Measuring certain hormone levels could help determine a woman’s risk for breast cancer and add a key factor to current risk-prediction models, according to investigators from Harvard Medical School. Their new study results were presented at the American Association for Cancer Research (AACR) Annual ...
I read with interest the article, “Breast Cancer Vaccines for Primary Prevention Move Toward Clinical Use,” which appeared in the December 15th issue of The ASCO Post (page 28). However, information presented regarding the National Breast Cancer Coalition’s (NBCC’s) Artemis Project for a breast...
Among patients with locally advanced or metastatic estrogen receptor–positive breast cancer, fulvestrant (Faslodex) given at 500 mg “is associated with a 19% reduction in risk of death and a 4.1-month difference in median overall survival compared with fulvestrant 250 mg,” according to final...
Components of the phosphatidylinositide 3-kinase/mammalian target of rapamycin (PI3K/mTOR) pathway are deregulated in many human cancers, with about 30% of breast cancers harboring PIK3CA gene mutations. Emerging research shows that these mutations may render estrogen receptor alpha-positive tumors ...
Emerging research is suggesting that outcomes from neoadjuvant chemotherapy may be correlated with two genetic mutations that are common in breast cancer—PIK3CA and TP53. Their presence may affect response to treatment, and mutational shift after treatment may affect survival, according to studies...
The achievement of a pathologic complete response in patients with triple-negative breast cancer was boosted by the addition of carboplatin to a standard neoadjuvant chemotherapy regimen, and by the addition of veliparib, an investigational oral PARP inhibitor, plus carboplatin to a standard...
“If women are to truly participate in the decision of whether or not to be screened [for breast cancer using mammography], they need some quantification of its benefits and harms,” asserted H. Gilbert Welch, MD, MPH, Professor of Medicine, and Honor J. Passow, PhD, Instructor, at The Dartmouth...

Elevated circulating tumor cells were prognostic for survival but did not pan out as a marker for switching after one cycle of chemotherapy in patients with metastatic breast cancer. The phase III Southwest Oncology Group (SWOG) S0500 clinical trial, presented at the 2013 San Antonio Breast Cancer...
Ramucirumab added to first-line docetaxel failed to improve progression-free survival in patients with metastatic breast cancer in the large, randomized, placebo-controlled ROSE/TRIO-12 trial.1 An interim analysis of overall survival showed no advantage for the addition of ramucirumab. This study,...

The optimal time interval between surgery and initiation of adjuvant chemotherapy for early-stage breast cancer is not well established. Although most physicians aim to initiate adjuvant chemotherapy within a few weeks of surgery, clinical factors may cause delay. The influence of delay on relapse...
In a study reported in the Journal of Clinical Oncology, de Melo Gagliato et al from The University of Texas MD Anderson Cancer Center, Houston, assessed the association between time to adjuvant chemotherapy and survival in breast cancer patients.1 They found that delay of therapy is associated...

In 1999, Kornelia Polyak, MD, PhD, of the Dana-Farber Cancer Institute, received a Career Development Award from the Conquer Cancer Foundation for her project, “Isolation of Tumor Suppressor Genes Inactivated in DCIS of the Breast.” “The Career Development Award got me started,” she said. “When...
Zoledronic acid does not improve outcomes in patients with early breast cancer who do not have a full response to neoadjuvant anthracycline/taxane–based chemotherapy, according to results of the Neo-Adjuvant Trial Add-On (NATAN) study presented at the 2013 San Antonio Breast Cancer Symposium.1 A...
The addition of bevacizumab (Avastin) to adjuvant chemotherapy did not improve invasive disease-free survival or overall survival in patients with high-risk HER2-positive breast cancer in the large randomized phase III BETH trial. Although not specifically designed to answer this question, BETH...
There may be an immunogenic phenotype in breast cancer that could benefit from immune modulation as part of treatment, according to results from studies that correlated high levels of tumor-infiltrating lymphocytes with both pathologic complete responses and long-term outcomes. Studies presented at ...
Analysis of data from 20,560 women undergoing mastectomy for breast cancer found that breast reconstruction use “increased from 46% in 1998 to 63% in 2007 (P< .001), with increased use of implants and decreased use of autologous techniques over time (P < .001),” according to a report...
Pathologic complete response to neoadjuvant therapy has been proposed as a surrogate endpoint for long-term clinical benefit in breast cancer. The U.S. Food and Drug Administration (FDA) established the international Collaborative Trials in Neoadjuvant Breast Cancer (CTNeoBC) working group to...
Although cancer survival rates among pediatric and older adult patients continue to rise, survival rates for adolescents and young adults (AYAs), defined by the National Cancer Institute as those between the ages of 15 and 39, have remained stagnant for decades. In breast cancer especially, AYAs...
Preclinical models have suggested that cancer stem cells play a role in tumor recurrence and metastasis following adjuvant therapy, and Max S. Wicha, MD, and his research team are deciphering the mechanisms by which this might happen. A true understanding of cancer stem cells will have important...
