Absence of post-treatment changes in sentinel lymph nodes does not translate into increased regional recurrence rate in initially node-positive breast cancer patients. Breast Cancer Res Treat 2023; 202:443-450. [PMID: 37679645 PMCID: PMC10564834 DOI: 10.1007/s10549-023-07084-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Accepted: 08/10/2023] [Indexed: 09/09/2023]
Abstract
PURPOSE To determine whether the absence of post-treatment changes in the negative sentinel lymph nodes (SLN) in the neoadjuvant setting for biopsy-proven cN + disease results in an increased regional recurrence (RR) rate in patients after SLN biopsy (SLNB) only. METHODS Breast cancer patients with biopsy-proven cN + disease who converted to node-negative disease after neoadjuvant systemic treatment (NAST) and underwent SLNB only were included. Retrospective analysis was performed for patients diagnosed between 2008 and 2021. Pathohistological specimens were reviewed for the presence of post-treatment changes in the SLNs. Patients with negative SLNs (ypN0) were divided into two groups: (i) with post-treatment changes, (ii) without post-treatment changes. Patients' characteristics were compared between groups. Crude RR rates were compared using the log-rank test. Recurrence-free (RFS) and overall survival (OS) for the entire cohort were calculated using Kaplan-Meier. RESULTS Of 437 patients with cN + disease, 95 underwent SLNB only. 82 were ypN0, 57 with post-treatment changes (group 1), 25 without post-treatment changes (group 2). During the median follow-up of 37 months (range 6-148), 1 isolated regional recurrence occurred in group 2 (RR rate 0% for group 1 vs. 4% for group 2, p = 0.149). There were no differences in 3-year RFS and OS between groups. CONCLUSION Absent post-treatment changes in negative SLNs for biopsy-proven cN + disease that covert to node-negative after NAST did not result in increased regional recurrence rates in our cohort. Multidisciplinary input is essential to determine whether additional treatment is needed in these patients.

Abstract
Neoadjuvant chemotherapy (NACT) has become the standard of care for high-risk breast cancer, including triple-negative (TNBC) and HER2-positive disease. As a result, handling and reporting of breast specimens post-NACT is part of routine practice, and it is important for pathologists to recognise the changes in tumour cells, tumour-associated stroma and background breast tissue induced by NACT. Familiarity with characteristic stromal features enables identification of the pre-treatment tumour site and allows confident diagnosis of pathological complete response (pCR) which is important for decisions concerning adjuvant therapy. Neoadjuvant endocrine therapy (NAET) is used less frequently than NACT; however, the SARS-COVID-19 pandemic has changed practice, with increased use as bridging therapy if surgery is delayed. NAET also induces characteristic changes in the tumour and stroma. Changes in the tumour microenvironment following NACT and NAET are also described. Immunotherapy is approved for use in advanced TNBC, and there are several trials exploring its role in early TNBC in the neoadjuvant setting. The current biomarker to determine eligibility for treatment with immune checkpoint inhibitors is programmed death ligand-1 (PD-L1) immunohistochemistry; however, this is complicated by lack of standardisation with different drugs linked to tests using different antibodies with different scoring systems. The situation in the neoadjuvant setting is further complicated by improved pCR rates for PD-L1-positive tumours in both immune therapy and placebo arms. Alternative biomarkers are urgently needed to identify which patients will derive benefit from immunotherapy and key candidates are discussed.

False-negative rate in the extended prospective TATTOO trial evaluating targeted axillary dissection by carbon tattooing in clinically node-positive breast cancer patients receiving neoadjuvant systemic therapy. Breast Cancer Res Treat 2022; 193:589-595. [PMID: 35451733 PMCID: PMC9114094 DOI: 10.1007/s10549-022-06588-2] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Accepted: 03/27/2022] [Indexed: 11/27/2022]
Abstract
PURPOSE In clinically node-positive breast cancer patients receiving neoadjuvant systemic therapy (NST), nodal metastases can be initially marked and then removed during surgical axillary staging. Marking methods vary significantly in terms of feasibility and cost. The purpose of the extended TATTOO trial was to report on the false-negative rate (FNR) of the low-cost method carbon tattooing. METHODS The international prospective single-arm TATTOO trial included clinically node-positive breast cancer patients planned for NST from November 2017 to January 2021. For the present analysis, patients who received both the targeted procedure with or without an additional sentinel lymph node (SLN) biopsy and a completion axillary lymph node dissection (ALND) were selected. Primary endpoint was the FNR. RESULTS Out of 172 included patients, 149 had undergone a completion ALND. The detection rate for the tattooed node was 94.6% (141 out of 149). SLN biopsy was attempted in 132 out of 149 patients with a detection rate of 91.7% (121 out of 132). SLN and tattooed node were identical in 58 out of 121 individuals (47.9%). The combined procedure, i.e. targeted axillary dissection (TAD) was successful in 147 of 149 cases (98.7%). Four out of 65 patients with a clinically node-negative status after NST had a negative TAD but metastases on ALND, corresponding to a FNR of 6.2%. All false-negative TAD procedures were performed in the first 2 years of the trial (2018-2019, p = 0.022). CONCLUSION Carbon tattooing is a feasible marking method for TAD with a high detection rate and an acceptably low FNR. The TATTOO trial was preregistered as prospective trial before initiation at the University of Rostock, Germany (DRKS00013169).

Abstract
Our understanding of the cellular composition and architecture of cancer has primarily advanced using 2D models and thin slice samples. This has granted spatial information on fundamental cancer biology and treatment response. However, tissues contain a variety of interconnected cells with different functional states and shapes, and this complex organization is impossible to capture in a single plane. Furthermore, tumours have been shown to be highly heterogenous, requiring large-scale spatial analysis to reliably profile their cellular and structural composition. Volumetric imaging permits the visualization of intact biological samples, thereby revealing the spatio-phenotypic and dynamic traits of cancer. This review focuses on new insights into cancer biology uniquely brought to light by 3D imaging and concomitant progress in cancer modelling and quantitative analysis. 3D imaging has the potential to generate broad knowledge advance from major mechanisms of tumour progression to new strategies for cancer treatment and patient diagnosis. We discuss the expected future contributions of the newest imaging trends towards these goals and the challenges faced for reaching their full application in cancer research.

