e12060 Background: In breast cancer, axillary lymph node involvement directly impacts the patient survival and prognosis.Sentinel lymph node biopsy (SLNB) is a procedure of choice for axillary staging in early breast cancer. Currently, management options for axilla management are ALND & SLNB in node positive & in node negative respectively. In developing nation like India,where resource constraints, logistics issues and over burden health institutes create difficulty in managing patients, our study address this issue by implementing USG and USG-FNAC in early breast cancer patients in developing nation. Methods: All early breast cancer patients were screend by ultrasound axilla to categorise the nodes as suspicious or non suspicious. Suspicious nodes underwent USG & FNAC using vascualr pedicle based nodal mapping for node targeted on USG-FNAC, if node found to be positive, patient underwent ALND & negative node patients underwent SLNB.All non-suspicious nodes patient underwent SLNB. Final histopathology was taken as gold standard. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value, accuacy and false negative rate calculated for USG & USG-FNAC. Results: Total 100 patients included in which 58 were non-suspicious and 42 suspicious nodes on USG. Among suspicious group, 24 were positive on USG-FNAC & 18 were negative.In non suspicious SLNB done in all. False negative rate of USG & USG-FNAC was 38% and 17% respectively. Conclusions: Our study indicates the feasibility of USG & USG-FNAC in a high volume centre with good accuracy of around 70- 80%.Overall, 24 % of total patients can be taken up for ALND without performing SLNB.This study can guide us to utilize ultrasound and ultrasound-guided FNAC as a routine evaluation tool in the pre operative assessment of axillary lymph nodes in early breast cancer. Our study showed good and acceptable result (75%) in isolating and retrieving the targeted node by just following the Vascular pedicle based node mapping of axilla to locate the suspicious node without using any tagging or marking of node from where FNAC was performed. This finding can act as a good practicing tool in a busy high volume, logistics issue and and resource constraint hospitals.[Table: see text]

11023 Background: Sentinel lymph node biopsy (SLNB) is a potential alternative procedure to conventional axillary lymph node dissection (ALND) in clinically node-negative breast cancer patients. Neoadjuvant chemotherapy (NAC) is a standard of care for patients with locally advanced breast cancer and indications of NAC have been widespread to operable breast cancer patients to facilitate breast conserving surgery. However, the validity of SLNB in breast cancer patients who received NAC is still controversial. Methods: Forty-six patients with stage II or III breast cancer who were treated with NAC from January 2002 to May 2006 were included in the study. Consecutive 122 patients who had SLNB without NAC during the same period were used as a control group. All patients underwent SLNB followed by completion ALND. Sentinel lymph node (SLN) was detected using a combined method of injecting isosulfan blue dye and small-sized technetium- 99m-labeled tin colloid (particle size: 200–400 nm in diameter) peritumorally and subcutaneously. SLNs were evaluated by means of H&E and immunohistochemical staining. Results: SLNs were successfully identified in 42/46 patients (91.3%) treated with NAC and 112/113 patients (99.1%) without NAC (p=0.01). Metastases in the SLNs were found in 16/42 patients (38.1%) with NAC and 32/112 patients (28.6%) without NAC (p=0.2). There were 5 false negative cases (false negative rate: 23.8%) in the NAC group and 2 false negative cases (false negative rate: 5.9%) in the control group (p=0.05). Accuracy of SLNB in the NAC group was also significantly inferior to the control group (88.1% vs. 98.2%, p<0.01). The presence of clinically positive axillary lymph nodes before NAC was not correlated with false negative rate. Conclusions: These data suggest that NAC might be considered a contraindication to SLNB even in patients with clinically negative axillary lymph nodes before NAC. No significant financial relationships to disclose.

