Abstract
Axillary lymph node dissection (ALND) has been the standard axillary treatment for breast cancer for a long time. However, ALND is associated with postoperative morbidities, including local sensory dysfunction, reduced shoulder mobility and most notably arm lymphedema. Recently, ALND can be avoided not only in clinically node-negative (cN0) patients with negative sentinel lymph nodes (SLNs), but also in patients with less than 3 positive SLNs receiving breast radiation, axillary radiation, or a combination of the two. Moreover, SLN biopsy has been adopted for use in clinically node-positive (cN +) patients presenting as cN0 after neoadjuvant chemotherapy (NAC); ALND may be avoided in cN + patients who convert to SLN-negative following NAC. Patients who undergo SLN biopsy alone have less postsurgical morbidities than those who undergo ALND. Nevertheless, ALND is still required in a select group of patients. A variety of conservative approaches to ALND have been developed to spare arm lymphatics to minimize arm lymphedema. These conservative procedures seem to decrease the incidence of lymphedema without increasing axillary recurrence. In the era of effective multimodality therapy, full conventional ALND removing all microscopic axillary disease may now be unnecessary in both cN0 patients and cN + patients. Regardless, emerging procedures for ALND should still be considered as investigational approaches, as further studies with longer follow-up are necessary to determine the safety of conservative ALND to spare arm lymphatics.

Abstract
Currently, it is standard practice that patients with negative sentinel lymph nodes (SLNs) do not undergo axillary lymph node dissection (ALND), whereas ALND is mandated in those with positive SLNs. However, the Z0011 trial showed that ALND could be safely omitted in selected patients with positive SLNs. This article presents a review and discussion of the current role and practice of ALND in the surgical management of breast cancer. A review of the English-language medical literature was performed using the MEDLINE database and cross-referencing major articles on the subject. It may be concluded that ALND can be avoided not only in patients with negative SLNs but also in those with positive SLNs who undergo breast-conserving therapy with whole-breast irradiation and appropriate systemic therapy. However, the omission of ALND would be indicated only in patients with a low axillary tumor burden. On the other hand, ALND remains a standard method of treating regional disease not only in patients with clinically positive nodes but also in other SLN-positive patients who do not meet the above criteria. Although the role of ALND has been limited to the prevention of axillary recurrence, SLN biopsy with whole-breast irradiation and systemic therapy can replace ALND in patients with a low axillary tumor burden.

Abstract
Sentinel lymph node biopsy (SLNB) has almost completely replaced complete axillary lymph node dissection (CALND) as the first-line axillary procedure for clinically node-negative early stage breast cancer. We assessed the incidence of axillary relapse in patients with negative SLNB who had no additional CALND (group 1, n = 481) and in patients whose SLNB contained micrometastases and had no further CALND (group 2, n = 45). All patients were operated on between November 1997 and December 2005 and followed at the Jules Bordet Institute. The median follow-up was 48 months. A mean of 2.2 sentinel lymph nodes was removed per patient. Axillary relapse was observed in only one patient (0.2%) in group 1 and in none of the patients in group 2. This study confirms that the axillary recurrence rate after long-term follow-up of patients with a negative sentinel lymph node is very rare, provided that the selection criteria are judicious.

Abstract
In breast cancer, axillary lymph node status is one of the most important prognostic variables and a crucial component to the staging system. Several clinico-histopathological parameters are considered to be strong predictors of metastasis; however, they fail to accurately classify breast tumors according to their clinical behavior and to predict which patients will have disease recurrence. Methods based on genome-wide microarray analyses have been used to identify molecular markers with respect to the development of axillary lymph node metastasis. Most of these markers can be detected in the primary tumors, which can potentially lead to the ability to identify patients at the time of diagnosis who are at high risk for lymph node metastasis, allowing for early intervention and more suitable adjuvant treatments.

