Understanding how gut bacteria and immune responses affect cancer spread

Official title: Dissecting the interplay between immunoglobulin G and the gut microbiome in cancer progression and metastasis

Funded at Weill Medical Coll of Cornell Univ · NIH-10758543 · Data updated 2026-11-12

This study is looking at how certain gut bacteria and immune system antibodies might affect cancer spread in older adults, and it hopes to find ways to improve cancer treatment by understanding these connections better, so patients may be asked to share samples or information to help with the research.

Who could benefit from this research

Could help

Ideal candidates for this research include older adults diagnosed with cancer who are undergoing or considering immunotherapy.

Less likely to help

Patients with non-cancerous conditions or those not receiving immunotherapy may not benefit from this research.

What this research studies

This research investigates the relationship between immunoglobulin G (IgG) antibodies and the gut microbiome in the context of cancer progression and metastasis. It aims to uncover how interactions between gut bacteria and the immune system can influence the spread of cancer, particularly in older adults. By identifying specific gut microbes linked to metastatic risk and exploring how these interactions can be leveraged to improve immunotherapy outcomes, the study seeks to enhance our understanding of cancer biology. Patients may be involved in providing samples or data to help elucidate these complex relationships.

Why it matters

Potential benefit: If successful, this research could lead to new strategies for preventing or treating cancer metastasis by targeting gut microbiome interactions.

How similar studies have gone: Previous research has shown promising results in understanding the role of the gut microbiome in cancer treatment, suggesting that this approach could yield valuable insights.
