Figure 1. VLA-4 and CD38 expression are associated in CLL cells.

Figure 1

Percent VLA-4+ correlated to percent CD38+ CLL cells of 144 CLL patients (Spearman's Rho  =  .6293, P<.0001). Red lines depict cut-offs between low and high-risk samples for each parameter, separating the cohort into four subgroups. Of note, 31 patients in our cohort (21.5%) showed discordant VLA-4 and CD38 risk.
