Evaluate the Effectiveness and Safety of Raman IVD Analyzer in the Molecular Diagnosis of Gliomas During Surgery

Study Purpose

To distinguish various molecular subtypes of gliomas by spectra data obtained from Raman analyzer, including IDH mutant, 1p/19q-codeleted, ATRX deletion, TERT promoter mutation, MGMT promoter methylation, EGFR amplification, H3 K27-altered, TP53 mutant, PTEN deficiency, ki 67, AQP4, VEGF, and so on, comparing with the results of Immunohistochemistry or genetic test on the same brain tissue samples.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
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.	Interventional
Eligible Ages	N/A and Over
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- Patients who plan to undergo brain lesion tissue resection surgery or have preoperative clinical diagnosis of gliomas and plan to undergo biopsy; - Patients with clinical diagnosis of initial solitary gliomas, or initial solitary intracranial masses or initial non occupying lesions that do not exclude gliomas (such as intracranial metastatic lesions, intracranial infectious lesions, intracranial demyelinating lesions, central nervous system lymphoma, etc.), who have not received radiotherapy or chemotherapy in the past based on their medical history; - The patient or their guardian can understand the research purpose, demonstrate sufficient compliance with the trial protocol, consent for immunohistochemistry or genetic test, and sign an informed consent form; - It is possible to obtain tissue samples with a length diameter greater than 0.2cm.

Patients diagnosed with initial solitary glioma should take core or marginal tissue, while patients diagnosed with initial single intracranial mass or initial non mass lesions but maybe with gliomas should be taken core tissue.

Exclusion Criteria:

Investigator judge that it is not suitable for inclusion.

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.	NCT06363162
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.	N/A

Additional Details

1500 samples were included retrospectively with the spectra data obtained from Raman analyzer to establish clinical intelligence model, modifying the analyzer. Based on statistical calculations, 200 glioma samples will be included in the trial in all trial centers prospectively. Compare the results between the Raman analyzer and Immunohistochemistry or genetic test results. And calculate the AUC, the accuracy, sensitivity, the specificity, and other indicators of Raman analyzer. During surgery, core tissue samples were taken from subjects. The test samples size:0.2cm
