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.

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.

196 Background: An important benefit of neoadjuvant chemotherapy (NAC) is the increase in breast-conserving surgery. At present the response of axillary lymph node metastases to chemotherapy cannot be accurately assessed. Therefore axilla-conserving therapy is not yet a benefit. We aimed to assess a new surgical method to evaluate the axillary response: the MARI procedure, which stands for Marking of the Axillary lymph node with Radioactive Iodine seeds. Methods: Prior to NAC, proven tumor-positive axillary lymph nodes were marked with a Iodine-125 seed. After NAC, the marked lymph node was selectively removed with the use of a gamma-detection probe. A complementary axillary lymph node dissection was performed to assess whether pathological response in the marked node was indicative for the pathological response in the additional lymph nodes. Results: Tumor-positive axillary lymph nodes were successfully marked with Iodine-125 seeds in 68 patients. The marked lymph node (MARI-node) was surgically detected and selectively removed after NAC in all patients. The pathological response to chemotherapy in the MARI-node was indicative for the overall response in the additionally removed lymph nodes. In 47 patients the MARI-node contained residual disease (n=45 macrometastasis, n= 2 ITC). Thirty-five of them had macro- or micro metastases in the complementary axillary lymph node dissection specimen. In 21 patients the MARI-node was tumor negative. In 2 patients a macro metastasis was found in the additionally removed nodes, in 2 patients ITC were found and in the remaining 17 patients no residual tumor was found in the additionaly removed lymphnodes. (false negative rate of the MARI procedure: 9.5%). Conclusions: This study shows that marking and selectively removing metastatic lymph nodes after NAC is feasible. The tumor-response in the marked lymph node may be used to tailor further axillary treatment, and herewith enabling axilla-conserving surgery after neoadjuvant chemotherapy.

We report a case of an elderly woman, presenting with vesicouterine fistula and enlarged axillary lymph nodes. She had been diagnosed with cervical squamous cell carcinoma (SCC) in April 2015, for which she had received brachytherapy and concurrent chemoradiation therapy. The presence of enlarged axillary lymph nodes raised a suspicion for breast cancer with axillary metastases, but the bilateral mammograms did not show any discrete lesion in both breasts. The biopsy from axillary lymph node showed metastatic SCC, with block positivity for P16, confirming the origin from known cervical primary. Axillary lymph nodes are the least likely to be involved by tumours arising in the pelvis, as the lymphatic drainage of this region goes directly to the systemic circulation via the para-aortic lymph nodes and thoracic ducts. A complete clinical history is essential in such cases, to avoid misdiagnosis. Positron emission tomography CT helps in this regard.

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%).