Abstract
AIMS Currently, it is standard practice to avoid ALND in patients with negative SLN, whereas this procedure is mandated for those with positive SLN. However, there has been some debate regarding the necessity of complete ALND in all patients with positive SLN. This review article discusses the issues related to eliminating the need for ALND in selected patients with positive nodes. METHODS A review of the English language medical literature was performed using the MEDLINE database and cross-referencing major articles on the subject, focusing on the last 10 years. RESULTS Currently, complete ALND is mandated in patients with SLN macrometastases as well as those with clinically positive nodes. It is not clear whether SLN biopsy is appropriate for axillary staging in patients with initially clinically positive nodes (N1) that become clinically node-negative (N0) after neoadjuvant chemotherapy. Although there is debate regarding whether ALND should be performed in patients with micrometastases in the SLN, it seems premature to abandon ALND in clinical practice. Moreover, it remains unclear whether it is appropriate to avoid complete ALND in patients with ITC-positive SLN alone. CONCLUSIONS In the absence of data from randomised trials, the long-term impact of SLN biopsy alone on axillary recurrence and survival rate in patients with SLN micrometastases as well as those with ITC-positive SLN remains uncertain. These important issues must be determined by careful analysis of the results of ongoing clinical trials.

Abstract
The technique of detection and resection of the sentinel lymph node applied to early breast cancer management aims to spare the patient with a low risk of lymph node involvement an unnecessary axillary lymphadenectomy. This innovating technique lies on the double hypothesis of an accuracy to predict non sentinel lymph node status and to induce a lower morbidity when compared with axillary lymphadenectomy. This multidisciplinary technique depends on surgeons, nuclear physicians and pathologists. In practice sentinel lymph nodes are detected thanks to two types of tracers, the Blue and the colloids marked with technetium, harvested by the surgeon guided by the blue lymphatic channel and the use of a gamma probe detection, analyzed by the pathologist according to a particular procedure with the concept of serial slices, and possibly immuno histo chemistry. The objectives of this review are to specify the state of knowledge concerning the different steps: detection, surgical resection and the pathological analysis of the sentinels lymph nodes and to focus on validated and controversial indications, and on the main ongoing trials.

Abstract
In breast cancer surgery, there has been a major shift toward less invasive local treatment: from extended or radical mastectomy to modified radical mastectomy, from modified radical mastectomy to breast conserving therapy, and from routine axillary lymph node dissection to sentinel lymph node biopsy. Many breast surgeons have experienced an evolutionary progression of surgical management of breast cancer. However, there is an increasing demand for minimally invasive and non-surgical treatment methods for patients with small breast cancer. Radiofrequency (RF) ablation is the most promising among non-surgical ablation techniques in the treatment of breast cancer, although it is still in the investigative stage. Nevertheless, surgery still plays an integral role in the treatment of breast cancer, because local therapy is important for enhancing survival in the presence of systemic therapy. In clinical practice, surgical oncologists must individualize treatments, selecting a surgical or non-surgical procedure that provides the best local control, does not compromise the chances of cure, and achieves the best cosmetic results.

Abstract
PURPOSE Our previous study based on the results of polymerase chain reaction and Southern hybridization for the detection of Human papilloma virus (HPV), Cytomegalovirus (CMV), Epstein-Barr virus (EBV), Herpes simplex virus (HSV)-1, HSV-2, and Human herpesvirus (HHV)-8 DNA in non-familial breast cancer patients suggest that the viruses associated with breast cancer are HHV-8 > EBV (P < 0.01). Therefore, efforts were made to further investigate the association between breast cancer with nodal status and viral infections. METHODS Sixty-two breast cancer patients and their mammary specimens were enrolled in this retrospective study. The presence of these six potential oncogenic viruses was analyzed to establish the relationship between nodal status and treatment outcome. Statistical analyses were used for the assessment of variables, including viral positivity and clinical feature. RESULTS Viral positivity was not significantly different comparing node-positive and node-negative patients (P > 0.05). When the viral factors were not entered for statistical analyses, no variable was significantly related to overall survival. However, tumor stage, tumor size, nodal status , and estrogen receptor were significantly related to relapse-free survival (P < 0.05). For viral factors, the number of infecting viruses is related to the overall and relapse-free survivals. Only when V0 or V(0, 1) was grouped for comparison with other multiply virus-infected subgroups, were the overall and relapse-free survivals significantly different (P < 0.005 or P < 0.001). The results suggest that HSV-1, HHV-8, EBV, CMV, and HPV were related to overall survival, however, only HHV-8 and CMV were related to relapse-free survival (P < 0.05 or P < 0.01). CONCLUSION Virus factor is significantly related to human breast cancer, not only in terms of the oncogenetic process, but also in overall and relapse-free survivals.

