Probability of survival from the date of diagnosis among patients with a V_H homology less than 97% or 97% or greater and less than 98% or 98% or greater.

(A) Estimated median survival time for the V_Hhomology 97% or greater group was 79 months. The last observed death in the V_H homology less than 97% group was after 152 months of follow-up time (survival probability, 56%). (B) When only patients diagnosed at Binet stage A were evaluated, the estimated median survival times for the V_Hhomology 97% or greater and the V_H homology less than 97% groups were 79 months versus not reached (last observed death after 152 months of follow-up time; survival probability, 53%). (C) Estimated median survival time for the V_Hhomology 98% or greater and less than 98% groups were 79 months and 152 months, respectively. (D) When only patients diagnosed at Binet stage A were evaluated, the estimated median survival times for theV_H homology 98% or greater andV_H homology less than 98% groups were 79 months versus 152 months.
