Gut Microbiota and Glioblastoma Multiforme Prognosis

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Yes
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Observational
Eligible Ages 18 Years - 75 Years
Gender All

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT03631823
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

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.
