This document reports on the datasets and a data structure for reporting clinical and biological evaluation metrics (CBEMs). The reporting of radiation dose estimates is outside the scope of this document.

This document is applicable to CBEMs for external-beam radiation therapy (EBRT) modalities, but not CBEMs for brachytherapy or molecular radiotherapy.

Various types of radiotherapy treatment modalities are available for cancer care. Consequently, there is a growing awareness of the need for objective schemes that will contribute to enable the selection of an appropriate radiotherapy treatment modality for individual patients. The use of CBEMs, the metrics associated with a certain radiotherapytreatment plan for a patient, is attracting attention for clinical purposes in the field of EBRT. In anticipation of the clinical use of CBEMs, the importance of research on clinical and scientific aspects of CBEMs is increasing, in concert with the importance of establishing a standardized data format for reporting of specifics of a CBEM.
