Detailed Description

Cancer-related fatigue is experienced by nearly all patients during treatment, and cancer-related cognitive impairment (CRCI), which is a decrease in neurocognitive functioning that can be caused by cancer or its treatment, is present in up to ¾ of patients during treatment. Fatigue and CRCI have both been linked to the composition of the gut microbiome in cancer patients. CRCI is often reported as one of the most debilitating and life-altering aspects of cancer and treatment. Although CRCI is widely reported in patients with a variety of cancers and undergoing a variety of treatments, it is not clear if the mechanisms leading to symptoms are the same throughout. Using identical methods to monitor CRCI symptoms and microbial dysbiosis in a cross-section of various cancers, cancer stages, and treatments, can help to identify commonalities associated with symptoms. Specific Aims Specific Aim 1: Characterize the microbiome of cancer patients and compare to healthy control subjects from previous studies. Specific Aim 2: Assess fatigue in cancer patients and determine associations with composition of the gut microbiome.


Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health). The listing of studies provided is not certain to be all studies for which you might be eligible. Furthermore, study eligibility requirements can be difficult to understand and may change over time, so it is wise to speak with your medical care provider and individual research study teams when making decisions related to participation.
