Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 18 and older who have been diagnosed with gastrointestinal cancers and are scheduled for treatment at the National Institutes of Health.

Probably not a fit

Patients who do not have a diagnosis of gastrointestinal cancer or are under 18 years of age may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to gather blood and tumor tissue samples from individuals diagnosed with gastrointestinal cancers, such as throat, stomach, gallbladder, liver, pancreatic, or colon cancer. The objective is to analyze the immune system's response to these cancers and understand the role of gut microbiota in cancer progression. Participants will undergo a screening process and provide baseline samples during one to four visits to the National Institutes of Health Clinical Center. The findings may help inform future immunotherapy approaches and improve treatment strategies.

Why it matters

Potential benefit: If successful, this study could enhance our understanding of immune responses in gastrointestinal cancers and lead to more effective treatment options.

How similar studies have gone: Other studies have shown promise in understanding immune responses in cancer, suggesting that this approach could yield valuable insights.
