The Association Between Gut Microbiome Composition Signature and Cancer-related Symptoms in Children With Acute Lymphoblastic Leukemia

Condition(s) studied

Investigational drug(s) / intervention(s)

Questionnaires set: Planned to undergo a complete cycle of induction chemotherapy, with repeated collection of data including disease-related information, cancer-related symptoms, dietary records, and pro-inflammatory cytokine questionnaires. These data will be collected at the following time points: before the initiation of chemotherapy, upon completion of induction chemotherapy or Re-induction I, at 8 weeks post-induction or re-induction therapy, at three months post-induction or re-induction therapy, as well as weekly from the start of chemotherapy until the end of induction chemotherapy or Re-induction I.

fecal sample collecting: Planned to undergo a complete cycle of induction chemotherapy, with repeated collection of fecal sample. These data will be collected at the following time points: before the initiation of chemotherapy, upon completion of induction chemotherapy or Re-induction I, at 8 weeks post-induction or re-induction therapy, at three months post-induction or re-induction therapy, as well as weekly from the start of chemotherapy until the end of induction chemotherapy or Re-induction I.

Study summary

This study is a prospective longitudinal investigation. Data on disease-related information, gut microbiota composition, cancer-related symptoms, dietary intake, and levels of pro-inflammatory cytokines, LPS were collected repeatedly at the following time points: before chemotherapy initiation, at the end of induction chemotherapy or Re-induction I, at 8 weeks after induction or re-induction therapy, at three months after induction or re-induction therapy, as well as weekly between chemotherapy initiation and the end of induction chemotherapy or Re-induction I. The aim is to explore the relationship between gut microbiota composition and cancer-related symptoms.

Eligibility

Primary outcome measure(s)

• Cancer-related symptoms — before the initiation of chemotherapy, upon completion of induction chemotherapy or Re-induction I, at 8 weeks post-induction or re-induction therapy, at three months post-induction or re-induction therapy, as well as weekly from the start of chemotherap
  The cancer-related symptoms will be assessed by Children's Therapy-Related Symptom Checklist (TRSC)
• Cancer-related symptoms — before the initiation of chemotherapy, upon completion of induction chemotherapy or Re-induction I, at 8 weeks post-induction or re-induction therapy, at three months post-induction or re-induction therapy, as well as weekly from the start of chemotherap
  The cancer-related symptoms of sleep will be assessed by Pittsburgh Sleep Quality Index (PSQI)
• Cancer-related symptoms — before the initiation of chemotherapy, upon completion of induction chemotherapy or Re-induction I, at 8 weeks post-induction or re-induction therapy, at three months post-induction or re-induction therapy, as well as weekly from the start of chemotherap
  The cancer-related symptoms of anxiety and depression will be assessed by Pediatric Patient-Reported Outcomes Measurement Information System (PROMIS)
• Gut microbiota signature — before the initiation of chemotherapy, upon completion of induction chemotherapy or Re-induction I, at 8 weeks post-induction or re-induction therapy, at three months post-induction or re-induction therapy, as well as weekly from the start of chemotherap
  Gut microbiota signature will be assessed by fecal sample from children