Abstract
BACKGROUND Evidence on the accuracy of sentinel lymph node biopsy (SLNB) after neoadjuvant therapy (NAT) for patients with breast cancer is inconclusive. This study reviewed the real-world data to determine the acceptability of SLNB after NAT. METHODS The study searched for articles in the PubMed, EMBASE, and Cochrane Library databases. The primary outcomes were the identification rate for sentinel lymph nodes (SLNs) and the false-negative rate (FNR) for SLNB. The study also evaluated the FNR in subgroups defined by tumor stage, nodal stage, hormone receptor status, human epidermal growth factor receptor-2 status, tumor response, mapping technique, and number of SLNs removed. RESULTS The study retrieved 61 prospective and 18 retrospective studies with 10,680 initially cN± patients. The pooled estimate of the identification rate was 0.906 (95 % confidence interval [CI], 0.891-0.922), and the pooled FNR was 0.118 (95 % CI, 0.103-0.133). In subgroup analysis, the FNR was significantly higher for the patients with estrogen receptor (ER)-negative status and fewer than three SLNs removed. The FNR did not differ significantly between the patients with and those without complete tumor response. Among the patients with initial clinical negative axillary lymph nodes, the incidence of node metastasis was 26.8 % (275/1041) after NAT. CONCLUSION Real-world evidence indicates that the FNR of SLNB after NAT in breast cancer is 11.8 %, exceeding only slightly the commonly adopted threshold of 10 %. The FNR is significantly higher for patients with ER-negative status and removal of fewer than three SLNs. Using a dual tracer and removing at least three SLNs may increase the accuracy of SLNB after NAT.

Abstract
Context Telepathology is a digital, microscope-independent method of diagnosing pathology from scanned slides. Frozen sections (FS) can be performed and read by a pathologist at any site. At our institution, telepathology is used for diagnosis of frozen sections of sentinel lymph nodes (SLN) in patients who have undergone neoadjuvant chemotherapy and are enrolled in a clinical trial. Objective We investigated the accuracy of diagnosing SLN frozen sections in the neoadjuvant setting using telepathology. Design SLN were entirely submitted for frozen section. A pathology assistant prepared the frozen and scanned the slides using VisionTek M6 digital microscope ecosystem (East Dundee, IL). Cases were interpreted by trained, board-certified pathologists. All frozen sections remnants were submitted for formalin-fixed paraffin-embedded permanent sections. Frozen section diagnoses using telepathology were compared to final pathology. Turn-around time from specimen collection to frozen section diagnosis was recorded. Results 54 SLN from 22 breast neoadjuvant cases were diagnosed via telepathology from March 2017 to July 2019. 95% of SLNs interpreted as negative on frozen section and on permanents. A definitive diagnosis could not be rendered on six SLNs; diagnosed “atypical” at frozen. Sensitivity and specificity were 80% and 100% respectively with accuracy of 95.8%. The false-negative rate was 5%. There were no false positives. The average turn-around time was over an hour. Conclusions Telepathology is an accurate method of diagnosing SLN frozen sections in the neoadjuvant setting, but lobular carcinomas and treatment effect pose diagnostic challenges and the time to report results is increased compared to standard microscopy.

Abstract
BACKGROUND Nodal status evaluation is a crucial step in determining prognostic factors and managing treatment strategies for breast cancer patients. Preoperative (CNB), intraoperative (SLNB), and even postoperative techniques (Formalin-Fixed Paraffin-Embedded sectioning, FFPE) have definite limitations of precision or sometimes are time-consuming for the result declaration. The primary purpose of this prospective study is to provide a precise complementary system for distinguishing lymph nodes (LNs) involved by cancerous cells in breast cancer patients intraoperatively. METHODS The proposed system, Electrical Lymph Scoring(ELS), is designed based on the dielectric properties of the under-test LNs. The system has a needle-shaped 2-electrode probe entered into SLNs or ALNs dissected from patients through standard surgical guidelines. Impedance magnitude in f = 1 kH (Z1kHz) and Impedance Phase Slope in frequency ranges of 100 kHz-500 kHz (IPS) were then extracted from the impedance spectroscopy data in a cohort study of 77 breast cancer patients(totally 282 dissected LNs) who had been undergone surgery before (n = 55) or after (n = 22) chemical therapies (non-neoadjuvant or neoadjuvant chemotherapy). A new admittance parameter(Yn') also proposed for LN detection in neoadjuvant chemotherapy patients. RESULTS Considering the permanent pathology result as the gold standard checked by two independent expert pathologists, a significant correlation was observed between the presence of cancerous cells in LNs and individual ranges of the ELS electrical responses. Compared with normal LNs containing fatty ambient and immune cells, LNs involved by cancerous clusters would reduce the Z1kHz and increase the IPS. These changes correlate with fat metabolism by cancer cells due to their Fatty Acid Oxidation (FAO) in LN, which results in different dielectric properties between high and low-fat content of normal and cancerous LNs, respectively. CONCLUSIONS By finding the best correlation between our defined impedimetric parameters and pathological states of tested LNs, a real-time intraoperative detection approach was developed for highly-sensitive (92%, P<0.001) diagnosis of involved sentinel or axillary LNs. The impact of real-time intraoperative scoring of SLNs would make a pre-estimation about the necessity of excising further LNs to help the surgeon for less invasive surgery, especially in the absence of frozen-section equipment.

Abstract
The visualization of whole organs and organisms through tissue clearing and fluorescence volumetric imaging has revolutionized the way we look at biological samples. Its application to solid tumours is changing our perception of tumour architecture, revealing signalling networks and cell interactions critical in tumour progression, and provides a powerful new strategy for cancer diagnostics. This Review introduces the latest advances in tissue clearing and three-dimensional imaging, examines the challenges in clearing epithelia - the tissue of origin of most malignancies - and discusses the insights that tissue clearing has brought to cancer research, as well as the prospective applications to experimental and clinical oncology.

