声检查。恶性淋巴结的超声诊断标准为皮质厚度不均、淋巴结直径大于3mm、淋巴结门缺失、圆形低回声淋巴结。超声评估后,标本被送到病理科进行冷冻活检和永久染色。结果:133例冷冻切片淋巴结中12例(9.0%)为转移性淋巴结,121例(90.9%)为良性淋巴结。在US检查中,发现的183个淋巴结中150个(81.9%)为良性,33个(18.1%)为转移性。150例良性淋巴结中,4例(2.6%)为永久性转移,20例(60.6%)为永久性转移。

Purpose: The extent of the loss of heterozygosity (LOH) has been used as the genetic parameter for the classification and staging of some solid tumors. Breast cancers such as ductal carcinoma in situ (DCIS), and invasive and metastatic lesions, are frequently observed to contain heterogeneous tumor foci. To delineate the relation between the LOH and the progression of breast cancers, three successive histological sites in a tumor lesion were analyzed for LOH events. Methods: We tested 111 tumor site including DCIS, and invasive, and metastatic lymph nodes from 50 breast cancers for LOH using 5 microsatellite makers on 8 chromosomal arms (3p, 4p, 5q, 8p, 9p, 13q, 17p, & 18q). Results: Twenty-four of 34 breast cancers showing intratumoral histological heterogeneity had common chromosomal losses in the heterogeneous tumor sites, as well as having divergent losses that were restricted to a part of tumor lesion (mean divergent loss, 2.32). The number and frequency of heterogeneous chromosomal losses were not significantly related with age, tumor size, and stage. Overall, at least one chromosomal loss was detected in 48 cases, and incidences of LOH in each chromosome were 27.1∼63.3%. A large fraction (58%) of breast cancer patients had 2 to 4 chromosomal losses, and chromosome 8p was most frequently lost (63%). When comparing the number of chromosomal losses in nine cases with all of three progressive lesions, the lost extent was greater in the DCIS (mean losses, 4.44) than in the invasive sites (mean losses, 3.1) and the metastatic lymph nodes (mean losses, 2.9). Moderate-level chromosomal losses involving 3-5 chromosomes were significantly related with lymph node metastasis (p=0.006) and the advanced tumor stage (p<0.005), whereas low-level losses involving 1∼2 chromosomes and high-level losses involving 6∼7 chromosomes were more common in DCIS and early-stage diseases. Conclusion: The DCIS, invasive, and metastatic sites of a breast cancer patient contained common and divergent chromosomal losses. This indicates the concurrent expansion of different subclones was derived from a common ancestor clone, in which an optimal range of chromosomal losses, rather than high-level chromosomal losses, was more frequently associated with lymph node metastasis and the advanced tumor stages.

目的:将杂合性缺失程度(LOH)作为一些实体肿瘤分类和分期的遗传参数。乳腺癌,如导管原位癌(DCIS),浸润性和转移性病变,经常被观察到包含异质性肿瘤灶。为了描述LOH与乳腺癌进展之间的关系,我们分析了肿瘤病变中三个连续的组织学部位的LOH事件。方法:我们使用8条染色体臂(3p、4p、5q、8p、9p、13q、17p和18q)上的5个微卫星制造器检测了111个肿瘤部位,包括DCIS、浸润性和转移性淋巴结。结果:在34例具有肿瘤内组织学异质性的乳腺癌中,有24例在异质性肿瘤部位有共同的染色体丢失,以及局限于部分肿瘤病变的发散性丢失(平均发散性丢失,2.32)。异质染色体丢失的数量和频率与年龄、肿瘤大小和分期无显著相关。总的来说,48例患者中至少有一条染色体缺失,每条染色体的LOH发生率为27.1 ~ 63.3%。很大一部分(58%)乳腺癌患者有2 - 4条染色体丢失,其中8p染色体丢失最为频繁(63%)。当比较9例所有三种进展性病变的染色体丢失数量时,DCIS的染色体丢失程度(平均丢失4.44)大于浸润性部位(平均丢失3.1)和转移性淋巴结(平均丢失2.9)。涉及3-5条染色体的中等水平染色体丢失与淋巴结转移(p=0.006)和肿瘤晚期(p<0.005)显著相关,而涉及1 ~ 2条染色体的低水平染色体丢失和涉及6 ~ 7条染色体的高水平染色体丢失在DCIS和早期疾病中更为常见。结论:一名乳腺癌患者的DCIS,浸润性和转移性部位包含常见和发散性染色体丢失。这表明不同亚克隆的同时扩增来源于一个共同的祖先克隆,其中染色体损失的最佳范围,而不是高水平的染色体损失,更频繁地与淋巴结转移和晚期肿瘤阶段相关。(韩国乳腺癌协会杂志2004;7:217-227)

