The purpose of this study is to develop fecal tests that will determine the extent of radiation exposure in patients undergoing radiation treatment for cancer. This project will determine whether fecal biomarkers can be used to diagnose exposure to radiation.

Further study details as provided by Medical College of Wisconsin:

Primary Outcome Measures:
  • To describe changes in gene expression associated with exposure to radiation [ Time Frame: prior to TBI treatment (baseline) and up to 2 weeks following the last dose of TBI ] [ Designated as safety issue: No ]
    Changes in gene expression will be measured as abundance of RNA levels relative to the weight of feces

Biospecimen Retention:   Samples With DNA


Estimated Enrollment: 20
Study Start Date: November 2010
Estimated Primary Completion Date: November 2013 (Final data collection date for primary outcome measure)
TBI prior to stem cell transplantation

Detailed Description:

Patients undergoing TBI as part of a hematopoietic stem cell transplant (HSCT) will have feces collected for use in the validation and refinement of new methods for rapid radiation biodosimetry. The stool samples will be collected before, and at defined times after TBI. Stool sampling will occur in the same manner that it does during routine patient care during HSCT.


Ages Eligible for Study:   2 Years to 21 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Patients undergoing Total Body Irradiation (TBI) preceding hematopoietic stem cell transplantation.


Inclusion Criteria:

  • All races are eligible
  • 2 years to 21 years old
  • Must be undergoing hematopoietic stem cell transplantation (either autologous or allogeneic) in conjunction with a conditioning regimen that includes total-body irradiation (TBI) (single or multiple fraction).
