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%)","PeriodicalId":414717,"journal":{"name":"Journal of Korean Breast Cancer Society","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134628183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.
