Abstract

Background: The t (11;14) (q13;32) translocation [t (11;14)] is present in ∼20% of patients with newly diagnosed multiple myeloma (NDMM), but studies examining its prognostic ability have yielded divergent results, and data are lacking on outcomes from first-line therapy.

Patients and methods: Data from the Connect MM Registry, a large US, multicenter, prospective observational cohort study of patients with NDMM were used to examine the effect of t (11;14) status on first-line therapy outcomes in the Overall population (n = 1574) and race groups (African American [AA] vs. non-African American [NAA]).

Results: Baseline characteristics were generally similar between patients with (n = 378) and without (n = 1196) t (11;14). Prevalence of t (11;14) was similar by race (AA, 27%; NAA, 24%). In the overall population, regardless of first-line therapy, t (11;14) status did not affect progression-free survival (hazard ratio, 1.02; P = 0.7675) or overall survival (hazard ratio, 0.99; P = .9417). AA patients with t (11;14) had higher likelihood of death (Nominal Cox regression P = .0298) vs. patients without t (11;14).

Conclusions: Acknowledging observational study and inferential limitations, this exploratory analysis of a predominantly community-based population suggests that t (11;14) is a neutral prognostic factor in the general MM population but may be a negative factor for overall survival in AA patients.
