Summary
Brief summary (as posted)
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.

Arms and outcomes
Arms (1)
- label
- Ancillary-Correlative (gut microbiome analysis)
- description
- Patients undergo collection of fecal specimens at baseline, prior to start of each course of chemotherapy or immunotherapy, at the end of weeks 2, 4, 6, and 8, at the end of course 3 and courses thereafter of chemotherapy or immunotherapy, and at the time of disease progression or going off-treatment. Fecal specimens are analyzed via 16S ribosomal RNA gene sequencing, meta-transcriptomics analysis, and meta-proteomics analysis.

- measure
- Best tumor response, defined as a complete response or a clear decrease in tumor burden
- timeFrame
- Up to 2 years
- description