Abstract
OBJECTIVE To evaluate the role of axillary ultrasonography (axUS) and ultrasound-guided pre-operative wire localisation of pre-treatment positive clipped node (CN) for prediction of nodal response to neoadjuvant chemotherapy (NACT) in node positive breast carcinoma patients. METHODS AND MATERIALS A prospective study was conducted between June 2018 and August 2020 after Ethics Committee approval. Breast carcinoma patients (cT1-cT4b) with palpable axillary nodes (cN1-cN3) and suitable for NACT were recruited after written informed consent. Single, most suspicious node was biopsied and clipped. Nodal response to NACT was assessed on axUS. Wire localisation of CN was performed prior to axillary lymph node dissection (ALND). Diagnostic performances of axUS and CN excision were assessed. RESULTS Of the 69 patients evaluated, 32 patients (mean age, 43.5 ± 11.8 years; females, 31/32 [97%]; pre-menopausal, 18/32 [56.3%]) with metastatic nodes who received NACT were included. Nodal pathological complete response rate was 34.4% (11/32) overall and 70% (7/10) in patients with ≤2 suspicious nodes on pre-NACT axUS. False-negative rates (FNRs) of axUS and CN excision were 4.8% and 28.6% respectively. Combination of post-NACT axUS and CN excision had an FNR of 4.8% overall and 0% in patients with ≤2 suspicious nodes on pre-NACT axUS. CONCLUSION Combination of AxUS and ultrasound-guided wire localisation of pre-treatment positive CN has high diagnostic accuracy for nodal restaging after NACT in node positive breast cancer patients. ADVANCES IN KNOWLEDGE Addition of axUS assessment to wire localisation of CN reduces its FNR for detecting residual metastasis after NACT.

Abstract
Purpose Neoadjuvant chemotherapy (NACT) is increasingly adopted in the therapy of breast cancer (BC) patients with positive axillary nodes (cN+), but the reliability and feasibility of sentinel lymph node biopsy (SLNB) following NACT are still controversial. The objective of the present study is to conduct an updated meta-analysis on this issue. Methods A literature search was performed using PubMed, Cochrane, Embase, and Web of Science to identify papers published from January 1, 2000 to October 22, 2020 to research SLNB after NACT in BC patients. Studies that met the quality standard were enrolled for this meta-analysis. Results A total of 3578 participants from 27 trials were included in this meta-analysis. The pooled estimate of the identification rate (IR) for SLNB was 91 %, and the false negative rate (FNR) was 15 %. The pooled negative prediction value (NPV), accuracy, specificity, and sensitivity were 82 %, 89 %, 97 %, and 85 %, respectively. In subgroup analysis, the application of dual mapping could clearly decrease the FNR. The FNR was significantly high in the luminal types, and it declined as more sentinel lymph nodes (SLNs) were removed. Conclusion SLNB following NACT is now technically feasible for BC with cN+. However, it must be emphasized that the FNR is unacceptable high. We performed a meta-analysis to provide a consensus regarding the application of SLNB post-NACT in cN + patients. One comprehensive database search yielded 27 studies (3578 patients). The pooled estimate of IR for SLNB was 91 %, and FNR was 15 %. The application of dual mapping could clearly decrease the FNR.

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.

Accuracy of Intraoperative Frozen Section of Sentinel Lymph Nodes After Neoadjuvant Chemotherapy for Breast Carcinoma. Am J Surg Pathol 2020; 43:1377-1383.

Abstract
False-negative (FN) intraoperative frozen section (FS) results of sentinel lymph nodes (SLN) have been reported to be more common after neoadjuvant chemotherapy (NAC) in the primary surgical setting. We evaluated SLN FS assessment in breast cancer patients treated with NAC to determine the FN rate and the histomorphologic factors associated with FN results. Patients who had FS SLN assessment following NAC from July 2008 to July 2017 were identified. Of the 711 SLN FS cases, 522 were negative, 181 positive, and 8 deferred. The FN rate was 5.4% (28/522). There were no false-positive results. Of the 8 deferred cases, 5 were positive on permanent section and 3 were negative. There was a higher frequency of micrometastasis and isolated tumor cells in FN cases (P<0.001). There was a significant increase in tissue surface area present on permanent section slides compared with FS slides (P<0.001), highlighting the inherent technical limitations of FS and histologic under-sampling of tissue which leads to most FN results. The majority (25/28, 89%) of FN cases had metastatic foci identified exclusively on permanent sections and were not due to a true diagnostic interpretation error. FN cases were more frequently estrogen receptor positive (P<0.001), progesterone receptor positive (P=0.001), human epidermal growth factor receptor-2 negative (P=0.009) and histologic grade 1 (P=0.015), which most likely reflects the lower rates of pathologic complete response in these tumors. Despite its limitations, FS is a reliable modality to assess the presence of SLN metastases in NAC treated patients.

Abstract
Objective: The aim of this study was to perform a systematic review and meta-analysis to assess the accuracy of different surgical axillary staging procedures compared with ALND. Summary of Background Data: Optimal axillary staging after neoadjuvant systemic therapy (NST) in node-positive breast cancer is an area of controversy. Several less invasive procedures, such as sentinel lymph node biopsy (SLNB), marking axillary lymph node with radioactive iodine seed (MARI), and targeted axillary dissection (a combination of SLNB and a MARI-like procedure), have been proposed to replace the conventional axillary lymph node dissection (ALND) with its concomitant morbidity. Methods: PubMed and Embase were searched for studies comparing less invasive surgical axillary staging procedures to ALND to identify axillary burden after NST in patients with pathologically confirmed node-positive breast cancer (cN+). A meta-analysis was performed to compare identification rate (IFR), false-negative rate (FNR), and negative predictive value (NPV). Results: Of 1132 records, 20 unique studies with 2217 patients were included in quantitative analysis: 17 studies on SLNB, 1 study on MARI, and 2 studies on a combination procedure. Overall axillary pathologic complete response rate was 37%. For SLNB, pooled rates of IFR and FNR were 89% and 17%. NPV ranged from 57% to 86%. For MARI, IFR was 97%, FNR 7%, and NPV 83%. For the combination procedure, IFR was 100%, FNR ranged from 2% to 4%, and NPV from 92% to 97%. Conclusion: Axillary staging by a combination procedure consisting of SLNB with excision of a pre-NST marked positive lymph node appears to be most accurate for axillary staging after NST. More evidence from prospective multicenter trials is needed to confirm this.

Breast cancer metastasis through the lympho-vascular system. Clin Exp Metastasis 2018; 35:443-454.

