Issues in the implementation of cancer staging in Canada.

All sectors of the cancer control community in Canada agree that cancer staging is useful, and that stage should be assigned to every new case. At present, however, staging is not always recorded in the patient's records and treatment patterns and outcomes are rarely reported in terms of stage. This paper discusses what needs to be done to promote the use of staging in Canada. It is concluded that multifaceted programs of interventional continuing education (CE), tailored to meet the needs of the particular institution, offer the best prospect of success but the necessary organizational structure and information systems have to be put into place in advance. Implementation programs should be based on a thorough evaluation of the particular needs of the institution or community, and should be evaluated carefully in a few institutions before an attempt is made to disseminate them more widely. We recommend a phased approach to implementation which will first target institutions that already have the necessary infrastructure, i.e., provincial cancer centres. Demonstration of the feasibility and value of staging in that setting is seen as a means of promoting the adoption of staging in other institutions.
