Impact of thoracic multidisciplinary tumor boards on the management of patients with cancer: A retrospective study at the American university of Beirut medical center.

Multidisciplinary tumor boards (MDT) provide an opportunity for experts from different specialties and expertise to pool and complement each other's experience and inputs. Several factors impact the MDT discussions, including the meeting's structure, time management, and expert leadership. The process of MDT, their utilization, and efficacy need continuous assessment and improvement. A retrospective study was conducted to review the process of thoracic MDT, their plans of therapy, and changes in diagnosis and treatment plans for patients with cancer at the American University of Beirut Medical Center (AUBMC) over the period of one year. The primary outcome measure was the percentage of patients presented at the thoracic MDT who had a change in their treatment plan after the presentation. A total of 214 cases were scheduled for thoracic MDT during the study period. The majority, 132 (61.7%) did not have a treatment plan before presenting in the MDT. Of the 195 cases presented, only 43 (22.0%) did not have a change in their plan, while 88 (45.2%) of the cases presented had a change in their treatment plan. A total of 64 (32.8%) cases consisted of discussion of the diagnosis during MDT with either confirmation or modification of the patients' diagnosis. Of the 195 cases that were presented, the majority, 170 (87.2%), had their recommended treatment plan implemented after the MDT discussion. There was an association between the stage of cancer at the time of presentation and requesting additional tests (P=0.021), but there was no association between the stage of cancer and change in treatment plan (P=0.177) nor with implementation of recommendation (P=0.217). MDT are used to make upfront management decisions. In addition to considering change in management plans as an indicator of the benefit of MDT, it is suggested that making upfront multidisciplinary plans shall be considered an additional component of indicators of the benefit of MDT.
