Exemestane alone and exemestane following tamoxifen, are equally appropriate treatment options, according to results from TEAM, the first trial prospectively powered to test the superiority of five years of aromatase inhibitors compared with a specific sequential strategy in postmenopausal women with endocrine-sensitive breast cancer.
Dr. Otis W. Brawley took a courageous stand late last week, one he has taken many times before, but which had until then gone all but unnoticed. Responding to a Journal of the American Medical Association article detailing the scientific and medical limitations of breast and prostate screening, the chief medical officer of the American Cancer Society acknowledged that “in the case of some screening for some cancers, modern medicine has overpromised.”
Removal of the primary breast tumor in women whose cancer has already metastasized can have a significant effect on their survival, Dutch researchers have found. Dr. Jetske Ruiterkamp, a surgical resident from the Jeroen Bosch Hospital, Den Bosch, The Netherlands, working under the supervision of Dr. Miranda Ernst, told Europe’s largest cancer congress, ECCO 15/ESMO 34, in Berlin that her research meant that women who were diagnosed at a late stage of the disease could expect to survive longer.
Data from the Austrian Breast and Colorectal Cancer Study Group (ABCSG)-24 study presented at the joint 15th ECCO and 34th ESMO congress in Berlin, show that adding capecitabine (Xeloda) to anthracycline- and taxane-containing regimens prior to surgery completely eradicated the tumor in 24% of women with HER2-positive or HER2-negative early breast cancer. This is an impressive finding since the proportion of women achieving total tumor eradication with standard chemotherapy for HER2-positive or HER2-negative early breast cancer is less than 20% (range = 6%–18%).
Breast cancer is the most common newly diagnosed malignancy among American women. In 2008, an estimated 182,460 new cases of invasive breast cancer, and an additional 67,770 cases of in situ cancer were diagnosed. Approximately 40,480 women will die from breast cancer each year.
Bayer HealthCare Pharmaceuticals and Onyx Pharmaceuticals, Inc, announced the full results from their first collaborative group-sponsored randomized, double-blind, placebo-controlled phase II trial showing that sorafenib (Nexavar) tablets in combination with the oral chemotherapeutic agent, capecitabine (Xeloda), significantly extended progression-free survival in patients with advanced breast cancer.
ORLANDO-Breast cancer experts gathered at ASCO 2009 to answer five important questions about anthracyclines, taxanes, HER2-positive disease, trastuzumab (Herceptin), and anti-VEGF agents. Their key message for adjuvant therapy: One size does not fit all. The participants were:
Long-term tamoxifen use among breast cancer survivors is associated with a more than fourfold increased risk of ER-negative cancer in the contralateral breast, according to the investigators at Seattle’s Fred Hutchinson Cancer Research Center.
Hologic, Inc, recently announced the US Food and Drug Administration (FDA) cleared the Company’s 510K application for the MammoSite ML radiation therapy system. With its multilumen design, this new device gives radiation oncologists the ability to shape the radiation dose for typical cases and treat patients who are otherwise not appropriate candidates for traditional brachytherapy.
Chadha et al are to be commended for their excellent review of repeat breast-conservation therapy after isolated in-breast local failures. We will briefly review several important points already made by the study authors.
Breast-conservation therapy (BCT) is a well-characterized treatment for early-stage breast cancer that has been studied for decades. The risk of local recurrence following BCT for invasive breast cancer ranges from 8.8% to 14.3% at 20 years.
October marks National Breast Cancer Awareness month, now in its 25th year, a time to contemplate important advances and milestones as well as future research needs.
In the US, breast cancer is the most common invasive cancer in women, with more than 200,000 diagnosed with the disease each year.
In about 30% of U.S. women who receive a diagnosis of early breast cancer, the cancer will progress to metastatic disease, but in the developing world, most cancer is initially diagnosed at an advanced stage, said William Gradishar, MD, director of medical breast oncology at the Robert H. Lurie Comprehensive Cancer Center, at Northwestern University, Chicago.
Thanks to the tireless efforts of the breast cancer community, October and breast cancer are tightly bound with the ubiquitous pink ribbon. But the awareness campaign places a heavy emphasis on prevention, detection, and early diagnosis. For women with metastatic breast cancer, there is a sense that the “pink parade” has intentionally passed them by even though an estimated 465,000 annual deaths from breast cancer worldwide occur because of metastatic disease.
Breastfeeding reduces breast cancer risk among women with a family history of breast cancer, according to a study. Observational studies suggest a relationship between lactation and premenopausal breast cancer risk.
Final results from a phase II study of an enhanced version of Herceptin upheld the emerging benefits previously seen with this novel approach in HER2-positive breast cancer.
Current evidence does not support the routine use of breast MRI in women with newly diagnosed breast cancer, according to Monica Morrow, MD, chief of the breast service, department of surgery, at Memorial Sloan-Kettering Cancer Center.
Researchers suggest routine screening of breast cancer patients for disruptions.
Newly published data in the August 20, 2009, issue of The New England Journal of Medicine affirm 5-year upfront use of letrozole (Femara) following surgery as an optimal treatment approach vs tamoxifen for postmenopausal women with early-stage breast cancer (hormone-receptor positive).
Black women who are diagnosed with breast cancer have a higher probability of dying from the disease than white women, regardless of their estrogen receptor status, according to research from the National Cancer Institute (NCI).

They are supposed to be the standard bearers of the body’s defense against disease. But when it comes to cancer, some macrophages are traitors, helping rather than fighting the enemy. They attach to metastatic tumor cells, as they do to other threats. But rather than destroying metastatic cells, these macrophages enable their growth.
WASHINGTON, DC-Two separate new drug applications, for the treatment of relapsed ovarian cancer and advanced breast cancer, failed to win the approval of FDA’s Oncologic Drugs Advisory Committee.
In a follow-up study, Christopher I. Li, MD, PhD, and colleagues have reconfirmed their finding that migraine headaches are associated with a lower risk of breast cancer.
For every 1000 women aged 40 to 74 years who participated in screening, 3.9 diagnosed with breast cancer died compared with 5.0 among those who did not participate. The absolute benefit in terms of reduced deaths due to mammography screening, therefore, is about one in 1000.
