Fig. 5: Impact of TRAF3 mutations in ultra-high risk myeloma patients.

A Survival plot of the 13 ultrahigh-risk patients in our cohort showed that patients with TRAF3 mutations may have improved outcomes, although this did not reach significance in our series. However, the prognostic significance of TRAF3 mutations was later explored in the CoMMpass series for confirmation. B Globally, TRAF3 wild-type patients in the CoMMpass cohort had a significantly worse PFS compared to TRAF3 mutated patients. C From the CoMMpass series, patients that had a sFLCr > 100 at diagnosis and experienced disease progression at any time (N = 181) were selected. In this high-risk subpopulation, TRAF3 wild-type patients also showed dismal prognosis with a significantly shorter TTP.
