Abstract: PURPOSE: To present guidance for patients and physicians regarding the use of accelerated partial-breast irradiation (APBI), based on current published evidence complemented by expert opinion. METHODS AND MATERIALS: A systematic search of the National Library of Medicine's PubMed database yielded 645 candidate original research articles potentially applicable to APBI. Of these, 4 randomized trials and 38 prospective single-arm studies were identified. A Task Force composed of all authors synthesized the published evidence and, through a series of meetings, reached consensus regarding the recommendations contained herein. RESULTS: The Task Force proposed three patient groups: (1) a "suitable" group, for whom APBI outside of a clinical trial is acceptable, (2) a "cautionary" group, for whom caution and concern should be applied when considering APBI outside of a clinical trial, and (3) an "unsuitable" group, for whom APBI outside of a clinical trial is not generally considered warranted. Patients who choose treatment with APBI should be informed that whole-breast irradiation (WBI) is an established treatment with a much longer track record that has documented long-term effectiveness and safety. CONCLUSION: Accelerated partial-breast irradiation is a new technology that may ultimately demonstrate long-term effectiveness and safety comparable to that of WBI for selected patients with early breast cancer. This consensus statement is intended to provide guidance regarding the use of APBI outside of a clinical trial and to serve as a framework to promote additional clinical investigations into the optimal role of APBI in the treatment of breast cancer.

Abstract: The supplanting of radical mastectomy by simple mastectomy and then by lumpectomy plus radiation, the use of adjuvant therapy to alter the natural course of breast and colorectal cancer, the use of tamoxifen for the prevention of breast cancer, and the dramatic improvement in survival demonstrated with the use of the monoclonal antibody trastuzumab in women with HER2-positive breast cancer are all the direct results of research that has been carried out over the past 50 years by the National Surgical Adjuvant Breast and Bowel Project (NSABP). This National Cancer Institute-supported clinical cooperative trials group based in Pittsburgh, PA, currently has 200 member institutions and 700 satellite centers located throughout the United States, Canada, Puerto Rico, and Ireland. The NSABP's mandate is to conduct large randomized phase III trials to evaluate therapies designed to improve the treatment and prevention of breast and colorectal cancer. Over the past half century, the NSABP has entered more than 150,000 patients and participants into clinical studies that have changed the treatment of colorectal cancer and have revolutionized the treatment and prevention of breast cancer.

Abstract: Neo-adjuvant endocrine therapy has opened new alternatives for locally advanced breast cancer. Such therapy, which has permitted us to expand the treatment role of neo-adjuvant therapies, may be of great benefit to patient groups such as the elderly, those not suited for chemotherapy, and those whose response may not be optimal. This therapy also may be able to help us identify agents that could improve outcomes in the adjuvant setting as well as possible biologic predictors for outcome. The latest generation of endocrine therapy for breast cancer, aromatase inhibitors, has proved superior to tamoxifen in terms of toxicity and efficacy in the adjuvant setting and is currently being studied in other clinical trials. Current findings indicate that these agents are less toxic and better tolerated than neo-adjuvant chemotherapy and that third-generation anti-hormonal therapy offers improved tumor response compared with tamoxifen, which has resulted in increased breast conserving surgery. Biomarker findings of improved response in tumors that are both estrogen receptor positive and HER-2 positive as well as progesterone receptor positivity only will be important for planning future selective treatment and clinical trials.

Abstract: PURPOSE: This report describes interventions undertaken by the National Surgical Adjuvant Breast and Bowel Project (NSABP) to improve compliance with patient-reported outcome (PRO) assessments in the setting of multicenter cancer clinical trials. We describe the effectiveness of several interventions and of observational factors. METHODS: PRO submission rates were analyzed for the following three NSABP protocols: the Study of Raloxifene and Tamoxifen (STAR), B-32, and B-35. Institutions participating in protocol B-35 were randomly assigned to receive automated reminders of upcoming assessments or not. Compliance was analyzed with a logistic repeated measures mixed modeling. RESULTS: Compliance was high in the three protocols, with rates greater than 80% for nearly all time points. Institutions were a significant source of variability (P < .01). The largest institutions had the highest compliance in STAR (odds ratio [OR] = 0.68 for < 50 participants enrolled and OR = 0.82 for 50 to 99 participants enrolled v larger institutions; P < .001). Midsized institutions had highest compliance in B-32 (OR = 4.63 for 31 to 50 patients enrolled and OR = 3.12 for > 50 patients enrolled v small institutions; P = .007). Compliance increased with participant age in STAR (OR = 0.57, 0.89, and 1.01 for ages < 50, 50 to 60, and 60 to 70 years, respectively, v > 70 years; P < .001). Race was significant in B-32 (OR = 2.63 for white v nonwhite; P < .001) and in STAR (OR = 1.41 for white v nonwhite; P < .001). Treatment group was significant in B-32 (OR = 0.74; P = .006). The B-35 prospective reminder did not improve compliance significantly (P = .30), but in B-32, delinquency sanctions were significant (OR = 1.56; P = .007). CONCLUSION: Compliance in NSABP PRO studies is higher now than a decade ago. Results for compliance initiatives were mixed. Age and race are important factors, but institutional variation remains significant and largely unexplained.

