Every year, over 25,000 people need to have a stem cell transplant to treat their blood cancer. While this can cure their cancer, it also weakens the immune system. A weak immune system is a problem because it means people get more infections and can experience other complications like their cancer coming back. When we are healthy, our gut is filled with helpful bacteria. During cancer treatment, many patients lose these helpful bugs. Patients who lose the good bacteria after they have a transplant, don’t recover as well as patients who keep their helpful bugs. These good bacteria are needed for strong immune system recovery. We are working in the lab to find new ways to support healthy bugs during cancer treatment. We think this will help the patients’ immune system. Having a healthy immune system means fewer infections and a longer life. If successful, this research could lead to new treatments that help patients feel better during their transplant, avoid infections, and live longer. In the future, we will run clinical trials in transplant patients, which will lead to new standard treatments.
