Herceptin and HER2+ breast cancer

Using Herceptin with chemotherapy, instead of after, clearly improves treatment of women with HER2+ breast cancer, and should be the new standard of care, says a Mayo Clinic researcher who led what is regarded to be a key clinical trial determining the best use of Herceptin.

Patients using Herceptin and chemotherapy at the same time had a relative 25 percent reduction in the risk of recurrence of cancer or death, compared with women who used Herceptin after chemotherapy, says Edith Perez, M.D., chair, North Central Cancer Treatment Group (NCCTG) Breast Committee and a breast cancer researcher at the Mayo Clinic campus in Jacksonville, Fla. She presented the findings of the study at the Cancer Therapy & Research Center-American Association for Cancer Research (CTRC-AACR) 2009 San Antonio Breast Cancer Symposium.

These findings may have global implications for women being treated for HER2+ breast cancer, which makes up 20 percent to 25 percent of all cases, Dr. Perez says.
