Abstract Introduction Sentinel lymph node biopsy (SLNB) is the gold standard for determining axillary nodal status. There is growing interest in using preoperative axillary ultrasound (AUS) as a non-invasive means of assessing the axilla. However, AUS has limited sensitivity and is subject to operator dependency. This study aimed to quantify axillary nodal burden in preoperative AUS. Method This retrospective study used an institutional database of all primary invasive breast carcinomas from 2006–2019. Those with pathologically proven axillary metastatic disease were included. Patients were considered in two groups, low nodal burden/LNB(1-2LN) and high nodal burden/HNB(≥3LN) based on total positive lymph node count(SLNB+ALND). Preoperative AUS reports were assessed to determine those suspicious for axillary metastasis. Result Of the 347 patients (n=349 axillae), 77.9% had LNB and 22.1% had HNB. In patients with LNB, 228(83.8%) had a normal AUS versus 44(16.2%) suspicious AUS. In those with HNB 60(77.9%) had normal AUS findings versus 17(22.1%) suspicious findings. On multivariate analysis Nottingham Grade-3 was associated with suspicious AUS findings (p=0.02). However, receptor status, SLN macro-metastasis and extra-nodal extension were not associated with abnormal AUS. Conclusion As the surgical approach to the axilla becomes increasingly conservative, detection of axillary involvement by non-invasive means is an area of increasing research. In this cohort, AUS did not reliably identify patients with axillary metastasis. These results highlight the challenges in accurately assessing the axilla using preoperative AUS, which may result in axillary undertreatment if used as an alternative to surgical staging. Take-home message As the surgical approach to the axilla becomes increasingly conservative, detection of axillary involvement by non-invasive means is an area of increasing research. This study highlights the challenges in accurately assessing the axilla using preoperative AUS, which may result in axillary undertreatment if used as an alternative to surgical staging.

We report the case of a 43-year-old woman with primary left breast cancer presenting metastatic lymphadenopathy in the contralateral axilla. This patient represents a diagnostic and therapeutic challenge because primary breast cancer, occult contralateral breast cancer, and extra-mammary primary lesion can all be the source of the contralateral axillary metastasis. Left breast-conserving surgery, left sentinel lymph node biopsy, right breast mass excision, and right axillary lymph node dissection were performed. Immunohistochemical analysis revealed that the left breast cancer specimen was positive for estrogen receptor (ER) and progesterone receptor (PR), but negative for human epidermal growth factor receptor 2 (HER2). In contrast, the right axillary lymphadenopathy specimen was negative for ER and PR, but positive for HER2. Further investigation revealed no evidence of occult primary cancers or extra-mammary tumors. After surgical intervention, the patient was treated with adjuvant chemotherapy, adjuvant radiation therapy, and targeted therapy with trastuzumab. Two years after diagnosis, she is free of disease and presently being treated with tamoxifen.

Sentinel lymph node biopsy (SLNB) following neoadjuvant treatment (NACT) has been questioned by many studies that reported heterogeneous identification (IR) and false negative rates (FNR). As a result, some patients receive axillary lymph node dissection (ALND) regardless of response to NACT, leading to a potential overtreatment. To better assess reliability and clinical significance of SLNB status on ycN0 patients, we retrospectively analyzed oncological outcomes of 399 patients treated between January 2016 and December 2019 that were either cN0-ycN0 (219 patients) or cN1/2-ycN0 (180 patients). The Endpoints of our study were to assess, furthermore than IR: oncological outcomes as Overall Survival (OS); Distant Disease Free Survival (DDFS); and Regional Disease Free Survival (RDFS) according to SLNB status. SLN identification rate was 96.8% (98.2% in patients cN0-ycN0 and 95.2% in patients cN+-ycN0). A median number of three lymph nodes were identified and removed. Among cN0-ycN0 patients, 149 (68%) were confirmed ypN0(sn), whereas regarding cN1/2-ycN0 cases 86 (47.8%) confirmed an effective downstaging to ypN0. Three year OS, DDFS and RDFS were significantly related to SLNB positivity. Our data seemed to confirm SLNB feasibility following NACT in ycN0 patients, furthermore reinforcing its predictive role in a short observation timing.

Sentinel lymph node biopsy (SLNB) is used to detect axillary lymph node metastases in breast cancer. Preoperative radiocolloid injection with lymphoscintigraphy (PL) is performed before SLNB. Few comparisons between 1- and 2-day PL protocols exist. Opponents of a 2-day protocol have expressed concerns of radiotracer washout to nonsentinel nodes. Proponents cite lack of scheduling conflicts between PL and surgery. A total of 387 consecutive patients with clinically node-negative breast cancer underwent SLNB with PL. Lymphoscintigraphy images were obtained within 30 minutes of radio-colloid injection. Axillary lymph node dissection was performed if the sentinel lymph node (SLN) could not be identified. Data were collected regarding PL technique and results. In all, 212 patients were included in the 2-day PL group and 175 patients in the 1-day PL group. Lymphoscintigraphy identified an axillary sentinel node in 143/212 (67.5%) of patients in the 2-day group and 127/175 (72.5%) in the 1-day group ( P = 0.28). SLN was identified at surgery in 209/212 (98.6%) patients in the 2-day group and 174/175 (99.4%) in the 1-day group ( P = 0.41). An average of 3 SLN was found at surgery in the 2-day group compared with 3.15 in the 1-day group ( P = 0.43). SLN was positive for metastatic disease in 54/212 (25.5%) patients in the 2-day group compared with 40/175 (22.9%) in the 1-day group ( P = 0.55). A 2-day lymphoscintigraphy protocol allows reliable detection of the SLN, of positive SLN and equivalent SLN harvest compared with a 1-day protocol. The timing of radiocolloid injection before SLNB can be left at the discretion of the surgeon.

