This talk consists of two parts. In the first, the present experimental bounds on the anomalous couplings of the gauge bosons, based mainly on the LEP and Tevatron experiments, are reviewed. In the second part, the theorem of helicity conservation (HC) is presented, which should be valid in either the Standard Model (SM) or MSSM, for any two-body process at high energies and fixed angles. The e...

CONTEXT Health care reform calls for increasing physician accountability and transparency of outcomes. Partial mastectomy is the most commonly performed procedure for invasive breast cancer and often requires reexcision. Variability in reexcision might be reflective of the quality of care. OBJECTIVE To assess hospital and surgeon-specific variation in reexcision rates following partial mastec...

Adequate surgical margins in breast-conserving surgery for breast cancer have traditionally been viewed as a predictor of local recurrence rates. There is still no consensus on what constitutes an adequate surgical margin, however it is clear that there is a trade-off between widely clear margins and acceptable cosmesis. Preoperative approaches to plan extent of resection with appropriate margi...

The primary administration of chemotherapy leads to a reduction in size of tumors, increasing the possibility of breast-conserving surgery in both locally advanced, inoperable and primary operable mamma carcinomas. This, however, increases the rate of local relapse and the rate of mastectomy over the course of the disease, even although the EUSOMA guidelines are not exceeded. Whether the pre-su...

Management of the axilla is controversial. There has never been a widely agreed means of balancing an understanding of nodal status as prognostic information, the need to prevent axillary recurrence and the wish to avoid treatment-related morbidity, particularly arm lymphoedema. Balancing these conflicting requirements is difficult, particularly as the results of previous trials of locoregional...

OBJECTIVE To study the clinical outcomes of patients with invasive or non-invasive breast cancer after breast conservation treatment. DESIGN Retrospective study. SETTING Clinical oncology department of a public hospital, Hong Kong. PATIENTS Two hundred and three patients who received postlumpectomy radiotherapy at the Pamela Youde Nethersole Eastern Hospital between January 1994 and June ...

PURPOSE To determine the frequency by which breast magnetic resonance imaging (MRI) provides information that influences the surgical management of patients with breast cancer. MATERIALS AND METHODS From August 2006 to December 2008, contrast-enhanced bilateral breast MRI was performed on 68 patients, all of whom exhibited highly suspicious imaging findings (BI-RADS category 4 or 5). Patients...

INTRODUCTION So called "extreme oncoplastic surgery" is emerging as a new promising concept in breast cancer surgery allowing successful breast conservation in selected patients with multicentric tumors. PRESENTATION OF CASE We report the case of a 48-year-old woman presenting with a multicentric breast cancer and successfully treated with an oncoplastic technique consisting in three radical ...

Breast cancer presenting as axillary adenopathy without radiographic or clinical breast abnormality is a rare entity accounting for less than 1% of all breast cancers.[1,2] In the past, extended searches for an extramammary site were conducted, but this extensive workup was unproductive and therefore not recommended.[3] Most authors currently advise that carcinoma found in an axillary node in a...
