Positive axillary status can be found in these patients. This study sought to identify clinicopathological factors associated with upstaging and axillary metastasis in patients preoperatively diagnosed with DCIS by CNB.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>This study identified 604 patients (cT1\u20103N0M0) with preoperative diagnosis of pure DCIS by CNB who had undergone axillary evaluation from August 2006 to December 2015 at Fudan University Shanghai Cancer Center (FUSCC). Predictors of upstaging and axillary lymph nodes metastasis were analyzed, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of all 604 patients, 121 (20.03%) and 193 (31.95%) patients were upstaged to DCIS with microinvasion (DCISM) and invasive breast cancer (IBC). Positive axillary lymph nodes were identified in 41 (6.79%) patients. Predictors of upstaging included tumor size on ultrasonography (&gt;2\u00a0cm) (OR 1.786, <jats:italic>P<\/jats:italic>\u00a0=\u00a0.002) and ER+HER2+ status (OR 1.874, <jats:italic>P<\/jats:italic>\u00a0=\u00a0.022) in multivariate analysis. Factors associated with axillary lymph nodes metastasis included tumor size on pathology (OR 2.336, <jats:italic>P<\/jats:italic>\u00a0=\u00a0.038) and number of lesions (OR 3.354, <jats:italic>P<\/jats:italic>\u00a0=\u00a0.039) in multivariate analysis. In addition, upstaging on final pathology had a significant influence on axillary lymph nodes status (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Axillary evaluation was recommended in patients with larger tumor size (&gt;2\u00a0cm), multifocal lesions or ER+HER2+ status. Despite of a 51.98% upstaging rate, the rate of axillary metastasis in these patients was relatively low, supporting the omission of axillary evaluation in selected patients with low risk of upstaging or axillary metastasis.<\/jats:p><\/jats:sec>","DOI":"10.1002\/cam4.2623","type":"journal-article","created":{"date-parts":[[2019,10,29]],"date-time":"2019-10-29T09:24:36Z","timestamp":1572341076000},"page":"7586-7593","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Axillary evaluation is not warranted in patients preoperatively diagnosed with ductal carcinoma in situ by core needle biopsy"],"prefix":"10.1002","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4540-6859","authenticated-orcid":false,"given":"Jing","family":"Si","sequence":"first","affiliation":[{"name":"Department of Breast Surgery Fudan University Shanghai Cancer Center Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rong","family":"Guo","sequence":"additional","affiliation":[{"name":"Department of Breast Surgery Fudan University Shanghai Cancer Center Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naisi","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Breast Surgery Fudan University Shanghai Cancer Center Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bingqiu","family":"Xiu","sequence":"additional","affiliation":[{"name":"Department of Breast Surgery Fudan University Shanghai Cancer Center Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qi","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Breast Surgery Fudan University Shanghai Cancer Center Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weiru","family":"Chi","sequence":"additional","affiliation":[{"name":"Department of Breast Surgery Fudan University Shanghai Cancer Center Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiong","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Breast Surgery Fudan University Shanghai Cancer Center Shanghai China"},{"name":"Collaborative Innovation Center for Cancer Medicine Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,10,29]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.7314\/APJCP.2014.15.1.55"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.breast.2012.06.012"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cursur.2004.09.011"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.22435"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10549-006-9289-6"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1245\/s10434-010-1438-9"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.4048\/jbc.2011.14.4.301"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.9337"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/his.12550"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.5306\/wjco.v7.i2.258"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjsurg.2010.09.032"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2016.71.0947"},{"key":"e_1_2_9_14_1","unstructured":"National Comprehensive Cancer Network.NCCN Clinical practice guidelines in oncology.2017.
