Abstract To verify whether omitting radiotherapy from breast cancer treatment for patients ≥ 70 years old following breast-conserving surgery (BCS) without axillary lymph node dissection is safe. Previous studies have shown that omitting breast radiotherapy after BCS and axillary lymph node dissection is safe for elderly breast cancer patients. We aimed to evaluate the safety of BCS without axillary surgery or breast radiotherapy (BCSNR) in elderly patients with breast cancer and clinically negative axillary lymph nodes. We performed a retrospective analysis of 481 patients with breast cancer, aged ≥ 70 years, between 2010 and 2016. Of these, 302 patients underwent BCSNR and 179 underwent other, larger scope operations. Local recurrence rate, ipsilateral breast tumor recurrence (IBTR) rate, distant metastasis rate, breast-related death, disease-free survival (DFS), and overall survival (OS) were compared between the two groups. After a median follow-up of 60 months, no significant differences in local recurrence, distant metastasis rate, breast-related death, and DFS were noted. The OS was similar (P = 0.56) between the BCSNR group (91.7%) and other operations group (93.0%). The IBTR rate was considered low in both groups, however resulted greater (P = 0.005) in the BCSNR group (5.3%) than in other operations group (1.6%). BCSNR did not affect the survival of elderly patients with breast cancer with clinically negative axillary lymph nodes. IBTR was infrequent in both groups; however, there was a significant difference between the two groups. BCSNR is a feasible treatment modality for patients with breast cancer ≥ 70 years old with clinically negative axillary lymph nodes.

Radiomics features may contribute to increased diagnostic performance of MRI in the prediction of axillary lymph node metastasis. The objective of the study was to predict preoperative axillary lymph node metastasis in breast cancer using clinical models and radiomics models based on T2-weighted (T2W) dedicated axillary MRI features with node-by-node analysis. From August 2012 until October 2014, all women who had undergone dedicated axillary 3.0T T2W MRI, followed by axillary surgery, were retrospectively identified, and available clinical data were collected. All axillary lymph nodes were manually delineated on the T2W MR images, and quantitative radiomics features were extracted from the delineated regions. Data were partitioned patient-wise to train 100 models using different splits for the training and validation cohorts to account for multiple lymph nodes per patient and class imbalance. Features were selected in the training cohorts using recursive feature elimination with repeated 5-fold cross-validation, followed by the development of random forest models. The performance of the models was assessed using the area under the curve (AUC). A total of 75 women (median age, 61 years; interquartile range, 51–68 years) with 511 axillary lymph nodes were included. On final pathology, 36 (7%) of the lymph nodes had metastasis. A total of 105 original radiomics features were extracted from the T2W MR images. Each cohort split resulted in a different number of lymph nodes in the training cohorts and a different set of selected features. Performance of the 100 clinical and radiomics models showed a wide range of AUC values between 0.41–0.74 and 0.48–0.89 in the training cohorts, respectively, and between 0.30–0.98 and 0.37–0.99 in the validation cohorts, respectively. With these results, it was not possible to obtain a final prediction model. Clinical characteristics and dedicated axillary MRI-based radiomics with node-by-node analysis did not contribute to the prediction of axillary lymph node metastasis in breast cancer based on data where variations in acquisition and reconstruction parameters were not addressed.

