Purpose: An increasing proportion of patients (> 30%) with node-positive breast cancer will obtain an axillary pathologic complete response after neoadjuvant chemotherapy (NAC). If sentinel node (SN) biopsy (SNB) is accurate in this setting, completion node dissection (CND) morbidity could be avoided.
Patients And Methods: In the prospective multicentric SN FNAC study, patients with biopsy-proven node-positive breast cancer (T0-3, N1-2) underwent both SNB and CND.
Objective: The aims of our study were to determine the frequency of malignancy after surgical excision of biopsy-proven lobular carcinoma in situ (LCIS) or atypical lobular hyperplasia (ALH) lesions, to assess any difference between pure LCIS and pure ALH lesions regarding their radiologic presentation and the malignancy upgrade rate after surgical excision, and to evaluate the outcome of lesions that were not excised surgically but were followed up.
Materials And Methods: Radiologic and pathologic records of 14,435 imaging-guided needle biopsies of the breast performed between 2004 and 2008 in three different institutions were retrospectively reviewed. A total of 126 patients (0.
Objective: The purpose of our study was to retrospectively evaluate the clinical, imaging, and pathologic findings of breast hemangiomas in 16 patients.
Conclusion: A mass displaying an oval or lobular shape with well-circumscribed or microlobulated margins on mammography and sonography, and in a superficial location, should alert the radiologist to the possible diagnosis of hemangioma. Imaging-guided biopsy appears sufficiently reliable to rule out any malignant or premalignant component and to avoid a surgical excision if doing so is clinically appropriate.
Objective: The purpose of this study was to review the sonographic features of breast cancer gene BRCA1- and BRCA2-associated breast carcinomas in comparison with "sporadic" breast carcinomas and benign breast masses.
Methods: Sonograms of 233 breast masses, including 33 BRCA-associated malignant masses (BRCA1, 15; BRCA2, 18), 148 sporadic malignant masses, and 52 benign masses, were reviewed by consensus by 2 radiologists according to American College of Radiology Breast Imaging Reporting and Data System (BI-RADS) terminology.
Results: Most of the sporadic and BRCA1-and BRCA2-associated cancers displayed an irregular shape (91.
Objective: The aim of this pilot/feasibility study was to describe the experience of women presenting with a suspicious mammogram who are waiting for a breast biopsy and to identify those at risk for distress.
Methods: Participants (n=25) were interviewed at two time points: immediately after being put on the waiting list (T1) and again immediately before their biopsy approximately 6 weeks later (T2). Self-report measures of distress and coping were used.
