Survival curves for CD5⁺CD10⁻ large B-cell lymphomas. De novo CD5⁺CD10⁻ DLBCL without an intravascular/sinusoidal pattern (DLBCL-NOS) showed significantly better survival than either de novo CD5⁺CD10⁻ DLBCL with an intravascular/sinusoidal pattern (DLBCL with IVL pattern; log-rank P = .018) or CD5⁺CD10⁻ IVLBCL (P < .001). No significant difference for survival was found between CD5⁺CD10⁻ IVLBCL and DLBCL with an IVL pattern (P = .158).