Abstract
A great deal of clinical experience has firmly established the concept of the sentinel lymph node (SN) in breast cancer. SN biopsy allows treatment without axillary lymphadenectomy and has made it possible to perform a surgical intervention via just a small skin incision. In partial resection of the breast (quadrantectomy), we use a double retractor to form a workspace under the skin via a small axillary incision. Resection does not require a large incision even in cases in which the cancer lesion is located in the upper inner or lower inner quadrant of the breast, as the endoscope allows the surgeon to see the workspace formed by the double retractors.

Abstract
BACKGROUND AND OBJECTIVES As infraclavicular lymph node metastases is one of the parameters of stage III-C, the diagnostic techniques aiming to identify the metastases of this region have gained importance recently. In this study, we investigated the presence of axillary and infraclavicular lymph node metastases with ultrasonography. METHODS Axillary and infraclavicular lymph nodes were evaluated by preoperative ultrasonography in 100 consecutive breast cancer patients. Median age was 47 (23-76) years. RESULTS Ultrasonography identified lymph nodes correlating with metastases in the infraclavicular region in 20 patients. In 19 of these patients, metastases were verified in the lymph nodes with histopathologic examination (false positivity rate 5%). Of the 80 patients who were not considered as having metastases by ultrasonography, 59 had no metastatic lymph nodes on histological examination. The specificity of ultrasonography in the identification of metastatic lymph nodes in the infraclavicular region was 98.3%, with a sensitivity of 47.5%, positive predictive value of 95%, negative predictive value of 73.7%, and overall accuracy of 78%. CONCLUSIONS Patients who were identified to have infraclavicular lymph node metastases by preoperative ultrasonographic examination should have a relevant treatment plan as they are classified as locally advanced, stage III-C disease.

Abstract
BACKGROUND AND METHODS Sentinel lymph node (SLN) biopsy is a useful way of assessing axillary nodal status in breast cancer patients. Recently, several surgeons have begun to abandon routine axillary dissection on the basis of negative SLN biopsy results. However, there is no long-term data comparing outcomes of SLN biopsy alone with those of axillary dissection. This paper reviews and discusses the significance of ongoing prospective randomized clinical trials aiming at the elimination of axillary dissection. RESULTS SLN biopsy is known to have a false-negative rate. It can thus be assumed that SLN biopsy alone may fail to remove the disease completely from the axilla in some patients. As a result, it is not known whether SLN biopsy alone will increase the axillary recurrence rate, particularly in patients with a high risk of axillary lymph node metastasis. Recently, moreover, locoregional control appears to be important for enhancing survival in conjunction with adjuvant systemic therapy. It is therefore still unclear to what extent the benefits of SLN biopsy outweigh the risks and, if so, for which patient groups. CONCLUSION Before SLN biopsy can replace routine axillary dissection, research using long-term regional controls and investigation of survival in a prospective randomized trial are essential. Except for clinical research studies, routine axillary dissection should not be abandoned until and unless there is documentation of extensive experience and a low false negative rate. Even with such evidence, however, patients undergoing SLN biopsy without concomitant axillary dissection should be informed of the risk of a false-negative result.

