Primary Outcome Measures:
  • Polymorphisms in selected genes in relation to specific mutations and types of mutation in the c-kit gene [ Designated as safety issue: No ]

Estimated Enrollment: 374
Study Start Date: December 2008
Estimated Primary Completion Date: June 2009 (Final data collection date for primary outcome measure)
Detailed Description:



  • To examine polymorphisms in selected genes involved in the detoxifying/metabolizing and DNA repair pathways in relation to specific mutations and types of mutation in the c-kit gene in tumor tissue from patients with gastrointestinal tumors (GIST) undergoing treatment on clinical trial ACOSOG-Z9001.


  • To examine approximately 758 polymorphisms among candidate genes involved in detoxification/metabolism, cell cycle control, and DNA damage/repair in relation to specific mutations and types of mutation in the c-kit gene in tumor tissue from GIST patients for hypothesis generation. (exploratory)
  • To conduct an exploratory analysis of the polymorphism distribution in these patients. (exploratory)
  • To examine the association between the above polymorphisms and major toxicity (Grade 3/4) of adjuvant imatinib mesylate. (exploratory)

OUTLINE: Tumor samples are used for polymorphism and mutation analysis.
