Survival curves of stage A patients with B-CLL.

One hundred twenty-two patients from date of diagnosis (A) and 113 from date of CD38 estimation (B), censored for deaths unrelated to B-CLL. (A) CD38⁺(, n = 45); CD38⁻ (●, n = 77); mutatedIgV_H genes (○, n = 88); unmutatedIgV_H genes (▪, n = 34). (B) CD38⁺(, n = 41); CD38⁻ (●, n = 72); mutatedIgV_H genes (○, n = 84); unmutatedIgV_H genes (▪, n = 29). Numbers of patients analyzed by the 2 curves are different because 9 patients progressed beyond stage A between diagnosis and estimation of CD38.
