Prognostication for Patients Receiving Palliative Radiation Therapy

Estimation of patient prognosis plays a central role in guiding decision making for the pal-liative management of metastatic disease, and a number of statistical models have been developed to provide survival estimates for patients in this context. In this review, we dis-cuss several well-validated survival prediction models for patients receiving palliative radiotherapy to sites outside of the brain. Key considerations include the type of statistical model, model performance measures and validation procedures, studies' source popula-tions, time points used for prognostication, and details of model output. We then briefly discuss underutilization of these models, the role of decision support aids, and the need to incorporate patient preference in shared decision making for patients with metastatic disease who are candidates for palliative radiotherapySemin Radiat Oncol 33:104-113 (c) 2023 The Author(s).
