RATIONALE: Studying levels of tumor DNA in the samples of blood from patients with cancer may help doctors find out whether the cancer has grown and how much.

PURPOSE: This laboratory study is comparing levels of tumor DNA with MRI and CT scan findings to measure cancer growth in patients with grade III or grade IV malignant glioma.

Condition Intervention
High Grade Glioma Procedure: DNA methylation analysis Procedure: polymerase chain reaction Procedure: computed tomography Procedure: magnetic resonance imaging

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment

Primary Outcome Measures:
  • Total plasma glioma-specific DNA concentration [ Time Frame: every 2 months until death ]
  • Tumor size [ Time Frame: every 2 months until death ]

Enrollment: 42
Study Start Date: April 2005
Primary Completion Date: August 2009 (Final data collection date for primary outcome measure)
Intervention Details:
    Procedure: DNA methylation analysis
    Other Name: blood collection
    Procedure: polymerase chain reaction
    Other Name: blood collection
    Procedure: computed tomography
    Other Name: CT scan
    Procedure: magnetic resonance imaging
    Other Name: MRI scan
Detailed Description:


  • Correlate changes in the level of serum tumor-specific DNA over time with changes in brain tumor size as measured by serial MRI or CT scans in patients with grade III-IV malignant gliomas.

OUTLINE: This is a multicenter study.

Blood samples are collected from patients at baseline and every 2 months thereafter. Tumor and nontumor plasma is extracted. Plasma samples are analyzed by polymerase chain reaction (PCR) to assess the p16_ink4a, p73, and O ^6-MGMT gene promoter methylation profile. Quantitative realtime PCR is performed on samples with tumor-specific DNA to determine the plasma concentrations of each methylated tumor-specific gene and the total plasma tumor-specific DNA concentration. Patients also undergo MRI or CT scans every 2 months.

PROJECTED ACCRUAL: A total of 60 patients will be accrued for this study.
