There is little association of multidisciplinary tumor boards with measures of use, quality, or survival, and measuring only the presence of tumor boards may not be adequate in determining their effects on cancer care, according to a study published Dec. 28 in the Journal of the National Cancer Institute. Tumor board reviews offer a multidisciplinary approach to treatment planning, which encompasses doctors from many specialties reviewing and discussing the medical condition and the treatment of patients. Even though the use of tumor boards is widespread, there is little data on how it affects cancer care.