Abstract
Breast cancer metastasizes through the lymphovascular system to the regional lymph nodes in the axilla and to both visceral and non-visceral sites. Renewed interest in the route by which tumor cells gain access to blood and lymphatic capillaries are the subject of research at mechanical, anatomic, pathologic, genetic, epidemiologic and molecular levels. Two papers presented at the 7th International Symposium on Cancer Metastasis in San Francisco showed tumor cells entering the systemic circulation through the sentinel lymph node. This information challenges the current paradigm where clinicians believe that access is gained through intra- and peri-tumoral blood vessels and that metastasis to axillary lymph nodes is an interesting epi-phenomenon. The sentinel lymph node era has changed the modern surgical approach to the axilla and the basis of this change is summarized in this paper. A new approach to the management of axillary metastases after systemic therapy relies on determining whether there is a complete pathologic response; if no tumor is found in the previously biopsied node, a complete axillary lymph node dissection may be avoided. African American women seem to inherit a trait from West African ancestors and tend to develop more lethal types of breast cancer. These tumors may have a molecular machinery that enhances their ability to metastasize to visceral sites and future research may unearth the mechanisms for this phenomenon.

Abstract
Background Neoadjuvant chemotherapy (NAC) is widely used to treat breast cancer. Sentinel lymph node biopsy has replaced axillary lymph node dissection in patients who convert to node-negative status after NAC. However, few studies have evaluated the diagnostic performance of ultrasonography and magnetic resonance imaging (MRI) in determining axillary lymph node status after NAC. Purpose To evaluate the diagnostic performance of breast ultrasonography and MRI in determining residual metastatic axillary lymph node status after NAC for breast cancer and to identify histopathological factors affecting radiological performance. Material and Methods This study included 157 patients who underwent initial and follow-up preoperative breast ultrasonography and MRI before NAC between January and December 2010. The sensitivity, specificity, negative and positive predictive values, and accuracy of ultrasonography, MRI, and their combinations were evaluated. Results The sensitivity of ultrasonography, MRI, and their combination in post-NAC axillary imaging was 60.00%, 57.33%, and 65.33%, respectively; the specificity was 60.47%, 72.09%, and 60.47%, respectively. The positive predictive value was highest with MRI (78.18%). On univariate analysis, positive estrogen receptor status was associated with misdiagnosis by ultrasonography ( P = 0.002), MRI ( P = 0.002), and their combination ( P = 0.001). When residual metastatic lymph nodes were present, lymph nodes with macrometastasis (>2.0 mm) were associated with correct ultrasonography-based diagnosis ( P = 0.0027). Conclusion Imaging assists in predicting axillary lymph node status in patients undergoing NAC; however, is imprudent to omit sentinel lymph node biopsy or axillary lymph node dissection for staging in women determined to be node-positive.

Abstract
Sentinel lymph node dissection (SLND) is a standard axillary staging technique in breast cancer and intraoperative sentinel lymph node (SLN) assessment is important for decision-making regarding additional treatment and reconstruction. This study was undertaken to investigate clinicopathologic factors impacting the accuracy of intraoperative SLN evaluation. Records of patients with clinically node-negative, invasive breast cancer who underwent SLND with frozen section intraoperative pathologic evaluation from 2004 to 2007 were reviewed. Intraoperative SLN assessment results were compared to final pathology. Patients with positive SLNs that were initially reported as negative during intraoperative assessment were considered false negative (FN) events. Primary tumor histology, grade, receptor status, size, lymphovascular invasion (LVI), multifocality, neoadjuvant chemotherapy or hormonal therapy, number of SLNs retrieved, and SLN metastasis size were evaluated. The study included 681 patients, of whom 262 (38%) received neoadjuvant therapy. There were 183 (27%) patients who had a positive SLN on final pathology, of whom 60 (33%) had FN events. On univariate analysis, lobular histology, favorable histology, absence of LVI and micrometastasis were associated with a higher FN rate. On multivariate analysis, favorable and lobular histology and micrometastasis were independent predictors of FN events whereas LVI and receipt of neoadjuvant therapy were not statistically significant predictors. The accuracy of intraoperative SLN evaluation for breast cancer is affected by primary tumor histology and size of the SLN metastasis. There was no significant association between neoadjuvant therapy and the FN rate by intraoperative assessment. This information may be helpful in counseling patients about their risk for a FN intraoperative SLN assessment and for planning for immediate breast reconstruction in patients undergoing mastectomy.

Abstract
PURPOSE Sentinel lymph node (SLN) biopsy has been shown to be both accurate and feasible for women who receive neoadjuvant chemotherapy (NAC). Intraoperative assessment of SLN by frozen sections can produce false negative results. The aim of this study was to compare two different techniques of intraoperative assessment of SLN in breast cancer patients treated with NAC: frozen section (FS) and molecular assay (OSNA). METHODS A multicenter cohort of 320 consecutive breast cancer patients treated with NAC between 2010 and 2014 was analyzed. FS was performed intraoperatively in 166 patients (H&E cohort) and OSNA in 154 patients (OSNA cohort). RESULTS A mean of 2.15 SLNs by FS and 1.22 SLNs by OSNA was assessed (p = 0.03). SLN metastasis was found in 44 patients (26.5%) by FS and in 48 (31.2%) by OSNA (p = 0.4). There was no statistical significance in rates of macrometastasis (75%), micrometastasis (20.5%) or ITCs (4.5%) when assessed by FS compared to OSNA (52.3%, 36.3% and 11.4%, respectively) (p = 0.06). There were 10 patients in the H&E cohort with positive-SLN in the definitive pathology assessment with negative intraoperative FS. When OSNA and definitive pathology were compared, there were no differences in rates of macrometastasis (61.1%), micrometastasis (33.3%) nor ITCs (5.6%) (p = 0.5). Fifty-four patients in the H&E cohort and 44 in the OSNA cohort had ALND after positive-SLNs. ALND was performed in a second surgery in 10 patients (18.5%) in the H&E cohort for intraoperative FS false negative results, 90% being micrometastasis. 42 out of 44 patients (95.5%) in the OSNA cohort had an ALND in the same surgery (p = 0.03). CONCLUSIONS OSNA assay detects SLNs metastases as accurately as conventional pathology in the NAC setting. Intraoperative definitive assessment of the SLN by OSNA reduces the need for a second surgery for ALND in 18.5% of breast cancer patients with a positive-SLN after NAC.

