The role of the multidisciplinary tumor board after endoscopic resection of malignant tumors: is it worth it?

OBJECTIVES

The value of multidisciplinary tumor boards (MTBs) in the treatment of gastrointestinal cancer patients is well known. Most of the current evidence focuses on advanced cancer cases, whereas little is known about the effect of MTBs on early tumors, especially after endoscopic resection. The aim of our study is to evaluate the value of the MTB after endoscopic resection of malignant tumors of the gastrointestinal tract.

METHODS

We retrospectively analyzed all endoscopically resected malignant tumors in our department between 2011 and 2019, focusing on the existence of an MDT recommendation after endoscopic resection, the MDT adherence to the current guidelines, and the implementation of the recommendation by the patients.

RESULTS

We identified 198 patients fulfilling our inclusion criteria, of whom 168 (85%) were discussed in the MDT after endoscopic resection. In total, 155 of the recommendations (92%) were in accordance with the current guidelines, and 147 (88%) of them were implemented by the patients. The MDT discussion itself did not influence the overall survival, whereas the implementation of the MTB recommendation was associated with a significantly better prognosis. Deviations of the MDT recommendation from the guidelines had no effect on the overall survival.

CONCLUSIONS

The discussion of endoscopically resected malignant tumors in the MTB is crucial for the treatment of patients with this type of cancer, since the implementation of the MTB recommendation, even if it deviates from the current guidelines, improves the prognosis.
