Does the SORG Algorithm Predict 5-year Survival in Patients with Chondrosarcoma? An External Validation

Background We developed a machine learning algorithm to predict the survival of patients with chondrosarcoma. The algorithm demonstrated excellent discrimination and calibration on internal validation in a derivation cohort based on data from the Surveillance, Epidemiology, and End Results (SEER) registry. However, the algorithm has not been validated in an independent external dataset. Questions/purposes Does the Skeletal Oncology Research...