Abstract
Background To evaluate the accuracy of sentinel lymph node biopsy (SLNB) after neoadjuvant chemotherapy (NAC) in breast cancer patients with axillary lymph node (ALN) metastasis. Methods A total of 122 patients with operable breast cancer were enrolled in this single-center retrospective study. Eighty patients were clinically diagnosed with a positive axillary lymph node (ALN) via imaging or physical examination (including 66 patients with biopsy-proven metastasis). The other 42 cases had a clinically negative ALN. After four sessions of neoadjuvant chemotherapy, patients were assigned to an ALN-positive or -negative group. The identification rate (IR) and false negative rate (FNR) were determined in the ALN-negative group. Results ALN changed from positive to negative after NAC in 48 patients. Among them, 46 had at least one SLN resected (total IR = 95.8 %). Eight of the 46 SLN-negative patients had pathologically confirmed metastasis of at least one non-SLN (FNR = 36 %). Fifty-five of the 56 patients with a biopsy-proven negative ALN remained ALN negative. Furthermore, 54 of the 56 patients had at least one SLN resected (IR =98.2 %). Three SLN-negative patients of the 54 had at least one positive non-SLN (FNR = 10.7 %). Conclusions Due to its high FNR, post-NAC SLNB is not recommended for breast cancer patients with ALN metastasis confirmed by biopsy, though their ALN may become negative after NAC. However, for operable breast cancer with negative ALN, post-NAC SLNB is feasible if the ALN remains clinically negative after NAC. Trial registration Retrospective evaluation.

An updated meta-analysis involving 3,398 patients. Am J Surg 2016; 212:969-981.

Abstract
BACKGROUND The use of sentinel lymph node biopsy (SLNB) following neoadjuvant chemotherapy (NAC) in patients presenting with clinically positive lymph nodes remains controversial. METHODS A computer-aided search of the literature regarding SLNB in clinically node-positive breast cancer treated with NAC was carried out to identify the false negative rate (FNR), sentinel lymph node identification rate (IR), and axillary pathological complete response (pCR). RESULTS Nineteen articles were used in the analysis yielding 3,398 patients. The pooled estimate of the FNR was 13% and that of the IR was 91%. The adjusted pCR rate was 47%. A trend toward significance was observed with only clinical stage N1 (cN1) disease whereby clinical stage N1 was associated with an increased pCR rate when compared to N2 or N3 disease (P = .06). CONCLUSIONS SLNB after NAC in biopsy-proven node-positive patients results in reasonably acceptable FNR and IR, making it a valid alternative management strategy to axillary dissection. More refined patient selection and optimal techniques can improve the FNR and IR in this patient population.

Abstract
BACKGROUND False-negative rates (FNR) of sentinel node biopsy (SNB) after neoadjuvant chemotherapy (NAC) in node-positive (N+) breast cancer patients are <10 % when ≥3 negative SNs are obtained. Marking positive nodes has been suggested to reduce FNR. Identification of treatment effect in the nodes post-NAC is an alternative to decrease FNR. We evaluated the frequency of treatment effect in N+ patients after a pathologic complete response (pCR) with NAC. METHODS Biopsy-proven N+ patients receiving NAC were identified. Patients with nodal pCR after axillary lymph node dissection (ALND) or SNB with dual mapping and ≥3 SNs removed were evaluated for treatment effect; ALND and SNB patients were compared. RESULTS From January 2009 to December 2015, 528 N+ patients received NAC. Of these, 204 had a nodal pCR, 135 had an ALND, and 69 had SNB. Median age was 49 years, 15 % were hormone receptor positive (HR+)/HER2-, 27 % triple negative, and 58 % HER2+. The median number of nodes removed in ALND patients was 17 versus 4 in SNB patients. Treatment effect in nodes was identified in 192 patients (94 %) and was more common in ALND versus SNB patients (97 vs 88 %; p = .02). HR+ patients and patients without a breast pCR were less likely to have treatment effect in the nodes (p = .05). Other characteristics did not differ. CONCLUSIONS Following NAC, SNs with treatment effect were retrieved in 88 % of patients without marking nodes, suggesting that nodal clipping may not be necessary to achieve an acceptable FNR. Longer follow-up is needed to determine regional recurrence rates in the SN-only cohort.

Abstract
Purpose The purposes our study was to find out any histologic factors associated with negative conversion of axillary lymph node (ALN) after neoadjuvant chemotherapy (NAC). We also evaluated the association between the decrease in size of primary breast tumor and negative conversion of ALN. Methods From January 2012 to November 2014, we included 133 breast cancer patients who underwent NAC and who had ALN metastases which were confirmed on fine-needle aspiration or core needle biopsy at initial diagnosis. All 133 patients underwent initial magnetic resonance imaging (MRI) at the time of diagnosis and preoperative MRI after completion of NAC. We measured the longest dimension of primary breast cancer on MRI. Results Of 133 patients, 39 patients (29%) showed negative conversion of ALN and of these 39 patients, 25 patients (64%) showed pathologic complete remission of primary breast. On univariate analysis, mean percent decrease in longest dimension, estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2 status and histologic grade were significantly associated with the ALN status after NAC (p<0.001, p=0.001, p< 0.001, p=0.001, p=0.002, respectively). On multivariate logistic regression analysis, percent decrease in longest dimension (odds ratio, 1.026; 95% confidence interval [CI], 1.009-1.044) and histologic grade (odds ratio, 3.964; 95% CI, 1.151-13.657) were identified as being independently associated with the ALN status after NAC. The area under the receiver operating characteristic curve was 0.835 with the best cutoff value of 80% decrease in longest dimension. Combination of high histologic grade and more than 80% decrease in longest dimension showed 64% sensitivity and 92% specificity. Conclusion High histologic grade and more than 80% decrease in primary tumor dimension were associated with negative conversion of ALN after NAC.

Abstract
PURPOSE To provide a systematic review and meta-analysis of studies investigating sentinel lymph node biopsy after neoadjuvant systemic therapy in pathologically confirmed node positive breast cancer patients. METHODS Pubmed and Embase databases were searched until June 19th, 2015. All abstracts were read and data extraction was performed by two independent readers. A random-effects model was used to pool the proportion for identification rate, false-negative rate (FNR) and axillary pCR with 95% confidence intervals. Subgroup analyses affirmed potential confounders for identification rate and FNR. RESULTS A total of 997 abstracts were identified and eventually eight studies were included. Pooled estimates were 92.3% (90.8-93.7%) for identification rate, 15.1% (12.7-17.6%) for FNR and 36.8% (34.2-39.5%) for axillary pCR. After subgroup analysis, FNR is significantly worse if one sentinel node was removed compared to two or more sentinel nodes (23.9% versus 10.4%, p = 0.026) and if studies contained clinically nodal stage 1-3, compared to studies with clinically nodal stage 1-2 patients (21.4 versus 13.1%, p = 0.049). Other factors, including single tracer mapping and the definition of axillary pCR, were not significantly different. CONCLUSION Based on current evidence it seems not justified to omit further axillary treatment in every clinically node positive breast cancer patients with a negative sentinel lymph node biopsy after neoadjuvant systemic therapy.