Abstract: The incidence of ductal carcinoma in situ (DCIS) has markedly increased as a result of the use of screening mammography. Whether DCIS is a premalignant lesion or a cancer remains a cause of debate, but evidence supports the idea that DCIS evolves into invasive breast cancer based on histologic patterns, similar risk factors, and genetic similarities. Microcalcifications identified during mammography generally raise the suspicion of DCIS, and biopsy, often by core needle, confirms such a diagnosis. The extent of disease can be further delineated by breast magnetic resonance imaging. Radiation therapy in breast-conserving treatment, along with tamoxifen, decreases the overall rate of local recurrence in patients with DCIS. Studies in the treatment of DCIS exploring partial breast radiation and trastuzumab are under way. Ongoing investigations with comparative genomic hybridization suggest that there are independent, evolutionary genetic pathways within DCIS. Genome-wide microarray-based gene expression analyses are now providing new opportunities to discover genes that are specifically activated or inactivated during the course of breast cancer progression.

Abstract: OBJECTIVE: To critically review the theoretical and actual risks and benefits of accelerated partial breast irradiation (APBI) after breast-conserving surgery. SUMMARY BACKGROUND DATA: Because of rapid evolution of radiation therapy techniques related to brachytherapy and three-dimensional conformal radiation therapy, APBI has very recently come to the forefront as a potential local treatment option for women with breast cancer. This review aims to give an overview of the biologic rationale for APBI techniques, and benefits and limitations of APBI techniques. METHODS: The authors reviewed the currently available published world medical literature on breast-conserving surgery with and without postoperative irradiation; all studies involving partial breast irradiation, including brachytherapy, for breast cancer; and currently accruing and planned APBI trials. The focus of this review was the early results of treatment in terms of toxicity, complications, cosmesis, and local control. RESULTS: On average, approximately 3% of patients treated with breast-conserving surgery will have an in-breast local recurrence away from the original lumpectomy site with or without postoperative standard whole-breast irradiation. The results of phase I-II studies involving approximately 500 patients treated with APBI after breast-conserving surgery have been published. Although many of the studies have limited long-term follow-up and potential selection bias, early results suggest that toxicity, cosmesis, and local control are comparable to outcomes seen after breast-conserving surgery followed by standard whole-breast irradiation. CONCLUSIONS: Recent advances in radiation delivery and published series of partial breast irradiation support large randomized trials comparing APBI with standard whole-breast irradiation after breast-conserving surgery.

Abstract: The diagnosis and treatment of breast cancer has evolved significantly over the last 20 years. Breast-conserving therapy is replacing the Halstedian concept of "en bloc" resection. Difficulties in detection, pre- and postoperative planning and follow up continue to challenge the clinician. Women at high risk present a significant clinical dilemma. MRI technology in many of these areas is providing more information about detection, tumor size, extent, and response to treatment. The careful and thoughtful inclusion of MRI in clinical trials may help continue the advancement of breast cancer care. J. Magn. Reson. Imaging 2001;13:837-841.