Objectives: The feasibility and accuracy of sentinel lymph node biopsy (SLNB) in the treatment of breast cancer is widely acknowledged today. The aim of our study was to compare the hospital-related costs of this strategy with those of conventional axillary lymph node dissection (ALND).Methods: A retrospective study was carried out to determine the total direct medical costs for each of the two medical strategies. Two patient samples (n=43 for ALND; n=48 for SLNB) were selected at random among breast cancer patients at the Centre Léon Bérard, a comprehensive cancer treatment center in Lyon, France. Costs related to ALND carried out after SLNB (either immediately or at a later date) were included in SLNB costs (n=18 of 48 patients).Results: Total direct medical costs were significantly different in the two groups (median 1,965.86€ versus 1,429.93€, p=0.0076, Mann-Whitney U-test). The total cost for SLNB decreased even further for patients who underwent SLNB alone (median, 1,301€). Despite the high cost of anatomic pathology examinations and nuclear medicine (both favorable to ALND), the difference in direct medical costs for the two strategies was primarily due to the length of hospitalization, which differs significantly depending on the technique used (9-day median for ALND versus 3 days for SLNB, p<0.0001).Conclusions: A lower morbidity rate is favorable to the generalization of SLNB, when the patient's clinical state allows for it. From an economic point of view, SLNB also seems to be preferred, particularly because our results confirm those found in two published studies concerning the cost of SLNB.

Background : Locally advanced breast carcinoma (LABC) includes a wide range of clinical scenarios- advanced primary tumors (T4), advanced nodal disease and inflammatory carcinomas(1). Traditionally, treatment of LABC included a combination of Chemotherapy, Radiation and Surgery(2). However, there has been a shift to Neoadjuvant Chemotherapy in recent times.(3) Histological status and the number of axillary lymph nodes with metastasis is one of the most important prognostic factors and most powerful predictor of recurrence and survival in patients of breast carcinoma and remains so, even after neo-adjuvant chemotherapy. (3) Information derived from the sentinel lymph node is considered valuable, with less discomfort to the patient when compared with axillary dissection.(4) However, its role in detecting nodal metastasis after neo-adjuvant chemotherapy in LABC is still debatable and definitive studies to evaluate its role are still evolving. (5) Materials and Methods: Patients of LABC were evaluated using ultrasonography (USG) of axilla. Neo-adjuvant chemotherapy (NACT) was administered and patients were reassessed by USG of axilla. Thirty patients with node negative axillary status were subjected to Sentinel lymph node mapping using isosulfan blue followed by Modified Radical Mastectomy and Axillary Lymph Node Dissection. Histopathological evaluation of stained and unstained lymph nodes done and the data, thus obtained, was statistically analysed.   Results: Sentinel lymph node biopsy performed using Isosulfan Blue dye alone, after neo-adjuvant chemotherapy predicts the status of axillary lymph nodes with low accuracy.   Conclusions: Further studies would be required to establish the role of sentinel lymph node biopsy in patients with LABC after NACT.

BackgroundSentinel lymph node (SLN) biopsy is feasible for breast cancer (BC) patients with clinically negative axillary lymph nodes; however, complications develop in some patients after surgery, although SLN metastasis is rarely found. Previous predictive models contained parameters that relied on postoperative data, thus limiting their application in the preoperative setting. Therefore, it is necessary to find a new model for preoperative risk prediction for SLN metastasis to help clinicians facilitate individualized clinical decisions.Materials and MethodsBC patients who underwent SLN biopsy in two different institutions were included in the training and validation cohorts. Demographic characteristics, preoperative tumor pathological features, and ultrasound findings were evaluated. Multivariate logistic regression was used to develop the nomogram. The discrimination, accuracy, and clinical usefulness of the nomogram were assessed using Harrell’s C-statistic and ROC analysis, the calibration curve, and the decision curve analysis, respectively.ResultsA total of 624 patients who met the inclusion criteria were enrolled, including 444 in the training cohort and 180 in the validation cohort. Young age, high BMI, high Ki67, large tumor size, indistinct tumor margins, calcifications, and an aspect ratio ≥1 were independent predictive factors for SLN metastasis of BC. Incorporating these parameters, the nomogram achieved a robust predictive performance with a C-index and accuracy of 0.92 and 0.85, and 0.82 and 0.80 in the training and validation cohorts, respectively. The calibration curves also fit well, and the decision curve analysis revealed that the nomogram was clinically useful.ConclusionsWe established a nomogram to preoperatively predict the risk of SLN metastasis in BC patients, providing a non-invasive approach in clinical practice and serving as a potential tool to identify BC patients who may omit unnecessary SLN biopsy.

Sentinel lymph node biopsy (SLNB) emerged in the 1990s as a new technique in the surgical management of the axilla for patients with early breast cancer, resulting in lower complication rates and better quality of life than axillary lymph node dissection (ALND). Today SLNB is firmly established in the armamentarium of clinicians treating breast cancer, but several questions remain. The goal of this paper is to review recent work addressing 4 questions that have been the subject of debate in the use of SLNB in the past few years: (a) What is the implication of finding micrometastases in the sentinel nodes? (b) Is ALND necessary in all patients who have a positive SLNB? (c) How accurate is SLNB after neoadjuvant therapy? (d) Can SLNB be used to stage the axilla in locally recurrent breast cancer following breast surgery with or without prior axillary surgery?
