Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Little is known about the evolution of genetic and epigenetic changes that occur in the progression of glioma. We inferred the evolution trajectories of matched pairs of primary tumors and progression tumor in situ fluid (TISF) based on deep whole-genome-sequencing data (ctDNA). A monocentric, Gene grouping controlled trial design was used to select patients. and to compare gene evolution of different subtypes of glioma under therapy. To predict the molecular reaction of bevacizumab treatment, clarify the mechanism of drug resistance of bevacizumab treatment.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Gene evolution and molecular response under Bevacizumab treatment

Intervention Type DRUG

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
