The Value of Multidisciplinary Team Meetings for Patients with Gastrointestinal Malignancies: A Systematic Review

INTRODUCTION: The incidence of gastrointestinal (GI) cancer is rising and most patients with GI malignancies are discussed by a multidisciplinary team (MDT). We performed a systematic review to assess whether MDTs for patients with GI malignancies can correctly change diagnosis, tumor stage and subsequent treatment plan, and whether the treatment plan was implemented. METHODS: We performed a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We conducted a search of the PubMed, MEDLINE and EMBASE electronic databases, and included studies relating to adults with a GI malignancy discussed by an MDT prior to the start of treatment which described a change of initial diagnosis, stage or treatment plan. Two researchers independently evaluated all retrieved titles and abstracts from the abovementioned databases. RESULTS: Overall, 16 studies were included; the study quality was rated as fair. Four studies reported that MDTs changed the diagnoses formulated by individual physicians in 18.4-26.9% of evaluated cases; two studies reported that MDTs formulated an accurate diagnosis in 89 and 93.5% of evaluated cases, respectively; nine studies described that the treatment plan was altered in 23.0-41.7% of evaluated cases; and four studies found that MDT decisions were implemented in 90-100% of evaluated cases. The reasons for altering a treatment plan included the patient's wishes, and comorbidities. CONCLUSIONS: MDT meetings for patients with a GI malignancy are responsible for changes in diagnoses and management in a significant number of patients. Treatment plans formulated by MDTs are implemented in 90-100% of discussed patients. All patients with a GI malignancy should be discussed by an MDT.