Abstract
BACKGROUND AND METHODS This review examines the various methods of detecting occult breast cancer metastasis in the sentinel lymph node (SLN). The prognostic relevance of such micrometastases and isolated tumour cells, and their impact on stage migration and decision making with respect to axillary dissection and adjuvant systemic therapy, are discussed. RESULTS Examination of SLNs by serial section with haematoxylin and eosin and/or immuno histochemical staining significantly increases the detection rate of micrometastases, even in patients with very small (T1) tumours. However, the prognostic relevance of isolated tumour cells and small micrometastases is uncertain. Moreover, deciding which patients might benefit from axillary dissection is complicated by the fact that adjuvant radiotherapy and systemic chemotherapy alone may eradicate most micrometastases. CONCLUSION Ongoing randomized trials comparing the results of SLN biopsy alone with those of axillary dissection should answer the question of whether isolated tumour cells and small micrometastases are clinically relevant. This should also indicate which patients with SLN micrometastasis are likely to benefit from axillary dissection. In this sense, SLN biopsy must be considered still to be at an investigative stage; outwith clinical trials complete axillary dissection should be performed on all patients with SLN micrometastasis.

Abstract
No standard method for handling and histopathologic examination of the sentinel node (SN) exists. We hypothesized that a focused examination of all nodes with serial sectioning and cytokeratin immunohistochemical staining would confirm the SN as the node most likely to harbor metastasis. Intraoperative lymphatic mapping and sentinel lymphadenectomy using blue dye and (99m)technetium-labeled sulfur colloid were performed. All nodes were stained with H&E. All tumor-free nodes underwent additional sectioning and staining with H&E and an immunohistochemical stain. Routine H&E examination detected SN metastases in 27.6% of cases. Occult SN metastases were identified in 12.7% of cases. None of the 724 non-SNs examined contained occult metastases. The SN false-negative rate was zero. This study confirms histopathologically that the SN has biologic significance as the axillary node most likely to harbor metastatic tumor Standardization of the handling, sectioning, and staining of the SN is necessary as lymphatic mapping and sentinel lymphadenectomy become integrated into the care of patients with breast cancer

Abstract
This paper reviews the Japanese literature regarding sentinel lymph node (SLN) biopsy in an attempt to provide an overview of existing controversies and to suggest a method for the identification of the SLN and the detection of micrometastases in the SLN to eliminate unnecessary axillary lymph node dissection (ALND). The combined dye- and gamma probe-guided method resulted in the accurate identification of the SLN in 96% of patients, compared with 80% when the dye-guided method alone was used. Although neither 99m-Tc sulfur colloid nor 99m-Tc colloidal albumin is commercially available in Japan, 99m-Tc stannous phytate and 99m-Tc rhenium colloid appear to be ideal tracers for identifying SLNs. Moreover, subdermal injection over the primary tumor or subareolar injection was found to enhance SLN identification, although these injection routes do not lead to detection of internal mammary SLNs. Furthermore, the accuracy of SLN diagnosis using frozen sections as well as imprint cytology improved with an increase in the number of sections, and could attain a sensitivity comparable to that obtained with routine histologic examination of permanent sections. As a result, several surgeons have begun to offer the option of forgoing ALND to patients with negative SLN. Although subsequent relapse in the axilla has not yet been reported, longer follow-up periods are needed to assess accurately the incidence of axillary failure in these negative SLN patients.

Abstract
BACKGROUND AND METHOD This paper reviews and discusses the feasibility and accuracy of sentinel lymph node (SLN) biopsy in breast cancer. A standardized method of identifying the SLN and detecting micrometastases is suggested, along with a strategy for the elimination of routine axillary lymph node dissection (ALND). RESULTS Although the SLN can be identified successfully by experienced practitioners using either the dye-guided or gamma probe-guided method, identification is facilitated when the two techniques are combined. To improve the likelihood of spotting metastases in the SLN, it is desirable to perform step sectioning combined with haematoxylin and eosin staining and immunohistochemistry of permanent and frozen sections. SLN biopsy is as accurate for T2 tumours as it is for T1 tumours. However, it is highly unlikely that all false-negative cases can be eliminated, even by detailed histological examination. Nevertheless, patients with T1 tumours with micrometastases in the SLN have shown no evidence of tumour in the non-sentinel nodes. In other words, ALND can be avoided in these patients, even if histological examination of the SLN fails to detect micrometastasis. CONCLUSION In practice, routine ALND can be avoided in patients with T1 tumours when the identified SLN proves to be histologically negative. However, investigation of long-term regional controls and of survival in a prospective randomized trial is necessary before SLN biopsy can replace routine ALND, particularly for patients with T2 tumours.

