Canadian Cancer Trials Group Bulletins

Correlative Science / Tumour Bank

The NCIC Clinical Trials Group (Canadian Cancer Trials Group) established the Tumour Tissue Data Repository (TTDR) in 1997 to support Correlative Science with the assistance of Rhone Poulenc Rorer (now Sanofi-Aventis). The Canadian Cancer Trials GroupTTDR contains unique disease specific collections which are linked to an associated clinical dataset. This represents a "real" tumour bank in that tissue is collected from institutions across Canada and the world, catalogued and housed centrally in the Department of Pathology and Molecular Medicine at Queen's University.

Our Mission

To establish a collection of specimens stored in house and linked with clinical trials dataset. Access to this tissue permits the assessment of prognostic factors in determining the outcome of disease, the assessment of predictive factors to various chemotherapeutic agents and treatment regimens, and to facilitate the understanding of the basic biological and genetic mechanisms of cancer.


The Canadian Cancer Trials Group TTDR has taken part in collection of tissue for over 120 clinical trials. The central coordinating office for the Bank is located in Kingston, Ontario. Participating centres include cancer care organizations, academic health science centres, community hospitals, and smaller individual practices. These centres were initially in Canada but more recently samples have been collected worldwide.
