Correlation Between SPECT/CT and IDH Mutation in Brain Glioma

Study Purpose

Major advances in cancer genetics over the past decade have revealed that the genes encoding IDHs are frequently mutated in a variety of human malignancies, including gliomas.Pentavalent 99mTc dimercaptosuccinic acid (99mTc (V) DMSA), is a nonspecific tumor targeting SPECT radiotracer, that has been used for imaging of various tumors including lung and breast carcinoma. However, to date, scarce reports discussed the utility of DMSA-V in patients with glioma.SPECT has the advantages of being widely available and not expensive. Multiple SPECT tracers have been explored. Of them Thallium-201 and 99 mTc-MIBI are, possibly, the most extensively discussed.

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.	Observational
Eligible Ages	N/A and Over
Gender	All

- patients conscious to provide informed consent.

Exclusion Criteria:

- Pregnant women.

- severely ill patients and those with disturbed conscious level, - patients who were judged that they cannot lie down comfortably without movement for at least 20 min.

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.	NCT05595863
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.

Additional Details

Every year, nearly100,000 people worldwide are diagnosed as having brain gliomas. Although it comprises <1% of all newly diagnosed cancers, brain glioma is associated with substantial mortality and morbidity. Gliomas are intrinsic brain tumors that originate from neuroglial progenitor cells. Conventional therapies, including surgery, chemotherapy, and radiotherapy, have achieved limited improvements in the prognosis of glioma patients. Radiation therapy to the brain may lead to postradiation injury which typically occurs within the first 3 to 12 months after radiotherapy but it was reported up to several years and even decades later. The clinical picture of radiation necrosis (RN) is variable and may include seizures, headache, personality changes, and neurologic deficits. These symptoms mimic tumor recurrence and differentiation between the two entities clinically or even by conventional radiological modalities is difficult but is necessary because the two conditions have different treatment modalities and prognosis. SPECT has the advantages of being widely available and not expensive. Multiple SPECT tracers have been explored. Of them Thallium-201 and 99 mTc-MIBI are, possibly, the most extensively discussed. The main disadvantage of 201Tl is the lower spatial resolution, relatively large radiation dose, and the reported high false positive results. Normal uptake of MIBI in the choroid plexus may be confounding for assessing tumors around the ventricles. Pentavalent 99mTc dimercaptosuccinic acid (99mTc (V) DMSA), is a nonspecific tumor targeting SPECT radiotracer, that has been used for imaging of various tumors including lung and breast carcinoma. However, to date, scarce reports discussed the utility of DMSA-V in patients with glioma. Isocitrate dehydrogenase (IDH) enzymes, of which there are three isoforms, are essential enzymes that participate in several major metabolic processes, such as the Krebs cycle, glutamine metabolism, lipogenesis and redox regulation. Major advances in cancer genetics over the past decade have revealed that the genes encoding IDHs are frequently mutated in a variety of human malignancies, including gliomas, acute myeloid leukaemia, cholangiocarcinoma, chondrosarcoma and thyroid carcinoma.
