Study Notes
Chronic Lymphocytic Leukemia (CLL) Survival
- Survival for patients with CLL can vary significantly, ranging from 2 to over 20 years.
- The median survival rate for CLL patients is approximately 10 years.
- Patients diagnosed at Rai stage 0-II have a favorable prognosis, potentially surviving between 5 to 20 years without treatment.
Prognostic Factors
- Lymphocyte doubling time serves as a crucial prognostic factor in CLL.
- This measure indicates the months required for the absolute lymphocyte count to double.
- Untreated patients exhibiting a shorter lymphocyte doubling time tend to have a more aggressive form of CLL.
