ClinConnect Summary
The Chemo-Gut Probiotic Trial for Cancer Survivors is a study designed to see if taking probiotics—beneficial bacteria that can help with digestion—can improve gastrointestinal problems like belly pain and mental health issues such as fatigue and depression in people who have finished cancer treatment. The research will involve adult cancer survivors who are at least 18 years old and have completed their primary cancer treatments. Participants will either receive a probiotic capsule or a placebo (a capsule with no active ingredients) for 12 weeks, and researchers will analyze stool samples and conduct surveys to understand how these treatments affect their gut health and overall well-being.
To be eligible, participants should have been diagnosed with certain types of cancers, like breast cancer or leukemia, and must be within five years of completing their treatment, ideally in the first year after treatment. They should also be experiencing significant digestive and mental health symptoms. This trial aims to provide valuable insights that could help improve the quality of life for cancer survivors, making recovery a bit easier by addressing some of the long-term side effects of cancer treatment through a simple probiotic capsule.