Abstract
The use of sentinel node biopsy (SNB) after neoadjuvant chemotherapy (NAC) in patients with locally advanced breast cancer is debated. Our aim was to quantitatively review the available evidence on the performance of SNB after NAC in patients with locally advanced breast cancer. We performed a systematic review (by searching the PubMed, Cochrane and Scopus databases) and random effects meta-analysis to investigate on the feasibility and accuracy of SNB in these patients. The two outcomes of interest were the sentinel node identification rate (SIR) and the false negative rate (FNR). Sensitivity analysis and meta-regression were used to investigate the potential sources of between-study heterogeneity. We retrieved 72 eligible studies enrolling 7,451 patients. Upon meta-analysis, summary SIR resulted 89.6% [95% confidence interval (CI): 87.8-91.2; heterogeneity I(2): 76.9%], which poorly compares with the 95% SIR observed in some recent series of early breast cancer. The summary FNR resulted 14.2% (CI: 12.5-16.0; heterogeneity I(2): 29.1%), which was significantly higher than the 8-10% reference value. Considering an average post-NAC lymph node positivity rate of 50%, the downstaging due to false negative SNB would occur in 7/100 patients (with an excess error rate of 2-3/100 as compared to the early-stage setting). No plausible source of between-study heterogeneity was found. Based on the largest series of studies ever meta-analyzed, our findings highlight the limits of SNB performance in this population, where the impact of SNB on patient survival is still to be defined.

Feasibility and accuracy of sentinel lymph node biopsy in clinically node-positive breast cancer after neoadjuvant chemotherapy: a meta-analysis. PLoS One 2014; 9:e105316.

Abstract
Sentinel lymph node biopsy (SLNB) has replaced conventional axillary lymph node dissection (ALND) in axillary node-negative breast cancer patients. However, the use of SLNB remains controversial in patients after neoadjuvant chemotherapy (NAC). The aim of this review is to evaluate the feasibility and accuracy of SLNB after NAC in clinically node-positive patients. Systematic searches were performed in the PubMed, Embase, and Cochrane Library databases from 1993 to December 2013 for studies on node-positive breast cancer patients who underwent SLNB after NAC followed by ALND. Of 436 identified studies, 15 were included in this review, with a total of 2,471 patients. The pooled identification rate (IR) of SLNB was 89% [95% confidence interval (CI) 85-93%], and the false negative rate (FNR) of SLNB was 14% (95% CI 10-17%). The heterogeneity of FNR was analyzed by meta-regression, and the results revealed that immunohistochemistry (IHC) staining may represent an independent factor (P = 0.04). FNR was lower in the IHC combined with hematoxylin and eosin (H&E) staining subgroup than in the H&E staining alone subgroup, with values of 8.7% versus 16.0%, respectively (P = 0.001). Thus, SLNB was feasible after NAC in node-positive breast cancer patients. In addition, the IR of SLNB was respectable, although the FNR of SLNB was poor and requires further improvement. These findings indicate that IHC may improve the accuracy of SLNB.

Abstract
CONTEXT The use of a touch preparation for intraoperative sentinel lymph node diagnosis has become a preferred method of many pathologists because of its reported high sensitivity and rapid turnaround time. However, after neoadjuvant chemotherapy many lymph nodes have significant treatment-related changes that may affect the diagnostic accuracy of the intraoperative evaluation. OBJECTIVE To determine the accuracy of touch preparation for the intraoperative diagnosis of metastatic breast carcinoma in the neoadjuvant setting. DESIGN We reviewed retrospectively the results of intraoperative evaluations for 148 different sentinel lymph nodes from 63 patients who had undergone neoadjuvant chemotherapy for invasive breast cancer at our institution. The intraoperative touch preparation results were compared with the final pathology reports in conjunction with relevant clinical data. RESULTS Use of touch preparation for the evaluation of sentinel lymph nodes intraoperatively after neoadjuvant therapy was associated with a low sensitivity of 38.6% (95% confidence interval [CI], 24.4-54.5) but high specificity of 100% (95% CI, 96.5-100). There was no difference in sensitivity rates between cytopathologists and noncytopathologists in this cohort (P = .40). Patients with invasive lobular carcinoma and those who had a clinically positive axilla before the initiation of neoadjuvant therapy were the most likely to have a false-negative result at surgery. CONCLUSIONS Intraoperative touch preparations should not be used alone for the evaluation of sentinel lymph nodes in the setting of neoadjuvant therapy for breast cancer because of low overall sensitivity.

Abstract
INTRODUCTION A controversial aspect of breast cancer management is the use of sentinel lymph node biopsy (SLNB) in patients requiring neoadjuvant chemotherapy (NCT). This paper discusses the detection rate (DT) and false negatives (FN) of SLNB after NCT to investigate the influence of initial nodal disease and the protocols applied. METHODS Prospective observational multicenter study in women with breast cancer, treated with NCT and SLNB post-NCT with subsequent lymphadenectomy. DT and FN rates were calculated, both overall and depending on the initial nodal status or the use of diagnostic protocols pre-SLNB. RESULTS No differences in DT between initial node-negative cases and positive cases were found (89.8 vs. 84.4%, P=.437). Significant differences were found (94.1 vs. 56.5%, P=0,002) in the negative predictive value, which was lower when there was initial lymph node positivity, and a higher rate of FN, not significant (18.2 vs. 43.5%, P=.252) in the same cases. The axillary study before SLNB and after the NCT, significantly decreased the rate of FN in patients with initial involvement (55.6 vs 12.5, P=0,009). CONCLUSIONS NCT means less DT and a higher rate of FN in subsequent SLNB, especially if there is initial nodal involvement. The use of protocols in axillary evaluation after administering the NCT and before BSGC, decreases the FN rate in these patients.