우리나라에서도 2001년도 들어 구미여성에서와 같이 유 방암이 여성 암의 1위를 차지하면서 1995년도에 비해 불 과 7, 8년 사이에 2배 가까운 비율로 급속히 증가하고 있 는 추세이다.(1) 영국의 외과의사인 John of Aderne가 1307 년 처음으로 남성 유방암에 대해 언급한 이후 20세기에 들어서도 대규모의 연구가 진행되지 않았던 남성 유방암 은 그 분포가 여성 유방암의 경우와 비슷하여 여성 및 남 성 유방암 모두 실제적으로 없는 지역은 없으나, 여성 유 방암의 빈도가 높은 지역이 남성 유방암의 빈도도 높게 보고되고 있다. 인종별, 지역별 예외적인 보고가 있기는 하지만, 남성 유방암의 경우는 여성에서 생기는 경우보다 희귀하고 발견 역시 늦어지는 결과로 예후면에 있어서 좋 지 않은 결과가 우세했다. 그러나 최근 Crichlow 등(2)에 의하면 남성 유방암은 여성과 동일병기를 기준으로 볼 때 같은 생존 및 예후를 나타낸다고 한다. 저자는 1989년부 터 2003년까지 4,809예의 유방암 환자 중 기록이 온전하 며 추적이 가능했던 13예의 유방암을 문헌고찰과 함께 보 고하고자 한다. 제한된 소규모의 임상경험과 정립된 문헌의 부재는 남 성 유방암의 원인과 치료법, 예후 및 생존율의 파악에도 많은 어려움을 주고 있다. 이에 체계적인 작업 하에 확신 있는 결론이 밝혀질 수 있도록 꾸준한 관심과 추적조사가
在我国,2001年也像欧美女性一样,乳房癌占据了女性癌的第一位,与1995年相比,“火与7”8年之间近2倍的比率正在迅速增加的趋势。(1)英国外科医生的john of aderne 1307年首次谈及男性乳腺癌后,进入20世纪都未进行大规模研究的男性乳腺癌是其分布与女性乳腺癌的情况相似,女性及性乳腺癌别人都没有切实的地区,但女性乳癌频率较高的地区男性乳房癌的频率也被报告为较高。虽然有不同人种、不同地区的例外报告,但是男性乳房癌的情况比女性罕见,发现也较晚,因此在预后方面不好的结果占优。但是最近根据Crichlow等(2)的研究,男性乳房癌与女性以同一病期为标准,显示出同样的生存及预后。作者将对1989年至2003年的4809例乳房癌患者中记录完整、可以追踪的13例乳房癌进行文献考察。有限的小规模临床经验和文献的缺失给掌握男性乳腺癌的原因和治疗方法、预后及生存率带来了很多困难。为了能在系统的工作下得出确切的结论,我们需要持续的关心和追踪调查

Once breast cancer has been diagnosed, the most important question is whether the cancer is confined to the breast or has spread to distant sites. The majority of the death of women with breast cancer result from the growth of metastases that do not respond to therapy.(1) The development of more effective therapies should be based on a better understanding of the mechanisms responsible for the spread of cells from the breast to distant sites, including lymph nodes, bone, brain, liver and lungs. A variety of in vitro and in vivo models have been developed to study the biology of metastasis.(2) In general, in vitro assays have been designed to model distinct steps in the process, for example, invasion through the reconstituted basement membranes,(3) or specific binding to endothelial cells isolated from organs where the cancer cells commonly form metastases.(4,5) Such in vitro assays have great practical value for evaluating specific tumor cell behaviors, yet their limitations for predicting in vivo malignancy should always be considered. It is probably impossible to simulate accurately all the events of the metastatic process with in vitro models, especially considering the events that involve interactions with components of the microenvironment at the site of metastasis.(6) Thus, animal models using transplantable tumors that can grow and metastasize predictably in a suitable host have become standard systems for analyzing the metastatic phenotype and testing the efficacy of anti-metastatic therapies. The most common animal models are rodent tumor models, using transplantable tumors, or spontaneously arising or carcinogeninduced mammary tumors of rats and mice.(7) More recently, transgenic mice with different oncogenes targeted to the mammary epithelium have become available and some are suitable for testing specific forms of therapy, such as those designed for tumors that overexpress HER2/neu.(8,9) Immunodeficient rodents, most commonly athymic (also known as nude) of SCID mice, have been used widely for xenograft studies with human cancers. Not all human cancers or established tumor cell lines will successfully grow in immunodeficient mice, at least from a subcutaneous (s.c.) route of inoculation, the most common and for practical purposes the easiest technique to use. The approach of injecting human tumor cells into the normal equivalent mouse organ, known as orthotopic injection, has been adopted as a way to improve tumor take and growth, and has also been shown to increase Despite advances in surgical and clinical management, metastatic disease, notably to the lungs, liver, bone, and brain is the most common cause of death from breast cancer. Two basic principles govern the process of metastasis. First, that the tumors are heterogeneous populations of cells, and second, that the process of metastasis is a sequence of events that depends on tumor cell properties and interactions with the microenvironment at the sites of metastasis. In theory,
一旦乳腺癌被诊断出来,最重要的问题是癌症是局限于乳房还是已经扩散到远处。(1)开发更有效的治疗方法应建立在更好地了解细胞从乳房扩散到远处部位(包括淋巴结、骨、脑、肝和肺)的机制的基础上。各种体外和体内模型已被开发用于研究转移的生物学。(2)一般来说,体外实验已被设计用于模拟该过程中的不同步骤,例如,通过重建基底膜的侵袭,(3)或特异性结合从癌细胞通常形成转移的器官中分离出来的内皮细胞。(4,5)这样的体外实验对评估特定肿瘤细胞行为具有很大的实用价值。然而,它们在预测体内恶性肿瘤方面的局限性应始终予以考虑。用体外模型准确模拟转移过程的所有事件可能是不可能的,特别是考虑到与转移部位微环境成分相互作用的事件。(6)因此,使用可移植肿瘤的动物模型,可以在合适的宿主中生长和转移,已经成为分析转移表型和测试抗转移治疗效果的标准系统。最常见的动物模型是啮齿类动物肿瘤模型,使用可移植的肿瘤,或自发产生的或致癌物诱导的大鼠和小鼠的乳腺肿瘤。(7)最近,已经有了针对乳腺上皮的不同癌基因的转基因小鼠,其中一些适合用于测试特定形式的治疗,例如为过度表达HER2/neu的肿瘤设计的小鼠。(8,9)免疫缺陷啮齿类动物,最常见的是胸腺(也称为裸)的SCID小鼠。已广泛用于人类癌症的异种移植研究。并非所有的人类癌症或已建立的肿瘤细胞系都能在免疫缺陷小鼠体内成功生长,至少从皮下接种的途径来说是这样,皮下接种是最常见的,也是最容易使用的技术。将人类肿瘤细胞注射到正常的小鼠器官中,即所谓的原位注射,已被用来改善肿瘤的吸收和生长,尽管手术和临床管理取得了进展,但转移性疾病,特别是肺、肝、骨和脑的转移性疾病是乳腺癌最常见的死亡原因。转移过程有两个基本原则。首先,肿瘤是异质细胞群,其次,转移过程是一系列事件,取决于肿瘤细胞特性和与转移部位微环境的相互作用。理论上,针对任何转移步骤的抑制剂都有抑制转移进展的潜力。体外实验不能准确模拟复杂的转移过程,有必要使用合适的动物模型来模拟这一过程,并测试靶向抑制剂对乳腺癌转移生长发展的影响。啮齿动物和人类乳腺癌细胞生长和转移的动物模型已经建立,包括针对骨和脑等关键器官转移生长的模型。(《韩国乳腺癌社会2004;7:141 - 147)ꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏꠏ

