Objective: Interdisciplinary cooperation is essential in treating and following up cancer disease. The primary objective of multidisciplinary tumor councils (MDTCs) is to identify the most suitable and effective treatment strategies for cancer patients through the collective decision-making of experts in oncology. MDTC plays a key role in breaking traditional taboos, providing the most up-to-date approach to the patient, sharing responsibility and accountability, and encouraging interdisciplinary communication and collaboration. Material and Methods: In this study, the perspectives, expectations, and experiences of medical oncologists regarding tumor boards were evaluated. The survey consisted of 10 questions and was conducted as an online survey at the '7th National Immunotherapy and Oncology Congress'. This study was cross-sectional and online. While those who were actively working as medical oncologists and those who wanted to voluntarily participate in the survey were included in the study, those who were not medical oncologists, those who were not actively working, and those who worked in private clinics were not included in the study. Participants were asked various questions about multidisciplinary tumor boards. They were asked about the specialties they most needed on the boards, the other clinics participating in the boards, and the clinics they felt were essential. The necessity of genetic clinics and molecular boards in shaping the future of oncology through molecular assessments was also assessed. The impact of board decisions on patient treatment and management was investigated. Results: A total of 624 oncologists participated in the survey. The majority of the participants were young oncologists. Most participants worked in tertiary healthcare units, including university hospitals and training and research hospitals. Almost all of the participants stated that they did MDTC. The most frequent and regular councils are; thoracic cancers and gastrointestinal cancers. The most needed and hard to reach branch was the medical genetics department. Conclusion: Cancer treatment is a complex process that cannot be confined to a single expertise. Multidisciplinary tumor boards (MDTB) are one of the cornerstones of a comprehensive approach to cancer treatment. In multidisciplinary tumor boards, various topics such as medical treatment planning for patients, diagnosis, surgical and radiotherapy planning, side effect management, and palliative care can be examined. MDTB not only provides effective treatment for cancer patients from a broad perspective but also ensures rapid and comprehensive solutions in case of potential complications.
