Revisiting the Role of Radiation Therapy in Chondrosarcoma: A National Cancer Database Study

Figure 4

Multivariate Cox proportional hazards regression for independent predictors of mortality in patients with chondrosarcoma. Forest plot of hazard ratios and 95% confidence intervals displayed for patient, tumor, and treatment variables. Base model performed with radiation type variable categorized by both radiation modality and dose. ²Model repeated to assess the impact of margin status on the survival effect of radiation therapy. ³Radiation modalities of EBRT and IMRT were combined and compared with PBT.