PURPOSE: We studied the prognostic and predictive value of immunohistochemically detected occult tumor cells (OTCs) in lymph nodes and bone marrow aspirates obtained from node-negative breast cancer patients. All were classified as distant metastases-free using conventional staging methods. PATIENTS AND METHODS: A total of 484 patients with pT1-2N0M0 breast cancer and 70 with pT1-2N1M0 breast cancer and a single affected lymph node participated in our trial. Ipsilateral axillary lymph nodes and intraoperatively aspirated bone marrow were examined. All samples were examined for OTCs using monoclonal antibodies to cytokeratins 8, 18, 19. Immunohistological findings were correlated with other prognostic factors. The mean follow-up was 54 ± 24 months. RESULTS: OTCs were detected in 180 (37.2%) of 484 pT1-2N0M0 patients: in the bone marrow of 126 patients (26.0%), in the lymph nodes of 31 patients (6.4%), and in bone marrow and lymph nodes of 23 (4.8%) patients. Of the 70 patients with pT1-2N1MO breast cancer and a single involved lymph node, OTCs were identified in the bone marrow of 26 (37.1%). The ability to detect tumor cells increased with the following tumor features: larger size, poor differentiation, and higher proliferation. Tumors of patients with OTCs more frequently demonstrated lymph node invasion, blood vessel invasion, higher urokinase-type plasminogen activator levels, and increased PAI-1 concentrations. Patients with detected OTCs showed reduced disease-free survival (DFS) and overall survival (OAS) rates that were comparable to those observed in patients who had one positive lymph node. Multivariate analysis of prognostic factors revealed that OTCs, histological grading, and tumor size are significant predictors of DFS; OTCs and grading of OAS. CONCLUSION: OTCs detected by simultaneous immunohistochemical analysis of axillary lymph nodes and bone marrow demonstrate independent metastatic pathways. Although OTCs were significantly more frequent in patients with other unfavorable prognostic factors, they were confirmed as an independent prognostic factor for pT1-2N0M0, R0 breast cancer patients.

566 Background: This study measures the feasibility and accuracy of sentinel lymph node biopsy (SLNB) with triple-tracers (TT-SLNB) which combines carbon nanoparticles (CNS) with dual tracers of radioisotope and blue dye, hoping to achieve an optimized method of SLNB after neoadjuvant chemotherapy (NAC) in ycN0 breast cancer patients with pretreatment positive axillary lymph nodes. Methods: Clinically node-negative invasive breast cancer patients with pre-NAC positive axillary lymph nodes who received surgeries from November 2020 to January 2021 were included. CNS was injected at the peritumoral site the day before surgery. Standard dual-tracer (SD)-SLNs were defined as blue-colored and/or hot nodes, and TT-SLNs were defined as lymph nodes detected by any of hot, blue-stained, black-stained, and/or palpated SLNs. All patients received subsequent axillary lymph node dissection. Detection rate (DR), false-negative rate (FNR), negative predictive value (NPV) and accuracy of SLNB were calculated. Results: Seventy-six of 121 (62.8%) breast cancer patients converted to cN0 after NAC and received TT-SLNB. After NAC, 28.95% (22/76) achieved overall (breast and axilla) pCR. The DR was 94.74% (72/76), 88.16% (67/76) and 96.05% (73/76) for SLNB with single-tracer of CNS (CNS-SLNB), SD-SLNB, and TT-SLNB, respectively. The FNR was 22.86% (8/35) for CNS-SLNB and 10% (3/30) for SD-SLNB. The FNR of TT-SLNB was 5.71% (2/35), which was significantly lower than those of CNS-SLNB and SD-SLNB. The NPV and accuracy was 95.0% and 97.3% for TT-SLNB, respectively. Moreover, a significant relation was seen between the pretreatment clinical T classification and the DR of TT-SLNB (Fisher’s exact test, p= 0.010). Conclusions: TT-SLNB revealed ideal performance in post-NAC ycN0 patients with pretreatment node-positive breast cancers. The application of TT-SLNB reached a better balance between more accurate axillary evaluation and less intervention. Clinical trial information: ChiCTR2000039814. [Table: see text]

