Gut Microbiota and Glioblastoma Multiforme Prognosis


Glioma is the most common primary cancer of the central nervous system, and around 50% of patients present with the most aggressive form of the disease, glioblastoma. Conventional therapies, including surgery, radiotherapy, and pharmacotherapy (typically chemotherapy with temozolomide), have not resulted in major improvements in the survival outcomes with only a median survival of around 15 months.The main reason may be related to the highly immunosuppressive tumor microenvironment. In recent years, the microbiome has emerged as a key regulator of not only systemic immune regulation but brain circuitry, neuro-physiology and microglia development. We hypothesized that there is a link between the gut microbiota and the GBM development and evolution through the immune regulation cells (microglia and tumor related macrophagocyte) in the blood circulation to impact the prognosis( PFS and MST) of GBM patients.

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Prospective
  • Study Primary Completion Date: August 10, 2019

Detailed Description

We divide the paticipants into three groups. (total number = 200 subjects) 1. Radio/Chemotherapy group – 80 subjects 2. Radio/ without chemotherapy group – 70 subjects 3. Healthy volunteer group – 50 subjects After the collection of stools before operation and 3 months after the operaton, we will analyze the composition and distribution of gut microbiota, and compare the results of three experiment groups.Then we will followe up the patients and analyze the correlation between gut microbiota and prognosis of GBM.


  • Other: Chemotherapy with temozolomide or no chemotherapy
    • This study is just an observational study.

Arms, Groups and Cohorts

  • Radio/Chemotherapy group
    • The participants in this group receive the concurren radio/chemotrherapy
  • Radio/ without chemotherapy group
    • The participants in this group receive the radiotherapy but without chemotrherapy
  • Healthy volunteer group
    • The volunteers for control group

Clinical Trial Outcome Measures

Primary Measures

  • Pre-operative gut microbiota in molecular subtype glioblastoma mutiforme multiform
    • Time Frame: 12 months
    • To analysis the distribution and components of gut microbiota before operation
  • The perturbation of gut microbiota by temozolomide chemotherapy
    • Time Frame: 15 months
    • To investigate the change of components of gut microbiota induced by chemotherapy
  • Link the gut microbiota and prognosis of GBM
    • Time Frame: 20 months
    • To explore the correlation between the gut micriobiota and the prognosis (PFS and MST) by bioinformatic big data process.
