Clinical Trial Summary
Study Objective:
Brain tumors are poorly understood. The purpose of this research is to examine whether
factors in lifestyle play a role in brain tumor development. The study will also investigate
the contribution of inherited susceptibility to the risk of brain cancer. By gaining a better
understanding of these influences, the investigators hope to learn how to prevent brain
tumors in future generations, and to develop more effective strategies for treatment.
Study Protocol:
This is a case-control investigation. Persons affected with a brain tumor are compared to
unaffected persons on previous medical history, diet and other factors. Those enrolled in the
study will participate in an interview on general background, diet, medical history and
lifestyle, and will provide a sample of DNA, clippings of your toenails, and a tap water
sample from your home. All procedures are performed in the clinic or through the mail.
'Cases': Cases eligible for the study are persons with a recent diagnosis of a primary brain
tumor (glioma or meningioma), at least 18 years of age.
'Controls': Controls in the study are non-family members of patients, similar in age and of
the same gender. Suitable controls include in-laws, friends, neighbors and co-workers.
Description:
Primary Objective:
The primary objective of this research is to establish a clinic-based case-control study for
examination of potential risk factors for primary adult brain tumors. After assembling a
series of 1,500 cases and 3,000 controls, investigators will test current hypotheses on
ge-netic and environmental risk factors for the occurrence of these tumors.
STUDY DESIGN:
In this case-control study, persons with a recent diagnosis (within 4 months) of a primary
brain tumor will be identified in the neurology/neurosurgery clinics at major treatment
referral centers in the Southeast. Non-blood related relatives (eg. in-laws), friends or
other persons will be recruited as controls. Names and contact information of eligible
controls will be ascertained from patients. A total of 1,500 cases and 3,000 controls will be
enrolled over the course of the 5-year study. All enrolled subjects will complete a one hour
interview on lifestyle, environmental exposures, diet, physical activity, tobacco use and
medical history. They will also be asked to provide a DNA sample, a water sample and a
toenail sample (from each great toe). At the end of data collection, lifestyles and genetic
attributes will be compared in cases and controls to identify any differences that may be
relevant to the causation of disease. Because the study will recruit patients near the time
of disease diagnosis, full enrollment should be possible. In addition, high re-sponse rates
are anticipated among the controls. Thus, with the large numbers of patients available and
high anticipated response rates, the study offers a unique opportunity to successfully
identify environmental and genetic risk factors for this uncommon form of cancer.