AIM: This study aimed to examine the application of neoadjuvant chemotherapy (NAC) effect on sentinel lymph node biopsy (SLNB) using single method methylene blue 1% in breast cancer patients at low-resource country. METHODS: This analytical observational study employed a retrospective case–control approach. The total sampling method was used by involving the entire population of Stage-I and -II breast cancer patients after performed core biopsy or open biopsy with clinically negative axillary lymph nodes that had performed SLNB and axillary lymph nodes dissection at several hospitals in Surakarta from January to May 2020. The descriptive data were presented in the frequency table. Sensitivity, specificity, positive predictive value, negative predictive value (NPV), and diagnostic values were reported with 95% confidence of interval (CI). RESULTS: From a total of 161 patients, 100 patients were given NAC. The identification rate of the non-NAC was 91.3% and the NAC group 80.6%. Non-NAC group obtained a false-negative rate of 24.4% with NPV of 94.4% (95% CI 85–100), while the false-negative rate of the NAC group was 10.8% with NPV of 74% (95% CI 65–80). CONCLUSIONS: NAC with single method methylene blue 1% injection in SLNB can reduce the identification and false-negative rates in breast cancer patients.

Abstract Background: Axillary lymph node dissection can be avoided in early stage breast cancer patients with negative sentinel lymph node biopsy. However, the possibility of avoiding axillary surgery in patients without axillary lymph node metastasis (ALNM) by preoperative imaging is still under exploration. Thus, the objectives of this study were to investigate the high-risk factors of false negative of ALNM diagnosed by preoperative ultrasound (US) and to find out who could be avoided axillary surgery in the US negative ALNM patients.Methods: This study retrospectively analyzed 3,361 patients with primary early breast cancer diagnosed in the Breast Center of the Fourth Hospital of Hebei Medical University from January 2010 to December 2012. All patients had undergone routine preoperative US and then axillary lymph node dissected. This study investigated the clinicopathological features of axillary lymph node (ALN) negative patients diagnosed by preoperative US and its correlation with prognosis. The follow-up data for disease-free survival (DFS) and overall survival (OS) were obtained from 2,357 patients. Results: The sensitivity, specificity and accuracy of axillary US in this cohort were 66.24%, 76.62% and 73.87%. The proportion of patients in the false negative group was higher than that in true negative in the group of age < 50 years old (P = 0.002), tumor size > 2cm (P = 0.008), estrogen receptor (ER) positive (P = 0.005), progesterone receptor (PR) high expression (P = 0.007), nuclear-associated antigen Ki-67 (Ki-67) >20% (P = 0.030), visible vascular tumor thrombus (P < 0.001) and histological grade>2 (P < 0.001). Prognostic analysis of false negative and true negative ultrasonographic diagnosis of ALN metastasis: when ALNM was not found by preoperative ultrasound, there was no significant difference in patients with ALNM≤3 compared with patients without lymph node metastasis in patients of age ≥ 50 years old, tumor size ≤ 2cm, Ki-67 ≤ 20%, or histological grade ≤ 2. Conclusion: The surgery of ALN may be avoided for the preoperative US diagnosed ALNs negative in early breast cancer patients who had advanced age, small tumor size, low expression of Ki-67 and low histological grade.

Abstract Background: Sentinel lymph node biopsy (SLNB) is the standard approach of the axillary region for early breast cancer patients with clinically negative nodes. The present study investigated patients with false-negative sentinel nodes of intraoperative frozen section (FNSNs) in real-world data.Methods: A case–control study with a 1:3 ratio was conducted. FNSN was diagnosed when sentinel nodes (SNs) are negative in frozen sections but positive for metastasis in formalin-fixed paraffin-embedded (FFPE) sections. The control was defined as having no metastasis of SNs in both frozen and FFPE sections.Results: A total of 20 FNSN cases and 60 matched controls were enrolled from 333 SLNB patients between April 1, 2005, and November 31, 2009. The demographics and intrinsic subtypes of breast cancer were similar between FNSN and controls. The FNSN patients had larger tumor sizes in preoperative mammography (P = 0.033) and more lymphatic tumor emboli in core biopsy (P < 0.001). Four FNSN patients had metastasis in the non-relevant SNs. Another 16 FNSN patients had benign lymphoid hyperplasia of SNs in frozen sections and metastasis in the same SNs from the FFPE sections. Micrometastasis was detected in seven of 16 patients, and metastases in non-relevant SNs were recognized in two patients. All FNSN patients received a second operation with axillary lymph node dissection (ALND). After a median follow-up of 143 months, no FNSN patients developed recurrence of breast cancer. The disease-free survival, disease-specific survival, and overall survival in FNSN were not inferior to the controls.Conclusions: The patients with a larger tumor size and more lymphatic tumor emboli have a higher incidence of FNSN. However, outcomes of FNSN patients after completing ALND were noninferior to those without metastasis in SNs. ALND provides a correct diagnosis of patients with metastasis in non-sentinel axillary lymph nodes.

