RATIONALE: Studying samples of blood and tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment.
PURPOSE: This research study is looking at blood and cheek cell samples from patients with glioma.
- Determine factors related to glioma survival in patients from two population-based case series collected in the San Francisco Bay Area between August 1991 and April 1994 (series 1) and May 1997 and August 1999 (series 2).
- Determine vital status for 879 patients in the two San Francisco Bay Area population-based series through July 2004.
- Determine survival as a function of established, potential, and yet unstudied prognostic indicators.
- Gather data to validate results from this study with information from adult glioma patients enrolled prospectively at the UCSF-Neuro-Oncology clinic and through series 3 of the San Francisco Bay Area Adult Glioma Study; incorporate results from this study and other components of the SPORE into ongoing clinical investigations at the Brain Tumor Research Center and Neuro-Oncology Service at UCSF.
- Using funding from the organization Accelerate Brain Cancer Cure (ABC2), genotype several thousand single nucleotide polymorphisms (SNPs) from some study participants; assess these SNPs for potential relationship to glioma survival.
OUTLINE: Medical records of patients registered to the California Cancer Registry or the Northern California Cancer Center SEER are reviewed for mortality and treatment information related to the brain tumor. Blood and buccal specimens are collected from patients with newly diagnosed disease who are being seen at the UCSF Neuro-Oncology Service. The specimens are used for polymporphism and tumor marker studies and other pertinent data. Tumor specimens and treatment information related to the brain tumor are also collected from the SPORE Tissue Core.
Additional tumor makers are studied, including: chromosome 1p/19q, 7q studies; DNA repair and oxidative metabolism polymorphisms; and up to 2 tumor markers and 2 constitutive genotyping studies.

α-defensin is a biomarker which has been described as having a high degree of accuracy in the diagnosis of periprosthetic joint infection (PJI). Current meta-analyses are based on the α-defensin lab...
To determine whether prostate-specific antigen (PSA) could serve as a biomarker for breast cancer.
The association between aryl hydrocarbon receptor gene (AhR) polymorphism and male infertility risk remains conflicting. We conducted a meta-analysis to examine the AhR Arg554Lys polymorphism in relat...
Formal programs for assessing drug prescription against some standard. Drug utilization review may consider clinical appropriateness, cost effectiveness, and, in some cases, outcomes. Review is usually retrospective, but some analysis may be done before drugs are dispensed (as in computer systems which advise physicians when prescriptions are entered). Drug utilization review is mandated for Medicaid programs beginning in 1993.
The detection of RESTRICTION FRAGMENT LENGTH POLYMORPHISMS by selective PCR amplification of restriction fragments derived from genomic DNA followed by electrophoretic analysis of the amplified restriction fragments.
A method of chemical analysis based on the detection of characteristic radionuclides following a nuclear bombardment. It is also known as radioactivity analysis. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
RESTRICTION FRAGMENT LENGTH POLYMORPHISM analysis of rRNA genes that is used for differentiating between species or strains.
Meta-analysis of randomized trials in which estimates of comparative treatment effects are visualized and interpreted from a network of interventions that may or may not have been evaluated directly against each other. Common considerations in network meta-analysis include conceptual and statistical heterogeneity and incoherence.

Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
