Younger, early breast cancer patients often undergo unnecessary staging, imaging procedures

Presented at a poster session at the 2013 CTRC-AACR San Antonio Breast Cancer Symposium by Carlos Barcenas, M.D., assistant professor in MD Anderson’s Breast Medical Oncology, the study is the first to look at the issue of over-use of staging procedures, including imaging and tumor markers in the diagnosis setting, specifically in younger, early-stage breast cancer patients. Over-testing and unnecessary procedures extends beyond cancer care across the healthcare continuum. …

Physicians who prefer hospice care for themselves more likely to discuss it with patients

"Having timely discussions with terminally-ill cancer patients to establish goals for end-of-life care is important to maximize the quality of patient care. But by and large we’re not doing a good job at having these discussions early on," says lead author Garrett Chinn, MD, MS, of the Massachusetts General Hospital Division of General Medicine. "We know that patients facing terminal illness often wish to spend their remaining days at home, surrounded by loved ones. Since end-of-life care in the U.S…

Antihormone therapy anastrozole may provide new option for breast cancer prevention

About 80 percent of women diagnosed with breast cancer in the United States each year have tumors with high levels of hormone receptors. These tumors are fueled by the hormone estrogen. Anastrozole is a drug that prevents the body from making estrogen, and it has been used to treat postmenopausal women with hormone receptor-positive breast cancer for more than 10 years. "We initiated the International Breast Cancer Intervention Study II (IBIS-II) Prevention trial to investigate whether anastrozole can be used effectively to prevent breast cancer," said Jack Cuzick, Ph.D., chairman of the IBIS-II Steering Committee. …

Misunderstanding of palliative care leads to preventable suffering

The authors say for palliative care to be used appropriately, clinicians, patients, and the general public must learn the fundamental differences between palliative care and hospice care, a distinction that is not well-known. Seven in ten Americans describe themselves as "not at all knowledgeable" about palliative care, and most health care professionals believe it is synonymous with end-of-life care. While both are intended to relieve suffering, hospice care provides care for people in the last phases of an incurable disease so that they may live as fully and comfortably as possible. Palliative care focuses on helping patients get relief from symptoms caused by serious illness and is appropriate at any age or stage in a serious illness…

Deep sequencing of breast cancer tumors predict outcomes after single dose of therapy

Results showed that through deep genome sequencing, a reduction in the most commonly mutated genes in breast cancer could be observed after just one dose of preoperative therapy. Deep sequencing is a process that involves sequencing the same region multiple times to identify mutations within tumors that have an importance in cancer evolution. These new findings were presented during the 2013 San Antonio Breast Cancer Symposium. "Genomics is the new frontier of cancer research, and this study shows that we may be able to accurately determine what treatment methods will and will not be effective for individual patients after just one dose of medicine," said Lyndsay Harris, MD, study investigator and Director, Breast Cancer Program, UH Seidman Cancer Center and Professor of Medicine at Case Western Reserve University School of Medicine. …

Newly discovered gene interaction could lead to novel cancer therapies

In the study, recently published in the online version of the journal Cancer Research, Fisher’s team found that forced expression of MDA-7/IL-24 (melanoma differentiation associated gene-7/interlukin-24) stimulates SARI (suppressor of AP-1, induced by interferon) expression in what is known as an autocrine/paracrine loop, which ultimately causes cancer cells to undergo a form of cell suicide known as apoptosis. Autocrine/paracrine loops occur when the expression of a particular gene or its encoded protein causes cells to secrete molecules that bind to surface receptors and force the expression of more of the same protein in an ongoing cycle…

Partially blocking blood vessels’ energy source may stop cancer growth, blindness, other conditions

"Our findings reveal a new strategy to block blood vessel growth in various pathological conditions by depriving them of energy and building blocks necessary for growth," says senior author Dr. Peter Carmeliet of the University of Leuven and the Vesalius Research Center, VIB in Belgium. While current strategies to thwart pathological blood vessel formation focus primarily on inhibiting vascular endothelial growth factor (VEGF), this latest research centers around blocking glycolysis, the process that endothelial cells rely on for generating most of the energy they need to multiply and migrate. …

Systems medicine paves way for improved treatment for leukemia patients

A multi-disciplinary team of researchers at the Institute for Molecular Medicine Finland, FIMM, and the Helsinki University Central Hospital has developed a novel individualized systems medicine (ISM) strategy which enables selection of potentially effective cancer therapies for individual patients. Furthermore, this strategy helps in understanding and predicting drug resistance and may pave a path for individualized optimization of patient therapies in the clinic for various types of cancers. Many novel targeted drugs have been introduced to the clinic for cancer therapy, often guided by genomic clues on disease pathogenesis. Clinical treatment of cancer patients is, however, challenged by the fact that genomics is often not informative in selecting therapies to individual patients…
