CLL Rai Stage: Treatment Free

Slide 5

November 2008

This slide shows a Kaplan-Meyer graph for patients with CLL and distributed by Rai stage. One can see that those patients with low-risk Rai stage disease don’t reach a 50% treatment-free point until approximately 8 years after diagnosis.

This falls to approximately 2-3 years for those with an intermediate risk, for as one can see that virtually all patients in high risk disease based on Rai staging require treatment early on in the course of their disease.
