Abstract
Sentinel lymph node (SLN) mapping in patients with breast cancer treated with neoadjuvant chemotherapy has been debated by surgeons as a result of potential compromise of lymphatic drainage. Whether clinicopathologic variables traditionally associated with SLN positivity differ in patients who have been treated with neoadjuvant chemotherapy has not been well studied. Patients diagnosed with breast carcinoma who underwent neoadjuvant chemotherapy, definitive breast surgery, sentinel node biopsy (SNB), and axillary lymph node dissection (ALND) were retrospectively identified over a 75-month period. Clinicopathologic parameters including age, clinical tumor and node stage, neoadjuvant chemotherapy regimen, pathological tumor and node stage, lymphovascular invasion (LVI), SLN and non-SLN involvement, and extranodal extension were recorded. Ninety-seven patients met inclusion criteria. Ninety-eight per cent had successful SLN mapping. Eight patients with negative SLNs had positive ALND (false-negative rate, 8.3%). Clinicopathological variables associated with SLN status included clinical axillary status ( P = 0.038), pathologic tumor size, and nodal status and LVI ( P < 0.001). Extranodal extension was significantly associated with non-SLN status ( P = 0.004). In patients achieving a pathologic complete response (PCR), SNB remained feasible and accurate (false-negative rate, 11.6%). Successful SLN mapping in patients who have undergone neoadjuvant chemotherapy is highly accurate with a low false-negative rate even in patients who have a PCR.

Abstract
Introduction Sentinel lymph node (SLN) biopsy is the gold standard for surgical staging of the axilla in breast cancer (BC). Frozen section (FS) remains the most popular means of intraoperative SLN diagnosis. Imprint cytology (IC) has also been suggested as a less expensive and equally accurate alternative to FS. The aim of our study was to perform a direct comparison between IC and FS on the same SLNs of BC cases operated in a single center by the same surgical team. Materials and methods Into this prospective study we enrolled 60 consecutive patients with histologically proven T1–T3 BC and clinically negative axilla. Sentinel nodes were detected using a standard protocol. The SLN(s) was always assessed by IC as well as FS analysis and immunohistochemistry. Nevertheless, all intraoperative decisions were based on FS analysis. Results During the study period 60 patients with invasive BC were registered, with 80 SLNs harvested. Mean number of SLN(s) identified for each patient was 1.33. The sensitivity and specificity were 90% and 100%, respectively, for IC, and 80% and 100% for FS. Relevant positive/negative predictive values were 100%/98% for IC and 100%/96.15%, respectively, for FS. Overall accuracy was 98% for IC and 97% for FS. Therefore, statistically significant difference between the two methods in the detection of positive nodes was not elucidated (p=1.000). Conclusions IC appeared to be marginally more sensitive than FS in detecting SLN metastatic activity. Overall accuracy was 98.75%. With regard to the primary lesion characteristics, we conclude that initial lesion size and lymphovascular invasion play a pivotal role in metastatic involvement of the SLN with the dimensions of metastasis bearing no correlation with tumor size. Therefore, IC appears to be a sensitive and accurate method for the intraoperative assessment of SLN in BC patients, but further studies are required to confirm this interesting data.

Abstract
BACKGROUND Historical studies of lymphatic drainage of the breast have suggested that the lymphatic drainage of the breast was to lymph nodes lying in the antero-pectoral group of nodes in the axilla just lateral to the pectoral muscles. The purpose of this study was to confirm this is not correct. METHODS The hybrid imaging method of SPECT/CT allows the exact anatomical position of the sentinel lymph node (SLN) in the axilla to be documented during pre-operative lymphoscintigraphy (LS) in patients with breast cancer. We have done this in a series of 741 patients. The Level I axillary nodes were defined as anterior, mid or posterior. This was related to the anatomical location of the primary cancer in the breast. RESULTS A SLN was found in the axilla in 97.8% of our patients. Just under 50% of SLNs located in the axilla were not in the anterior group and lay in the mid or posterior group of Level I axillary nodes. There was a SLN in a single node field in 460 patients (63%), two node fields in 261(36%), three node fields in 6 and four node fields in 1 patient. CONCLUSION Axillary lymphatic drainage from the breast is not exclusively to the anterior (or antero-pectoral) group of Level I nodes. SYNOPSIS SPECT/CT lymphoscintigraphy shows that the breast does not always drain to the anterior group of Level I lymph nodes in the axilla but may drain to the mid axilla and/or posterior group in about 50% of patients with breast cancer regardless of the location of the cancer in the breast. These data redefine lymph drainage from the breast to axillary lymph nodes.