Abstract
OBJECTIVE This study evaluates the diagnostic accuracy of axillary lymph node fine needle aspiration (FNA) cytology in breast cancer and correlates it with clinical parameters/outcomes. STUDY DESIGN A total of 91 females underwent FNA of axillary lymph nodes at our institution from January 2007 to February 2013. The cases were classified as 'positive', 'negative for malignancy' and 'nondiagnostic'. RESULTS Forty-six cases (50.5%) had a histologic follow-up (4.4 ± 3.1 months); of these, 22 (47.8%) were true positive, 7 (15.2%) were true negative, 2 (4.3%) were false negative, 5 (11%) were false positive and 10 (21.7%) were nondiagnostic. However, cytological review of all false positive and false negative cases confirmed the presence or absence of tumor, respectively. All false positive cases had undergone preoperative neoadjuvant chemotherapy, with no residual tumor present, and a treatment effect identified only histologically. Meanwhile, the 2 false negative cases involved micrometastasis (≤ 1.5 mm). Thus, if we exclude these false positive cases (complete responders), then the sensitivity, specificity, positive predictive value and negative predictive value were 91.7, 100, 100 and 77.8%, respectively. All preoperative FNA-positive axillary lymph nodes were spared from sentinel lymph node biopsy except for 3 of 27 (11.1%). CONCLUSION We suggest that axillary lymph node FNA is a highly sensitive technique with a low false negative rate (4.3%) and a diagnostic accuracy of 93.5%.

Abstract
Purpose Sentinel lymph node biopsy (SLNB) is an accurate and effective means of axillary nodal staging in early breast cancer. However its indication after neoadjuvant chemotherapy (NAC) is under constant debate. The present study evaluates the reliability of SLNB in assessing axillary nodal status after NAC. Methods Data from 281 patients who had received NAC and subsequent SLNB were reviewed. The identification and false negative rates of SLNB were determined and the clinicopathologic factors associated with false negative results were investigated using univariate analysis. Results The identification rate of SLNB after NAC was 93.6% and the false negative rate was 10.4%. Hormone receptor status, especially progesterone receptor positivity, was significantly associated with false negative results. The accuracy of intraoperative frozen section examination of sentinel lymph nodes was 91.2%. Conclusion The identification rate of SLNB and the accuracy of intraoperative frozen section examination after NAC are comparable to the results without NAC in patients with early breast cancer. However considering the high false negative rates, general application of SLNB after NAC should be avoided. Patients with progesterone-positive tumors and non-triple-negative breast cancers may be a select group of patients in whom SLNB can be employed safely after NAC, but further studies are necessary.

Intraoperative sentinel node biopsy by one-step nucleic acid amplification (OSNA) avoids axillary lymphadenectomy in women with breast cancer treated with neoadjuvant chemotherapy. Eur J Surg Oncol 2013; 39:873-9.

Abstract
BACKGROUND There is no evidence that supports the recommendation of sentinel lymph node biopsy (SLNB) in patients with breast cancer who have treated with neoadjuvant chemotherapy (NAC) to downsize tumors in order to allow breast conservation surgery, because NAC induces anatomical alterations of the lymphatic drainage. We evaluated the effectiveness of SLNB using intraoperative one-step nucleic acid amplification (OSNA) method to detect microscopic metastases or isolated tumor cells after NAC in patients with clinically negative axillary nodes at initial presentation. PATIENTS AND METHODS We evaluated in patients with breast cancer and clinically negative axilla at presentation, the effectiveness of SLNB by OSNA after NAC (71 patients) or prior to NAC (40 patients). RESULTS The rate of SLN identification was 100% in both groups. 17 women with SLNB prior to systemic treatment showed positive nodes (14 macrometastases and 3 micrometastases), and positive SLNB were detected in 15 women with SLNB after NAC, which were 14 macrometastases and 1 micrometastase. The negative predictive value of ultrasonography was 57.5% in patients with SLNB prior to neoadjuvant therapy and 78.9% in patients with chemotherapy followed by SLNB. CONCLUSIONS Intraoperative SLNB using OSNA in women with clinically negative axillary lymph nodes at initial presentation who received NAC could predict axillary status with high accuracy. Also it allows us to take decisions about the indication or not to perform an axillary dissection at the moment, thus avoiding delay in the administration of chemotherapy and benefiting the patients from a single surgical procedure.

Abstract
BACKGROUND The performance of sentinel lymph node biopsy (SLNB) after neoadjuvant chemotherapy (NCT) was investigated in patients with locally advanced breast cancer (LABC). METHODS After NCT of 178 patients with cytology-proven axillary/supraclavicular nodes metastasis at the time of diagnosis, SLNB using radioisotope was performed including completion node dissection between 2008 and 2011. The detection rate, sensitivity, false negative rate (FNR), negative predictive value (NPV) and accuracy of SLNB were analyzed. RESULTS SLNB was successfully performed in 169 (94.9%) patients. Tumor nonresponse and extensive residual nodal disease were found to be significantly associated with detection failure of sentinel nodes. Sensitivity, FNR, NPV, and accuracy of SLNB were 78.0, 22.0, 75.8, and 87.0%, respectively, and a greater number of retrieved SLNs increased all four of these performance measures. Conversion to node-negative disease was achieved in 69 (40.8%) patients: 24% of patients with the luminal A subtype, 51.6% of patients with the luminal B, 51.7% of patients with the HER2-enriched, and 58.5% of patients with the triple-negative breast cancer (TNBC) subtype. Luminal B, HER2-enriched, and TNBC subtypes showed comparable responses to NCT; however, the TNBC subtype had a significantly better FNR and accuracy. CONCLUSIONS SLNB was found to be technically feasible, but its routine use was not recommended for LABCs after NCT. However, acceptable performance was noted for locally advanced TNBCs, and thus SLNB might be safely considered in these selected patients.

Abstract
BACKGROUND Sentinel lymph node (SLN) dissection has been investigated after neoadjuvant chemotherapy and has shown mixed results. Our objective was to evaluate SLN dissection in node-positive patients and to determine whether postchemotherapy ultrasound could select patients for this technique. METHODS Between 1994 and 2010, 150 patients with biopsy proven axillary metastasis underwent SLN dissection after chemotherapy and 121 underwent axillary lymph node dissection (ALND). Clinicopathologic characteristics were analyzed before and after chemotherapy. Statistical analyses included Fisher's exact test for nodal response and multivariate logistic regression for factors associated with false-negative events. RESULTS Median age was 52 years. Median tumor size at presentation was 2 cm. The SLN was identified in 93 % (139/150). In 111 patients in whom a SLN was identified and ALND performed, 15 patients had a false-negative SLN (20.8 %). In the 52 patients with normalized nodes on ultrasound, the false-negative rate decreased to 16.1 %. Multivariate analysis revealed smaller initial tumor size and fewer SLNs removed (<2) were associated with a false-negative SLN. There were 63 (42 %) patients with a pathologic complete response (pCR) in the nodes. Of those with normalized nodes on ultrasound, 38 (51 %) of 75 had a pCR. Only 25 (33 %) of 75 with persistent suspicious/malignant-appearing nodes had a pCR (p = 0.047). CONCLUSIONS Approximately 42 % of patients have a pCR in the nodes after chemotherapy. Normalized morphology on ultrasound correlates with a higher pCR rate. SLN dissection in these patients is associated with a false-negative rate of 20.8 %. Removing fewer than two SLNs is associated with a higher false-negative rate.