여성에 있어서 유방은 남성과는 달리 아름다움의 상징 이며 기능면에서도 육아 시 수유 등을 담당하므로, 없어 서는 안 될 중요한 장기이다. 유방 질환은 여성 질환 중 큰 비중을 차지하고 있으며 질병에 대한 인식도가 높아짐 에 따라 유방의 종괴 촉지를 주소로 내원하는 환자의 수 가 증가하는 추세이다. 유방암은 서양에서는 여성의 가장 흔한 암으로 보고되고 있으며, “2001 한국 중앙 암 연례 등록 보고서”에 따르면 자궁암, 위암을 제치고 발생률에 있어서 1위를 차지하였다.(1) 이는 최근 경제적 성장과 더 불어 생활양식의 서구화에 기인한 것으로 여겨진다. 삶의 질에 대한 관심이 고조되면서 유방암에 대한 수술 방법도 다양하게 변화하고 있으며, 최근에는 유방보존수술이 기 존의 근치 유방절제술이나 변형 근치 유방절제술을 대체 하고 있는 추세이다. 저자들은 유방암의 수술적 치료에 관한 국내의 여러 임상고찰 논문들에서 보여지는 것보다 상당히 높은 비율로, 또한 매우 적극적으로 유방보존수술 을 시행하고 있다. 이에 저자는 2001년 1월부터 2002년 12 월까지 만 2년간 부산대학교 병원 외과에서 유방암으로 진단되어 수술한 환자 323명을 대상으로 임상적 고찰을 시행하여 그 치료 성적을 보고하는 바이다.
对于女性来说,乳房与男性不同,是美丽的象征,在功能方面也负责育儿、哺乳等,是不可缺少的重要器官。乳房疾病在女性疾病中占很大的比重,随着对疾病的认识度的提高,到乳房肿块地就诊的患者数量呈增加趋势。乳腺癌是在西方,女性最常见的癌症,被报告为“2001据韩国中央癌症年度备案报告"子宫癌,超越胃癌发生率上,占第一位。(1)这是最近经济增长和更吹由于生活方式的西方化的粽子。随着人们对生活质量的关注日益高涨,对乳房癌的手术方法也发生了多样的变化。最近,乳房保存手术正在代替现有的根齿乳房切除术或变形根齿乳房切除术。作者们的比率比国内有关乳房癌手术治疗的各种临床考察论文中所显示的要高很多,而且非常积极地进行乳房保存手术。为此,作者从2001年1月开始到2002年12月为止的2年时间里,以在釜山大学医院外科被诊断为乳房癌进行手术的323名患者为对象,进行临床考察,并报告其治疗成绩。
