Survival after salvage therapy. (A) Survival after salvage therapy according to regimen received (n = 136; P = .013). (B) Survival after salvage therapy according to regimen received, in patients with first remission of <3 years (n = 42, P = .93). Colored dots represent transplantation status of survivors. (C) Survival after salvage therapy according to the regimen received in patients with remission of ≥3 years (n = 94). FCR or lenalidomide-based regimens were associated with improved survival (P < .001 vs rest).
