Evaluating and Predicting the Probability of Death in Patients with Non-Metastatic Osteosarcoma: A Population-Based Study

Osteosarcoma is a common bone tumor that can be difficult to treat, especially when it spreads. This study aimed to identify factors that affect survival in patients with osteosarcoma that hasn't spread. The researchers used a large database to analyze information from patients diagnosed with non-metastatic osteosarcoma between 2005 and 2014. They looked at factors like age, tumor size, and grade to see how they affected survival rates. The study created nomograms, which are tools that can help predict a patient's probability of survival based on these factors. These nomograms were found to be more accurate than older staging systems in predicting survival.

• 1
  Age, tumor size, grade, and AJCC T staging were independent prognostic factors for OS and CSS.
• 2
  Nomograms based on multivariable models worked well in predicting the probability of death for patients with non-metastatic osteosarcoma.
• 3
  Relatively young age and low histopathological grade were favorable factors for both OS and CSS.
