BACKGROUND: Papillary breast lesions comprise a spectrum of histopathologic diagnoses ranging from benign papillomas to papillary carcinomas. There is ongoing controversy regarding the management of papillary lesions diagnosed by core needle biopsy (CNB). Some authors advocate observation of papillary lesions when the CNB is benign, while others recommend surgical excision of all papillary lesions. The current study assessed the adequacy of CNB in evaluating papillary breast lesions. METHODS: A search of the pathology database at our institution identified 122 papillary lesions diagnosed by CNB. The study population consisted of 71 papillary lesions that were subsequently surgically excised. RESULTS: Of the 71 papillary lesions excised, 8 were malignant, 16 were atypical, and 47 were benign at the time of CNB. Of the 47 papillary lesions thought to be benign, 13 (28%) revealed atypia and 4 (9%) revealed malignancy upon surgical excision. Of the 13 atypical papillary lesions on CNB, 7 lesions (54%) were associated with malignancy upon excision. Slightly over half the upgrades were due to finding atypia or malignancy in the tissue surrounding the papillary lesion. The total rate of upgrades from the CNB diagnosis to the excisional diagnosis was 38%. CONCLUSIONS: When a core biopsy of a papillary lesion is encountered, there is a strong likelihood of discovering atypia or malignancy in the index lesion or in close proximity. Therefore, surgical excision should be performed to avoid missing a malignancy and to allow for accurate breast cancer risk assessment that can impact survival and decisions regarding chemoprevention

BACKGROUND: Population-based overall patterns of surgical management of the axilla in women with operable breast cancer during the era of adoption of sentinel lymph node biopsy (SLNB) were studied. METHODS: Women with operable breast carcinoma residing in 14 geographic areas of the Surveillance, Epidemiology, and End Results (SEER) cancer registries (1998-2004, n=239,661) were assessed for axillary surgical patterns of care. RESULTS: Use of SLNB increased from 11 to 59%. Use of no axillary surgery decreased from 14 to 6.6%. In pathologic node-negative women, use of axillary lymph node dissection (ALND) decreased from 94 to 36%. Independent factors most associated with failure to receive SLNB included diagnosis year (2000: 62%; 2004: 29%), surgery (mastectomy: 64%; breast-conserving surgery: 36%), tumor size (T3: 71%; T2: 56%; T1: 40%), age (>or= 70 years: 50%; <70 years: 45%), grade (high: 42%; low: 38%), urbanity (non-large metropolitan area: 49%; large metropolitan area: 42%), and, by quartile, poverty (highest: 47%; lowest: 35%), and white-collar employment (lowest: 56%; highest: 47%). In pathologic node-positive women who had SLNB, failure to undergo completion ALND increased from 20% in 1998 to 32% in 2004. Patients with smaller, lower-grade tumors, and those with smaller size of nodal metastasis, lack of extracapsular extension, age >or= 70 years, increased linguistic isolation, African-American or Hispanic race/ethnicity, and white-collar employment were less likely to undergo completion ALND. CONCLUSIONS: Management of the axilla changed dramatically during the period of rapid adoption of SLNB. Patterns of care suggest both appropriate and inappropriate selection for SLNB and ALND

OBJECTIVE: We evaluated the benefit of placing a marker under sonographic guidance at the time of localization to aid in identifying mammographically occult lesions within the specimen at the time of surgical excision and to evaluate margin status. MATERIALS AND METHODS: We reviewed 135 sonographically guided needle localizations performed on mammographically occult lesions. Imaging during the localization procedure, marker placement, and specimen radiographs were reviewed, and the findings were correlated with the histopathologic findings. RESULTS: Of the 135 mammographically occult lesions, 77 were localized without marker placement and 58 with marker placement. The 58 localizations with marker placement were for masses with a mean lesion size of 9 mm. Specimen radiography of these lesions showed a marker within the specimen in 56 cases (97%) and visualization of the lesion in only seven cases (12%). Specimen radiography of localizations without marker placement showed visualization of the lesion in 18 cases (23%). Of the 11 malignant lesions (19%) localized with marker placement, none had a positive inked margin, but five (46%) had close margins necessitating reexcision. Of the 26 malignant lesions (34%) localized without marker placement, two (8%) had a positive inked margin, and eight (31%) had close margins necessitating reexcision. CONCLUSION: At needle localization of breast lesions, marker placement under sonographic guidance is beneficial because it enables immediate confirmation of accurate surgical removal of the localized lesion at surgical excision. Use of marker placement, however, does not reduce the percentage of cases with close margins necessitating reexcision

A parental diagnosis of cancer can have a powerful psychological effect on a child. Although responses vary significantly with age and the individual, children often react with uncertainty fear, guilt and anxiety It is up to the parents and the healthcare team to maintain awareness of this growing issue and respond accordingly Parents can minimize their child's distress by maintaining open communication throughout the diagnosis, treatment, and recovery processes. Furthermore, an informative, timely, and supportive response from a multidisciplinary healthcare team can successfully reduce stressors and guide the child through the experience. As cancer becomes a more chronic issue, it is becoming imperative that medical physicians address its psychological impacts on the patient and family in order to both improve the quality of life during illness and reduce the long-term negative consequences for years after.

CONTEXT: Both atypical lobular hyperplasia (ALH) and lobular carcinoma in situ (LCIS) have traditionally been considered to be risk factors for the development of invasive carcinoma and are followed by close observation. Recent studies have suggested that these lesions may represent true precursors with progression to invasive carcinoma. Due to the debate over the significance of these lesions and the small number of cases reported in the literature, the treatment for lobular neoplasia diagnosed by percutaneous core biopsy (PCB) remains controversial. OBJECTIVE: To review our experience with pure LCIS or ALH diagnosed by PCB and correlate the radiologic findings and surgical excision diagnoses to develop management guidelines for lobular neoplasia diagnosed by PCB. DESIGN: We searched the pathology database for patients who underwent PCB with a diagnosis of either pure LCIS or ALH and had subsequent surgical excision. We compared the core diagnoses with the surgical excision diagnoses and the radiologic findings. RESULTS: Thirty-eight PCBs with a diagnosis of ALH (18 cases) or LCIS (20 cases) were identified. Carcinoma was present at excision in 1 (6%) of the ALH cases and in 2 (10%) of the LCIS cases. In summary, 8% (3/38) of PCBs diagnosed as lobular neoplasia (ALH or LCIS) were upgraded to carcinoma (invasive carcinoma or ductal carcinoma in situ) at excision. CONCLUSIONS: Surgical excision is indicated for all PCBs diagnosed as ALH or LCIS, as a significant percentage will show carcinoma at excision
