Effect of pretreatment and posttreatment radiographic parameters on PFS. Elevated pretreatment MTV (A) and TLG (B) were associated with inferior PFS. Posttherapy increased CT residual mass volume (C), SUV_max (D), and end-of-therapy Deauville score (E-F) predicted inferior PFS. The combination of pretreatment TLG and posttreatment Deauville score (G-H) were also associated with decreased PFS.
