A Longitudinal Study of Colorectal Cancer Patients With Metastatic Disease in Middle-Norway

The available evidence-based knowledge of patient management is translated into regularly updated clinical guidelines for diagnosis, staging and treatment. The guidelines represent the basis for oncology care in Norway, and health care providers are expected to follow these guidelines. Current guidelines are derived from studies where patients are highly selected and not representative for the whole cohort of patients with metastatic disease. One can speculate if the results of trials conducted in regional centers can be generalized to whole populations in a region. In this respect it will be valuable to study advanced colorectal cancer in the whole population of Middle-Norway, with both one regional center and all other hospitals in the area. More knowledge is needed for the optimal selection of treatment for individual patients. In relation to symptom relief, physical and psychological functioning and overall quality of life, there is clearly a lack of high quality research. A longitudinal follow-up of a large number of metastatic colorectal cancer patients with regular assessments has not been previously launched. The existing infrastructure in Norway makes the study feasible and will provide high internal and external validity related to clinical outcomes. The study will constitute a unique platform for comprehensive research aimed at this patient group. It also provides a concept that can be transferred to other major diseases, and it can be extended to other health regions of Norway.
