Two studies reported in The New England Journal of Medicine showed that the addition of bevacizumab (Avastin) to neoadjuvant chemotherapy significantly increased the pathologic complete response rate in women with HER2-negative breast cancer. In one study, from the German Breast Group, the benefit...
The Six1 gene is a key regulator of embryonic development that requires interaction with the Eya family of proteins (Eya1-4) to activate transcription of genes involved in neurogenesis, myogenesis, and nephrogenesis. Overexpression of Six1 and Eya is observed in a number of cancers. In breast...

Two large collaborative genomics projects are producing new and sometimes surprising findings about what makes breast cancers tick—information that may ultimately be applied to improve clinical outcomes. In a special session titled “Genome Data for the Masses: Presentation of TCGA and ICGC Breast...
Women with atypical breast lesions have approximately a 5% to 11% risk of developing breast cancer within 5 years, depending on histology, and this risk can be reduced with chemoprevention, according to a presentation at the 2011 San Antonio Breast Cancer Symposium.1 Investigators tracked the...
The best advice I received after getting a diagnosis of stage I invasive lobular carcinoma in my left breast was from my radiologist, who told me, “Remember, be your own best advocate.” Those words have stayed with me through my 6-year struggle with breast cancer and its aftermath. Extraordinary...
Patient and tumor characteristics can stratify women with breast cancer and a BRCA mutation into groups having different risks of contralateral disease, which may help tailor follow-up, suggests a study of more than 5,000 women in the Netherlands. Confirming findings of other studies, the study...
A benefit of the oral bisphosphonate clodronate when used as adjuvant therapy for early breast cancer may depend on factors such as the endpoint assessed and patient age, suggests the randomized B-34 trial conducted by the National Surgical Adjuvant Breast and Bowel Project (NSABP). The trial,...

Results from the American College of Surgeons Oncology Group (ACOSOG) Z0011 trial, which found no benefit for completion axillary nodal dissection in patients with breast cancer involving one to two positive sentinel nodes,1 have led to changes in breast cancer management, though points of...
The days of attending the Breast Cancer Symposium, just quietly listening to useful lectures, and then going home are over. In recent years, the meeting’s sponsors and planners have worked to make the 3-day gathering far more interactive and as intimate as a meeting with 1,500 attendees can be....
The American College of Surgeons Oncology Group (ACOSOG) Z1031 trial examined the effect of neoadjuvant aromatase inhibitor therapy on clinical response and breast-conservation rates in postmenopausal women with estrogen receptor (ER)-rich stage II or III breast cancer. An update of the surgical...
The human genome contains a large variety of endogenous retroviral sequences (approximately 8% of the genome). Although most of these are highly defective, the human endogenous retrovirus type K (HERV-K) family shows conservation of apparently intact retroviral genes and is transcriptionally active ...
The cytokine pigment epithelium–derived factor (PEDF) is downregulated in brain metastases of breast cancer by approximately 14-fold compared with primary breast tumors, suggesting that promoting its expression might inhibit metastatic spread. Normal breast epithelial cells express high levels of...
The National Comprehensive Cancer Network (NCCN) Clinical Practice Guidelines in Oncology have become the most widely used guidelines in oncology practice. The Guidelines cover 97% of all patients with cancer and are continually updated by expert panels. The 2012 Guidelines include some completely...
The events surrounding the labeling of bevacizumab (Avastin) have been well covered since last November when the FDA withdrew the drug’s accelerated approval as a treatment for metastatic breast cancer. However, the controversy initiated a debate over the value of endpoints in clinical trials in...
Women with ductal carcinoma in situ (DCIS) treated with breast-conserving surgery “continue to have diagnostic and invasive breast procedures in the conserved breast over an extended period,” according to a study reported in the Journal of the National Cancer Institute. “The estimated 10-year...
In 2002, it was thought that menopausal hormone therapy using estrogen alone increases breast cancer risk, although not as quickly as combined estrogen plus progestin. Current thinking about estrogen alone is that it reduces breast cancer risk. This is just one example of changing concepts about...
Among older women with invasive breast cancer and treated with lumpectomy, brachytherapy compared with whole-breast irradiation was associated with a decreased likelihood of long-term breast preservation and an increased likelihood of complications, but no difference in overall survival, according...
It has been shown that a field of genetically altered but histologically normal tissue extends 1 cm or more from the margins of human breast tumors. The characteristics of this field are not fully understood, although it is clear that the molecular alterations in affected cells could provide...

As the world’s most common cancer among women, and the most likely reason around the globe that a woman will die of cancer, breast cancer affects countries at all economic levels. Despite the common misconception that breast cancer is primarily a problem of high-income countries, the majority of...
I’ve never had a normal mammogram screening. There was always something suspicious the test picked up: macrocalcifications in one breast 1 year and a cyst in the other breast the next year. Over a period of 3 years, I had six tissue biopsies, all benign for cancer. So when I flunked another...
The impact of soy consumption on breast cancer diagnosis and outcome has remained of concern to clinicians and researchers for the past 20 years. Although studied extensively in epidemiologic studies as well as lab and animal research, no medical consensus on soy’s effects has emerged. Many studies ...
Tumor cell recognition by natural killer (NK) cells is mediated by the interaction of activating and inhibitory NK cell receptors with ligands expressed on the tumor cells. NK cells also express adhesion molecules that facilitate formation of the immune synapse with tumor targets. Maria Libera...
According to the first national study looking at racial disparity in breast cancer mortality rates at the city level in the United States, societal factors—especially poverty and residential segregation—are resulting in the unnecessary deaths of five black women every day—more than 1,700 deaths a...
Dune Medical Devices announced that an FDA Advisory Panel voted 10 to 1 in favor of Dune’s MarginProbe System for use in breast cancer surgery, as an adjunct to current standard methods of intraoperative surgical margin assessment.
