For a malignant tumor to form, cancer cells must evade the immune system's attack. Numerous studies have already shown that cancer spreads particularly aggressively if there is an unfavorable balance between suppressing and active immune cells in the tumor microenvironment. “But we didn't...
As reported by Solin et al in Journal of Clinical Oncology, 12-year results from the ECOG-ACRIN E5194 trial indicate that among women with ductal carcinoma in situ (DCIS) with low-risk clinical and pathologic characteristics, surgical excision without radiation therapy was associated with...
In an analysis reported in the Journal of the National Cancer Institute, Ligibel et al found that body mass index (BMI) at diagnosis was independently prognostic for recurrence-free and overall survival in women with early-stage node-positive breast cancer who received doxorubicin,...
For younger women with early-stage, noninherited breast cancer on one side, a unilateral mastectomy leads to a slightly higher quality of life and lower costs over the next 20 years compared with contralateral prophylactic mastectomy, according to new study results presented at the 2015 Annual...
In a systematic review and network meta-analysis reported in JAMA Oncology, Fujii et al found that sequential anthracycline-cyclophosphamide and taxane (AC-T) appears to be the most effective adjuvant regimen in early-stage breast cancer in terms of association with overall survival and toxicity....

Although most patients with breast cancer are cured after treatment, in about one in five patients, the cancer will recur, returning either to the same place as the original tumor or metastasizing to other parts of the body. Now, researchers have taken an important step toward understanding why...
Overall survival data from a phase II study, reported in the Journal of Clinical Oncology by Ellis et al, suggest a benefit of first-line fulvestrant (Faslodex) vs anastrozole in postmenopausal women with estrogen receptor–positive advanced breast cancer. The study protocol was amended to...
Adjuvant radiation therapy may be omitted for elderly women with estrogen receptor–positive, early-stage breast cancer who receive hormone therapy. Limited data exist to guide treatment decision-making for elderly women with triple-negative breast cancer. As some findings thus far have shown...

Women who are obese have a higher risk and a worse prognosis for breast cancer, but the reasons why remain unclear. A Cornell study published by Seo et al in Science Translational Medicine suggests that obesity changes the consistency of breast tissue in ways that predispose an individual to tumor...
Scientists have developed a blood test for breast cancer that may be able to identify which patients will suffer a relapse after treatment, months before tumors are visible on hospital scans. The test may uncover small numbers of residual cancer cells that have resisted therapy by detecting cancer...
Concerns about fertility kept one-third of young women with breast cancer surveyed in a recent study from taking tamoxifen, despite its known benefit in reducing the risk of breast cancer recurrence. In addition, the study found fertility concerns led one-quarter of women who started...
A study by researchers at Sweden's Karolinska Institutet is reportedly the first to suggest that cells in the tumor blood vessels contribute to a local environment that protects the cancer cells from tumor-killing immune cells. The results, published by Hong et al in the Journal of the...
Women who have inherited mutations in the BRCA1 or BRCA2 gene are more likely to develop breast cancer or ovarian cancer, especially at a younger age. Approximately 5% of women with breast cancer in the United States have mutations in BRCA1 or BRCA2, based on estimates in non-Hispanic white women. ...
The phase III NSABP B-40 (NRG Oncology) trial showed that the addition of bevacizumab (Avastin) to docetaxel-based neoadjuvant chemotherapy improved pathologic complete response rate, the primary endpoint, in patients with early HER2-negative breast cancer. In a report of secondary outcomes in The...

Researchers have shown that magnetic resonance imaging (MRI) can detect the earliest signs of breast cancer recurrence and fast-growing tumors through detecting micrometastases, breakaway tumor cells with the potential to develop into dangerous secondary breast cancer tumors elsewhere in the body....
In an analysis reported in the Journal of Clinical Oncology, Park et al found that most of the improvement in breast cancer–specific mortality observed over time in the United States is not explained by tumor size or estrogen receptor status in women aged < 70 years, suggesting a major...
Chemotherapy prolongs life for older adults with most types of cancer, but for women with breast cancer over age 80, the chances of survival with chemotherapy alone are significantly lower than in younger patients, according to a study led by researchers from the University of Texas...