Abstract: BACKGROUND: The goals of axillary-lymph-node dissection (ALND) are to maximise survival, provide regional control, and stage the patient. However, this technique has substantial side-effects. The purpose of the B-32 trial is to establish whether sentinel-lymph-node (SLN) resection can achieve the same therapeutic goals as conventional ALND but with decreased side-effects. The aim of this paper is to report the technical success and accuracy of SLN resection plus ALND versus SLN resection alone. METHODS: 5611 women with invasive breast cancer were randomly assigned to receive either SLN resection followed by immediate conventional ALND (n=2807; group 1) or SLN resection without ALND if SLNs were negative on intraoperative cytology and histological examination (n=2804; group 2) in the B-32 trial. Patients in group 2 underwent ALND if no SLNs were identified or if one or more SLNs were positive on intraoperative cytology or subsequent histological examination. Primary endpoints, including survival, regional control, and morbidity, will be reported later. Secondary endpoints are accuracy and technical success and are reported here. This trial is registered with the Clinical Trial registry, number NCT00003830. FINDINGS: Data for technical success were available for 5536 of 5611 patients; 75 declined protocol treatment, had no SLNs removed, or had no SLN resection done. SLNs were successfully removed in 97.2% of patients (5379 of 5536) in both groups combined. Identification of a preincision hot spot was associated with greater SLN removal (98.9% [5072 of 5128]). Only 1.4% (189 of 13171) of SLN specimens were outside of axillary levels I and II. 65.1% (8571 of 13 171) of SLN specimens were both radioactive and blue; a small percentage was identified by palpation only (3.9% [515 of 13 171]). The overall accuracy of SLN resection in patients in group 1 was 97.1% (2544 of 2619; 95% CI 96.4-97.7), with a false-negative rate of 9.8% (75 of 766; 95% CI 7.8-12.2). Differences in tumour location, type of biopsy, and number of SLNs removed significantly affected the false-negative rate. Allergic reactions related to blue dye occurred in 0.7% (37 of 5588) of patients with data on toxic effects. INTERPRETATION: The findings reported here indicate excellent balance in clinical patient characteristics between the two randomised groups and that the success of SLN resection was high. These findings are important because the B-32 trial is the only trial of sufficient size to provide definitive information related to the primary outcome measures of survival and regional control. Removal of more than one SLN and avoidance of excisional biopsy are important variables in reducing the false-negative rate.

Abstract: BACKGROUND: Even after careful clinical and mammographic evaluation, cancer is found in the contralateral breast in up to 10% of women who have received treatment for unilateral breast cancer. We conducted a study to determine whether magnetic resonance imaging (MRI) could improve on clinical breast examination and mammography in detecting contralateral breast cancer soon after the initial diagnosis of unilateral breast cancer. METHODS: A total of 969 women with a recent diagnosis of unilateral breast cancer and no abnormalities on mammographic and clinical examination of the contralateral breast underwent breast MRI. The diagnosis of MRI-detected cancer was confirmed by means of biopsy within 12 months after study entry. The absence of breast cancer was determined by means of biopsy, the absence of positive findings on repeat imaging and clinical examination, or both at 1 year of follow-up. RESULTS: MRI detected clinically and mammographically occult breast cancer in the contralateral breast in 30 of 969 women who were enrolled in the study (3.1%). The sensitivity of MRI in the contralateral breast was 91%, and the specificity was 88%. The negative predictive value of MRI was 99%. A biopsy was performed on the basis of a positive MRI finding in 121 of the 969 women (12.5%), 30 of whom had specimens that were positive for cancer (24.8%); 18 of the 30 specimens were positive for invasive cancer. The mean diameter of the invasive tumors detected was 10.9 mm. The additional number of cancers detected was not influenced by breast density, menopausal status, or the histologic features of the primary tumor. CONCLUSIONS: MRI can detect cancer in the contralateral breast that is missed by mammography and clinical examination at the time of the initial breast-cancer diagnosis.

Abstract: OBJECTIVE: To estimate the added cancer yield of magnetic resonance imaging (MRI) over mammography in the contralateral breast of patients with a recent diagnosis of breast cancer. METHODS: We conducted a prospective, international study of mammography and MRI in women with a recent diagnosis of unilateral breast cancer. Each subject received a mammogram, clinical breast exam (CBE), and MRI of the unaffected breast within a 90 day time period. Definitive diagnosis of suspicious findings was determined through biopsy and central pathology review. RESULTS: Of the 103 eligible women included in study analyses, MRI detected 4 cancers in the contralateral breast while mammography detected none. MRI resulted in 12% (95% CI, 6%-20%) of women recommended for biopsy and 10% of women undergoing additional biopsy. The added cancer yield of MRI was 4% (95% CI, 1%-10%) and the positive predictive value of an abnormal MRI was 33% (95% CI, 10%-65%). Forty percent (4/10) of the biopsies performed based on the MRI recommendation were positive for malignancy. CONCLUSION: In women with a recent breast cancer diagnosis, approximately 4% will have an otherwise occult invasive breast cancer detected in the opposite breast by MRI alone.

