Collecting blood and tissue samples from patients with gastrointestinal cancer

Acquisition of Data, Blood, and Tumor Tissue Samples From Patients With Gastrointestinal Cancer

Observational National Institutes of Health Clinical Center (CC) · NCT01313442

This study is collecting blood and tissue samples from people with gastrointestinal cancers to see how their immune system and gut bacteria affect the disease and to help improve future treatments.

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.

Who should consider this trial

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.

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.

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