Background: Breast malignancies are the second most common cause of cancer-related mortality among women. As the size of the primary breast cancer increases, some cancer cells are shed into cellular spaces and transported via the lymphatic network of the breast to the regional lymph nodes, especially the axillary lymph nodes. Objective of the study was to determine the accuracy of USG and US-FNAC in detecting lymph node metastasis in a clinically lymph node negative CA Breast patient.Methods: This prospective study was conducted on 40 consecutive patients with biopsy proven breast cancer with clinically negative axilla, who had attending the OPD or IPD in our department of surgery, Swaroop Rani Nehru Hospital, Allahabad, during the period of 2014 to 2015. All of these patients were planned to undergo surgery (breast conservation or modified radical mastectomy with axillary clearance).Results: Sensitivity of the study = 97.77%, specificity = 25%, positive predictive value =92.01%, negative predictive value =50%, diagnostic accuracy =90%.Conclusions: Using axillary ultrasound and selective US-FNAC is a rapid, non-morbid method of staging the axilla in newly diagnosed breast cancer patients and should become a routine part of patient care because it can spare many patients particularly those who are undergoing axillary dissection.

Objective: To determine the diagnostic accuracy of axillary US as a preoperative investigation by comparing it with the histology outcome of nodal status. Methods: This validation analysis was conducted in Mater Misericordia university hospital, Dublin Ireland form Feb 2007 to Feb 2015. All female patients with impalpable axillary lymph node and histology proven unifocal breast cancer between ages 18 to 75 years were included. Patients with the diagnosis of breast cancer were followed with Ultrasound imaging and results in Picture Archiving and communication system (PACS) and histology was confirmed using the patient center data base in both preoperative and postoperative course of breast cancer, including both sentinel lymph nodes and axillary lymph nodes. Results: A total of 625 patients had axillary ultrasound (US) to assess the preoperative axillary nodal status with mean age of 56±12 years. cN0 was diagnosed in 469 (75%) cases, cN1 in 136 (21.8%) cases and cN2 in 20 (3.2%) cases. After negative axillary ultrasound cN0 pathology shows positive pN2 and pN3 disease in 14 (2.9%) cases with the NPV of 97.01%. Axillary ultrasound had shown cN1 disease in 136 cases with the pathology outcome of pN2 and pN3 in 41 (30.14%) cases with the negative predictive value (NPV) of 69.85%. The overall sensitivity and specificity of the axillary US in detection of the positive node was 51.6% and 92.8% with PPV of 82.69% and NPV of 74.2%. Conclusion: Axillary US is a useful modality for screening of breast cancer patients. The negative US findings exclude the presence of advanced nodal disease. However, it cannot accurate distinguish between pN1 and pN2 or pN3 nodal disease. Keywords: Axillary ultrasound, Axillary lymph nodes, Breast cancer.

Purpose With the increased use of breast ultrasound for different indications, sonographically abnormal axillary lymph nodes are not a rare finding. We examined clinical and imaging characteristics in correlation with pathological reports of the sonographic guided biopsies to assess the yield of needle biopsy of these nodes. Methods Clinical, imaging and pathology data were collected for 171 consecutive patients who underwent sonographic guided needle biopsy of an abnormal lymph node between 2008 and 2013. Malignancy rates were examined for different clinical settings: palpable axillary mass, previous history of breast cancer, findings suggestive of a systemic disease, and those with a breast finding of low suspicion or an incidental abnormal axillary lymph node. Patients with newly diagnosed breast cancer were excluded. Results Twelve patients (7%) were found to have a malignancy on their axillary lymph node biopsy. Malignancy rates increased with age, and varied with clinical presentation: Axillary mass (8, 26%); history of breast cancer (2, 11%); systemic disease (0%) and breast finding of low suspicion or incidental abnormal lymph node on screening (1, 1%). Low rates of malignancy were found when the cortex was <6 mm (1, 0.8%). The most important imaging finding associated with malignancy was lack of a preserved hilum, in which case almost a third (10, 29%) of the biopsies were malignant. Only 1 of 89 women with a breast finding of low suspicion or an incidental abnormal axillary lymph node was found to have malignancy. In this case the lymph node had no hilum. Conclusions In women without breast cancer, a highly suspicious breast mass or an axillary mass, more stringent criteria should be used when evaluating an abnormal axillary lymph node on sonography, as the malignancy rates are very low (1%).
