Summary
Brief summary (as posted)
This clinical trial evaluates the effects a probiotic intervention has on the gut and vaginal microbiome in patients undergoing chemotherapy for ovarian cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) or that has come back after a period of improvement (recurrent). Gut health is also known as the gut microbiome. The microbiome includes all of the bacteria and organisms naturally found in the digestive tract. Probiotics are dietary supplements containing live microorganisms that may help keep the gastrointestinal tract healthy. A probiotic intervention during platinum chemotherapy in ovarian cancer patients may impact the gut and vaginal microbiota, quality of life, symptoms, and oncologic outcomes.
