About this study

The purpose of the study is to:

  • Map and compare the neoplasia-associated epigenetic field in IBD-CRN, sporadic CRN and controls.  
  • Measure sensitivity of DNA methylation for the detection of synchronous IBD-CRN as a complement or alternative to histologic diagnosis of dysplasia on random biopsies. 
  • Measure the density and types of lymphocytes infiltrating IBD-CRN tumors, sporadic tumors and the epigenetic field.
