BACKGROUND Sentinel lymph node (SLN) mapping has become the standard of care for axillary staging in women with early-stage breast cancer. The purpose of the study was to investigate the hypothesis that nonvisualization of SLN on lymphoscintigraphy (LSG) predicts a subset of patients at risk of having a substantial burden of axillary tumor as evidenced by(More)
Core needle biopsy (CNB) is used to sample both mammographically and ultrasound detected breast lesions. A diagnosis of ductal carcinoma in situ (DCIS) by CNB does not ensure the absence of invasive cancer upon surgical excision and as a result an upstaged patient may need to undergo additional surgery for axillary nodal evaluation. This study evaluates the(More)
The effect of epigenetic modifications on the regulation of gene expression and the concomitant relationship to human diseases has become a key area of biological research in recent years. Studies have suggested that there is direct correlation between epigenetic modifications, such as histone methylation, histone acetylation and DNA methylation, and gene(More)
Rates of implant failure, wound healing delay, and infection are higher in patients having radiation therapy (RT) after tissue expander (TE) and permanent implant reconstruction. We investigated pretreatment risk factors for TE implant complications. 127 breast cancer patients had TE reconstruction and radiation. For 85 cases of bilateral TE reconstruction,(More)
854 Background: Pregnancy-associated breast carcinoma is defined as breast cancer diagnosed either during pregnancy or one year post partum. Pregnancy may delay diagnosis and/or therapy and potentially worsen outcomes. METHODS We evaluated the presentation and survival outcomes of 47 consecutive patients presenting with breast cancer during or <1 year(More)
BACKGROUND A single center retrospective chart review was performed examining the ability of a novel radiofrequency probe (Margin Probe; Dune Medical Devices, Caesarea, Israel) for intraoperative margin assessment to reduce the number of reexcisions in breast-conserving surgery. METHODS Reexcision rates were evaluated in one-hundred and twenty consecutive(More)