Abstract
Neoadjuvant therapy (NAT) originally reserved for the treatment of inflammatory and locally advanced breast cancers is currently offered to women with earlier-stage and operable breast carcinoma. NAT allows more women to be eligible for breast conservation surgery and provides an opportunity to assess the response of carcinomas to therapy. This review focuses on the predictors of therapeutic response in pretreatment tumor, evaluation of post-treatment breast and lymph node specimens and classification systems to evaluate degree of response to NAT.

Abstract
INTRODUCTION The timing of sentinel lymph node biopsy (SLNB) of breast cancer in the neoadjuvant setting is still controversial. We retrospectively analyzed a Chinese patient cohort with neoadjuvant chemotherapy (NAC) to evaluate the accuracy and axilla sparing potentials of different SLNB timings with methylene blue alone for lymphatic mapping. MATERIALS AND METHODS Patients with NAC and axillary lymph node dissection (ALND) and either pre- or post-NAC SLNB were eligible. Clinicopathological characteristics, identification rate (IR), false-negative rate (FNR), accuracy, and positive-predictive value were calculated and compared between the pre- and post-NAC SLNB group using appropriate statistical methods. Axilla sparing potentials of different SLNB timings were evaluated and compared. RESULTS One hundred and fifteen eligible cases were included, and 58 had pre-NAC SLNB while the other 57 had post-NAC SLNB. Both groups were comparable in clinicopathological characteristics, neoadjuvant treatments and pathologic complete response rate. IR, FNR, and accuracy of SLNB, as pre-NAC versus post-NAC, were 100 versus 98.2 % (P = 0.496), 0 versus 8.0 % (P = 0.181), and 100 versus 96.4 % (P = 0.239), respectively. Post-NAC SLNB had significantly higher positive-predictive value for ALNs than pre-NAC SLNB (70.0 vs. 36.4 %, P = 0.014), suggesting as high as 63.6 % of ALND performed in the pre-NAC group could have been avoided while only 30 % of ALND in the post-NAC group were theoretically unnecessary. CONCLUSIONS Both SLNB timings of breast cancer patients with NAC were feasible and accurate. Although pre-NAC SLNB tends to be better in accuracy, post-NAC SLNB is significantly superior in terms of axilla sparing.

Abstract
Accurate pathological diagnosis of tumor mass before treatment and careful examination of specimens after treatment are two main objectives in the diagnostic process of neoadjuvant-treated breast cancer. To achieve the first objective, multiple core biopsies can be taken to assess intratumor heterogeneity and thus to address a more targeted therapeutic protocol. At the same time, fine needle aspiration cytology of lymph nodes found suspicious at ultrasound examination may be useful to plan surgical treatment. As for the second objective, a careful examination of specimens after primary systemic therapy is mandatory to evaluate the effect of treatment. In fact, clinical response does not necessarily correlate with pathological response. Pathological complete response (no residual invasive tumor, in situ carcinoma can be present, and no residual lymph node metastasis) constitutes an independent predictor of outcome in neoadjuvant-treated patients. Residual isolated tumor cells in primary tumor and in lymph nodes do not affect patient outcome.

Abstract
PURPOSE OF REVIEW Breast cancer is the most common malignancy in women in the United States and the second most common cause of cancer death in women. This review will focus on the current and clinically relevant recommendations for breast cancer diagnosis, staging, and treatment. RECENT FINDINGS Screening for breast cancer is based on patient history, exam, mammography, and ultrasound. In select patient populations, MRI adds additional detection benefit. Once pathology is found, nipple-sparing mastectomy is felt to be an oncologically well tolerated procedure for both ductal carcinoma in situ and invasive tumors in properly selected patients. Prophylactic mastectomy rates are increasing despite no clear survival benefit. Sentinel lymph node biopsy continues to be the staging procedure of choice, but data are available that completion axillary dissection for a positive sentinel node may not affect outcomes. SUMMARY Strategies for caring for breast cancer patients continue to evolve. Multiple variables including genetic predisposition, disease burden, tumor markers, receptor status, and patient preference are integral to the decision making for each individual patient.

Abstract
BACKGROUND The number of examined axillary lymph nodes (ALN) has been proposed as an indicator of prognosis along with quality and adequacy in breast cancer surgery. The purpose of this study was to examine the utility of imaging axillary specimens with x-ray (lymphogram) to determine the number of lymph nodes. We sought to determine the sensitivity and specificity of a lymphogram in identifying nodal positivity. METHODS Patients who underwent sentinel lymph node (SLN) and axillary lymph node dissections (ALND) were prospectively accrued to this double-blinded, single-institution trial from December 2009 to January 2011. A single physician interpreted all lymphograms for the number of ALNs and positivity determined by size, spiculations, irregularities, and calcifications. RESULTS Twenty female (age 50.8 ± 14.3 years) patients were accrued to the study. The lymphogram located more lymph nodes compared with pathology in 11 of 16 cases (68.8%). In these 11 cases, lymphogram identified 170 nodes and the pathologist located 132 (77.6%). Of the 16 ALND specimens, 6 were from patients naive to chemotherapy and averaged 13.8 ± 6.6 nodes; 10 were from neoadjuvant chemotherapy patients and had an average number of 14.9 ± 7.4 nodes. In neoadjuvant chemotherapy patients, sensitivity of the lymphogram to detect nodal positivity was 91.7% and specificity was 33.3%. CONCLUSIONS This study demonstrated that lymphogram accurately identifies nodal count. This can be used for documentation of an adequate ALND for reimbursement. Furthermore, there may be potential value of lymphogram in intraoperative determination of nodal positivity.