Abstract
The development and acceptance of the SLND has profoundly affected the management of breast cancer. SLND has supplanted ALND as a highly accurate and less-morbid axillary staging procedure in patients with clinically node-negative early-stage breast cancer. SLND alone is associated with less than 1% isolated axillary recurrence in patients with node-negative disease and provides excellent regional nodal control. Historically, ALND has been the recommended treatment for patients with SLN metastases. ALND was thought to offer prognostic information, prevent axillary local recurrence, and possibly render a small survival benefit. However, resection of nonsentinel nodes with metastases may not affect survival, and not all axillary metastases progress to become clinically evident. Furthermore, with increased understanding of tumor biology, nodal status and number of involved lymph nodes are no longer the only determinants of systemic therapy. As improved breast cancer screening allows identification of early-stage disease localized to the breast, and because treatment plans are more often made on the basis of tumor biology, the role of completion ALND may be less critical. The low LRR rates seen in the ACOSOG Z0011 trial, several other randomized trials, and retrospective reviews suggest that SLND alone may provide adequate locoregional control and provide adequate information to guide adjuvant systemic therapy in selected women with clinically node-negative early-stage breast cancer.

Abstract
BACKGROUND Breast cancer treatment beliefs in areas of scientific uncertainty may contribute to widely variable practices. We sought to better describe surgeons' beliefs and to identify the relative importance of different information sources on surgeons' decision-making. METHODS A total of 2,188 American College of Surgeons (ACoS) members were surveyed on their treatment beliefs in 4 controversial areas and on the perceived influence of various information sources on their decision-making. Responses were analyzed by sex, practice type, oncology training, professional society membership, and breast cancer patient volume. RESULTS Nine hundred twenty-three responses were received, with 459 eligible for analysis. Responses diverged most regarding significance of positive sentinel lymph node biopsy (SNLB) and role of post-lumpectomy radiation for low-risk ductal carcinoma-in-situ (DCIS). Overall, expert opinion ranked as the most influential information source. CONCLUSIONS Axillary dissection after positive SLNB and post-lumpectomy radiation in low-risk DCIS denoted areas of greater uncertainty. Breast cancer opinion leaders have substantial influence when standard practice is uncertain.

Abstract
BACKGROUND The timing and accuracy of axillary sentinel lymph node biopsy (SLNB) in patients who are receiving neoadjuvant chemotherapy (NACT) for breast cancer are controversial. To examine the accuracy of SLNB after NACT, the authors performed SLNB after chemotherapy on all of patients who received NACT at their institution starting in January 1997. METHODS Seventy-nine women who underwent NACT between 1997 and 2008 comprised this study and were divided as follows: 4 women had stage I disease, 60 women had stage II disease, and 15 women had stage III disease, including 10 women who had multicentric disease. Thirty-nine women (49.4%) had clinical evidence of axillary metastasis (N1-N2) at the time of diagnosis. The regimen, the duration of treatment, and the number of cycles of NACT depended on clinical response. The choice of breast conservation therapy or mastectomy was based on the patient's response to treatment and patient preference. All patients underwent SLNB after NACT. RESULTS Seventy-three patients underwent breast conservation therapy, and 6 patients underwent mastectomy. Sentinel lymph nodes were identified in 98.7% of patients (in 1 patient, SLNB failed to capture 1 proven axillary metastasis), and 29 patients underwent full axillary lymph node dissection. Fourteen patients (17.7%) had no residual carcinoma (invasive or ductal carcinoma in situ) in their breast, 5 patients (6.3%) had residual ductal carcinoma in situ (only), and 60 patients (75.9%) had residual invasive carcinoma. One false-negative SLNB was reported in the group of 23 patients who underwent full axillary dissection after a negative SLNB. No patient had a subsequent axillary recurrence. CONCLUSIONS SLNB after NACT was feasible in virtually all patients and accurately selected patients who required complete level I and II axillary dissection. NACT frequently downstaged the axilla, converting patients with N1-N2 lymph node status to N0 status and also avoiding full axillary dissection in these patients.

