#1 Buh-bye, breast cancer

Keith Knutson, Ph.D.

Can breast cancer be prevented with a vaccine? Mayo Clinic immunology researcher Keith Knutson, Ph.D, thinks so. And he thinks it will happen during his lifetime. He also thinks it will be possible to prevent breast cancer from recurring by stimulating the immune system.

In the first-ever clinical trial of its kind, Jared Ausnehmer had stem cells from his own bone marrow injected into his heart to treat hypoplastic left heart syndrome. The therapy surpassed all expectations. Two months later, he was cleared to return to normal life and his favorite sport, basketball.

Death, ultimately, is inevitable. But for patients at Mayo Clinic Health System in Mankato’s Hospice Program, the process of dying is becoming more bearable for themselves and their families as a result of research studies aimed at understanding more.

"Even though it's the end of life, it's incredibly important for patients to have closure and resolution, and feel good about their life's story and what they're leaving with other people," says Greg Kutcher, M.D. "We need to better understand how to do that."

Oncology patients usually receive chemotherapy along with surgery to treat bile duct cancer. However, recently Mayo Clinic researchers found that patients who receive chemotherapy before surgery to remove their cancer were more likely to live longer than patients who received chemotherapy after surgery.

McArdle's sign is a distinctive muscle weakness that affects patients with spinal cord disease and researchers are looking at it as a possible indicator of multiple sclerosis. The namesake of the "sign," M.J. McArdle, was a professor of neurology in London, and one of his patients with advanced multiple sclerosis needed to extend his neck and tip his head back to maintain a steady gait.

#8 Why doctors might need to go back to 6th grade

When patients are feeling tired and sick, it can be difficult to understand discharge instructions, particularly when they’re written in complicated medical language. Mayo researchers are working to change that by studying ways to improve readability and comprehension through the use of simpler language and other teaching tools.

For patients who have chronic lymphocytic leukemia, fighting off a serious infection can be difficult and often is just not possible. And a team of Mayo researchers is starting to find out why. They hope that by understanding how bone marrow function is impaired in chronic lymphocytic leukemia patients, they can develop unique strategies to boost bone marrow function or find alternate treatments that do not block or modify marrow function.
