Genotoxicity Assessment for Patients Undergoing Radiation Treatment
The purpose of the research study is to evaluate an automated, laser-based technique for measuring DNA damage caused by radiation during cancer treatment in immature red blood cells.
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||Genotoxicity Assessment for Patients Receiving Large Field Irradiation|
- Measure the Change in MN-RET in the blood [ Time Frame: Baseline and 1 day ] [ Designated as safety issue: No ]
|Study Start Date:||April 2006|
|Estimated Study Completion Date:||October 2018|
|Estimated Primary Completion Date:||October 2015 (Final data collection date for primary outcome measure)|
Correlative studies: analysis of RT effect on genotoxicity by assessing cytogenetic changes (dicentrics), micronucleated lymphocytes (MN-lymph), and micronucleated reticulocytes (MN-RET) using peripheral blood of patients receiving radiation.
i) document the kinetics by which radiation-induced MN-RET enter the peripheral blood stream.
ii) benchmark the MN-RET endpoint against current gold-standard biodosimetry endpoints—dicentrics and MN-lymphocytes.
iii) measure inter-individual variation in baseline and radiation-induced MN-RET frequencies.
iv) in collaboration with several FCM-equipped laboratories, evaluate the transferability of the human MN-RET scoring assay.
