What is Evidence-Based Health Care?

“Evidence-based health care” means health care that is based on the best scientific research, combined with what’s important to patients, and doctors’ knowledge and experience. People are usually surprised to learn that not all medical care is based on the best evidence, but unfortunately, it’s true. Why is evidence-based health care so important? Much of […]

What are the different types of research studies?

Comparative Effectiveness Research (CER) Comparative effectiveness research (CER) is a direct comparison of existing options available for treating a particular medical condition. It may compare similar treatments, such as competing drugs, or it may analyze very different interventions, such as surgery and drug therapy. It may also compare the effectiveness of how and when health […]

Relative Risk vs. Absolute Risk

We often hear news reports that something has been found to reduce the risk of breast cancer or reduce the risk of dying from breast cancer. These reports are often misleading because they use numbers representing relative risk reductions. Absolute risk reduction is what really matters, which is often much lower, and often not reported. […]

Outcome Measures or Endpoints for Clinical Trials

NBCC Says: The appropriate selection of outcome measures for cancer trials is a focus of ongoing debate. While recognizing that proper outcome selection is influenced by the specific design characteristics and resource limitations of the study, the National Breast Cancer Coalition believes that endpoints should be chosen in a manner that maximizes the usefulness and […]

Mammography Screening

Does Mammography Screening Save Lives? NBCC Position NBCC believes that there is insufficient evidence to recommend for or against universal screening mammography in any age group of women. Women who have symptoms of breast cancer such as a lump, pain or nipple discharge should seek a diagnostic mammogram. The decision to undergo screening for asymptomatic […]

Anthracyclines

Does the evidence still support their use in the first-line treatment of breast cancer? The anthracycline debate continues. In 2007, the National Breast Cancer Coalition took the position that “for the vast majority of women with breast cancer, anthracycline-based chemotherapy is no more effective and has the potential for more serious toxicities than other known […]

“Rewiring” Cells to Treat Triple Negative Breast Cancer

Breast cancer cells can be “rewired” to make them more sensitive to chemotherapy, according to a new study published in the journal Cell. Rather than giving targeted therapy and chemotherapy simultaneously, researchers at the Massachusetts Institute of Technology (MIT) pretreated the cancer cells with targeted therapy, making them more susceptible to DNA-damaging chemotherapy. Dr. Michael […]
