Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
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 [Patient Registry]|

- - Age 18 to 75 years, both male and female (including 18 and 75 years old) glioma; - Willing to accept treatment and sign informed consent.
Exclusion Criteria:- Participants with other infection disease or immunodeficiency disease; - other central infectious diseases; - malignant tumor of non-nervous system; - drug abuse; - severe psychiatric disease; - uncontrolled diabetes;
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.
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.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

The disease, disorder, syndrome, illness, or injury that is being studied.
Patient: Adult glioma, pathological diagnosis combined with molecular diagnosis (i.e. IDH- mutant glioma, IDH- mutant glioma with 1p/19q- co-deletion, glioblastoma). The patients were divided into three groups: group A (IDH mutant glioma), group B (IDH mutant with 1p/19q co-deletion oligodendroglioma ) and group C (IDH wild glioblastoma). From the first day after surgery, the ctDNA was extracted with TISF before concurrent chemoradiotherapy as the baseline, and the ctDNA was detected again after concurrent chemoradiotherapy. For the third time, ctDNA was detected in temozolomide intensive chemotherapy. ctDNA was detected for the fourth time when the image showed tumor progression. After the progress, temozolomide combined with bevacizumab was used for chemotherapy. ctDNA was detected 6 weeks after the application of bevacizumab, and ctDNA was re-measured every 6 weeks during the treatment of bevacizumab. At the same time, imaging examination was performed to determine the tumor progress. Check and record adverse events and drug use in detail, and evaluate the compliance of subjects; After TISF tissue extraction, the retained blood samples were sent to simcere Company and Beijing Genetron Health Technology Co. Ltd for ctDNA quantification and detection. To study the differences of gene evolution of different subtypes of glioma under pressure therapy, to clarify the differences of molecular responses of different subtypes of glioma to bevacizumab, and to evaluate the therapeutic effect and safety.
: Gene evolution of glioma in vivo
Group A: gene evolution with relapsed. From the first day after the operation, the ctDNA was extracted from TISF before concurrent chemoradiotherapy as the baseline, and then the ctDNA was detected again after concurrent chemoradiotherapy. For the third time, ctDNA was detected in intensive chemotherapy with temozolomide. The image showed that the tumor progress was detected for the fourth time, and the ctDNA was detected for the fifth time when the tumor recurred. Patients with glioma were routinely treated with temozolomide chemotherapy from the 4th week after operation, for 5 days continuously, once every 4 weeks, with a single dose as follows: Single dose = BSA (body surface area) * 150mg/m2/day BSA(Body Surface Area)=[weight (kg)* height (cm)/3600]2,
: Gene evolution and molecular response under Bevacizumab treatment
After the recurrence, temozolomide combined with bevacizumab was used for chemotherapy, After bevacizumab was applied after six week , ctDNA is tested every six weeks. temozolomide combined with bevacizumab (600mg) in the course of tumor progression once a month.
Drug: - Gene evolution and molecular response under Bevacizumab treatment
Patients with glioma were routinely treated with temozolomide chemotherapy from the 4th week after operation, for 5 days continuously, once every 4 weeks, with a single dose as follows: Single dose = BSA (body surface area) * 150mg/m2/day BSA(Body Surface Area)=[weight (kg)* height (cm)/3600]2, According to the molecular pathological grade (WHO CNS5 grade), it is decided whether to combine radiotherapy (GBM combined with radiotherapy) and temozolomide combined with bevacizumab (600mg) in the course of tumor progression, Recording image changes
