Sponsored by The University of Texas Health Science Center at San Antonio · Observational
This is a simple tissue collection study with no therapeutic intent. Colon tissues will be taken from standard of care procedures. Tissues will be tested for their functions, expression of immune co-signaling molecules and reactions to transduction with recombinant Listeria vectors to assess effects on expression of B7-H1 and cytokines.
1,432 studies on the registry are indexed under Colonic Neoplasms; 357 are open to participants now.
