Investigating Symptoms & Stool Gut Bacteria between African Americans and Caucasian Americans

Official Title

Associations between Race, Gut Microbiota-Metabolites, and Long-Term Symptom Toxicity in African Americans and Caucasian Americans Colorectal Cancer Survivors

Purpose

The purpose of this study is to learn about the associations of symptoms such as fatigue, depression, and gastrointestinal distress including constipation, abdominal pain, and diarrhea with stool microbiomes and metabolites in patients with colorectal cancer. We will compare the associations of symptoms with microbiomes among colorectal cancer patients and healthy patients. You will be asked to complete several surveys that ask questions about your dietary habits, your health history, your social demographics, and your symptoms. You will also be asked to collect a stool sample with an at-home stool sample collection kit that will be provided to you.
