Multidisciplinary management tumor boards are now conducted worldwide for the management of patients with cancer. Studies evaluating their influence on decision making and patient outcome are limited; however, single-center studies have reported significant changes in diagnosis and treatment plans. A survey from Arabic countries showed widespread use and reliance on tumor boards for decision making. A recent multi-institutional survey of veteran affairs (VA) hospitals in the United States found limited association between the presence of tumor boards and care and outcomes. The Cancer Care Outcomes Research and Surveillance Consortium looked at the association between tumor board features and measures of quality of care. Results of overall survival among the patients of these physicians participating in tumor boards is ongoing, but preliminary results are outlined along with a recent ASCO survey of international members on the presence, utilization, and influence of tumor boards in this article. Tumor boards allow for implementation of clinical practice guidelines and may help capture cases for clinical trials. Efforts to improve preparations, structure, and conduct of tumor boards, research methods to monitor their performance, teamwork, and outcomes are outlined also in this article. The concept of mini-tumor boards and more efficient methods for MDM in countries with limited resources are also discussed. In suboptimal settings, such as small community hospitals, rural areas, and areas with limited resources, boundaries in diagnosis and management can be overcome, or at least improved, with tumor boards, especially with the use of video-conferencing facilities. Studies from the United Kingdom showed that special training of multidisciplinary teams (MDT) led to better team dynamics and communication, improved patient satisfaction, and improved clinical outcome. The weight of the benefits versus the time and effort spent to improve efficiency, patient care, and better time management in the United States and in the international oncology community is also reviewed in this article.
PurposeMultidisciplinary tumor boards (MDTBs) are universally recommended, but recent literature has challenged their efficiency.MethodsThe American Society of Clinical Oncology (ASCO) conducted a survey of a randomly selected cohort of international ASCO members. The survey was built on SurveyMonkey and was sent via e-mail to a sample of 5,357 members.ResultsIn all, 501 ASCO members practicing outside the United States responded, and 86% of them participated in MDTBs at their own institutions. Those who attended represented a variety of disciplines in 70% to 86% of all MDTBs. The majority of MDTBs held weekly specialty and/or general meetings. Eighty-nine percent of 409 respondents attended for advice on treatment decisions. Survey respondents reported changes of 1% to 25% in treatment plans for 44% to 49% of patients with breast cancer and in 47% to 50% of patients with colorectal cancer. They reported 25% to 50% changes in surgery type and/or treatment plans for 14% to 21% of patients with breast cancer and 12% to 18% of patients with colorectal cancer. Of the 430 respondents 96% said overall benefit to patients was worth the time and effort spent at MDTBs, and 96% said that MDTBs have teaching value. Mini tumor boards held with whatever types of specialists were available were considered valid. In all, 94.8% (425 of 448) said that MDTBs should be required in institutions in which patients with cancer are treated.ConclusionMDTBs are commonplace worldwide. A majority of respondents attend them to obtain recommendations, and they report changes in patient management. Change occurred more frequently with nonmedical oncologists and with physicians who had less than 15 years in practice. MDTBs helped practitioners make management decisions. Mini tumor boards may improve time efficiency and are favored when the full team is not available. Suggestions for improving MDTBs included making them more efficient, better selection and preparation of cases, choosing an effective team leader, and improving how time is used, but more research is needed on ways to improve the efficiency of MDTBs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