Abstract
The axillary lymph node status is the most reliable prognostic indicator of recurrence and overall survival in patients with breast cancer. The current standard surgical procedure for the management of invasive breast cancer is the complete removal of the cancer with total axillary clearance. However, recently, selective sentinel lymph node mapping and biopsy is gaining acceptance as a useful and accurate staging procedure, as it is minimally invasive. The sentinel lymph node is the first node into which a primary cancer drains, and is thus the first node to be involved by metastases. Patients whose sentinel nodes are negative for breast cancer metastases, can be spared a more extensive axillary lymph node dissection, with reduction in the postoperative morbidity. Sentinel node mapping is usually performed by intradermal or peritumoral injection of a combination of blue dye and radiotracer. Sentinel node examination is sometimes done intraoperatively, by imprint cytology and frozen sections, for an immediate assessment, to plan the extent of surgery at a single sitting. Permanent sections of the sentinel node are studied by serial sectioning, and immunohistochemistry for cytokeratin is done to detect micrometastases which are frequently missed on hematoxylin and eosin (H&E)-stained sections. The various aspects of sentinel node examination, and its role to decide further management in patients with ductal carcinoma-in-situ, and in other clinical settings, are discussed in this review.

Abstract
The aim of this study was to develop and evaluate 111In- and 99mTc-labeled derivatives of albumin nanocolloid (NC) for dual-label lymphoscintigraphy to allow simultaneous comparison of lymphatic flow from different tissue planes draining a tumour bed for accurate identification of sentinel lymph nodes (SLN). Using the chelator, p-isothiocyanatobenzyl-1,4,7, 10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA), 111In-DOTA-NC and 99mTc-DOTA-NC were compared in vitro with respect to stability of labeling, colloidal status and particle size, then in vivo by measuring their clearance rates from a subcutaneous injection depot. 111In-DOTA-NC and 99mTc-DOTA-NC were indistinguishable on the basis of in vitro criteria. Their in vivo clearance rates, however, were disparate (0.0015 to 0.075 min(-1) for 111In and 0.0072 to 0.067 min(-1) for 99mTc), 111In being faster in three studies and markedly slower in three. This demonstrates that even when dual-labeled radiotracers behave identically in vitro, they will not necessarily do so in vivo. Further work is needed to develop dual-labeled NC.

Abstract
AIMS The objective of this study was to assess the value of superficial (intradermal) and paratumoral (above the tumor) (ID) injection of labeled colloids for imaging sentinel lymph nodes (SLN) as a rescue technique in breast cancer patients for whom deep (intraparenchymatous) and peritumoral (around the tumor) (IP) injections had failed. METHODS We assessed data from 2 groups of women: 469 women for whom IP injections successfully visualized a SLN (IP-only) and 52 women for whom IP injections were unsuccessful and ID injection was performed (IP0-ID). Patient characteristics and SLN results were compared. RESULTS Most characteristics of the two patients series were similar. However, IP0-ID patients were on average 10years older than the IP-only patients and had more grade-III tumors. The false negative rate (FNR) for the IP0-ID patients (9/25, 23.8%) was significantly higher than for the IP-only patients (12/240, 5%; p<0.01) and for a subgroup of IP-only patients older than 50 years (8/159, 5%; p=0.009). Four of five false negatives in the IP0-ID group involved a tumor in the outer quadrants. The FNR for cases with external tumors was 33% for the IP0-ID patients, a percentage significantly higher than the corresponding values for the IP-only patients (5.8%) and for the IP-only patients older than 50 years (5.7%). CONCLUSION In patients with unsuccessful deep IP injections, superficial ID injections lead to a high percentage of false negative SLN conclusions, merely when tumours were located in the outer quadrants. Thus, it is recommended that patients with unsuccessful intra-parenchymatous and peritumoral injections of radiocolloids for tumors in outer quadrants undergo complete axillary dissection.

Abstract
Background Current understanding of the lymphatic system of the breast is derived mainly from the work of the anatomist Sappey in the 1850s, with many observations made during the development and introduction of breast lymphatic mapping and sentinel node biopsy contributing to our knowledge. Methods Twenty four breasts in 14 fresh human cadavers (5 male, 9 female) were studied. Lymph vessels were identified with hydrogen peroxide and injected with a lead oxide mixture and radiographed. The specimens were cross sectioned and radiographed to provide three dimensional images. Lymph (collecting) vessels were traced from the periphery to the first-tier lymph node. Results Lymph collecting vessels were found evenly spaced at the periphery of the anterior upper torso draining radially into the axillary lymph nodes. As they reached the breast some passed over and some through the breast parenchyma, as revealed in the cross-section studies. The pathways showed no significant difference between male and female specimens. We found also perforating lymph vessels that coursed beside the branches of the internal mammary vessels, draining into the ipsilateral internal mammary lymphatics. In some studies one sentinel node in the axilla drained almost the entire breast. In most more than one sentinel node was represented. Conclusion These anatomical findings are discordant with our current knowledge based on previous studies and demand closer examination by clinicians. These anatomical studies may help explain the percentage of false-negative sentinel node biopsy studies and suggest the peritumoral injection site for accurate sentinel lymph node detection.

