What this trial studies

This observational study investigates the relationship between the gut microbiome and the effectiveness of cancer therapies in patients with hematopoietic and lymphoid cell neoplasms or malignant solid neoplasms. By collecting blood and stool samples and reviewing medical records, researchers aim to correlate specific gut microbiome profiles with clinical responses and side effects of cancer treatments and stem cell transplants. The findings may lead to improved cancer treatment strategies tailored to individual microbiome compositions.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18-99 who have been diagnosed with cancer and are undergoing or scheduled to start cancer therapy or a stem cell transplant.

Not a fit: Patients who are unable to provide informed consent or are considered vulnerable adults may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the effectiveness of cancer therapies by personalizing treatment based on gut microbiome profiles.

How similar studies have performed: Other studies have shown promising results in understanding the role of the microbiome in cancer treatment, suggesting that this approach is both relevant and potentially impactful.