Abstract
The diagnosis of axillary disease remains a challenge in the management of breast cancer and is a subject of controversy. In 1998, the Japanese Breast Cancer Society conducted a study assessing axillary lymph node involvement in breast cancer. The study included (a) clinical assessment by pre-operative imaging modalities, (b) histologic assessment for peritumoral lymphatic invasion, (c) biologic assessment by gelatinolytic activity using film in situ zymography, and (d) sentinel lymph node (SLN) biopsy. Clinical assessments by CT, PET, and US as well as biologic assessment were limited in their ability to detect axillary lymph node disease, although these imaging techniques may be useful to exclude node-positive patients from the need for SLN biopsy. Histologic assessment for peritumoral lymphatic invasion was useful, particularly for detecting false-negative cases by SLN biopsy. Nevertheless, the utility of SLN biopsy in assessing axillary nodal status was confirmed. Axillary lymph node dissection (ALND) can be avoided in patients with a small tumor and a negative SLN. However, further studies will be required to investigate the value of SLN biopsy for predicting regional control and survival before it can replace routine ALND as the optimal staging procedure for operable breast cancer.

Abstract
BACKGROUND The purpose of this study was to determine the feasibility of sentinel lymph node (SLN) biopsy using blue dye with or without isotope localization to predict the presence of axillary and internal mammary lymph node (IMN) metastases in patients with breast cancer. We also investigated whether multiple sectioning of the SLN could improve the accuracy of frozen section examination. METHOD One-hundred twenty-six patients underwent dye-guided or dye- and gamma probe-guided SLN biopsy followed by complete axillary lymph node dissection (ALND). No ALND was performed in the 14 patients with small tumors and a negative SLN. In addition, 69 patients underwent IMN biopsy. RESULTS The axillary SLN was identified in 123 of 140 (88%) patients. An accuracy rate of 90% was obtained by frozen section examination of the SLN, which increased to 100% in patients examined with a greater number of sections. Lymphatic flow to the IMN and/or a radioactive hot spot in the IMN was found in 9 of 102 (9%) patients, while a hot node was detected using a gamma probe in only 2 of these patients. No involvement of the IMNs was found histologically in these 9 patients. IMN involvement was found in 7 of 61 (11%) patients without lymphatic flow to the IMNs or a hot spot by lymphoscintigraphy or who did not undergo lymphoscintigraphy. CONCLUSION ALND can be avoided in patients with small breast cancers and a negative SLN. SLN biopsy guided by lymphatic mapping is unreliable for identifying metastases to IMNs.

Abstract
PURPOSE We investigated the validity of sentinel lymph node (SLN) detection after radioactive isotope and/or blue dye injection in patients with cervical cancer. PATIENTS AND METHODS Between December 1998 and May 2000, 50 patients (mean age 44 years) with cervical cancer FIGO stage I (n = 32), stage II (n = 16), or stage IV (n = 2) underwent SLN detection during primary operation (radical laparoscopic-vaginal or abdominal hysterectomy, exenteration). The day before surgery 1 ml of Albu-Res labeled with 50 MBq Technetium 99m was applied into the cervix at 3(00), 6(00), 9(00), and 12(00). Blue dye injection (Patentblue) occurred intraoperatively into the cervix at the same locations. RESULTS The detection rate of SLN was 78%. Ten patients (20.0%) were diagnosed with lymph node metastases. No SLN was detected in 10 patients, of which 4 patients had positive lymph nodes. Sensitivity and negative predictive value were 83.3 and 97.1%, respectively. The false-negative rate was 16.6% (1 of 6 patients). After the combined injection, the detection rate, sensitivity, and negative predictive values were 100%. A mean of 2.7 pelvic and 2.6 para-aortic SLNs were detected. Para-aortic SLNs were located in the paracaval region in 66.6%, whereas pelvic SLNs were detected in 25.7% at the origin of the uterine artery and in 24.7% at the division of the common iliac artery. CONCLUSION A combination of radioactively labeled albumin with blue dye allows successful detection of SLN in patients with cervical cancer. The clinical validity of this technique must be evaluated prospectively.

