The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.

University of Wisconsin, Madison
  Purpose
The purpose of this study is to compare the baseline incidence of variant alleles in the ATM and/or other DNA repair genes present in the Native American population versus the non-Native American population. It is thought that a higher baseline incidence of the variant alleles in the ATM gene may correlate to higher rates and higher grades of radiation toxicities noted in the Native American population.

Condition
Radiotherapy

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: ATM Variants in Radiotherapy

Further study details as provided by University of Wisconsin, Madison:

Primary Outcome Measures:
  • to determine baseline incidence of variant alleles in ATM [ Time Frame: one blood draw ]
    to determine the baseline incidence of variant alleles in ATM resent in the population of Native americans with cancer who are undergoing radiation therapy to a similar group of non-native americans who have undergone or are undergoing raditohterapy


Secondary Outcome Measures:
  • to compare the baseline incidence of variant alleles in ATM [ Time Frame: one blood draw ]
    to compare the baseline incidence of variant alleles in ATM resent in the population of Native americans with cancer who are undergoing radiation therapy to a similar group of non-native americans who have undergone or are undergoing raditohterapy


Biospecimen Retention:   Samples With DNA
direct sequence analysis of all exons and intron-exon junctions of the ATM gene. DNA will be isolated from lympocytes using the PAX blood DNA system.

Enrollment: 60
Study Start Date: December 2007
Study Completion Date: January 2013
Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
