Since the discovery of BRCA1 and BRCA2, investigators have sought to determine whether the presence of a germline mutation independently influences the outcome of a breast cancer diagnosed in a woman with an inherited mutation. The question is highly relevant to an unaffected woman with a mutation, ...

The U.S. Food and Drug Administration (FDA) has approved the first generic version of capecitabine (Xeloda), an oral chemotherapy agent used in the treatment of metastatic colorectal cancer and breast cancers. Teva Pharmaceuticals USA has gained FDA approval to market generic capecitabine in 150...
Pathologic complete response as assessed surgically after neoadjuvant treatment is being touted by some researchers as a stand-alone endpoint justifying early drug approval for breast cancer. They argue that it provides a more efficient means of testing the value of agents that might be useful in...
German investigators reported at the 2013 Breast Cancer Symposium in San Francisco that an abridged magnetic resonance imaging (MRI) protocol can accurately detect cancers among women whose mammographic screenings were negative.1 MRI, therefore, may reveal the type of tumor that mammography...

Overestimating the risk that cancer in one breast will affect the other breast may cause many young women with breast cancer to choose contralateral prophylactic mastectomy even though most know it does not clearly improve survival. In a survey of 123 women who were diagnosed with cancer in one...
I know it sounds strange, but being diagnosed with cancer was one of the best things to have happened to me. I don’t mean to diminish the traumatic experience of hearing the words, “You have breast cancer.” That was over 11 years ago, and I’m still reeling from the diagnosis and its aftereffects....

More than 90% of women undergoing mammography screening could not give an accurate estimate of their personal risk of developing breast cancer, according to results of a large survey reported at the 2013 ASCO Breast Cancer Symposium and featured in a premeeting presscast. The survey showed that a...
The good news about HER2-positive breast cancer is that recurrent disease is plummeting, owing to the impact of adjuvant trastuzumab [Herceptin]. Hopefully, first-line metastatic treatment is becoming a thing of the past,” said Harold Burstein, MD, PhD, of Dana-Farber Cancer Institute, Boston....

Bickell, MD, MPH, of Mount Sinai School of Medicine in New York, and colleagues who conducted a randomized trial among 374 women...
The impact of hormone replacement therapy on breast cancer risk varies according to the patient’s to race/ethnicity, body mass index, and breast density. An analysis of 1,642,824 screening mammograms with 9,300 breast cancer cases in postmenopausal women aged 45 years or older found that hormone...
“Varying risk factor associations between inflammatory and noninflammatory breast cancer suggest a distinct etiology for [inflammatory] breast cancer,” according to a study in the Journal of the National Cancer Institute. High body mass index was shown to increase risk of inflammatory breast cancer ...

Results of the phase III TH3RESA trial show that the antibody-conjugate ado-trastuzumab emtansine (Kadcyla), formerly known as T-DM1, extends progression-free survival in women with advanced HER2-positive breast cancer that progressed on two or more previous HER2-directed therapies including...
Only nodal status and tumor size provided statistically significant prognostic information for predicting recurrences 5 to 10 years after diagnosis for postmenopausal women with early estrogen receptor–positive breast cancer enrolled in the monotherapy arms of the ATAC (Arimidex, Tamoxifen, Alone...
For women with BRCA1 or BRCA2 mutations who choose to have salpingo-oophorectomy to reduce their risks of ovarian and breast cancer, also choosing to have a hysterectomy is “reasonable but not required,” noted Noah D. Kauff, MD, Director of the Ovarian Cancer Screening and Prevention Program and...
Recent years have witnessed much heated debate about the benefits of breast cancer screening and optimal screening strategies. Unlike with mammography, no randomized data are available to determine whether screening with magnetic resonance imaging (MRI) reduces mortality from breast cancer....
Annual screening for breast cancer with magnetic resonance imaging (MRI) has been found to be cost-effective in women aged 30 to 60 years who are BRCA1 or BRCA2 carriers or who have a 50% chance of being a carrier, and such screening is recommended in these women by many authorities. It is unclear...
Sentinel lymph node surgery provides reliable nodal staging information and is associated with less morbidity than axillary lymph node dissection in patients with clinically node-negative (cN0) breast cancer. The American College of Surgeons Oncology Group (ACOSOG) Z1071 (Alliance) trial examined...
The adjuvant use of bisphosphonates in breast cancer continues to yield seemingly contradictory data despite a sound biologic basis and smaller pilot studies suggesting that dampening bone turnover with bisphosphonates can lessen the bone reservoir of micrometastases.1,2 Early adjuvant trials with...
