Cutting chemo for PLResearchers say they have found a gene that could cut chemo for some breast cancer patients. According to the European study, published in New England Journal of Medicine, a test called MammaPrint that examines 70 genes can determine whether a patient is high or low risk for recurrence. Researchers studied a group of 1,500 women with breast cancer that had not spread to the lymph nodes.  One group of women considered high risk based on the genetic testing received chemo. The other group, deemed low risk, did not. After 5 years, scientists say survival rates for the two groups were similar. The women who did not receive chemo had a 95 percent survival rate.

According to the findings, nearly half of women with breast cancer who are classified as high risk based on clinical factors may not need chemo. Researchers say, however, the choice to include chemotherapy as part of a treatment regimen remains an individualized decision between doctors and patients. To read more on this study, click here.
