Mastectomies that preserve the nipple and an envelope of breast skin are as safe as more radical operations for qualifying early-stage breast cancer patients, according to a meta-analysis and systematic literature review presented at the American Society of Breast Surgeons 16th Annual Meeting.1...
Bilateral prophylactic mastectomy may ease cancer-related anxiety for patients at high risk of breast cancer, but it does very little to contain the costs. A study presented at the American Society of Breast Surgeons 16th Annual Meeting found that bilateral prophylactic mastectomy was not...
Taking additional tissue circumferentially around the cavity left by partial mastectomy (“cavity shave margins”) cut the rate of positive margins by nearly 50% and the rate of reexcision for margin clearance by more than 50% compared with standard partial mastectomy with or without the surgeon...
I had been watching a lump in my left breast for signs of cancer for 10 years, from around the time I was 21. Screening tests had failed to find any tissue abnormality, and my doctor said I was too young to have cancer, so I wasn’t overly concerned. But when I noticed the lump getting bigger in...
The quality of mammography images has markedly improved over the past few decades. However, the quality of the interpretation of mammograms remains variable. That said, more than 38 million mammograms are performed annually in the United States. So said Diana Buist, PhD, Senior Scientific...
Anastrozole was found to be at least as safe and effective as tamoxifen in preventing breast cancer recurrence in women with ductal carcinoma in situ, in the large NSABP B-35/SWOG-35 study.1 Among all women in the trial, however, the 10-year breast cancer–free interval rates were higher in women...
Results are now in for the phase III MARIANNE trial. Although ado-trastuzumab emtansine (formerly known as T-DM1, Kadcyla) proved noninferior to trastuzumab (Herceptin) plus a taxane in the first-line metastatic breast cancer setting, it performed no better than the standard of care.1 “T-DM1 and...
I've been fortunate to be strong and healthy for most of my life. In fact, there is no history of any serious illness in my family, which is why I was so unprepared to hear the words “You have breast cancer” 5 years ago. Not only was the diagnosis foreign to me, I had no idea what chemotherapy and...
Kaufman and colleagues recently reported findings of a phase III trial comparing eribulin (Halaven) vs capecitabine in patients with advanced breast cancer who had previously received anthracycline and taxane therapy,1 and a review of their study appears in this issue of The ASCO Post. Although...
Eribulin (Halaven) currently is indicated in the United States for treatment of patients with metastatic breast cancer who previously received at least two chemotherapy regimens for metastatic disease and an anthracycline and a taxane in either the adjuvant or metastatic setting. Its approval was...
BOLERO-1—reviewed in this issue of The ASCO Post—is the next installment in a series of randomized trials evaluating the addition of everolimus (Afinitor) to standard therapy in metastatic breast cancer.1 The initial evaluation of everolimus in the HER2-positive metastatic setting looked extremely...
In the phase III BOLERO-1 trial, reported in The Lancet Oncology, Sara A. Hurvitz, MD, of the University of California, Los Angeles, and colleagues found that the addition of the mTOR inhibitor everolimus (Afinitor) to trastuzumab (Herceptin)/paclitaxel did not significantly increase...

After coping with breast cancer for more than a decade, it is difficult for me to put into words exactly how grateful I am to all the doctors, nurses, and researchers whose efforts have kept me alive for all these years. And not just alive, but thriving. A routine mammogram had discovered two...
For breast cancer patients with robust family histories, medical oncologists should be testing not only for BRCA1/2 mutations, but also for large duplications and deletions as well as for PALB2 mutations. “These [findings] have proven utility in testing breast cancer patients,” said Louise E....
Two separate retrospective studies have further refined our understanding of the respective contributions of surgery and radiotherapy in the treatment of breast cancer. However, these studies are not definitive, and “gold standard” trials are needed to arrive at definitive recommendations. Both...
As reviewed in this issue of The ASCO Post, Chlebowski and colleagues1 reported differing patterns of breast cancer risk during or after hormonal therapy with estrogen plus progestin2 or estrogen alone,3 in an analysis of two Women’s Health Initiative (WHI) trials. This recent update on risk...
In an analysis of Women’s Health Initiative trials reported in JAMA Oncology, Rowan T. Chlebowski, MD, PhD, of Harbor-UCLA Medical Center, and colleagues found differing patterns of breast cancer risk among women receiving menopausal hormone therapy with estrogen plus progestin or estrogen alone.1...