Abstract
The authors compare the detection of metastases in sentinel lymph nodes (SLNs) and nonsentinel lymph nodes (NSLNs) using hematoxylin-eosin (HE) staining versus immunohistochemistry (IHC). Thirty-six patients with breast carcinoma undergo exeresis of the primary tumor and of 50 SLNs and 491 NSLNs. Sentinel lymph nodes are sectioned into transverse slices of 2- to 3-mm thickness, and a cytologic smear and a frozen section were obtained from each slice. The slices are completely cut into serial sections at 100-microm intervals. Two consecutive 4-microm-thick sections are then obtained from each level and were prepared for HE staining and IHC. Nonsentinel lymph nodes are evaluated similarly to SLNs. The authors obtain 4076 SLN sections and 32 012 NSLN sections, for a total of 36 088 sections. A comparison of HE staining versus IHC based on the total number of sections shows a sensitivity of 93.8%, a negative predictive value of 98.9%, and an accuracy of 99.1%. The values obtained by HE staining are similar to those obtained by IHC.

Abstract
The tumor status of the axillary lymph nodes is the single most important predictor of survival for patients with primary breast cancer. Because of its essential role in staging, regional control, and perhaps survival, axillary lymph node dissection (ALND) has long been the standard of care for patients with operable breast cancer. During the past decade, the introduction and development of sentinel lymph node dissection (SLND) for primary breast cancer have allowed surgeons to determine the tumor status of the axilla without a standard level I and II ALND. Several well-designed studies have documented that SLND is an effective way of assessing axillary nodal status with minimal morbidity and high accuracy. We address the current status and future directions of SLND for primary breast cancer.

Abstract
BACKGROUND The role of sentinel lymph node biopsy (SLNB) for ductal carcinoma in situ (DCIS) is poorly defined. However, up to 20% of patients with DCIS will have invasive carcinoma; these patients require staging for axillary metastasis. The aim of this study was to identify patients with a core biopsy diagnosis of DCIS who may benefit from SLNB. METHODS In a prospective study, we performed SLNB on patients with a preoperative diagnosis of >2.5 cm of high-grade DCIS or DCIS when mastectomy was indicated. RESULTS Sixty-two patients underwent surgery for high-grade DCIS, and 35 of these patients underwent SLNB. Postsurgical excision histology revealed invasive disease in 20 patients, 19 of whom had undergone SLNB. Before the adoption of SLNB in selected DCIS patients, all 20 with occult invasive disease would have required second surgery axillary staging (P < .01, chi-square test). CONCLUSIONS SLNB should not be performed routinely for all patients with an initial diagnosis of DCIS. However, selective lymphadenectomy may be a useful clinical adjuvant in selected high-risk DCIS patients.

Abstract
We investigated the increased incidence of early-stage breast cancer with micrometastatic lymph node involvement. Breast cancer incidence trends from 1990 through 2002 in the US Surveillance, Epidemiology, and End Results Program catchment area were analyzed. Joinpoint regression was used to show the annual percentage change (APC) in breast cancer incidence trends. The overall incidence of breast cancer among women aged 50-64 years increased 1.8% (95% confidence interval [CI] = 1.4% to 2.2%) per annum from 1990 through 2002 but decreased in all other age groups. Stage IIA and stage IIB tumor incidence increased (APC for stage IIA from 1996 to 2002 = 61.9%, 95% CI = 51.1% to 73.4%, and APC for stage IIB from 1998 to 2002 = 53.7%, 95% CI = 20.6% to 96.0%). The incidence of micrometastatic lymph node involvement for stage IIA and stage IIB tumors increased during the 1990s, especially after 1997 (APC = 17.3% for both stages), more for estrogen receptor-positive than estrogen receptor-negative disease. Increased use of mammography screening partly explains the increased incidence of early-stage breast cancer. Increases in small tumors with micrometastatic lymph node involvement may be attributable to the increased use of the sentinel lymph node biopsy in community practice.

