The parameters and patterns evaluated on conventional ultrasound included short axis diameter (S), long axis\/short axis (L\/S) ratio, cortical thickness, resistive index (RI), lymph node (LN) morphology of greyscale ultrasound, hilum and vascular pattern. Meanwhile, enhancement pattern, wash-in time, time to peak (TP), maximum signal intensity, and duration of contrast enhancement were evaluated on CEUS. Univariate and multiple logistic regression analyses were performed to identify independent factors of ALN status. Three models (conventional ultrasound, CEUS, and combined parameters) were established. Receiver operating characteristic (ROC) curves were applied to evaluate the accuracy of the three predictive models.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results:<\/jats:title>\n                  <jats:p>On conventional axillary ultrasound, LN morphology and vascular pattern were independent factors in predicting metastatic ALNs. On CEUS, maximum signal intensity, duration of contrast enhancement, and TP were independent factors in predicting metastatic ALNs. When combining conventional ultrasound and CEUS features, five independent factors obtained from the conventional ultrasound and CEUS were associated with ALN status. ROC curve analysis showed that the use of CEUS markers combined with conventional ultrasound features (AUC = 0.965) was superior to the use of CEUS markers (AUC = 0.936) and conventional ultrasound features alone (AUC = 0.851).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion:<\/jats:title>\n                  <jats:p>Combining conventional ultrasound and CEUS features can enable discrimination of ALN status better than the use of CEUS and conventional ultrasound features alone.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Advances in knowledge:<\/jats:title>\n                  <jats:p>The axillary lymph node status in breast cancer patients impacts the treatment decision. Our ultrasonic data demonstrated that CEUS features of ALNs in breast cancer patients could be image markers for predicting ALN status. Combining conventional ultrasound and CEUS features of ALNs can improve specificity discrimination of ALN status better than the use of CEUS and the conventional ultrasound features alone, which will help the treatment planning optimization.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1259\/bjr.20200874","type":"journal-article","created":{"date-parts":[[2020,9,25]],"date-time":"2020-09-25T20:04:56Z","timestamp":1601064296000},"source":"Crossref","is-referenced-by-count":24,"title":["Adding contrast-enhanced ultrasound markers to conventional axillary ultrasound improves specificity for predicting axillary lymph node metastasis in patients with breast cancer"],"prefix":"10.1093","volume":"94","author":[{"given":"Li-Wen","family":"Du","sequence":"first","affiliation":[{"name":"Department of Ultrasound, The First Affiliated Hospital of Nanjing Medical University , No. 300 Guangzhou Road, Nanjing 210029 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hong-Li","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hai-Yan","family":"Gong","sequence":"additional","affiliation":[{"name":"Department of Ultrasound, The First Affiliated Hospital of Nanjing Medical University , No. 300 Guangzhou Road, Nanjing 210029 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li-Jun","family":"Ling","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shui","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cui-ying","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Ultrasound, The First Affiliated Hospital of Nanjing Medical University , No. 300 Guangzhou Road, Nanjing 210029 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min","family":"Zong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2020,12,22]]},"reference":[{"key":"2024050215450747200_b1","doi-asserted-by":"crossref","first-page":"847","DOI":"10.1016\/S0140-6736(16)31392-7","article-title":"The global burden of women's cancers: a grand challenge in global health","volume":"389","author":"Ginsburg","year":"2017","journal-title":"Lancet"},{"key":"2024050215450747200_b2","doi-asserted-by":"crossref","first-page":"394","DOI":"10.3322\/caac.21492","article-title":"Global cancer statistics 2018: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries","volume":"68","author":"Bray","year":"2018","journal-title":"CA Cancer J Clin"},{"key":"2024050215450747200_b3","doi-asserted-by":"crossref","first-page":"e351","DOI":"10.1016\/S1470-2045(13)70590-4","article-title":"Novel techniques for sentinel lymph node biopsy in breast cancer: a systematic review","volume":"15","author":"Ahmed","year":"2014","journal-title":"Lancet Oncol"},{"key":"2024050215450747200_b4","doi-asserted-by":"crossref","first-page":"3670","DOI":"10.1200\/JCO.2006.08.8013","article-title":"Doctor, what are my chances of having a positive sentinel node?
