Read the detailed description

Brain diseases are very difficult diseases to treat, and when developing related medical cures for saving lives, however, it is difficult to obtain examining samples, especially like normal brain tissue since it is necessary to preserve the brain tissue of patients to ensure its functionality. Among the numerous brain diseases, there are many diseases that combine surgery, chemotherapy, and immunotherapy in treatment. For example, for brain tumors, surgery is the most important treatment that can effectively prolong the survival time of patients. Numerous neurological functions, tumors generated in such important organs, require careful judgment of resection strategy in surgical treatment. In addition to achieving complete tumor resection, subsequent chemotherapy and immunotherapy are also important factors to improve prognosis. Traditionally, the neurosurgeon's experience and various preoperative examinations are used to judge the type and distribution of the disease, which may lead to inconsistent results due to different personal experiences. The current methods that can be used clinically to help improve the integrity of resection (such as intraoperative fluorochrome and intraoperative magnetic resonance imaging) are relatively indirect methods of judgment, but it is hard to directly know the detailed information of the disease before surgery, and the assessment results of formalin-fixed paraffin-embedded (FFPE) section through the standard operation of pathological procedures are used to formulate drug treatment strategies, which may greatly affect the prognosis of patients. According to the current intraoperative cryopathology, there are many brain tumors that cannot be classified easily by it. When searching the literature, there are also few related studies that try to solve this problem, but in addition to the insufficient sample size, it is also impossible to acquire appropriate conclusions due to the limited number of samples. Therefore, through this study, we want to implement optical microscopy and electrophysiological analysis system to capture images and electrophysiological signals of some remaining brain diseased tissues after surgical resection, and compare the acquired datas with the results obtained from human brain organoid tissues. Eventually, construct a large database of brain tissue can also verify whether human brain organoids can completely compare with real human brain samples can truly improve the medical operation.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Electrophysiological systemDevice

    Electrophysiological system is used for examining voltage variation in biological samples. And multiphoton microscopy is a common type of nonlinear optical microscope.

  • Multiphoton microscopeDevice

    Multiphoton microscope acquires high-resolution image based on nonlinear optics and can be used for detect biological specimens.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Acquire neuronal structual (image frame) results of different brain regions

    By interpreting the microscopic images of different brain regions' tissues , an attempt is made to understand the structure of brain disease tissues (via cell morphology, microvessels, etc).

    Measured: 3 years

  2. Acquire electrophysiological readout (voltage amplitude, mV) datas of different brain regions

    By interpreting the neuron electric reactive datas, an attempt is made to know the neuronal activity (via detecting voltage amplitude change) between multiple neurons.

    Measured: 3 years

Secondary outcomes (1)
  1. To conduct imaging for multiple types of human brain tissues and construct the neuron image database

    Accumulating the microscopic images and neuron electrosiological signals, the image database of normal and diseased neuron reaction can be constructed.

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

A study testing Electrophysiological system and Multiphoton microscope in people with Brain Diseases and Brain Tumor, run by National Taiwan University Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 21 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Kuo-Chuan Wang (+886-23123456 ext. 263155, wang081466@yahoo.com.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Acquire neuronal structual (image frame) results of different brain regions (time frame: 3 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Aug 2024.
