Palliative Appropriateness Criteria: A Pragmatic Method to Evaluate the Suitability of Palliative Radiotherapy Fractionation

To describe a novel metric to aid clinical decision making between shorter versus longer palliative radiotherapy (PRT) regimens using objective patient factors. Patients receiving PRT at a single institution between 2014 and 2018 were reviewed. The time between PRT start and finish was calculated and divided by overall survival (in days from start of PRT) to generate the percent of remaining life (PRL). This value was compared across various clinical factors using the Kruskal-Wallis test. Factors identified with a significance level
