Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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<length diameter ≤ 2cm. The sample testing result is based on the Raman test points. Then take the same tissue sample for Immunohistochemistry or genetic test.

Statistical description of all data, including baseline data, all efficacy indicators, and all safety data. The measurement data give the mean, standard deviation, minimum, maximum, median,25 quantile and 75 quantile; Provide frequency and composition ratio for counting data. The baseline data was analyzed using the Full Analysis Set (FAS); The effectiveness analysis adopts FAS and PPS; The security analysis uses the Security Dataset (SS).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
