Benign vascular lesions of the breast diagnosed by core needle biopsy do not require excision.

Aims: Surgical excision of all benign vascular lesions of the breast identified by core needle biopsy has been recommended in the past to rule out a more serious lesion. In this study we investigated the clinical, radiological and pathological findings in patients diagnosed with a benign vascular lesion at our institution to assess whether excision may be spared for lesions without atypia.

Methods And Results: We searched the electronic medical record for patients with a vascular lesion of the breast diagnosed between 2000 and 2015.

Breast carcinoma with an Oncotype Dx recurrence score <18: Rate of distant metastases in a large series with clinical follow-up.

Background: A 21-gene expression assay (Oncotype DX recurrence score [RS]) that uses reverse transcriptase-polymerase chain reaction is used clinically in patients with early-stage, estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast carcinoma (ER+/HER2- BC) to determine both prognosis with tamoxifen therapy and the usefulness of adding adjuvant chemotherapy. Use of the assay is associated with reductions in overall chemotherapy use. The current study examined the treatments and outcomes in patients with low RS.

Breast intraductal papillomas without atypia in radiologic-pathologic concordant core-needle biopsies: Rate of upgrade to carcinoma at excision.

Background: The surgical management of mammary intraductal papilloma without atypia (IDP) identified at core-needle biopsy (CNB) is controversial. This study assessed the rate of upgrade to carcinoma at surgical excision (EXC).

Methods: This study identified women with a CNB diagnosis of intraductal papilloma without atypia or carcinoma at a cancer center between 2003 and 2013.

Radial Scar at Image-guided Needle Biopsy: Is Excision Necessary?

Optimal management of a lesion yielding radial scar (RS) without epithelial atypia on breast biopsy is controversial. In this single-institution study spanning 17 years, 53 patients with this biopsy diagnosis were evaluated in terms of clinical, radiologic, and pathologic features and outcomes. RSs were categorized as either "incidental" or as the "targeted" lesion according to defined criteria.