Abstract
Sentinel lymph node biopsy (SLNB) has been developed as a new diagnostic and therapeutic modality in melanoma and breast cancer surgery. The purpose of the SLNB include preventing the operative morbidity and improving the pathologic stage by focusing on fewer lymph nodes using immunocytochemic and molecular technology has almost achieved in breast cancer surgery. The prognostic meaning of immunocytochemically detected micrometastases is also evaluating in the SLN and bone marrow aspirates of women with early-stage breast cancer. SLNB using available techniques have suggested that the lymphatic drainage of the gastrointestinal tract is much more complicated than other sites, skip metastasis being rather frequent because of an aberrant lymphatic drainage outside of the basin exist. At the moment, the available data does not justify reduced extent of lymphadenectomy, but provides strong evidence for an improvement in tumor staging on the basis of SLNB. Two large scale prospective multi-center trials concerning feasibility of gamma-probe and dye detection for gastric cancer are ongoing in Japan. Recent studies have shown favorable results for identification of SLN in esophageal cancer. CT lymphography with endoscopic mucosal injection of iopamidol was applicable for SLN navigation of superficial esophageal cancer. The aim of surgical treatment is complete resection of the tumor-infiltrated organ including the regional lymph nodes. Accurate detection of SLN can achieve a selection of a more sophisticated tailor made approach. The patient can make a individualized choice from a broader spectrum of therapeutic options including endoscopic, laparoscopic or laparoscopy-assisted surgery, modified radical surgery, and typical radical surgery with lymph node dissection. Ultrastaging by detecting micrometastasis at the molecular level and the choice of an adequate treatment improve the postoperative quality of life and survival. However these issues require further investigation.

Abstract
Sentinel lymph node biopsy (SLNB) has replaced the routine level I and II axillary lymph node dissection (ALND) for women with clinically node-negative T1 and T2 breast cancer. Studies have shown that SLNB is highly predictive of axillary nodal status with a false-negative of rate less than 10%. Our purpose was to address some of the ongoing controversies about this procedure, including technical issues, use of preoperative lymphoscintigraphy, internal mammary lymph node biopsy, criteria for patient selection (in intraductal carcinoma?), its staging accuracy, and the clinical approach when a SLNB was found to be negative or positive on pathologic examination. After the revision of the American Joint Committee on Cancer (AJCC) staging system for breast cancer in 2002, the evaluation of internal mammary lymph nodes and determination of micrometastases by hematoxylin-eosin or by immunohistochemistry have become increasingly important in staging of patients. Recent guideline recommendations developed by the American Society of Clinical Oncology (ASCO) Expert Panel in 2005 are also discussed. Long-term follow-up results of ongoing studies will provide more accurate assessment of the prognostic significance of SLNB and its value in the prevention of breast cancer-related morbidity in axillary staging compared to ALND.

Abstract
Prognostic factors are used to help clinical decision-making in selecting the appropriate treatment for individual patients. The purpose of this retrospective study was to identify one or more factors associated with overall survival (OS) and disease-free survival (DFS), in 710 patients with operable breast cancer, subjected to neoadjuvant chemotherapy followed by surgery, radiotherapy and adjuvant treatments. At a median follow-up of 7.6 years, univariate analysis showed that pathological complete response (pCR) was significantly related to survival (p < 0.003), as well as accepted prognostic factors, as SBR and MSBR grades, hormonal receptors or node involvement at surgery, who remained significant in our study (p < 0.001). The revised Nottingham prognostic index (NPI) and related indices (BGI, MNPI and MBGI) were also significantly associated to survival (p < 0.003). In multivariate analysis, node involvement and MSBR grade remained prognostic factors for OS and DFS (p < 0.0003 and p < 0.02, respectively). The MNPI and pCR were significantly related with OS (p = 0.04) and pts with hormonal receptor-positive tumours had a better DFS than others (p = 0.004). Among all clinical and pathological parameters, axillary dissection after neoadjuvant chemotherapy is still important to determine node involvement, a major prognostic factor. Moreover, MSBR grade seemed to be more accurate and predictive of long-term outcome than the standard SBR grade. It is concluded that, outside any other 'biological' factor, residual disease in breast and nodes must be strongly considered after an induction chemotherapy so as to choose adjuvant treatment for the individual patient.

