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.

Who should consider this trial

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.

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

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 performed: 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.
