To optimize multidisciplinary approach, we included an Advisory Committee which will protect the multidisciplinary view and to discuss how to transport information and material between the different specialties. 

The Advisory Committee consists of Oncologists, Gastroenterologists, Surgeons and Radiologists. To improve the quality of the clinical practice, it should be standardized what and how information and specimen should transport from specialty to specialty (see figure). Questions regarding what the Pathologist need from the preoperative biopsy, what information does the surgeon need from the biopsy, what parts should the surgeon mark and how should the specimen be preserved and send to the pathologists, what information does the Oncologist need, etc. All these and more detailed questions will be standardized in a multidisciplinary approach.