Abstract: OBJECTIVE: To train surgeons in a standardized technique of sentinel lymph node biopsy and to prepare them for the requirements of a prospective randomized surgical trial. SUMMARY BACKGROUND DATA: The NSABP B32 trial opened to accrual in May 1999. A significant component of this trial was a prerandomization training phase of surgeons performed by a group of core surgical trainers. The goals of this training phase were to expeditiously instruct surgeons in a standardized technique of sentinel lymph node biopsy and to educate those same surgeons in complete and accurate data collection and source documentation for the trial. METHODS: This study is a description of the training data collected in a prospective fashion for the training component for surgeon entry into the B32 trial, evaluating the effectiveness of the training program in regards to surgical outcomes and protocol compliance. RESULTS: Two hundred twenty-six registered surgeons underwent site visit training by a core surgical trainer and 187 completed training and were approved to randomize patients on the trial. The results of 815 training (nontrial) cases demonstrated a technical success rate for identifying sentinel nodes at 96.2% with a false negative rate of 6.7%. A protocol compliance analysis, which included the evaluation of 94 separate fields, showed mean protocol compliance of 98.6% for procedural fields, 95.5% for source documentation fields and 95.0% for data entry fields. CONCLUSIONS: This training and quality control program has resulted in a large number of surgeons capable of performing sentinel lymph node biopsy in a standardized fashion with a high degree of protocol compliance and pathologic accuracy. This will ensure optimal results for procedures performed on the randomized phase of the trial.

Abstract: PURPOSE: An accurate, intraoperative sentinel lymph node (SLN) test could decrease delayed axillary dissections. Molecular tests may be more sensitive than current intraoperative tests but historically have not been rapid enough and have not been properly validated. We present the results from a large, prospective evaluation of the first rapid molecular SLN test, the Breast Lymph Node (BLN) Assay. METHODS: A beta trial (n = 304) to determine the threshold levels of mammaglobin and cytokeratin 19 correlating with metastasis greater than 0.2 mm and a validation trial (n = 416) to validate the threshold cutoffs were conducted. Alternating portions from each SLN were processed for histology and the BLN Assay. RESULTS: BLN Assay performance against extensive permanent-section histology verified by central pathology review was similar to that expected of standard permanent-section histology: sensitivity, 87.6%; specificity, 94.2%; positive predictive value, 86.2%; and negative predictive value (NPV), 94.9%. In 319 patients with both frozen-section hematoxylin and eosin results and BLN Assay results, the BLN Assay had higher sensitivity (95.6%) and NPV (98.2%) than frozen section (sensitivity, 85.6%; NPV, 94.5%). The assay can be performed in approximately 36 to 46 minutes for one to three nodes. CONCLUSION: The BLN Assay allows a rapid evaluation of 50% of each SLN. Comparison with permanent-section histology on adjacent node pieces evaluated by expert pathologists indicated that the BLN Assay was more sensitive than current intraoperative techniques while maintaining high specificity. These data indicate that the assay may be clinically useful for intraoperative or postoperative axillary lymph node dissection decisions.

Abstract: BACKGROUND: Results vary regarding the utility of perioperative axillary ultrasound (AUS) and biopsy for detecting axillary metastases. METHODS: Patients diagnosed with invasive breast cancer from 2004 through 2005 who underwent preoperative AUS with or without biopsy, and their surgical pathologic findings were reviewed. RESULTS: Of 152 patients who underwent preoperative AUS, 38% had abnormal AUS findings. Sixty-two percent of biopsy specimens were positive. The sensitivity of AUS both with and without biopsy was 54%, and specificity was 96%. The positive predictive value was 91%, and the negative predictive value was 71%. CONCLUSIONS: Our results correlate favorably with published reports of preoperative AUS. Standardization of AUS report descriptors is needed. Preoperative AUS should be included in the preoperative workup of clinically node-negative patients. A positive biopsy specimen decreases the need for a sentinel lymph node biopsy specimen; however, a negative AUS result or biopsy specimen does not replace the need to obtain a sentinel lymph node biopsy specimen.