Abstract
Sentinel lymph node (SLN) biopsy is a useful way of assessing axillary nodal status and obviating axillary lymph node dissection (ALND) in patients with node-negative breast cancer. Because SLN technology is evolving rapidly, however, variation in technique is widespread, and no standardization has yet been accomplished. This review discusses the feasibility and accuracy of this procedure and suggests the optimal method for identifying the SLN and detecting micrometastases. Although the SLN can be successfully identified by either the dye-guided or gamma probe-guided method in experienced hands, identification is facilitated when the two techniques are used together. In the gamma probe-guided method, the use of a large-sized radiotracer (particle size, 200-1000 nm) may be preferred because only one or two SLNs are identified. To increase the chance of finding metastases in SLN, it is desirable to make step sections with hematoxylin and eosin staining on permanent and frozen sections. The addition of immunohistochemistry may improve the accuracy of SLN diagnosis. The intraoperative examination of imprint cytology may be useful in determining the status of the SLNs, but further studies are needed to establish whether it has additional value when combined with the frozen section. In practice, routine ALND can be avoided when there is documentation of extensive experience and a low false-negative rate with the technique in the hands of a particular surgeon and hospital team. Particularly, SLN biopsy is more successful and has a lower false-negative rate in patients with smaller tumors. However, investigation of long-term regional control and survival in a prospective randomized trial is necessary, before SLN biopsy can replace routine ALND as the preferred staging operation for women with breast cancer.

Abstract
Pathological aspects of axillary nodal staging of breast cancer and in particular sentinel lymph node (SLN) biopsy are reviewed. SLN biopsy seems an almost ideal staging procedure because it has both high accuracy and a low false negative rate. It may also allow a cost effective use of more sensitive methods of metastasis detection. However, the biological relevance of metastases detected only by modern tools remains to be elucidated. This review focuses on standard axillary staging and the histopathological investigation of SLNs, with emphasis on the intraoperative setting. Future trends including ancillary studies, quality control issues, prediction of non-SLN involvement, and suggestions concerning the minimum requirements for the histology of axillary SLNs are also discussed.

Abstract
Several pilot studies have indicated that SLN biopsy can be used to identify axillary lymph node metastases in patients with breast cancer. To confirm this finding, a multicenter study in a variety of practice settings was performed. A total of 674 patients with breast cancer at five institutions were enrolled. The techniques of SLN identification included the vital dye-guided and the vital dye- and gamma probe-guided methods. The SLN was removed, and complete axillary lymph node dissection (ALND) was performed. SLN and ALND specimens were examined separately. The SLN was successfully identified in 214 (94%) of 227 patients using the combined dye- and gamma probe-guided methods. The SLN was identified in 332 (74%) of 447 patients using vital dye-guided method alone. Patient age of at least 21 years, medially located primary tumor, and clinically positive nodes were correlated with failure to identify the SLN. The accuracy of SLN biopsy for the detection of metastatic disease was 96% (522 of 546), and the sensitivity was 90% (203 of 226). Accuracy of 100% was achieved in the patients with tumors less than 1.6 cm in diameter. All 23 false negative results occurred with larger primary tumors. SLN biopsy can accurately predict the presence or absence of axillary lymph node metastases, particularly in patients with small (< or = 1.5 cm) breast cancers.

