When DNA and medical tests disagree about breast cancer risk, which to believe?

When DNA and medical tests disagree about breast cancer risk, which to believe?

It's a dilemma more and more cancer patients will face as genetic testing becomes part of everyday health care: When a DNA test indicates low risk of a tumor spreading, but traditional tests show a high risk, which do you believe?According to a large European study of 6,693 patients published on Wednesday, many women with early breast cancer can safely believe the genetic test.Patients who skipped chemotherapy when a genetic test showed low risk of the cancer advancing but a traditional test suggested high risk were almost as likely to survive five years without the cancer recurring as those who had chemo.(The traditional tests look for cancer cells in lymph nodes and fast-dividing cells, for instance, and include demographic facts of life, such as being over 50.)

Genetic test may be able to predict need for chemotherapy in early-stage breast cancer

Genetic test may be able to predict need for chemotherapy in early-stage breast cancer

By Sally Robertson, BScPatients with early stage breast cancer who have a low genetic risk of disease recurrence may not need to have chemotherapy, report researchers.The findings come from a study that used a genetic test called MammaPrint to assess the risk of cancer recurrence in women with early-stage disease.The genetic markers that tumors carry vary from individual to individual and MammaPrint works by checking a 70-gene signature that predicts the likelihood of disease recurrence among such patients.As reported in the New England Journal of Medicine, Laura van't Veer (San Francisco Helen Diller Family Comprehensive Cancer Center) and colleagues used MammaPrint to genetically profile excised tumors from almost 6,700 patients with early-stage breast cancer.

Study of breast cancer treatment reveals paradox of precision medicine

Study of breast cancer treatment reveals paradox of precision medicine

A major study about the best way to treat early-stage breast cancer reveals that "precision medicine" doesn't provide unambiguous answers about how to choose the best therapy."Precision doesn't mean certainty," says David Hunter, a professor of cancer prevention at Harvard's T.H.Chan School of Public Health.That point is illustrated in a large study published Wednesday in the New England Journal of Medicine, involving decisions about chemotherapy.