Abstract
The sentinel lymph node (SLN) is the only focus of axillary metastasis in a significant proportion of patients. In this single institutional study, clinicopathologic characteristics were investigated to determine the factors predicting the status of a SLN biopsy and the metastatic involvement of non-SLNs. Data were retrospectively reveiwed for 400 consecutive patients with clinical T1/T2 N0 breast cancer who underwent a SLN biopsy including axillary and/or internal mammary lymph nodes. The SLNs were evaluated by using the new AJCC staging criteria following multiple sectioning and immunohistochemical (IHC) analyses of nodes. The SLN contained metastases in 148 patients (38.5%) including 18 patients (12.2%) with micrometastases (<or=0.2 mm) and 130 patients (87.8%) with macrometastases (>0.2 cm). Five patients had isolated tumor cells detected by IHC (<or=0.2 mm, N(0i)). Patients with tumor size more than 2 cm (T1, 29.8% versus T2, 51.6%; OR=2.31, 95% CI, 1.50-3.56) and lymphovascular invasion (LVI-, 30.3% versus LVI+, 51.3%; OR=2.07, 95% CI, 1.34-3.19) were more likely to have positive SLNs in both univariate and multivariate analyses. Among patients with a positive SLN biopsy, those with T2 tumors (versus T1; 63.1% versus 36.9; OR=2.93, 95% CI, 1.43-6.04), macrometastases in SLNs (versus micrometastases; 88.9% versus 11.1%; OR=8.83; 95% CI, 1.82-42.87) and extracapsular node extension (versus without extracapsular node extension; 65.4% versus 34.6%; OR, 2.23; 95% CI, 1.05-4.72) were more likely to have non-SLN metastases in both univariate and multivarite analyses. These results indicate that clinicopathologic factors might be helpful to select patients who were less likely to have negative SLN or non-SLNs. However, additional factors are still needed to be identified to omit surgical axillary staging.

Abstract
AIM To review the role of sentinel lymph node (SLN) biopsy in the surgical management of patients with ductal carcinoma in situ (DCIS). METHODS A search was conducted of Medline and the National Library of Medicine to identify key articles concerning DCIS, SLN biopsy (SLNB) and axillary dissection. Further relevant articles were obtained from the references cited in the literature. RESULTS Up to 20% of patients with a core biopsy diagnosis of DCIS will be later up-staged based on an invasive component identified on the excision specimen. Quality assurance in breast screening programmes requires minimally invasive pre-operative diagnosis and also axillary sampling in the case of documented invasive disease. As an effective and validated procedure, SLNB represents a paradigm shift in the surgical management of the axilla for patients with invasive breast cancer. It remains undefined which, if any, subgroups of patients with DCIS should undergo SLNB. CONCLUSION Axillary lymphadenectomy is an overtreatment for patients with DCIS. Performing a SLNB during the initial procedure may avoid a second operation in some DCIS patients who are diagnosed with occult invasive disease at their definitive operation. When predictors of hidden invasive disease are clarified by further study, SLNB may be used in the management of selected high-risk DCIS patients.

Abstract
OBJECTIVE Sentinel lymph node (SLN) biopsy is a new component of the surgical treatment of breast cancer that accurately predicts axillary status. In this study the authors evaluated the accuracy of intraoperative imprint cytology (IC) in comparison with definitive histologic evaluation of SLN in breast cancer patients. METHODS A total 413 women with breast carcinoma and clinically negative axillary nodes underwent breast surgery and SLN biopsy. Mapping of SLN involved injection of (99m)Technecium labelled human albumin nanocolloid particles and Patent Blue dye. At the Department of Pathology, SLNs were bisected along its major axis. Both halves were imprinted 2-4 times on the slides and immediate staining with Hemacolor (Merck Germany) was performed for intraoperative examination. Imprint node negative women underwent no further surgery, while node positive women proceeded to full axillary clearance. Histological analysis of the SLN involved serial sectioning of the whole node with H&E and immunostaining for cytokeratin. RESULTS Definitive histology revealed metastases (pN+) in 159/413 patients (38.5%): 69 (16.7%) macro metastases, 57 (13.8%) micro metastases, and 33 (8%) women with only isolated IHC positive cells or positive cell groups smaller than 0.2 mm (pNO sn+). The other 254 women had negative SLN biopsy. Imprint cytology detected 54/69 macro metastases, and 4/57 micro metastases. In the group with negative SLN (254), 2 cases were ''false positives''. CONCLUSIONS Imprint of SLN biopsy can identify a negative axilla with high accuracy (specificity 99.2%). Overall sensitivity is only 36.5%, but macrometastases are detected in 77% which is important for performing ALDN in one session with operation of primary tumour.
