Study Overview
Brief Summary
This research trial studies the gut microbiome in fecal samples from patients with cancer that has spread to other parts of the body who are undergoing chemotherapy or immunotherapy. Studying samples of feces from patients with metastatic cancer in the laboratory may help doctors learn if the make-up of the gut microbiome has a positive or negative influence to a patient's response to chemotherapy or immunotherapy.
Detailed Description
PRIMARY OBJECTIVES:
I. To quantitatively determine the composition of the microflora and their gene and protein expression levels in patients with metastatic colorectal cancer being treated with fluorouracil (5-FU) based chemotherapy, or anti-PD1 immunotherapy.
SECONDARY OBJECTIVES:
I. Compare the changes in species composition and in the metabolic activities (as determined in the primary objective) with response to chemotherapy or immunotherapy.
II. Compare the changes in species composition and in the metabolic activities (as determined in the primary objective) with toxicities and side effects resulting with chemotherapy or immunotherapy.
