Symptom patterns and gut bacteria in childhood cancer survivors

A Multicenter Study on the Heterogeneity of Symptom Clusters and the Underlying Mechanisms of Gut Microbiota and Metabolites Among Childhood Cancer Survivors

Observational The Children's Hospital of Zhejiang University School of Medicine · NCT07450872

This project will test whether groups of ongoing symptoms in childhood cancer survivors are linked to differences in gut bacteria and their metabolites.

What this trial studies

This observational study enrolls childhood cancer survivors aged 8–18 who are in rehabilitation/maintenance or finished treatment at least six months earlier. Participants complete questionnaires at multiple time points to track symptom patterns such as fatigue, pain, sleep disturbance, and mood, and provide stool samples for gut microbiota and metabolite profiling. Researchers will perform longitudinal symptom-cluster analysis alongside microbiome and metabolome sequencing to identify associations between symptom clusters and microbial/metabolic features. The goal is to clarify biological mechanisms behind persistent symptom groups and identify microbial signals that could inform future supportive care strategies.

Who should consider this trial

Good fit: Ideal participants are childhood cancer survivors aged 8–18 who can complete questionnaires independently, are in rehabilitation/maintenance or at least six months post-treatment, and consent to provide stool samples.

Not a fit: Children with severe treatment-related organ or neurological impairments, those unable to complete questionnaires independently, or those starting new major cancer therapy during the study are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, this work could point to microbiome-based or tailored supportive strategies to reduce symptom burden and improve quality of life for childhood cancer survivors.

How similar studies have performed: Prior human and animal studies have linked gut microbiota to fatigue, mood, and gastrointestinal symptoms, but applying microbiome and metabolite profiling specifically to symptom clusters in childhood cancer survivors is relatively novel.
