Key Points

To externally validate the Oswestry Spinal Risk Index in radiotherapy patients.
Conducted an external validation of OSRI in a cohort of radiotherapy patients
Analyzed correlation between predicted and actual survival
Emphasized the index's simplicity and accuracy
Strong correlation found between predicted and actual survival
OSRI proved valuable for rapid decision-making in emergency settings
High accuracy reinforces OSRI's practical application among radiotherapy patients

Abstract

This study is the first to externally validate the Oswestry Spinal Risk Index (OSRI) specifically in patients treated exclusively with radiotherapy. Unlike previous validations, which included patients managed surgically or with combined modalities, our cohort focused solely on radiotherapy. We found a strong correlation between predicted and actual survival, highlighting the OSRI's simplicity, accuracy and its practical value for rapid decision-making in emergency settings.
