Associations of Fatigue and Chemotherapy-Induced Nausea With Changes in Gut Microbiome Composition Profiles
Mayo Clinic
Summary
This pilot study seeks to understand how changes in the bacteria composition (microbiome) of the gut may be associated with the occurrence of fatigue and chemotherapy-induced nausea (CIN) in women undergoing chemotherapy for early stage breast cancer. Patients undergoing chemotherapy may experience fatigue or nausea as a result of their treatment. Known risk factors for fatigue and CIN do not explain the differences in fatigue and CIN occurrence between patients, but changes in the functions of the gut microbiome may be related to the occurrence of fatigue and CIN. This study collects stool samples from breast cancer patients before and after chemotherapy to evaluate how changes in the microbiome may be associated with fatigue and CIN.
Description
PRIMARY OBJECTIVES: I. Evaluate the feasibility of patient recruitment and retention, as well as specimen collection. II. Estimate the effect size for changes in gut microbiome composition profiles and metabolites in stool as well as blood from time of first stool sample collection prior to chemotherapy (T1) to time of second stool sample collection after chemotherapy (T2) that are associated with the occurrence of fatigue and CIN. III. Evaluate associations between patient reported demographic and clinical characteristics, comorbidities at T1, and changes in gastrointestinal and neuropsych…
