New finding points to potential options for attacking stem cells in triple-negative breast cancer
Date:2/17/2014

the cancer stem cells, thereby blocking metastasis. Bortezomib is currently approved for treatment of the blood cancer multiple myeloma.

This team previously showed that IL6 can stimulate breast cancer stem cells in HER2-positive breast cancers and they are designing a clinical trial which uses an IL6 blocker. The new research suggests that adding bortezomib to the IL6 inhibitor may be a way to target stem cells in triple-negative breast cancer.

"Now that we unveiled how inflammation is regulated in triple-negative breast cancer, we expect that our studies can be translated into the clinic. The drugs used to block these chemical messengers are already approved for the treatment of rheumatoid arthritis and other inflammation-related diseases, which should facilitate their use in cancer," says study author Hasan Korkaya, Ph.D., assistant professor at the Georgia Regents University Cancer Center.

More laboratory testing is needed before a clinical trial can begin. The researchers also suspect that this pathway may apply to other cancers as well and are investigating that further.

Breast cancer statistics: 235,030 Americans will be diagnosed with breast cancer this year and 40,430 will die from the disease, according to the American Cancer Society
