Conclus<strong>io</strong>ns<br />

Chemoimmunotherapy has had a dramatic impact on<br />

the outcome of patients with CLL, has improved CR<br />

rates, eradicates minimal residual disease, and has<br />

resulted in improved survival. Remiss<strong>io</strong>ns with frontline<br />

therapy last for years and data are now emerging that<br />

more effective frontline regimens are associated with<br />

improved overall survival in CLL. Studies are also<br />

assessing whether specific treatments are indicated for<br />

groups of patients with specific cytogenetic abnormalities.<br />

However, not all patients can tolerate aggressive<br />

chemo-immunotherapy regimens, and patients continue<br />

to relapse so new drugs are needed to effect cure in<br />

these patient populat<strong>io</strong>ns. The encouraging array of<br />

ongoing clinical trials and investigat<strong>io</strong>nal drugs, many of<br />

which have novel mechanisms of act<strong>io</strong>n, engender great<br />

optimism that cure of CLL may be accomplished within<br />

the next 20 years.<br />
