Overall Status
MicroRNAs (miRNA) are molecular biomarkers that post-transcriptionally control target genes. Deregulated miRNA expression has been observed in diverse cancers. In high grade gliomas, known as glioblastomas, the investigators have identified an oncogenic miRNA, miRNA-10b (mir-10b) that is expressed at higher levels in glioblastomas than in normal brain tissue. This study tests the hypothesis that in primary glioma samples mir-10b expression patterns will serve as a prognostic and diagnostic marker. This study will also characterize the phenotypic and genotypic diversity of glioma subclasses. Furthermore, considering the critical function of anti-mir-10b in blocking established glioblastoma growth, the investigators will test in vitro the sensitivity of individual primary tumors to anti-mir-10b treatment. Tumor, blood and cerebrospinal fluid samples will be obtained from patients diagnosed with gliomas over a period of two years. These samples will be examined for mir-10b expression levels. Patient survival, as well as tumor grade and genotypic variations will be correlated to mir-10b expression levels.
Criteria for eligibility
Healthy Volunteers: No
Maximum Age: N/A
Minimum Age: 18 Years
Gender: Both
Criteria: Inclusion/Exclusion Criteria:

- 18 years of age

- Brain tumor(s) to be resected for clinical reasons.

- Histological pathology confirmation that tumor is of glial origin, WHO Grade II, III or IV.

- Adequate tissue available for processing as determined by Pathology.

- Adequate decision making ability to review, discuss and sign a consent form to allow their tumor samples to be used for future human brain tumor biology laboratory research. Determination of capacity to consent is made by one of the co-investigators based on clinical assessment.

- Patients opting for the standard treatment regimen for their disease as well as ongoing clinical trials will be are eligible to participate in this study. Standard care for newly-diagnosed glioblastomas typically consists of surgical resection followed by radiotherapy with concomitant temozolomide, followed by adjuvant temozolomide chemotherapy.
