BioBank or Biorepository What is a BioBank? a resource that collects, stores, processes and distributes human specimens such as tissue, body fluids, and blood to scientists for a various research projects. UHN BioBank Established in 2001 Currently, stores samples from over 20,000 patients, equaling over 60,000 high quality biospecimens. Current computer system: Oracle back Access front end Storage location Patient demographics and consent Pathology diagnosis (text data fields)

Princess Margaret Hospital Cancer Registry Princess Margaret Hospital 0pened in 1958 in Toronto, Ontario Hospital Cancer Registry was in operation from the beginning In 1998 became part of the University Health Network along with 2 acute care facilities that perform primary cancer surgery Over 12,000 new cancer cases per year. Collect standard registry information according to NAACCR standards Demographics Disease Stage Treatment Follow-Up

POP-Cure Colon Cancer Study The goal of this study is to identify and validate new molecular biomarkers and potential therapeutic targets through complementary genomic and functional genomic approaches coupled with molecular pathology and a large retrospective and prospective clinical biobank. Stage II and III colon adenocarcinoma

POP-Cure-Project Flow Cancer Registry Identified Colon Cases for 2001 onwards to match time period of the bank Biobank pulled slides for the cases.