Abstract: BACKGROUND: Occult metastases, by definition, are not detected on initial examination. They may be present on slides but missed during screening or may be present in paraffin embedded tissue blocks and undetected without additional levels. Anticytokeratin immunohistochemistry (CK IHC) enhances detection of occult metastases, particularly micrometastases (> 0.2 mm but not larger than 2.0 mm) or isolated tumor cell clusters (< or = 0.2 mm). This study defines the rate at which pathologists miss metastases on CK IHC of sentinel lymph nodes (SLN). METHODS: CK IHC sections 0.5 and 1.0 mm from the original surface of SLN tissue blocks were screened by pathologists using standard bright field light microscopes (LM) and by supervised computer assisted cell detection (CACD). All blocks were from breast cancer patients, initially classified 'node negative' on review of routinely stained sections from the surface of each block. Cases missed by LM screening but detected by CACD defined false negative screens. RESULTS: Of 236 cases screened, LM detected 34 (14.4%; 95% CI: 9.6-20.2) cases and, in the 202 cases negative by LM, CACD detected an additional 30 (14.9%; 95% CI: 9.6-21.2%) cases with occult metastases. Occult metastases missed by LM screening ranged from 0.01 to 0.1 mm in greatest dimension. The probability of missing an occult metastasis < or = 0.02 mm; < or = 0.05 mm, and < or = 0.10 mm was 75%, 69.2%, and 61.2%, respectively. No occult metastases larger than 0.10 mm were missed by LM screening. CONCLUSIONS: Pathologists screening the CK IHC stained slides may frequently miss detecting metastases < 0.10 mm.

Abstract: Neoadjuvant therapy followed by breast-conserving surgery has become an acceptable option for patients with locally advanced breast cancer. Although a distinct survival benefit has not been demonstrated using this approach, several questions have been raised following such therapy including its effects on receptor status and tumor markers. The current study retrospectively reviews estrogen receptor (ER), progesterone receptor (PR), and HER2-neu status in 55 consecutive patients treated by neoadjuvant chemotherapy. Preoperative and postoperative tumor markers were available for 43 of the 55 patients (78%). The pathologic complete tumor response rate (pCR) for this group was 19 per cent (8/43). Of those patients who did not achieve a pCR (n = 35), a change in tumor markers was seen in 25.7 per cent (9/35) of patients. When compared to a control group not undergoing neoadjuvant therapy, a significantly higher percent change in marker expression was noted in the neoadjuvant group (25.7% vs 5.9%, P = 0.046). ER, PR, and HER2-neu status remain important prognostic indicators for breast cancer. Tumor markers are useful in planning adjuvant therapy regimens. In this review, nearly 19 per cent of patients achieved a pCR. In patients not achieving a pCR, one in four patients had at least one change in tumor marker status. This study demonstrates the importance of establishing receptor and marker status prior to neoadjuvant therapy, as many patients will achieve a pCR and make tumor analysis impossible. Postoperative marker studies should be performed given the possibility of a change in status. The clinical relevance of this data will require further long-term follow-up. Until such data becomes available, caution should be considered when basing adjuvant therapy regimens on preoperative tumor marker studies alone.

Abstract: Women with ductal carcinoma in situ (DCIS) are at substantially increased risk for a second breast cancer, but few strong predictors for these subsequent tumors have been identified. We used Cox regression modeling to examine the association between mammographic density at diagnosis of DCIS of 504 women from the National Surgical Adjuvant Breast and Bowel Project B-17 trial and risk of subsequent breast cancer events. In this group of patients, mostly 50 years old or older, approximately 6.6% had breasts categorized as highly dense (i.e., > or =75% of the breast occupied by dense tissue). After adjusting for treatment with radiotherapy, age, and body mass index, women with highly dense breasts had 2.8 (95% confidence interval [CI] = 1.3 to 6.1) times the risk of subsequent breast cancer (DCIS or invasive), 3.2 (95% CI = 1.2 to 8.5) times the risk of invasive breast cancer, and 3.0 (95% CI = 1.2 to 7.5) times the risk of any ipsilateral breast cancer, compared with women with less than 25% of the breast occupied by dense tissue. Our results provide initial evidence that the risk of second breast cancers may be increased among DCIS patients with highly dense breasts.

