Identification of Hypermethylated Serum Tumor DNA in High Grade Glioma Patients and Correlation with Magnetic Resonance Imaging Findings


Protocol Version: July 11, 2005


Purpose of Study Eligibility Criteria Treatment Schedule Sample Informed Consent Patient Information

Purpose of Study

To estimate the correlation between changes in the quantity of serum tumor-specific DNA in the serum over time and concurrent changes in brain tumor size as determined by serial MRI or CT scans in patients with malignant glioma.


Eligibility Criteria

Inclusion Criteria

1.                  Patients must be at least 18 years of age. 

2.                  Patients must have histologically confirmed malignant brain tumor by pathology.  A supratentorial grade III or IV, astrocytoma (anaplastic astrocytoma, anaplastic oligodendroglioma, glioblastoma multiforme). 

3.                  Patients must have a Karnofsky performance status ³ 60% (i.e. the patient must be able to care for himself/herself with occasional help from others). 

4.                  Patients must be able to provide written informed consent.

Exclusion Criteria

There are no exclusion criteria for this study. 


Treatment Schedule

Sixty consecutive patients with newly diagnosed or recurrent high-grade astrocytomas who will undergo anti-neoplastic therapy on NABTT protocol will constitute the study population.   Patients participating in this study will sign consent and be registered with the NABTT Central Office.  Pre-Study information including demographic information and performance status will be obtained.  A blood sample for DNA analysis and an MRI will be collected at this time. If the patient is unable to undergo MRI, CT scans will be performed consistently and used for tumor analysis.

Note: patients who do not demonstrate tumor-specific DNA in their plasma will have their total plasma DNA concentration measured at enrollment and followed only for survival. 

Every 2 months (beginning from the time the patient is registered for this study) the following data will be collected:

Ø      KPS

Ø      Blood sample for DNA analysis

Ø      MRI/CT scan

Ø      Treatment Information (what treatment, duration of treatment, etc.)

 The MRI that will be collected every 2 months will be part of standard of care.  Patients will need to return to the clinic every 2 months so that blood can be drawn and a nurse can collect information regarding treatments the patient has received for their brain tumor.  Often, it will be possible to obtain the blood specimen during routine blood draws for tests unrelated to this proposed study.  This will minimize the number venipunctures required. 

Due to the specific nature of the information collected from the patient every 2 months, it will be very important for patients enrolled on this study to have a strong support system.  The patient should appoint an available and able caregiver.  The caregiver will be an additional source of patient information should the patient be unable to remember or communicate the necessary information during the bi-monthly evaluation.

All patients will be followed every 2 months in this manner until death. Patients who are clinically declining may not be able to undergo the required observations.  If a physician feels a patient is clinically unable to comply with required follow up then the patient’s condition and inability to comply with protocol should be documented on the Follow-up/Treatment Form.  Patients in this condition, or who demonstrate no tumor-specific DNA in their blood, will be followed every 2 months only for survival.


Sample Informed Consent

This is a clinical trial (a type of research study).  Clinical trials include only patients who choose to take part.  Please take your time to make your decision.  Discuss it with your friends and family. 

This consent may contain words that you do not understand.  Please ask the study doctor or the study staff to explain any words or information that you do not clearly understand.   

You are being asked to take part in this study because you have been diagnosed with a brain tumor called a glioma.

WHY IS THIS STUDY BEING DONE?

There is special DNA (the chemical that makes up our genes) in each tumor.  This DNA can tell us what special defects are in the genes of your tumor.  Many tumors send their DNA into the blood.  This research study is being done to see if there is tumor DNA in your blood.  If there is, we want to know if it tells us anything about your tumor and how it behaves. Tumor DNA in the blood can be collected with a routine blood draw and then tested. We know that we can detect the special defects in the genes of your tumor with a very sensitive test called PCR.  We know that these defects may change within one person’s tumor over time.  We don’t know if the changes in these defects will predict changes in the type of tumor or its size.  In this research study we would like to look at the gene defects found in the DNA in your blood and see how they change over time.  We would like to compare the changes in your blood to the changes seen in your tumor by using a brain scan.  The information we collect from this research study will help us better understand brain tumors and how we can better treat them.

HOW MANY PEOPLE WILL TAKE PART IN THIS STUDY? 

About 60 people will take part in the study.

WHAT IS INVOLVED IN THE STUDY?

Before joining this study your medical history will be reviewed and blood will be drawn for a DNA analysis.  An MRI of your brain will also be obtained.  These evaluations will be repeated every other month.  You will need to return to this institution every other month for these evaluations.  The MRI that is obtained is part of your standard care.  There is nothing experimental about the MRI.  The blood collected for this study is for research purposes only and would not be collected if you were not participating in this study.  

You can also stop participating at any time.  However, if you decide to stop participating in the study, we encourage you to talk to the researcher and your regular doctor first.

 WHAT ARE THE POTENTIAL RISKS?

 Drawing blood from your arm may cause pain, bruising, lightheadedness, and, on rare occasions, infection at the site of the needle puncture.

 You will be told of any new information that may be discovered while you are participating in this study that might change your decision to be in this study.

USING YOUR DNA FOR FUTURE RESEARCH

 The DNA in your blood being collected for this study will be analyzed.  We would like to keep some of the DNA that is left over for future research.  If you agree, this DNA will be kept and may be used in research to learn more about cancer. 

 The research that is done with your DNA is not designed to specifically help you.  It might help people who have cancer in the future.

 Reports about research done with your DNA will not be given to you or your doctor.  These reports will not be put in your health record.  The research will not have an effect on your care.

 Things to think about:  The choice to let us keep your DNA for future research is up to you.  No matter what you decide to do, it will not affect your care.  If you decide now that your DNA can be kept for research, you can change your mind at any time.  Just contact us and let us know that you do not want us to use your DNA.  Your DNA will no longer be used for research.  In the future, people who do research may need to know more about your health.  While the “researcher” may give them reports about your health, it will not give them your name, address, phone number or any other personal information that will let the researchers know who you are. Your DNA will be used only for research and will not be sold.  The research done with your DNA may help to develop new products in the future. 

Benefits:  The benefits of research using DNA include learning more about how to treat cancer. 

Risks:  The greatest risk to you is the release of information from your health records.  We will do our best to make sure your personal information will be kept private.  The chance that this information will be given to someone else is very small. 

Making your choice: Please read each sentence below and think about your choice.  After reading each sentence, circle “Yes” or “No”.  If you have any questions, please talk to your doctor or nurse, or call our research review board at IRB’s phone number.

No matter what you decided to do, it will not affect your care.
