Overview
According to the Rai Staging System, there are five stages of chronic lymphocytic leukemia based on the degree of lymphocytosis, hemoglobin level, platelets level, presence of splenomegaly, and presence of lymphadenopathy. According to the Binet Staging System, there are three stages of chronic lymphocytic leukemia based on the degree of lymphocytosis, the presence of anemia or thrombocytopenia, and the involvement of three or more lymph node regions. The tumor stage is considered one of the important factors that determine the optimal management protocol of chronic lymphocytic leukemia patients.
Staging System
Rai Staging System:
According to the Rai Staging System, there are five stages of chronic lymphocytic leukemia based on the degree of lymphocytosis, hemoglobin level, platelets level, presence of splenomegaly, and presence of lymphadenopathy.[1]
Stage | Hemoglobin Level | Platelets Level | Lymphocytosis | Splenomegaly | Lymphadenopathy | Median Survival |
---|---|---|---|---|---|---|
Stage 0 |
>11 g/dL |
>100,000/L |

The staging is further modified into 3 groups:[2]
- Low Risk: Stage 0
- Intermediate Risk: Stages 1 and 2 combined
- High Risk: Stage 3 and 4 combined
Binet Staging System
According to the Binet Staging System, there are three stages of chronic lymphocytic leukemia based on the degree of lymphocytosis, the presence of anemia or thrombocytopenia, and the involvement of three or more lymph node regions.[3]
Stage | Lymphocytosis | Anemia or Thrombocytopenia | Lymphadenopathy | Median Survival |
