After it was reported that 25 labs in Quebec incorrectly identified markers for hormone therapy in 15% to 20% of breast cancer patients, the Canadian Breast Cancer Network called for urgent action to implement systemic changes in national standards for breast cancer testing.

Cell surface coating may play a major role in the spread of breast cancer to the brain, according to a study out of Memorial Sloan-Kettering Cancer Center in New York. Three genes-COX2, HB-EGF, and ST6GALNAC5-have been found to mediate the metastasis of breast cancer to the brain, reported lead author Joan Massagué, PhD, and colleagues (Nature online, May 6, 2009)

As breast cancer remains the most commonly diagnosed cancer among women in the United States, there has been a decline in breast cancer–related mortality for the past 2 decades; this is likely related to diagnosis at an earlier stage and the availability of more effective treatment regimens.

Researchers at Chicago’s Northwestern University reported that Abraxane (nab-paclitaxel) nearly doubled progression-free survival compared with Taxotere (docetaxel) when used as first-line treatment in patients with metastatic breast cancer. William Gradishar, MD, led the phase II, open-label, randomized clinical study of 300 patients with previously untreated metastatic, stage IV breast cancer.

Carlos L. Arteaga, MD, will be presented with the Gianni Bonadonna Breast Cancer Award at the 2009 ASCO Breast Cancer Symposium in San Francisco. Dr. Arteaga, who is a professor of medicine and cancer biology at Vanderbilt University School of Medicine and director of the breast cancer research program of the Vanderbilt-Ingram Cancer Center in Nashville, will deliver the Bonadonna lecture at the symposium.

Two new studies reported at this year’s ASCO meeting demonstrated the effect of a new class of targeted therapy called poly (ADP-ribose) polymerase (PARP) inhibitors on traditionally difficult-to-treat breast cancers-so-called “triple-negative” breast cancer and BRCA1/2-deficient breast cancers.

Many women have turned to natural forms of hormone replacement for menopause since learning that conventional hormone replacement therapy (HRT) may increase their risks of breast cancer and other health problems. Most women have assumed that “natural” or “bioidentical” HRT is safer than conventional HRT. However, recent research has shown that this is not the case and that, in fact, the risks are probably similar.

The American Civil Liberties Union and the Public Patent Foundation at Benjamin N. Cardozo School of Law filed a lawsuit charging that patents on two human genes associated with breast and ovarian cancer stifle research that could lead to cures and limit women’s options regarding their medical care.
