Background: In current cancer care, multidisciplinary team meetings (MDTMs) aim at uniting care professionals from different disciplines to decide upon the best possible treatment plan for the patients based on the available scientific evidence. In Belgium, the multidisciplinary approach is mandatory and formally regulated since 2003. Current research indicates that MDTMs are not always truly multidisciplinary, ie, with a mix of medical as well as paramedical disciplines, and that the medical profession (physicians and medical specialists) tends to dominate the interaction in MDTMs. To ensure that MDTMs can benefit from their diverse membership to achieve their full potential, significant attention should be devoted to the multidisciplinary character of these meetings. The aim of this study is to explore and describe the multidisciplinary character in MDTMs and how it is actually shaped in practice in different Flemish medical oncology departments.
