A Prospective Observational Study on the Structuring Process and Implementation of a Large Regional, Inter-hospital, Virtual Multidisciplinary Tumor Board on Prostate Cancer

Background/aim: At present, multidisciplinary tumor boards (MDTB) are considered best practice in oncology. However, web-based virtualization of MDTB may increase participation in meetings, the number of cases discussed, and adherence to guidelines, deliver better treatment, and eventually improve outcomes for patients with prostate cancer. Patients and methods: This is an observational study focused on exploring the structuring process and implementing a multi-institutional virtual MDTB in Sicily, Italy. Other endpoints included the analysis of cooperation between participants, adherence to guidelines, patient outcomes, and patient satisfaction. Results: Overall, 126 patients were referred to the virtual MDTB for a total of 302 cases discussed in an 18-month period. Nearly 45% of cases were referred from general hospitals or tertiary centers, 38% from comprehensive cancer centers, and only 17% from academic ones. Most health professional participants (95%) reported eliminating geographical barriers and consequently reducing costs and saving time as key advantages of virtual meetings over face-to-face ones. Using a specifically designed platform for virtual MDTBs was another excellent point, especially to geolocate clinical trials and time-lapse data storage. The majority of referred patients had stage T 3-4 prostate cancer (79%). Overall, 71% of proposals discussed were approved unchanged, while 19% changed after the virtual MDTB discussion. Debated points were mostly radiologic, surgical, medical, or radiation treatment-related issues. In particular, the prescriptive appropriateness of positron emission tomography with 68Ga-prostatic specific membrane antigen, newer drugs, radiation versus surgical approach, stage T3-4 cases, and adjuvant therapy represented the most debated issues. The proposed diagnostic and/or therapeutic options were controlled for adherence to the guidelines and/or updated scientific evidence. Overall, 98% of approved proposals and changes were in line with the guidelines. Overall, most participants felt virtual MDTB was very useful and case discussions led to a major change of strategy in 19% of cases. Conclusion: Virtual MDTBs are a very useful way to achieve best management of prostate cancer while saving time and fostering cooperation.