Abstract Background Sentinel lymph node biopsy is the gold standard surgical technique for axillary staging in patients with clinically node-negative. However, it is still uncertain what is the optimal number of sentinel lymph nodes (SLNs) to be removed to reduce the false-negative rate. The aim of this study was to investigate whether patients with a single negative SLN have a worse prognosis than those with two or more negative SLNs. Methods A retrospective review was conducted on a large series of SLN-negative breast cancer patients. Survival outcomes and regional recurrence rate were evaluated according to the number of removed SLNs. Secondly, the contribution of different adjuvant therapies on disease-free survival was explored. Statistical analysis included the chi-square, Wilcoxon–Mann–Whitney test, and Kaplan–Meier survival analysis. Results A total of 1080 patients were included in the study. A first group consisted of 328 patients in whom a single SLN was retrieved, and a second group consisted of 752 patients in whom two or more SLNs were retrieved. There was no relevant difference in median DFS (64.9 vs 41.4) for SLN = 1 vs SLN > 1 groups (HR 0.76, CI 95% 0.39–1.46; p = 0.38). A statistically significant difference in mDFS was showed only for HT-treated patients who were SLN = 1 if compared to SLN > 1 (100.6 months versus 35.3 months). Conclusions There is likely a relationship between the number of resected SNL and mDFS. Our results, however, showed no relevant difference in median DFS for SLN = 1 vs SLN > 1 group, except for a subset of the patients treated with hormone therapy.

2560 Background: It has been observed, that the caudal Axilla on the border to pectoralis muscle is predicive for the sentinel node. The sono-morphology of lymph nodes has been the subject of multiple publications, usually dealing with malignant melanoma. In the context of sentinel lymph node biopsy (SLNB) in breast cancer patients, the following study examines the feasibility of the sonographic differentiation of the Sentinel lymph node (SLN) from neighboring non-SLNs and whether sentinel-ultrasound-needle localization (SUN) is a useful addition or alternative to current methods of “lymphatic mapping”. Methods: During a prospective study performed from 1/2003 to 9/2005 including 404 breast cancer patients (Tis-T4), the SLNB was performed using patent blue+/- 99Tc-Nanocoll. In addition to and independent of this method, the axilla was sonographically examined for “reactive” lymph nodes n=180 pt. (Siemens Elegra 7.5 MHz). The “reactivity” of the nodes was quantified using an index , which allowed the comparison of adjacent nodes. The most “reactive” lymph node in the caudal axilla was identified as the “Ultrasound-Sentinel-Node”(US-SLN) and has been marked with a wire. Results: In 180 patients the SLN was localized using the standard methods as well as (SUN). The was no difference in detection rates of US-SLN and the standard methods in tumor-free nodes(SLN-). However, for patients with axillary metastases (SLN+) SUN provided superior detection rate (99,1%). The false-negative-rate was reduced from 10,7 % to 1,3%. This was attributed to the embolization of lymph vessels afferent to the metastasized (SLN+) node causing a bypass of the “lymphatic mapping” and inhibiting detection. Conclusions: The SUN–Method is comparable to “lymphatic mapping” in tumor free nodes (SLN -). If SLN is metastasized (SLN+) - SUN is superior to the standard methods in sensitivity and specificity (80%) and the false-negative-rate can be reduced. Systematic axilla sonography is an effective method for the SLN-Localisation, and offers an excellent method for quality control during SLNB.
