Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older who are scheduled to receive high-dose chemotherapy and hematopoietic cell transplantation or CAR-T cell therapy.

Probably not a fit

Patients who do not meet the inclusion criteria or are not undergoing the specified treatments may not benefit from this study.

What this trial studies

This study investigates the changes in the microbiome of cancer patients receiving high-dose chemotherapy and hematopoietic cell transplantation or CAR-T cell therapy. It aims to identify correlations between microbiome alterations and adverse transplant outcomes, such as infections and graft-versus-host disease (GvHD). By analyzing blood, urine, and stool samples, researchers will perform detailed microbiome studies and immune system evaluations to find predictive markers for transplant-related complications. The goal is to potentially modulate the gut microbiota to improve therapeutic outcomes and reduce severe complications.

Why it matters

Potential benefit: If successful, this study could lead to personalized interventions that enhance recovery and reduce complications for cancer patients undergoing intensive treatments.

How similar studies have gone: While there is emerging evidence linking microbiome changes to cancer treatment outcomes, this specific approach is relatively novel and has not been extensively tested in similar studies.