A study of screening mammography across U.S. counties found that “the clearest result of mammography screening is the diagnosis of additional small cancers” but without a “concomitant decline in the detection of larger cancers, which might explain the absence of any significant difference in the...
Women diagnosed with ductal carcinoma in situ have a low risk of dying of breast cancer, according to an observational study looking at data from 108,196 women diagnosed with ductal carcinoma in situ between 1988 and 2011.1 The breast cancer–specific mortality rate for these women was 1.1% at 10...
In a study reported in JAMA Oncology, Steven A. Narod, MD, FRCPC, of Women’s College Research Institute, Women’s College Hospital, and the University of Toronto, and colleagues found that the risk of breast cancer mortality was elevated in patients with ductal carcinoma in situ compared with the...
Male breast cancer is an uncommon disease, although the incidence has increased over the past couple of decades. As with many other “orphan” diseases, male breast cancer is understudied, especially in randomized controlled trials. Although it shares similarities with female breast cancer, some...
The Early Breast Cancer Trialists’ Collaborative Group (EBCTCG) continues its practice of being a lighthouse, shedding its beacon of light on the vast ocean of breast cancer research through the publication of two large, individual patient level–data meta-analyses on the management of women with...

A prospective validation study of a 21-gene expression assay showed that treatment with endocrine therapy alone in women with hormone receptor–positive, HER2-negative breast cancer who had a low recurrence risk score resulted in low risk of recurrence. All patients included in the study were...
Magnetic resonance imaging (MRI) screening of women at average risk for breast cancer achieved a mean additional cancer yield of 15.8 cases per 1,000 women, greatly surpassing yields for supplemental digital breast tomosynthesis (1.25 per 1,000) or supplemental ultrasound (4.1 per 1,000). The...
Given that BRCA1 and BRCA2 mutation carriers have an estimated 40% to 85% lifetime risk of breast cancer and an increased risk of developing contralateral breast cancer, risk reduction in this population remains essential. According to a study presented at the 2015 Breast Cancer Symposium, use of...
The long-awaited first results are in from the TAILORx study, showing that patients with early breast cancer considered at low risk for recurrence can forgo chemotherapy and be treated with endocrine therapy alone.1 “Women with axillary node-negative, estrogen receptor–positive, HER2-negative...
Several studies have addressed the risks and benefits of ovarian suppression during chemotherapy for breast cancer in women of childbearing age. A new meta-analysis of randomized trials found that it prevented premature ovarian failure and was associated with a higher number of pregnancies post...
A multivariable analysis of clinical factors associated with tamoxifen use among premenopausal women with hormone receptor–positive breast cancer showed that fertility preservation was a significant factor and “the only predictor of both noninitiation and early cessation” of tamoxifen. “Among...
Although genetic testing has not turned up any inherited mutations that might explain the number of cancers that have plagued my immediate family, over the past 15 years, I have lost my father, aunt, and sister to the disease. In 2001, my husband, Wayne, died of acute promyelocytic leukemia, and...
In metastatic HER2-negative breast cancer, several trials have shown that the addition of the anti–vascular endothelial growth factor (VEGF) monoclonal antibody bevacizumab (Avastin) to different chemotherapy regimens significantly improved response rates and progression-free survival by various...
The phase III National Surgical Adjuvant Breast and Bowel Project (NSABP) B-40 (NRG Oncology) trial showed that the addition of bevacizumab (Avastin) to docetaxel + anthracycline-based neoadjuvant chemotherapy improved pathologic complete response rate, the primary endpoint, in patients with early...
Molecular categorization of tumors with immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) has become a critical component in the diagnosis and treatment of breast cancer, improving outcomes by assigning the most appropriate therapy to specific tumor pathways. According to a...
Breast tumors that recur appear to have a different genetic profile than those that do not, and they often demonstrate targetable mutations, according to the largest study of genetic sequencing of breast cancer tissue to date.1 This finding was presented at the 2015 European Cancer Congress. “We...
The reactions to the updated breast cancer screening guideline from the American Cancer Society (ACS) have been many, varied, and not consistently favorable but not surprising to Kevin C. Oeffinger, MD, who chaired the ACS panel that issued the guideline. Breast cancer screening “is an area that...
Not only is breast cancer among the most common cancers in women, but it is also one of the most common causes of premature death. Rates of death from the disease vary widely around the world, reflecting variations in risk, screening, and access to highest quality treatment. Although female gender...