Abstract
One of the most important prognostic indicators in patients with breast cancer is axillary lymph node status. Sentinel lymph node (SLN) biopsy has emerged as a potential alternative to routine axillary dissection in clinically node-negative early breast cancer. This procedure requires a specialized but multidisciplinary approach utilizing the surgeon, nuclear radiologist and pathologist. SLN biopsy allows adequate assessment of the axillary nodal status in patients with early breast cancer, with minimal—if any—morbidity. Blue dye and lymphoscintigraphy are complementary techniques, and the success rate is maximized when the two methods are used together. Focused histopathologic examination on one or two lymph nodes most likely to contain metastases [SLN(s)], using serial sectioning and immunohistochemical techniques, allows an improved staging to be performed. Detection of metastases on SLN(s) is not only a prognostic indicator, but it also dictates whether the patient should receive further surgery and adjuvant chemotherapy. Until data regarding the long-term results of the SLN biopsy are available, this method should be considered investigational and be performed by surgeons experienced in this technique to achieve a failure rate of less than 2 per cent.

Abstract
BACKGROUND AND OBJECTIVES Sentinel lymph node (SLN) biopsy is not usually performed with respect to the internal mammary lymph node chain. However, the SLN may be located in the internal mammary chain, particularly with medial lesions. We carried out this study to investigate whether lymphatic mapping and SLN biopsy can detect internal mammary involvement in patients with breast cancer. METHODS A dye- and gamma probe-guided SLN biopsy was performed in a consecutive series of 41 patients with tumor in situ or clinical stage I or II breast cancer. After the biopsy, these patients underwent either a modified radical mastectomy or breast-conserving surgery including axillary lymph node dissection. Biopsy of internal mammary lymph nodes was performed in 19 of these patients. RESULTS No involvement of internal mammary lymph nodes was found histologically in 5 patients in whom lymphatic flow or a "hot nodule" in the internal mammary chain was found using lymphoscintigraphy. Nodal involvement was demonstrated histologically in only 1 of 5 cases where lymphatic vessels showed dye staining or faintly stained nodes. Internal mammary lymph node biopsy also was performed in 14 of 36 patients with neither stained lymphatic vessels or nodes, nor with lymphatic flow or a hot nodule by lymphoscintigraphy. Nodal involvement was found histologically in 1 of these patients. CONCLUSION SLN biopsy guided by lymphatic mapping is unreliable for identifying metastases to internal mammary lymph nodes.

Abstract
Seventy-two patients underwent dye-guided or dye- and gamma probe-guided sentinel lymphadenectomy (SLND) followed by complete axillary lymph node dissection (ALND). The results of imprint cytology, frozen sections, and permanent sections of the sentinel lymph node (SLN) were compared to each other and to the histologic findings in the nonsentinel nodes. The SLN was identified in 62 (88%) of 72 patients. Evaluation of the SLN on the permanent sections yielded a diagnostic accuracy of 95%, a sensitivity of 89%, and a specificity of 100%, although the reliability of SLN diagnosis using frozen sections or imprint cytology is limited. Therefore, it may be concluded that SLND with multiple sectioning and histopathologic examination of the SLNs can predict the presence or absence of axillary-node metastases in patients with breast cancer. However, further studies will be needed to investigate the value of SLND in respect to the long-term regional control and any possible detriment or benefit to survival, before it can replace routine ALND as the preferred staging operation for operable breast cancer.