Abstract: Lymph node status remains the most important prognostic indicator for breast cancer. Recent reports have established that the accuracy of assessing lymph node status is proportional to the number of nodes dissected. The accuracy of axillary staging following neoadjuvant chemotherapy has been cited as a technical concern due to limited node retrieval. The current study attempts to evaluate the ability to perform sentinel node biopsy (SNB) and formal axillary node dissection (AND) following neoadjuvant chemotherapy and to compare these results with non-neoadjuvant patients. One hundred sixteen consecutive patients undergoing SNB with simultaneous AND were retrospectively reviewed. Forty-two of these patients were treated with neoadjuvant chemotherapy prior to AND. Overall success rate in performing SNB in the neoadjuvant group was 95 per cent, and no false negatives have been noted to date. The overall SNB success rate in the non-neoadjuvant group was also 95 per cent with a false negative rate of 3 per cent. After AND in each group, a mean of 21 nodes were retrieved in the neoadjuvant group and 17.9 nodes in the non-neoadjuvant group (P = 0.018). In the neoadjuvant group, there were 19 node positive patients (42%) and 21 patients (28%) in the non-neoadjuvant group (P = 0.16). The mean number of positive nodes per patient was also similar between the two groups (2.9 in the neoadjuvant group vs 1.67 in the non-neoadjuvant group, P = 0.10). Following neoadjuvant therapy, accurate evaluation of the axilla is feasible. In this study, the mean number of nodes is significantly different in favor of the neoadjuvant group, but there is no significant difference in the number of node positive patients identified or in the mean number of positive nodes identified per patient. SNB is technically feasible with accuracy similar to that seen in patients with no history of neoadjuvant therapy. Neoadjuvant chemotherapy extends the use of breast-conserving therapy without sacrificing the ability to accurately stage the axilla either by use of standard axillary dissection or SNB.

Abstract: The NSABP-32 trial is a randomized, phase III clinical trial to compare sentinel node (SN) resection to conventional axillary dissection in clinically node-negative breast cancer patients. The primary aims of the trial are to determine if removal of only SNs provides survival and regional control equivalent to those of axillary dissection, while diminishing the magnitude of surgically related side effects. In order to ensure consistency of the outcomes for this trial, a standardized method of SN surgery has been utilized for all cases. A secondary aim of the B32 trial is to evaluate whether patients with "occult" metastases in the SNs have worse survival. Accrual is taking place at 73 institutions in North America, and 217 surgeons are enrolling patients.

Abstract: Few studies have attempted to critically identify patient- and tumor-related factors that limit sentinel node biopsy (SNB). These studies have been limited by sample size and surgeon variability. The present study attempts to enumerate these limitations in a unique group of patients. One hundred twenty-five SNBs performed by a single surgeon between May 1997 and June 2001 were reviewed. Overall SNB was successful in 96 per cent of patients with a 97 per cent correlation with the axillary node dissection. Sentinel node identification was not affected by age, tumor size, tumor location, prior segmental resection, or neoadjuvant therapy. No false negatives were noted in the neoadjuvant group. The use of blue dye alone significantly understaged patients when compared with isotope alone (P = 0.02). SNB is a highly accurate method to identify axillary metastases and its limitations are not affected by patient or tumor related factors. In the present study SNB detection by both isotope and blue dye has been shown to be superior to blue dye alone. This finding demonstrates that these limitations may be overcome with the standardization of the technique used.

Abstract: BACKGROUND: After neoadjuvant chemotherapy, while results of sentinel node biopsy (SNB) are encouraging, conditions that may affect sentinel node (SN) detection and false negative rates with respect to clinical and pathological tumor response after neoadjuvant therapy require investigation. METHODS: Thirty-four patients with clinical stage I, II and IIIA invasive breast cancer underwent neoadjuvant chemotherapy with doxorubicin/cyclophosphamide or doxorubicin/cyclophosphamide and docetaxel/segmental resection, SNB, and axillary node dissection (AND). RESULTS: SNs were found in 31 of 34 patients (91.2%). SNs were found in 20 of 21 patients (95.2%) with complete clinical tumor response, it was positive in 40% and no false negatives occurred. SNs were found in 11 of 13 patients (84.6%) with partial or no clinical tumor response; in four patients (33%) the SN was positive and no false negative nodes were found. Seven patients had complete pathological tumor response. SNs were found in six of these patients (85.7%). The SN was positive in 1 of 6 patients (16.7%) with no false negative. In 25 of 27 patients (92%) with partial or no pathological tumor response, the SN was identified. Eleven of these patients (44%) had positive nodes with no false negatives. CONCLUSIONS: SN identification rate and accuracy after neoadjuvant chemotherapy for breast carcinoma were extremely good however there is potential for inaccuracy after less than complete pathological tumor response. Further evaluation of SNB in larger clinical trial is warranted prior to accepting this approach as a standard care.