Abstract
Sentinel lymphadenectomy is a useful way of assessing axillary status and obviating axillary dissection in patients with node-negative breast cancer. However, controversies remain concerning the optimal method to identify the sentinel lymph node (SLN) and detect micrometastases in this lymph node. We reviewed the literature concerning sentinel lymphadenectomy in breast cancer and reached the following conclusions: (a) A combination of preoperative lymphoscintigraphy with intraoperative dye-guided and gamma probe-guided methods achieves a higher rate of identification of SLN than any of these techniques alone. (b) Immediate and reliable intraoperative assessment of sentinel node status is vital to the technique's success. However, the reliability of sentinel node diagnosis using frozen sections is questionable, because micrometastatic foci cannot always be identified. (c) Hematoxylin and eosin (H&E) staining and/or immunohistochemistry on permanent sections are useful for the detection of micrometastases in the sentinel node. Although a reverse transcriptase-polymerase chain reaction (RT-PCR) method is more sensitive than H&E staining and immunohistochemistry, it would not distinguish benign from malignant epithelial cells in the SLN. Therefore, further study is required before sentinel lymphadenectomy gains general acceptance for patients with primary breast cancer.

Abstract
BACKGROUND: Sentinel lymphadenectomy has been used to assess the axillary nodal status in patients with breast cancer in an attempt to avoid unnecessary axillary dissection. Most studies have examined the utility of this procedure in clinically node-negative patients. However, the clinical evaluation of axillary nodes is often inaccurate for both clinically node-negative and clinically node-positive patients. METHODS: We performed dye-guided sentinel lymphadenectomy in both clinically node-negative and clinically node-positive patients with breast cancer. All patients also underwent a formal axillary dissection. The results of imprint cytology, frozen sections, and permanent sections of the sentinel lymph node (SLN) werecompared with each other and with histologic findings of the nonsentinel nodes. RESULTS: The SLN was identified in 30 (79%) of 38 patients with clinically negative nodes, and in 11 (92%) of 12 patients with clinically positive nodes. Forclinically node-negative patients, SLN evaluation yielded a diagnostic accuracyof 90%, a sensitivitiy of 72%, and a specificity of 100%. For clinically node-positive patients, these values were 100%, 100% and 100%, respectively. These values were not significantly different for the two groups of patients. CONCLUSION: Sentinel lymphadenectomy may be useful in assessing the axillarynodal status of both clinically node-positive and clinically node-negative breast cancer patients.

Before sentinel lymphadenectomy gains general acceptance for patients with primary breast cancer, however, a large clinical trial will be essential to verify the value of this technology.

Abstract
BACKGROUND Sentinel lymph node biopsy (SNB) in breast cancer may be used in place of axillary lymph node dissection (ALND) if SNB accurately stages the axilla. This study assessed the success and accuracy of axillary SNB with isosulfan blue (ISB) and technetium-99 sulfur colloid (TSC) compared to ALND. METHODS Forty-two women with T1 or T2 breast cancer underwent SNB and ALND. Sixty to 90 minutes before anesthetic induction, a mixture of 3 mL ISB and 1 mCi TSC was injected around the primary cancer or prior biopsy site. Intraoperatively, the SLN was identified using a gamma detector (Neoprobe 1000) or by visualization of the blue-stained lymph node and afferent lymphatics. The SLN was excised separately, and a level I/II ALND was completed. The histologic findings of the axillary contents and SLN were compared. RESULTS An axillary SLN was found in 38 of 42 (90%) cases. SLN localization rate and predictive value were the same for women who had and those who had not undergone excisional biopsy before the date of SNB. Fifteen of 42 (36%) patients had lymph node metastases. The SLN was positive in all women with axillary metastases (negative predictive value, 100%). CONCLUSIONS If confirmed by larger series, a negative SNB may eliminate the need for ALND for select women with breast cancer.

Abstract
Although it is generally accepted that axillary dissection provides no survival advantage in patients with breast cancer, it is commonly regarded as a reliable method of assessing nodal status and treating regional disease. However, it is time to consider eliminating routine axillary dissection in patients who are clinically node-negative. A sentinel lymph node biopsy may assess axillary nodal status while obviating a full axillary dissection. At present, axillary dissection remains the standard approach for the surgical management of all patients with invasive carcinoma of the breast, regardless of tumor size or patient age, though it is unnecessary for patients with small intraductal carcinomas.
